Properties of graphite tubes with

carbon fiber reinforcement

Increased bursting pressure

The tube becomes more resistant to steam hammerand service pressures above the permitted limit itsbursting pressure at room temperature being raisedto 130 to 140 of that of a non-reinforced tubedepending on the tube dimensions

Carbon Fiber-Reinforced Componentsfor Increased Safety

In developing the carbon fiber reinforcement of components (DIA-BON HF) SGL Group has found a way to increase the operationalreliability of DIABON graphite components appreciably and expandtheir range of application under high-stress conditions The fiber rein-forcement is used for tube sheets headers and column sections andespecially for tubes

Resistance of a cracked tube to leakage

Should a longitudinal crack occur in a DIABON HFtube as a result of overstressing the tube will not

allow any major leakage up to a differential pres-sure of some 2 to 5 bar In all instances the rein-forcement prevents any spalling from the tube anda consequent escape of product in large quantities Usually theequipment can continue in operation without interruption until the nextplanned shutdown

Multi-Tube Bundle Heat Exchangersmade from DIABONreg Process Equipment Graphite

A new generation of heat exchangers

Unlike conventional products our DIABON multi-tube bundle heat exchangers feature an exchangesurface area distributed over several identical small

tube bundles instead of a single large bundle

Separate graphite tube bundles are incorporatedin a shell made from carbon steel One or more of these elements can be integrated in a frame of sup-port plates The tube bundles are sealed againstboth the steel flanges and headers with O-ring sealsmade from a high-quality sealing material

The special design features make for a wholerange of advantages

Technical

High performance combined with small heatexchange area

Savings in heat exchange area of up to 40 Modular design Multi-mode operation in a single unit Flexibility in use Connection scheme adjustable to requirements Stress-free installation of tube bundles

DIABONreg bundles of a multi-tube bundle heat exchanger

The special design of multi-tube bundle heatexchangers allows single or multiple counter-currentflow or several different applications in a singleunit eg in

condensation residual gas and condensate sub-cooling

using different cooling media for the purpose

7232019 SGL-PT-Brochure-Graphite Shell Tube Heat Exchangers

httpslidepdfcomreaderfullsgl-pt-brochure-graphite-shell-tube-heat-exchangers 1116

ndash sliding seal to compensate for thermalexpansionndash minimal axial and radial movementndash short tightening distances

Identical and standardized assemblies(tube bundles modules headers etc)

Practical sealing system with reliable O-ringsand sealing cords in high-quality materials

Flexible design allowingndash co-current-flow operationndash multi-mode operations

Operational advantages

Vertical and horizontal installation Antifouling properties Optimum design for CIP procedures

(Cleaning in Place)

Meets cGMP requirements(current Good Manufacturing Practices)

Automatic ventilation and emptyingpossible

Long servicing intervals Ease of handling Ease of servicing Maximum operational reliability Optional inspection glass allows

process control

DIABONreg multi-tube bundle heat exchanger (5 bundles)

Another special advantage of this design is that itallows pure counter-current flow Compared withstandard equipment the temperature differentialcan be used to full advantage Moreover the de-

sign can be individually adapted and optimized foreach application The resulting savings in heatexchange area can be as much as 40

The equipment design is optimized to allow an idealinlet flow profile for the cylindrical tube sections Asa result flow conditions for each tube bundle areidentical without dead spaces or areas exposed toundercurrents and turbulence This is why our equip-ment displays excellent antifouling behavior when

used for media with an inherent fouling tendency

DIABONreg multi-tube bundle heat exchanger (3 bundles)

A further advantage of this design is its ease of handling Since the heat exchanger has only a fewcomponents dismantling is just a short sequenceof operations that can be easily performed by theoperators themselves

The availability of the equipment can be increasedsignificantly by keeping spare bundles in stockDuring heat exchanger cleaning operations tubebundles can be replaced as required in a minimumof time This ensures nearly 100 availability of the

equipment and associated plantsDamaged tube bundles can be re-paired at any time and even repeat-

edly thereby minimizing the cost of servicing

Multi-tube bundle heat exchangers are suitablefor a wide range of chemical processes when

used as Coolers Heaters Condensers Evaporators (forced and natural circulation) Falling-film evaporators Integrated equipment for condensing

with simultaneous residual gas cleaning(cold trap)

Heating and cooling of pickling lines

Properties of graphite tubes with

carbon fiber reinforcement

Increased bursting pressure

The tube becomes more resistant to steam hammerand service pressures above the permitted limit itsbursting pressure at room temperature being raisedto 130 to 140 of that of a non-reinforced tubedepending on the tube dimensions

Carbon Fiber-Reinforced Componentsfor Increased Safety

In developing the carbon fiber reinforcement of components (DIA-BON HF) SGL Group has found a way to increase the operationalreliability of DIABON graphite components appreciably and expandtheir range of application under high-stress conditions The fiber rein-forcement is used for tube sheets headers and column sections andespecially for tubes

Resistance of a cracked tube to leakage

Should a longitudinal crack occur in a DIABON HFtube as a result of overstressing the tube will not

allow any major leakage up to a differential pres-sure of some 2 to 5 bar In all instances the rein-forcement prevents any spalling from the tube anda consequent escape of product in large quantities Usually theequipment can continue in operation without interruption until the nextplanned shutdown

Multi-Tube Bundle Heat Exchangersmade from DIABONreg Process Equipment Graphite

A new generation of heat exchangers

Unlike conventional products our DIABON multi-tube bundle heat exchangers feature an exchangesurface area distributed over several identical small

tube bundles instead of a single large bundle

Separate graphite tube bundles are incorporatedin a shell made from carbon steel One or more of these elements can be integrated in a frame of sup-port plates The tube bundles are sealed againstboth the steel flanges and headers with O-ring sealsmade from a high-quality sealing material

The special design features make for a wholerange of advantages

Technical

High performance combined with small heatexchange area

Savings in heat exchange area of up to 40 Modular design Multi-mode operation in a single unit Flexibility in use Connection scheme adjustable to requirements Stress-free installation of tube bundles

Another special advantage of this design is that itallows pure counter-current flow Compared withstandard equipment the temperature differentialcan be used to full advantage Moreover the de-

sign can be individually adapted and optimized foreach application The resulting savings in heatexchange area can be as much as 40

The equipment design is optimized to allow an idealinlet flow profile for the cylindrical tube sections Asa result flow conditions for each tube bundle areidentical without dead spaces or areas exposed toundercurrents and turbulence This is why our equip-ment displays excellent antifouling behavior when

used for media with an inherent fouling tendency

DIABONreg multi-tube bundle heat exchanger (3 bundles)

A further advantage of this design is its ease of handling Since the heat exchanger has only a fewcomponents dismantling is just a short sequenceof operations that can be easily performed by theoperators themselves

The availability of the equipment can be increasedsignificantly by keeping spare bundles in stockDuring heat exchanger cleaning operations tubebundles can be replaced as required in a minimumof time This ensures nearly 100 availability of the

equipment and associated plantsDamaged tube bundles can be re-paired at any time and even repeat-

edly thereby minimizing the cost of servicing

Multi-tube bundle heat exchangers are suitablefor a wide range of chemical processes when

used as Coolers Heaters Condensers Evaporators (forced and natural circulation) Falling-film evaporators Integrated equipment for condensing

with simultaneous residual gas cleaning(cold trap)

Heating and cooling of pickling lines

Properties of graphite tubes with

carbon fiber reinforcement

Increased bursting pressure

The tube becomes more resistant to steam hammerand service pressures above the permitted limit itsbursting pressure at room temperature being raisedto 130 to 140 of that of a non-reinforced tubedepending on the tube dimensions

Resistance of a cracked tube to leakage

Should a longitudinal crack occur in a DIABON HFtube as a result of overstressing the tube will not

allow any major leakage up to a differential pres-sure of some 2 to 5 bar In all instances the rein-forcement prevents any spalling from the tube anda consequent escape of product in large quantities Usually theequipment can continue in operation without interruption until the nextplanned shutdown

Multi-Tube Bundle Heat Exchangersmade from DIABONreg Process Equipment Graphite

A new generation of heat exchangers

Unlike conventional products our DIABON multi-tube bundle heat exchangers feature an exchangesurface area distributed over several identical small

tube bundles instead of a single large bundle

Separate graphite tube bundles are incorporatedin a shell made from carbon steel One or more of these elements can be integrated in a frame of sup-port plates The tube bundles are sealed againstboth the steel flanges and headers with O-ring sealsmade from a high-quality sealing material

The special design features make for a wholerange of advantages

Technical

High performance combined with small heatexchange area

Savings in heat exchange area of up to 40 Modular design Multi-mode operation in a single unit Flexibility in use Connection scheme adjustable to requirements Stress-free installation of tube bundles

DIABONreg bundles of a multi-tube bundle heat exchanger

The special design of multi-tube bundle heatexchangers allows single or multiple counter-currentflow or several different applications in a singleunit eg in

condensation residual gas and condensate sub-cooling

using different cooling media for the purpose

DIABONreg multi-tube bundle heat exchanger (5 bundles)

Another special advantage of this design is that itallows pure counter-current flow Compared withstandard equipment the temperature differentialcan be used to full advantage Moreover the de-

sign can be individually adapted and optimized foreach application The resulting savings in heatexchange area can be as much as 40

The equipment design is optimized to allow an idealinlet flow profile for the cylindrical tube sections Asa result flow conditions for each tube bundle areidentical without dead spaces or areas exposed toundercurrents and turbulence This is why our equip-ment displays excellent antifouling behavior when

used for media with an inherent fouling tendency

DIABONreg multi-tube bundle heat exchanger (3 bundles)

A further advantage of this design is its ease of handling Since the heat exchanger has only a fewcomponents dismantling is just a short sequenceof operations that can be easily performed by theoperators themselves

The availability of the equipment can be increasedsignificantly by keeping spare bundles in stockDuring heat exchanger cleaning operations tubebundles can be replaced as required in a minimumof time This ensures nearly 100 availability of the

equipment and associated plantsDamaged tube bundles can be re-paired at any time and even repeat-

edly thereby minimizing the cost of servicing

Multi-tube bundle heat exchangers are suitablefor a wide range of chemical processes when

used as Coolers Heaters Condensers Evaporators (forced and natural circulation) Falling-film evaporators Integrated equipment for condensing

with simultaneous residual gas cleaning(cold trap)

Heating and cooling of pickling lines

Carbon Fiber-Reinforced Componentsfor Increased Safety

In developing the carbon fiber reinforcement of components (DIA-BON HF) SGL Group has found a way to increase the operationalreliability of DIABON graphite components appreciably and expandtheir range of application under high-stress conditions The fiber rein-forcement is used for tube sheets headers and column sections andespecially for tubes

Resistance of a cracked tube to leakage

Should a longitudinal crack occur in a DIABON HFtube as a result of overstressing the tube will not

allow any major leakage up to a differential pres-sure of some 2 to 5 bar In all instances the rein-forcement prevents any spalling from the tube anda consequent escape of product in large quantities Usually theequipment can continue in operation without interruption until the nextplanned shutdown

Multi-Tube Bundle Heat Exchangersmade from DIABONreg Process Equipment Graphite

A new generation of heat exchangers

Unlike conventional products our DIABON multi-tube bundle heat exchangers feature an exchangesurface area distributed over several identical small

tube bundles instead of a single large bundle

Separate graphite tube bundles are incorporatedin a shell made from carbon steel One or more of these elements can be integrated in a frame of sup-port plates The tube bundles are sealed againstboth the steel flanges and headers with O-ring sealsmade from a high-quality sealing material

The special design features make for a wholerange of advantages

Technical

High performance combined with small heatexchange area

Savings in heat exchange area of up to 40 Modular design Multi-mode operation in a single unit Flexibility in use Connection scheme adjustable to requirements Stress-free installation of tube bundles

Another special advantage of this design is that itallows pure counter-current flow Compared withstandard equipment the temperature differentialcan be used to full advantage Moreover the de-

sign can be individually adapted and optimized foreach application The resulting savings in heatexchange area can be as much as 40

The equipment design is optimized to allow an idealinlet flow profile for the cylindrical tube sections Asa result flow conditions for each tube bundle areidentical without dead spaces or areas exposed toundercurrents and turbulence This is why our equip-ment displays excellent antifouling behavior when

used for media with an inherent fouling tendency

A further advantage of this design is its ease of handling Since the heat exchanger has only a fewcomponents dismantling is just a short sequenceof operations that can be easily performed by theoperators themselves

The availability of the equipment can be increasedsignificantly by keeping spare bundles in stockDuring heat exchanger cleaning operations tubebundles can be replaced as required in a minimumof time This ensures nearly 100 availability of the

equipment and associated plantsDamaged tube bundles can be re-paired at any time and even repeat-

edly thereby minimizing the cost of servicing

Multi-tube bundle heat exchangers are suitablefor a wide range of chemical processes when

used as Coolers Heaters Condensers Evaporators (forced and natural circulation) Falling-film evaporators Integrated equipment for condensing

with simultaneous residual gas cleaning(cold trap)

DIABONreg multi-tube bundle heat exchanger (5 bundles)

Another special advantage of this design is that itallows pure counter-current flow Compared withstandard equipment the temperature differentialcan be used to full advantage Moreover the de-

sign can be individually adapted and optimized foreach application The resulting savings in heatexchange area can be as much as 40

The equipment design is optimized to allow an idealinlet flow profile for the cylindrical tube sections Asa result flow conditions for each tube bundle areidentical without dead spaces or areas exposed toundercurrents and turbulence This is why our equip-ment displays excellent antifouling behavior when

used for media with an inherent fouling tendency

DIABONreg multi-tube bundle heat exchanger (3 bundles)

A further advantage of this design is its ease of handling Since the heat exchanger has only a fewcomponents dismantling is just a short sequenceof operations that can be easily performed by theoperators themselves

The availability of the equipment can be increasedsignificantly by keeping spare bundles in stockDuring heat exchanger cleaning operations tubebundles can be replaced as required in a minimumof time This ensures nearly 100 availability of the

equipment and associated plantsDamaged tube bundles can be re-paired at any time and even repeat-

edly thereby minimizing the cost of servicing

Multi-tube bundle heat exchangers are suitablefor a wide range of chemical processes when

used as Coolers Heaters Condensers Evaporators (forced and natural circulation) Falling-film evaporators Integrated equipment for condensing

with simultaneous residual gas cleaning(cold trap)

Heating and cooling of pickling lines
