FOREWORD

This Indian Standard (First Revision) was adopted by the Bureau of Indian Standards, after the draft finalized bythe Dyeing, Fin isbing and Allied Machinery and Accessories Sectional “Committee had been approved by theTextile Division Council. .

This standard was first published in 1992 and has been revised to include drying cylinders of 800 mm outsidediameter which are also commonly used in the industry. Besides, tolerances for cylindricity and total run-out havebeen mod fied as per latest industrial practices. Also requirement for anti-collapsible ring has been included .

Drying cylinder is a cylindrical shell fabricated from stainless steel sheet and is used for drying in textile processing.It is heated with steam supplied at a pressure up to 0.39 MPa (4.0 kgf/cm2). The steam loses its heat during theprocess of heat transfer to the surface of cylinder and in turn to the fabric being processed on the drying cylinder.The entire assembly of the drying cylinder comprising cylinder shell, side flanges, trunnions and their requiredjoints may have design features in accordance with IS 2825 ‘Code for unfired pressure vessels’.

The composition of the Committee responsible for formulation of this standard is given in Annex A,

For the purpose of deciding whether a particular requirement of this standard is complied with, the final value,observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance withIS 2: 1960 ‘Rules for rounding off numerical values (revised)’. The number of significant places retained in therounded off value should be the same as that of the specified value in this standard.

3 FACE LENGTH OF CYLINDER

The face length of cylinder shall match the nominalwidth of textile finishing machines for treatment oftextile fabrics in open width.

NOTE — Face length of cylinder is also called cylinder face

and is equal to the fabric width in millimetres plus a minimum

of200 mm.

4 MATERIALS

4.1 Shell

The cylinder shall be fabricated from stainless steelsheets equivalent to 04 Cr 18 Ni 10 (see IS 6911) orany other grade of stainless steel for better resistanceto corrosion.

4.2 Side Flanges

Side flanges shall be manufactured from tested steelplate according to IS 226.

5 COMPONENTS

5.1 Side Flanges (End Flanges)

Side flanges shall be either dished or flat and thicknessof material shall be according to design features ofIS 2825. The side flanges will be provided with aconcentric bore and number of holes on a concentriccircle to hold the trunnions of the cylinder (see Fig. 1).

5.2 Vacuum Breaker Valve.(Breather)

To safeguard the failure of cylinder shell againstvacuum during the process of condensation ofsteam,two vacuum breaker valves (air breather valve)manufactured from non-corrosive material with suitablefittings shall be provided at 180° on side flanges.

5.3 Drain-Cock

A drain cock manufactured tlom non-corrosive materialwith fittings, if any shall be provided for the purposeof draining the condensate completely from thecylinder.

5.4 Anti-collapsible Ring

The cylinder shall be provided with required numberof rings inside it to protect it from collapsing due tovacuum created inside the cylinder due to condensationof steam and non-working of vacuum breaker valvewhen inlet and outlet lines of the cylinder are air-tight.

Cylinder should be able to withstand at least 0.02 MPa(0.2 bar) pressure below the atmospheric pressure.

6 MANUFACTURE

6.1 The surface of stainless steel sheet of drying cylindershall be smooth finished including the welding of thelongitudinal seam and circumferential joint. Thelongitudinal seam and circumferential joint shall alsobe checked for welding strength as specified by thebuyer. The cylinder shell weldments shall be carriedout by argon arc welding process and shall be free fromdefects such as pin holes, under cuttings, unevensurface, improper weld finish, cavities, etc. Weldmentsof cylinder shell and side flanges shall be carried outpreferably by argon arc welding process or any otherstandard welding method. The.number of longitudinalseams shall be limited up to 2. The circumferentialjoint for cylinder shell should be avoided but in anycase it should not exceed one in number.

6.1.1 The surface finish shallbe2B(seeIS6911).

6.1.2 Surface treatlment of thecylinder likecoatingofP’lFE (Teflon) or by any other means shall be agreedto between the buyer and the manufacturer. In case oftreatment with PTFE the coating shall be 50 microns,Afitl.

6.2 The cylinder shell, trunnions and joints shall bechecked for their tightness and rendered leak proof bya suitable sealing gasket as agreed to between the buyer,and the manufacturer.

7 DIMENSIONS AND TOLERANCES

7.1 Dimensions

The stain less steel drying cylinder shall conform todimensions given in Table 1 when read with Fig. 1.
