B) As a minimum, prior to installation and/or erection of pipe spools on the pipe racks and pipe supports the following is conducted:• Pipes are internally cleaned by air blowing and large diameters pipes are rag cleaned when possible.• Prefabricated pipe spools are visually inspected for cleanliness with all foreign material removed from ID.• Piping ends are covered after inspection to prevent unauthorized removal of end covers before making succeeding joints. C) Spool cleanliness checks prior to installation (best with mirror and natural sunlight) are identifiable as "clean". D) The covering of pipe ends is followed without exception daily.


C2Lines to be chemically cleaned are identified on the P&ID's and Line Index. Note: Identify spools requiring chemical cleaning and ensure high and low point vents and drains are installed.

SAES-L-350 Para. 15.4.3

C5

Ovality checks are performed to ensure roundness and alignment of piping (to meet 1.5 mm maximum misalignment tolerances). A) Piping ends out of round are identified at grade before installation in the overhead racks. (This prevents costly out of position work). B) The inspector checks/ensures others check that single lengths matched/welded in overhead racks have similar ovality readings. (A systematic plan results in better progress and improved quality) C) Ovality repairs are performed (at grade) prior to installation. (Ovality repair procedures are approved and force not exceeding yield strength or 30 ksi maximum for Carbon steel is applied.)

SAES-L-350 Para.

D Coating Sequence before Installation

D1

External coating is complete prior to installation as follows: A) Flange faces & bolt hole surfaces (except gasket seating area) B) Valve (bolted types) flange faces (except gasket seating area) • Once installed, flange faces and bolt hole surfaces are inaccessible for coating unless disassembled (impractical/costly). H-Std Tables require exterior surfaces be coated. C) Contact point surfaces between spools and supports have received a final top coat when lifting or rolling piping is impractical.

SAES-H-001 Section 5

D2

Internal coating is complete prior to installation as follows: A) Spools internally coated and cleared can be installed. B) Where field welding and PWHT applications apply, Spools requiring field coating repairs must be disassembled for later internal coating where required and access and sequence of coating repairs is well planned and supported by procedures.

SAES-H-001 Section 5

E On-Plot Material Handling and Storage

E1

Pipe handling procedure including equipment used for handling is Company approved and good practice is in effect as follows: A) Material is not rolled/dropped off trucks during unloading. B) Material is stacked properly to protect pipe and coatings. C) Slings are nylon or similar and wire rope slings are not used. D) Metal hooks are padded to prevent contact damage to coating E) Internally coated fittings are handled on the OD only. F) Bevel protectors remain intact and don't damage coatings.


E2

Components are protected from mechanical damage with welding ends protected with suitable wood, plastic, or metal covers and all fittings packaged in steel-banded wooden crates or secured to skids in staging areas for field use as follows: A) All fittings (02-SAMSS-005, Section 10) B) All flanges (02-SAMSS-011, Section 10)
