ISO 9001:2000 MANUFACTURING SPECIFICATIONS FOR FUSIBOND PLASTIC LINED PIPE AND PLASTIC LINED FITTINGS 1. SCOPE 1.1 This standard covers FusiBond plastic lined pipe and plastic lined fittings lined with Polypropylene, PP, Kynar, PVDF, Halar, ECTFE, ETFE, PTFE, MPFA, and PFA. 2. MATERIALS AND MANUFACTURING STANDARDS 2.1 Pipe shall be.carbon steel schedule 10 through 80, (schedule 40 ERW standard) Maximum length is 20'-0". (ductile iron, galvanized or stainless special order) 2.2 Pipe grade may be E.R.W. (electric resistance welded) ASTM A-587, low carbon steel for the chemical industry, A-53 or A-106 seamless, unless otherwise specified. 2.3 Pipe flanges shall be cast ductile iron or forged steel. (Galvanized or stainless special order) All dimensions meet ANSI B 16.42, or B 16.5. 2.3.1 150 Ib. ANSI ductile iron flanges shall conform to ASTM A-395 or A-536. Lap joint or threaded. 2.3.2 150 Ib. and 300lb. ANSI, or higher pressure rated forged steel flanges shall conform to ASTM A-105, Lap joint, threaded or weld type. 2.4 Fittings shall be castings or fabricated steel with applicable flanges, in accordance with paragraph 2.3. 2.4.1 150 Ib. ANSI cast ductile iron fittings shall conform to ASTM A-395 or 536 or be fabricated from schedule 40 carbon steel pipe, using accepted industry processing methods, i.e. cold van stone flaring, bending, welding, etc. Flanges shall be lap joint ductile iron as described in paragraph 2.3.2. 2.4.2 150 Ib. and 300 Ib. ANSI, cast steel fittings shall conform to ASTM A-216 or be fabricated from standard forged steel weld fittings or schedule 40 carborn steel pipe in accordance with ASTM A-234 and accepted industry processing methods, i.e. cold van stone flaring, bending, welding, etc. Flanges shall be forged steel lap joint or weld type as described in paragraph 2.3.3. 2.5 Plastic linings employed in both pipe and fittings shall have the minimum uniform wall thickness shown on page 5. 2.6 All plastic linings must be seamless and homogeneous. 2.6.1 Plastic shall be mechanically swaged into pipe or molded in place only after the fitting or pipe is cast or completely fabricated. 2.6.2 Bending, expanding, thinning or distorting the lining in any way is not permitted. 2.6.3. Flaring or machining of the plastic face is to be performed only after the lining is temperature compensated and stabilized by cycling each pipe spool or fitting from ambient through its temperature range. 3. QUALITY ASSURANCE AND INSPECTION 3.1 All pipe and fittings shall be visually inspected for any imperfections prior to lining. 3.2 Interior of pipe and fittings shall be smooth, clean and free of burrs or other imperfections. All corners in contact with the lining are to be radiused and welds ground smooth. (1/8" R min.) 3.3 All welding operations must be performed prior to lining. 3.4 After lining, all plastic lined pipe and plastic lined fittings must individually pass a minimum of 25,000 volt non-destructive electrostatic spark test. 3.5 That portion of the plastic lining forming the flange gasket sealing surface shall be free of scratches, dents or any defect measuring greater than 10% of the lining thickness. 3.6 After thorough inspection, all plastic lined fittings and plastic lined pipe spools shall have the plastic raised face protected with minimum 1/2" thick plywood end covers. They should not be removed until the plastic lined pipe or plastic lined fitting is ready for installation. If protective covers are removed for inspection, they should be replaced as soon thereafter as possible.
