SCOPE This specification covers Polytetrafluoroethylene (PTFE) line pipe & Fittings applied for conveying corrosive fluids. The contents include the requirement for construction of materials, dimensions together with standard test procedure.

2 This specification covers ANSI 150lbs & JIS 10K PTFE Lined pipe, flange and Fittings in nominal diameters from 1/2 to 12 . The PTFE Lined flange, pipe and fitting assemblies are limited for use from -28 C to 260 C Temperature limitations are based on non-corrosive test condition, and temperature limitation may be changed by aggressive environment. 2. CONSTRUCTION OF MATERIALS THE PROPERTIES OF PTFE Temperature limitation Maximum continuous service temperature: 260 C Melt point: 327 C Chemical inertness Resist to most of all chemicals.

5 Each pipe will have at least 2 vent holes in diameter (3mm), located 2 (50mm) from the ends. Each fitting shall have two vent holes at least. Reducing flange has no vent hole. Allied Supreme Corp. - 6 - PTFE Lined pipe and Fittings 4. INSPECTION REQUIREMENT HYDROSTATIC PRESSURE TEST The internal test pressure is 150% of maximum recommended working pressure. Reach full test pressure within 1 min. and maintain for 3 min. ELECTROSTATIC TEST Conduct the test with a non-destructive high-voltage tester at an output voltage of 10,000V. A visible or audible spark or both that occurs at the probe when electrical contact is made because of a defect in the liner, shall be cause for rejection. VISUAL INSPECTION, PAINTING INSPECTION All surfaces are free from blister, porosity and other defects. Any defect has to be repaired before shipment. After visual inspection, the external part of pipe, Fittings coated with epoxy primer 1 coat.

6 5. STORAGE, TRANSPORT & IDENTIFICATION STORAGE The faces of each end are protected by wooden plate. So that products are capable of withstanding normal handling during transport. MARKING The markings shall be applied to the pipe, fitting with manufacturers name, order number. TRANSPORT All items are supplied with stout wooden case or export carton depend on the weight, measurement ordered.
