2.3.2 Flange
Flanges are made according to any specification of international standard or
ANSI150LBS or JIS10K.
3. Design Requirements
3.1 Size
3.1.1 Standard thickness of PTFE lined pipes Unit: mm

Note: for thickness of other PTFE lined pipes different from above and PFA lined
pipes below 4", please refer to our sales engineer.
3.1.2 Thickness of PTFE lined pipes
Size 1/2"~ 4" Thickness of liner 3mm
6"~ 8" 4mm
10"~ 12" 5mm

3.1.3 Specification of size of lined flaring Unit: mm

3.2 Vent holes
Every pipe or fitting is equipped with vent holes to release gas between liners and iron
parts. Each pipe shall at least have two vent holes of 0.12"(3mm)in diameter, located
at flange faces of two ends, 2"(50mm); each fitting shall also at least have two vent
holes; and reducing flange does not have any vent hole.

4. Detection requirements
4.1 Hydraulic test
Interior pressure test will be operated at 150% of maximum work pressure. Total
pressure can be reached within one minute and kept for 3 minutes.
4.2 Pinhole test
The test shall be performed with high voltage equipment (10,000 V) that shall not be
destructive. After the current is connected, if any spark is produced from the probe or
any pinhole warming sound is made by the detector, it means there is defect in the
liner and thereby this part shall not pass quality inspection.
4.3 Visual inspection and appearance paint brush
The surface shall not have any bubble, pinhole or other defects. All defects shall be
fixed before shipment. After visual inspection, an epoxy resin base coat shall be
coated outside the pipes and fittings.

5. Storage, transportation and confirmation
Use wooden plate to protect lining face of flanges at each end. Therefore products will
not be damaged during normal transportation.
