Chemical resistance: +++ universal

 

advantages-PTFE lined eccentric reducers » almost universal chemical resistance» free from extractable agents» physiologically safe» non-adhesive surface» very good sliding characteristics» very good dielectric characteristics» resistant to irradiation and weather

 

PTFE lined pipes and fitting seriesFeatures:Professional, learning from experiences on dozens of big projects all over the countryfor decades.Having experience and capability on manufacture of supporting componentsaccording to various standards in America, Europe, Japan, Middle East, India andSouth America etc.Supplying supporting components to semiconductor, pharmaceutical products,chemical industry, textiles, automobile coatings and environmental protection and soon for years.Developing matching service on the production of ETFE, F46, PFA and PVDF andother products.

Specification of lined pipes and fittings

PTFE lined pipes

1. Range1.1 This specification is applicable for PTFE lined pipes and fittings used fortransmitting corrosive fluid. The content includes construction materials, size and testprocedure of standards.1.2 The content includes national standard 10KG level, ANSI150LBS and JIS10Kspecification etc.2. Material Structure2.1 PTFE properties2.1.1 Temperature limitationContinuous operating temperature 260°CMelting point 327°C2.1.2 Chemical resistanceResist most of chemicals. For detail information, please consult our sales engineer.2.1.3 Frictional coefficientStatic friction coefficient 0.10Dynamic friction coefficient 0.052.1.4 Proportion ASTM D792 2.14 ~ 2.22.1.5 Tensile strength ASTM D638 280 ~ 350Kg/cm²2.1.6 Anti-adhesiveSurface tension 18.5dyne/cnContact angleWater 104°~ 111°Hexadecane 37°~ 45°2.1.7 Elongation ASTM D638 100-300%2.1.8 Water absorption ASTM D570 0.01%2.2 PTFE liner2.2.1 Sizes of this type of PTFE lined pipes, flanges and fittings are from 1/2" to 12".2.3 Iron parts2.3.1 Pipes and fittingsPipes and fittings are made of welded or seamless steel pipes of iron parts. And the thickness is decided by international standards and customers’ requirements.2.3.2 FlangeFlanges are made according to any specification of international standard orANSI150LBS or JIS10K.3. Design Requirements3.1 Size3.1.1 Standard thickness of PTFE lined pipes Unit: mm

 

Note: for thickness of other PTFE lined pipes different from above and PFA linedpipes below 4", please refer to our sales engineer.3.1.2 Thickness of PTFE lined pipesSize 1/2"~ 4" Thickness of liner 3mm6"~ 8" 4mm10"~ 12" 5mm

3.1.3 Specification of size of lined flaring Unit: mm

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

PTFE lined pipes 4. Detection requirements4.1 Hydraulic testInterior pressure test will be operated at 150% of maximum work pressure. Totalpressure can be reached within one minute and kept for 3 minutes.4.2 Pinhole testThe test shall be performed with high voltage equipment (10,000 V) that shall not bedestructive. After the current is connected, if any spark is produced from the probe orany pinhole warming sound is made by the detector, it means there is defect in theliner and thereby this part shall not pass quality inspection.4.3 Visual inspection and appearance paint brushThe surface shall not have any bubble, pinhole or other defects. All defects shall befixed before shipment. After visual inspection, an epoxy resin base coat shall becoated outside the pipes and fittings.

5. Storage, transportation and confirmationUse wooden plate to protect lining face of flanges at each end. Therefore products willnot be damaged during normal transportation.

end. Therefore products will not be damaged during normal transportation.
