PTFE Lined Pipe and Fitting

  All the products are with standard dimensions, especially the pipe and pipe fittings used in chemical pipelines are of great interchangeability, which provides great convenience for installation and maintenance. The main products are spool, elbow, tee, cross, adjustable ring etc more than 1000 specifications.

Lining Processing Specification:

PTFE Lined Pipe by Ram Extrusion:PTFE lined pipes with shortest lengths are around 100 mm. depending upon nominal bore and the longest lengths is 6 meters for up to DN150 and 3 meters above this. Generally constructed from carbon steel pipe, and stainless steel is also popular for dangerous access area where there is the potential for external corrosion.

Product parameter:

Lining Material PFA, PTFE

Nominal diameter: DN25~DN300,1"~12"

Length: ≤6000mm (size≤DN150) ≤4000mm (size>DN150)

Temperature range: -29°C~180°C

Applicable medium: Able to transport any concentration of acid, alkali, organic solvents, strong oxidant, toxic and volatile, 

Specification Instruction:

Manufactures lined pipe and fittings by compression molding, isostatic molding, injection molding, transfer molding, hot rotomolding, ram/paste extrusion, 3D rotational molding etc. Characters as below:   

Working temperature is high at the range of -29°C-200°C; except the molten alkali metals, element fluorine and aromatic hydrocarbon, lined products can be used in any chemical medium. Vacuum resistance In the range of -29°C-150°C, it is applicable for vacuum condition. In chemical production, the vacuum condition occurs due to cooling, longitudinal emissions, or medium backflow. High-pressure resistance Within temperature working condition, it can sustain the working pressure of 3.0MPa. Resistance to penetration  Adapt the high-quality PTFE, to make it of high density and enough thickness after advanced lining processing, make it excellent anti-osmosis. PTFE advanced lining molding process achieved the status of syn chronous hot expansion or cold shrinkage for steel components and fluorine plastic. The standard size according to HG, GB, DIN, ANSI, and JIS etc., which improves interchangeability, to provide convenience for installation.
