Lining Processing Specification:
PFA Lined Fittings By Injection Molding
Nominal diameter: DN25~DN300
Temperature range: -29°C~200°C
Applicable medium: Able to transport any concentration of acid, alkali, organic solvents, strong oxidant, toxic and volatile, flammable chemicals
Youfumi 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 antiosmosis.
●PTFE advanced lining molding process achieved the status of syn chronous hot expansion or cold shrinkage for steel components and fluorine plastic.
●Youfumi adopts the standard size according to HG, GB, DIN, ANSI, and JIS etc., which improves interchangeability, to provide convenience for installation.
