PTFE Lined Sight Glass Flange Straight Pipe with ASTMF 1545, HG/T 21562 Standards
PTFE lined pipe by ram extrusion:
PTFE lined pipes with shortest lengths are around 100mm 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 description:
1. Youfumi manufactures lined pipe and fittings by use compression molding, isostatic molding, injection molding, transfer molding, hot rotomolding, ram/paste extrusion, 3D rotational molding etc. Characters as below:
2. Working temperature is high at the range of -29oC-200oC; except the molten alkali metals, element fluorine and aromatic hydrocarbon, lined products can be used in any chemical medium.
3. Vacuum resistance. In the range of -29oC-150oC, it is applicable for vacuum condition. In chemical production, the vacuum condition occurs due to cooling, longitudinal emissions, or medium backflow.
4. High-pressure resistance. Within temperature working condition, it can sustain the working pressure of 3.0MPa.
5. 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.
6. PTFE advanced lining molding process achieved the status of synchronous hot expansion or cold shrinkage for steel components and fluorine plastic.
7. Youfumi adopts the standard size according to HG, GB, DIN, ANSI, and JIS etc., which improves interchangeability, to provide convenience for installation.
8. Specific gravity: 2.14-2.19g/cm3 as per ASTM D 792 test standard.
9. Tensile rate: 20.7Mpa minimum as per ASTM D 638 test standard
10. Elongation rate: 250% minimum as per ASTM D 638 test standard.
11. Manufacture standard: ASTM D 4895. Operating in vacuum condition within 150oC.
