PO lined high performance pipe and fittings by hot rotomolding
Specification Instruction:
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 anti-osmosis.
PTFE advanced lining molding process achieved the status of synchronous 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.
Specific gravity:
2.14-2.19g/cm3 as per ASTM D 792 test standard.
Tensile rate:
20.7Mpa minimum as per ASTM D 638 test standard
Elongation rate:
250% minimum as per ASTM D 638 test standard.
Manufacture standard:
ASTM D 4895. Operating in vacuum condition within 150°C.
Inspection and Test:
The final inspection of the finished products occurs in several ways. First of all by visual control as to clean and good surfaces and subsequently by dimensional control of length, flange face, threads, check of marking etc. Finally a pressure and tightness test according to the shape and dimension is carried out. Special checks in warm water bath with outside pressure or vacuum checks under raised temperatures are possible. 100% of all parts are checked at room temperature.
Spark testing is an important test for lined pipe and fittings and it is subjected to an electrostatic spark test at 10-20KV to ensure the integrity of the liner.
