PFA/PTFE/FEP lined Pipe and fitting for chemical mediums
« on: May 02, 2018, 11:50:43 PM »
FUVALVE 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 to 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 resisitance.Within temperature working condition, it can sustain the working pressure of 3.0MPa.

Resistance to penetration.Adapt the high-quality PTFE,PFA,FEP to make it of high denstiy and enough thickness after advanced lining processing,make it excellent anti-osmosis.

PTFE advance lining molding process achieved the status of synchronous hot expansion or cold shrinkage for steel components and fluorine plastic.

FUVALVE adopts the standard size according to HG,GB,DIN,ANSI, and JIS etc., which improves interchangeablity,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 D638 test standard.

Elongation rate:
250% minimum as per ASTM D638 test standard.

Manufacture standard:
ASTM D 4895. Operating in vacuum condition whitin 150°C.

Fluorine lined Pipe and fitting for chemical liquids

In corrosion resistance materials,fluorine has its super nice performance.it can not only dissolved to alkaline metal, F1uorine, aromatic hydrocarbons but also follow with other’s natural response while meet HCL, H2SO,, aqua regia, organic acid, strong oxidant, alternate thick and thin acid, alkali. Sticking fluorine inside valve’s body, it can conquer the fluorine’s problem of low intensity, furthermore, it solved the problem of the body material in high cost but poor corrosion resistance. In addition, except the stable chemical specification, fluorine has its other merit such as antifouling, sticky- safe, low friction coefficient.

With the speedy development of industry, fluorine lined valves will widely used in petroleum, printing, chemical industry and so on with its Vigorous vitality. As a first choice for project, more and more attention takes by design institutes and construct institutes to this strong market potential product fluorine lined valves.

We center on the field of fluorine lined valves for so many years, after wide market diagnoses and throgh the unceasing efforts of the technicians, 8 kinds of the products with unique form have been researched and developed, such as fluorine lined cock valve, butterfly valve, ball valve, globe valve, check valve,daiphragm valve, gate valve and so on, with 10 pressure classes and more than 1 120 specifications Except the liningof PTFE ( F4)、 RPTFE (RF4)、FEP (F46)、PFA, PVDF,we add PO, PE, PP and PVC to cater to different using demand.

Our staffs always takes “orient by market , develop by technology, ” as the guide lines, making more efforts and researches constantly to return our customer by better and better corrosion resistance valves.
