PTFE LINED PIPE BY isobaric molding

Lining process description:
the production efficiency is relatively low, and the inner surface of the product can be smooth, dust-free, and meets the requirements of food grade and pharmaceutical grade pipeline applications.
Product parameters:
Nominal diameter: DN25~DN1000, 1″~39″
Production length: ≤5000mm
Applicable temperature: -29 ° C ~ 180 ° C
Applicable medium: It can be used in the temperature range of -29°C~180°C, under full vacuum condition, in any corrosive medium pipeline.
Feature Description:
Since the introduction and research of the overall molded PTFE lining technology in 2007, the company has successfully developed overall molding, isostatic pressing, injection molding, transfer molding, extrusion, Three-dimensional rotating and other lining molding products, the characteristics are as follows:
●The use temperature is high. In the case of strong corrosive media, it can be used in the temperature range of -29 ° C ~ 200 ° C, in this temperature range (except molten alkali metal, elemental fluorine and aromatic hydrocarbons), to meet all chemical media.
●Resistant to vacuum. In the range of -29 ° C ~ 150 ° C, can be used under vacuum conditions, in chemical production, often due to cooling, longitudinal discharge, pump and valve asynchronous operation, etc. caused by the local medium backflow to create a vacuum state.
● High pressure resistance. It can withstand a service pressure of up to 3.0 MPa in the temperature range.
● Resistance to penetration. The high-quality imported PTFE resin is processed into a high-density, sufficient-thickness PTFE lining layer through advanced lining process, which makes the product superior in permeability resistance.
● The overall PTFE molding and sintering process lining solves the problem of steel-fluorine cold heat expansion and contraction, so that it can achieve synchronous expansion and contraction.
The product design conforms to domestic and international standards such as HG, GB, DIN, ANSI, JIS.
Specific gravity: 2.14-2.19g/cm3 According to ASTM D 792 test standard.
