Overview

First, the metal bellows expansion joint uses PTFE powder to press it into the pipe, chemically treat the surface, and then line it into a seamless steel pipe.

1.5-2mm) to form a seamless lining. In order to reduce the pressure, it needs to be placed in a furnace and heated to 180 degrees to maintain a constant high temperature treatment so that it can be used at temperatures below 180 degrees. At the same time, the strength of the axially stretched and extruded (extruded) pipe is significantly better than that of the wound pipe, and can be used for slight negative pressure pipes.

Features and advantage

1. Lining material: PTFE, PFA, FEP, PVDF, PO, PP, PE

2. Under 1.5 times of the design pressure, the pipes and pipe fittings are tested for hydraulic pressure

3. In the case of PTFE lining, a 100% integrity test is performed after the hydrostatic pressure test, and the test method for the leakage point is the electric spark test.
