Detailed Product Description

flange insulating.

Insulating flanges.

Product Instruction:

Insulated flange is the general term for pipe flange joints meeting both sealing requirement on buried steel pipelines and electrric if a pair of steel flanges,insulated sealing piece between two flanges,flange fasteners and fastener insulation parts as well as a couole of steel stubs welded respectively to the two flanges.

Product Description:

Insulated flanges are mainly applied in fuel gas distribution system,and regulator station and pressure regulating box.It can keep mutual insulation fro, fuel gas doistribution pipe to distribution system and regulator station to protect the fuel gas destribution pipe from electrochemical and also extend pipes service life.As an insuspensable part of a pipe cathodic protection system,this product has the characteristics of free maintenance,strong adaptability and long service life.Because of their economical and practical features,they are absolutely necessary parts for gate stations,storage and distribution stations specified by related national standards.

Product Usage:

This product is used for electrochemical corrosiom preventio and joining of buried steel pipelines in urbon coal gas,natural gas,liquefied petrochemical gas(LPG)and other medium,as well as insulation protection.

Product Features:

1.       Electric insulation of buried steel pipeline electroerosion prevention.

2.       Reliable long-term operation under the temperature and pressure required for pipe-conveying medium and sufficient strength and sealability.

3.       Reasonable structure,easy assembly,disassembling and part replacement.
