The main feature is the shape of the insulating joint compact , high integrity, can be buried , maintenance , insulation resistance , good insulation effect, the product has a strong internal discharge recovery device in order to avoid product suffered in the course of lightning and electrostatic electrical insulation failure caused by agglomeration is insulated joints upgrading of products. The main technical indicators have reached Germany with the industry standards of quality and technology .

Insulating fittings for natural gas, liquefied petroleum gas , oil , refined oil, artificial gas , chemical industry , water conservancy and water in different sectors of buried metal pipes, for a variety of soil conditions. Urban buried low metal pipe , oil pipelines and long distance metal buried pipeline cathodic protection system is particularly applicable .

 

1 , insulation joints before installation, and respond to its appearance insulation resistance test

2 , insulated butt connectors direct connection with the pipe shall not change its length geometries.

3, insulated joints and pipe welding , the weld site of filming , the metal pipes with insulation joints exposed part polished metallic luster , and the outer coating treatment immediately.
