high pressure clamp connector and valve without welding  

• The picture above is self-energized flange connecting with valve without welding.
• Flange can connect valve without welding and no leackage. We have both national patents for high pressure self-energized flange and flange with valve.

clamp connector, also called pipe connector or high pressure self-energized connector. 

clamp connector is made of 4 parts:

• 1. Two HUBS, which weld with the pipe and its material is the same with pipe.
• 2. One seal ring, which can be carbon steel and stainless steel. We chose the material according to the working condition. It can be used again and again.
• 3. A pair of clamp, which surround the hub and seal ring, and it has enough strenth to keep it safe.
• 4.  Four sets of spherical bolts and nuts.

high pressure clamp connectors Working condition and working field:

• Size: DN15-DN600
• Pressure: <150MPA
• Tempreture: <500℃
• medium in the pipe: can be gas,  crude oil with corrosion and washing out.  

high pressure clamp connectors Life span: 10-20 years.

high pressure clamp connectors' Advantages Compared with tranditional flange:

• low weight (it is only 1/3 of the tranditional flange for the same size.);
• easy installation and disassembly;
• long life time;
• no leackage.
