1. There is 5-10mm telescopic adjustment between socket and flange end.

The pipe can be cut into different lengths, and pipe connection is changed from a socket pipe to a flange connecting pipe.

Install easily and quickly. Using only one torque wrench to tighten high strength bolted connection.

2. Wide range of different pipe OD with +/- 6° deviation.

It can be used in the large bending radius pipeline and allowable for the normal movement of the pipe such as ground subsidence.

3. The simplicity and versatility of this product make them suitable for many applications including pumping stations, water purification plants, sewage treatment plants, plat rooms, instrument rooms, power generation equipment, gas stations and all pipelines.

4. Product design and manufacture according to BS, EN, ISO9001:2008 system and surface anti-corrosion material through the most stringent WRAS certification, so it can be used for drinking water.

5. We provide EPDM, NBR, SBR rubber pad and carbon steel/stainless steel bolts for long term rust protection.

Because this product can be connected to different pipe diameter pipeline, it can reduce your investment in the inventory.
