Product Introduction

Screw Thread Rubber Joint

JGD-B screw thread rubber joint, also known as flexible joint, rubber expansion joint, rubber flexible joint, pipe expansion joint, soft rubber joint etc.

 

We introduce advanced technology from abroad, and combine it with Chinese production experience. In the manufacturing operation, the inner side endures high pressure; nylon cord fabrics and the inner rubber are better combined and can work under higher pressure than normal flexible rubber joint. Its characteristics are that the inner adhesive layer united perfectly, bright, clean and seamless; the tag adopts the vulcanization process, perfectly matches the product.


Screw thread rubber joint is the soft joint of metal pipes, and consists of inner rubber, nylon cord fabric, outer rubber compound rubber ball and metal lap joint flanges. The product can endure high pressure, maintain good elasticity, have large displacement to balance pipe deviation, absorb vibration and make less noise and have easy installation, etc.

 

Screw thread rubber joint can be widely used in the pipe system of water supply, drainage, circulating water, HVAC, fire protection, paper making, pharmacy, petroleum chemical industry, ship piping system, water pump, compressor and fan etc. The normal type is used to transport air ranges from - 15 to 115 , compressed air, water, sea water, oil, acid and alkali etc. The special type is used to  transport the media above ranges from - 30 to 250 above, oil or strong alkali, strong acid and solid material.
