Industrial pipe dn65 flexible bellows expansion joint screwed union

 

The bellows expansion joint is composed of elastic rubber joint, plane movable joint, loose metal flange or threaded pipe flange, which is used for vibration isolation, noise reduction and displacement compensation. Bellows expansion joint is a kind of pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. The flexible rubber expansion joint is composed of inner rubber, polyester cord reinforcing layer, outer rubber and composite rubber hose. The outer and inner layers of rubber materials can be different. However, the frame layer of bellows expansion joint is made of polyester fabric, and the reinforcing layer has a steel ring.

Note: 1. The special requirements of bellows expansion joint can be customized according to the user's drawing. Flange standard is GB / t9115.1-2000. Various flange standards (GB, JB, Hg, CB, ANSI, DIN, BSEN, NF, en, JIS, ISO, etc.) can be selected for production. The rubber ball of bellows expansion joint can be used as natural rubber, ethylene propylene diene monomer rubber, chloroprene rubber, butyl rubber, butadiene rubber, fluorine rubber, etc. When the bellows expansion joint above DN200 is used for suspended water supply, the pipe must have fixed support or fixed support, otherwise the bellows expansion joint shall be installed with anti falling device.

Bellows expansion joint production Flow

 

Do you know how is a bellows expansion joint made?Let's see with JINGNING.

It is very important to select the appropriate bellows expansion joint of the pipeline, understand the compatibility of the medium with the selected material, the full temperature, pressure and vacuum range, the required movement and the size between the pipeline flanges. With this information, Jingning application engineers can help determine the ideal bellows expansion joint for any application.

 

Bellows expansion joint advantage

 

1. The bellows expansion joint is galvanized for 15 minutes, resistant to high pressure, high temperature, oil, wear, corrosion, acid and alkali.

2. Bellows expansion joint are connected with pumps, valves, fire-fighting equipment, pipes with large vibration and pipes with frequent changes of cold and heat.

3. The natural rubber content of bellows expansion joint is 47%, which can be used continuously for 15 years without aging.

We introduce foreign advanced technology and combine with China's production experience. In the bellows expansion joint manufacturing operation, the inner side bears high pressure, and the nylon cord and the inner side rubber are combined better, which can bear higher pressure than the ordinary bellows expansion joint. Bellows expansion joint is characterized by perfect combination of inner rubber layer, bright, clean and seamless; the label of bellows expansion joint adopts vulcanization process, which perfectly matches the ball of bellows expansion joint.

 

bellows expansion joint application

 

The bellows expansion joint is suitable for connecting the inlet and outlet pipes of all kinds of fan coil units for air conditioning in hotels and other guest rooms. Bellows expansion joints are also suitable for factory and residential plumbing systems, as well as circulating water pipes, sanitary pipes, chemical anti-corrosion and freezing pipes, etc.
