Product Description

Prestressed Metal Bellows For Bridge

Prestressed metal bellows are pipe materials made of one or more prestressed steel wires or steel bands wound around the bellows. This material has high stiffness and strength, and has good water pressure resistance and corrosion resistance, so it is widely used in various pipeline fields.


Parameters

Name	Prestressed Metal Bellows
Origin	Jiangxi, China
Diameter	55, 70, 80, 90, 100, 120
Thickness	2, 2.5
Temperature Range	-25~50

Application Range
1. Oil and gas transmission field
Prestressed metal bellows are widely used in the field of oil and natural gas transportation. Its advantages lie in its high strength, stiffness and corrosion resistance, which can meet the requirements of long-distance transportation of high sulfur gases or liquids. In addition, since the inner surface of the prestressed metal bellows is smooth, the sediment cannot adhere, thus reducing the risk of pipe clogging.
2. Heat pipeline field
The fluid temperature and pressure in the thermal pipeline are high, and the environment is harsh, and the traditional pipeline materials are difficult to meet the requirements. Prestressed metal bellows can withstand high temperature and high pressure without deformation, so they are widely used in the field of thermal pipelines. In addition, prestressed metal bellows can also be slightly expanded with temperature changes, so as to effectively alleviate thermal stress.
3. Chemical pipeline field
Prestressed metal bellows are also widely used in the field of chemical pipelines. Due to its excellent corrosion resistance and stress cracking resistance, it can meet the needs of various special working conditions of chemical pipelines, such as high temperature, high pressure, strong acid, strong alkali and so on.



Features
1. Rigorous material selection. Strictly selected low carbon steel made to ensure the construction quality;
2. Not easy to break. The product adopts pipe wall structure design;
3. Bending impermeability test. Filling water or water-cement ratio of 0.5 cement slurry, 30 minutes without leakage;
4. Tensile resistance is not easy to deform. Axial tension 5KN, the pipe wall is not easy to wear and deformation.
