DN250 PN16 Flanged Rubber Bellows Connector Epdm Ansi 150lb Rubber Expansion Joint

DN250 PN16 Flange Connector Epdm Ansi 150lb Rubber Expansion Joint

Why is the elasticity of our rubber joints good?

First, the free extension of molecular chains
Rubber is a kind of network polymer material, whose molecular chains are connected by covalent bonds to form the material structure. Under the action of force, the rubber molecular chain can be freely extended and rotated, so that its material shows excellent elastic performance. This is one of the main reasons for the high elasticity of rubber.
Second, a large number of cross-linked structures
Rubber has a large number of cross-linked structures, which can support and limit each other during the process of material stress, thereby increasing the strength and elasticity of the material. In addition, the cross-linked structure can also effectively prevent the sliding and falling off of the molecular chain, so that the rubber still has a good elastic recovery performance after multiple stretches.
Third, the free rotation of molecular chains
Rubber molecular chains have the ability to rotate freely. During the stretching process, the rubber molecular chain will automatically rotate, thus relieving the internal stress caused by the tension. The relief of these internal stresses also provides another important condition for the high elasticity of rubber.

Structural composition

The rubber joint is formed by the inner and outer rubber layer, nylon cord fabric, steel ring, etc., after vulcanization, and then combined with the metal flange or the parallel joint loose sleeve. The product can reduce vibration and noise, and can compensate for thermal expansion and contraction caused by temperature changes. It is widely used in various pipeline systems.
