Pipeline expansion joints can meet various pressure requirements in pipeline systems and are widely used. Due to their rapid closing capability, they can handle a wide range of positive and negative pressures. The maximum positive pressure is 4.0 MPa, and…
Many people have likely heard of underground installation devices for rubber joints. These devices are primarily designed for special geographical environments, effectively protecting acid and alkali-resistant rubber joints from various complex factors. So, what are these complex factors? The main…
Acid and alkali resistant rubber joints are mainly used in pipelines with acid and alkali corrosion. However, they cannot be used in all media containing acid or alkali; there is a limit. For example, in some sewage pipelines, the acid…
Acid and alkali resistant rubber joints are mainly used in corrosive pipelines, providing resistance to acids and alkalis. They are commonly used in sewage and chemical pipelines. These joints are primarily made of EPDM (ethylene propylene diene monomer) raw material,…
To solve the problem of leaks in rubber joints, it’s essential to first understand the cause. If the leak originates in the center of the rubber sphere, it’s likely due to insufficient rubber content or poor rubber quality. If the…
