Welded expansion joints

Welding and disassembling expansion joints, welding expansion joints, expansion joints, as the name suggests, 

is a kind of connection device that can be stretched freely within a certain range.

It connects two sections of pipes or components closely by welding.

At the same time, it can adapt to the axial displacement caused by temperature changes, pressure fluctuations and other factors.

This design not only guarantees the robustness of the connection, but also greatly increases the flexibility and durability of the system.

In the welding process, the selection of materials, design and welding process of expansion joints are crucial.

High-quality materials can ensure the strength and toughness of the joint,

Reasonable design can make it maintain good performance in various working conditions.

Exquisite welding technology is the key to achieving all this.

Expansion joints are widely used in petroleum, chemical, electric power, metallurgy and other industrial fields.

Especially in the pipeline system, its unique expansion and contraction function can effectively alleviate the stress concentration

 caused by thermal expansion and cold contraction.

This extends the service life of the pipeline and reduces maintenance costs.
