Welding type direct terminal joint, pressure pad welding joint

Welded pipe joint

Welded pipe joints are suitable for non corrosive or corrosive media such as oil, water, and gas The specification requirements for welded sealed pipe joints and welded hydraulic joints with steel pipes are relatively flexible. After welding with pipelines, they have the characteristics of reliable connection and good sealing performance. Therefore, welded hydraulic joints are widely used in refining, chemical, light industry, textile, metallurgy, shipbuilding and other systems; Welded hydraulic joints are also suitable for various mechanical engineering, machine tool equipment and other hydraulic transmission pipelines. When the production of sleeve type pipe joints cannot meet the needs, and in situations with strong corrosion, welded hydraulic joints can be given priority consideration.

Manufacturing standard for welded pipe joints
