Structural features of fully welded ball valves:

Valve overall structure

By welding forged steel, the forged material needs to undergo ultrasonic inspection in accordance with ASME non-destructive testing requirements. Liquid penetration inspection is required for the welding corners of the connecting surface.

Corrosion resistance and sulfide stress resistance

The thickness of the valve wall has reserved some corrosion allowance. The carbon steel valve stem, fixed shaft, ball, valve seat, and valve seat ring have all been chemically plated with nickel in accordance with ASTM B733 and B656. In addition, various anti-corrosion materials are also provided for users to choose from.

Welding of large and small head connections

When producing fully welded pipeline ball valves, the large and small end connections can be welded onto the welding end valve. Users can provide their own connectors, or our company can provide them according to user requirements. When placing an order, please indicate the diameter and length A of the connecting pipe for the large and small ends.
