Quality assurance of forgings uesd for pressure vessels

Forgings are widely used in many fields. Several forging parts are needed in pressure vessels. Play an important role in this.

We from raw materials, forging, heat treatment, machining, quality inspection, four links to explain.

1,The raw materials

The material of heavy forgings for pressure vessels is low alloy steel. Steel for pressure vessels has strict requirements on chemical composition.

Chemical elements to be in accordance with customer requirements. C, Mn, Ni, Mo, Si, S, P, Cu, etc. Lab results, make sure they match.

2,Forging

The top cover is an integral forging. This has higher requirements for forging forming control, tooling design and manufacturing, hardware facilities (press, operator, driving, etc.). The forging factory should have high forging technology and rich forging experience.

3,Heat treatment

It is necessary to accurately control the temperature and time. Heat treatment furnace according to the performance of the forging. It's all controlled by computers. Make test bar and test performance.

4,Machining

Use machining centers to produce according to drawing dimensions and tolerances. Every dimension should meet the requirements.

5,The quality inspection

Raw material test, forging size test, UT test, bar test, size test, hydrostatic test.
