The main quality control of manufacturing for pressure vessel shells and head ends

The main quality control of manufacturing for pressure vessel shells and head ends(including spherical, inner shell of multilayer pressure vessels )

1. The geometry shape of groove and quality of surface

2. The straightness, angularity, the align deviation value of welding seam of both longitudinal and circumferential, diameter difference of maximum and minimum of the same section

3. The loosening area of the multi-layer wrapping pressure vessel and the gap of the nesting surface of the nesting pressure vessel

4. Splice forming of head and deviation of main dimension

5. Dimensional deviation and surface quality of spherical shells

6. Requirements for butt joint connection of cylinder and head with different thickness

As a pressure vessel and heat exchanger manufacturer, we also produce flange for pressure vessel with high quality and competitive price.
