Product Q&A
Q:Why are hemispherical heads suitable for high-pressure storage tanks?
A:
Hemispherical structure has uniform stress distribution, no stress concentration. It bears higher pressure than elliptical and dished heads, very safe for high pressure working conditions.
Q:What materials can you produce hemispherical heads with?
A:
We have carbon steel, SS304, SS316L and alloy steel. They are corrosion resistant and suitable for chemical and high temperature environments.
Q:What international standards do your heads follow?
A:
Our products meet GB Chinese standard and ASME international standard, with complete non-destructive inspection reports.
Q:Do you accept customized size and large diameter orders?
A:
Yes, we support customized production according to customer drawings, including extra large split hemispherical heads.
Q:What forming technology do you use?
A:
We adopt cold pressing and cold spinning integral forming. Extra-large diameter hemispherical heads adopt split welding process, with uniform and stable wall thickness.
