Product Q&A

Q:What materials and head types can your factory produce?

We can manufacture heads in carbon steel, stainless steel, alloy steel, aluminum alloy, and titanium alloy. We cover all standard types including elliptical, dished, hemispherical, flat bottom, and conical heads, and can customize them according to GB, ASME, or EN standards.

Q:What is the maximum diameter and thickness you can produce?

We can produce extra-large heads with a maximum diameter of 8000mm and a maximum thickness of 200mm, which fully meets the demands of high-pressure vessels, boilers, and other extreme working conditions.

Q:Can you provide material certificates and inspection reports?

Yes. Every batch of products comes with complete Material Test Certificates (MTC), UT/PT non-destructive testing reports, and hydrostatic test reports, which fully comply with export inspection and EU/US market requirements.

Q:Do you accept small trial orders? What's the MOQ?

We fully support small trial orders. The minimum order quantity (MOQ) is 1 piece, which allows you to test product quality and compatibility before placing large bulk orders at more competitive prices.

Q:What are the installation methods for the hemispherical head?

There are two common installation methods: direct welding and flange connection. Direct welding offers good sealing and low cost for closed vessels. Flange connection allows for disassembly and is suitable for equipment requiring regular maintenance and inspection.
