China Hemispherical Head Dished Head
The hemispherical dished head offered by Dingjin General Machinery Co., Ltd. is a pressure vessel component designed for high-stress applications, formed using integral spinning or stamping technology. The supplier’s production range spans diameters from 325 mm up to 10,000 mm with thicknesses from 8 mm to 50 mm via spinning, and up to 6,000 mm diameter with 400 mm thickness via stamping. For multi-petal construction, there is no diameter limit, with maximum thickness reaching 300 mm.
Fabricated from pressure vessel steel plates, these heads meet stringent industrial requirements for strength and uniformity, with typical material grades including SA516-70, SA537, or P355GH, depending on the application. The forming process uses German-made spinning units and dual-action hydraulic presses, including 16,000-ton and 8,000-ton models, ensuring consistent geometry and metallurgical integrity. Surface finish and dimensional tolerances adhere to ASME, DIN, or GB standards, typical for pressure vessel components.
These hemispherical heads are primarily used in chemical, petrochemical, and power generation industries for tanks, boilers, and reactors. Buyers typically source them for projects requiring high-pressure resistance and uniform stress distribution. The supplier’s facility in Dalian, Liaoning, supports bulk orders with custom sizing and OEM/ODM options, while lead times and Incoterms are confirmed directly with Dingjin General Machinery Co., Ltd.
