Case Study | Nantong Hengli Pressure Vessel Head Manufacturing Co., Ltd. — Spin-Forming Applications for Pressure Vessel Heads

Wuxi Dongyang Spin-Forming Equipment Co., Ltd. provides head spinning machines to Nantong Hengli Pressure Vessel Head Manufacturing Co., Ltd., specializing in the precision manufacturing of pressure vessel heads:

1. The dimensional accuracy of various pressure vessel heads is stable, with smooth arcs and well-formed straight sections, facilitating subsequent cylinder welding and assembly, ensuring uniform and consistent assembly gaps;

2. Spin-forming results in a continuous and dense metal grain structure, giving the heads significantly superior pressure-bearing and explosion-proof performance compared to split-welded structures;

3. The wall-thickness reduction is precisely controllable, consistently meeting the national standard tolerances for pressure vessel head wall thickness, and enabling smooth passage of third-party pressure testing.
