Custom Pressure Vessel Shells

Helander has the ability to fabricate seamless custom pressure vessel shells through a special hot spinning process. Helander can produce a completely seamless pressure vessel (with or without a bottleneck) to meet exact customer specifications using stainless steel, mild steel, aluminum, or other material options.

The maximum dimensional limitations for the tube end closing equipment are a 0.750″ wall thickness (depending on material type), a diameter of 9.625″, and a length of 70″.

If you are interested in welded vessels, Helander can accommodate your specific project needs. Any head that falls under the specifications of the hydroforming or metal spinning capabilities can be formed and then welded to a tube that is either mill purchased or custom made by Helander welding department.

Common Applications: hydraulic accumulators, pneumatic reservoirs, and gas storage.
