Pressure Vessels & Tanks Basics

How Pressure Vessels, Tanks & Oil and Gas Are Made

Pressure vessels and tanks are made from carbon steel, stainless steel and alloy plate, typically 6–100 mm thick, while drums and containers use thinner sheet. Plates are cut, rolled into cylindrical and conical shells on plate rolling machines, heads are pressed or spun, nozzles and saddles are formed on presses and press brakes, and everything is welded to code.

Roundness, accurate pre-bent ends and repeatable heads are critical because they determine weld fit-up and inspection results.

Challenges & Solutions

What Matters in Pressure Vessels & Tanks

  • Roundness & fit-up

    CNC 4-roll machines pre-bend both ends so longitudinal seams close without flat spots.

  • Thick, high-strength plate

    Heavy rolling capacity and hydraulic presses handle thick alloy plate.

  • Code compliance

    Repeatable forming supports consistent weld preparation and inspection.

  • Container volumes

    Deep-drawing presses produce drums and cans efficiently.

HARSLE AutoBend panel bender

Common questions about machines and processes for pressure vessels, tanks & oil and gas.

Ask our engineers

Which rolling machine is best for pressure vessel shells?

A CNC 4-roll plate rolling machine pre-bends both plate ends in one setup and repeats the radius accurately, which gives better roundness and seam fit-up on thick plate.

How are vessel heads made?

Dished and flanged heads are pressed on large hydraulic presses or spun and flanged on dedicated machines, then trimmed and beveled for welding.

How are metal drums and containers formed?

Drum bodies are rolled and seam-welded or deep drawn on hydraulic presses; ends are pressed and joined by seaming or welding.

What thickness can HARSLE rolling machines handle?

HARSLE QuadRoll 4-roll machines handle plates up to about 200 mm depending on width and material.
