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.

Automate Bending

Panel Bender for Pressure Vessels & Tanks

A HARSLE panel bender clamps the sheet flat and forms all four sides in one cycle with universal tooling — ideal for the repeat panels, doors and boxes found in pressure vessels, tanks & oil and gas.

Bending length 1400–3000 mm (AutoBend)
0–180° bending angle, 0.2 s per bend
Minimal operator skill, fast changeovers

Frequently Asked Questions

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.
