Industrial Insight

Mastering the Art of Tank Manufacturing

Pressure vessel fabrication is a critical manufacturing process requiring extreme precision. It involves transforming flat metal sheets into cylindrical or spherical containers designed to hold gases or liquids at high pressures.

The quality of a pressure vessel depends heavily on the integrity of the longitudinal and circumferential welds, as well as the geometric accuracy of the rolling process.

  • Material Versatility: Handling Carbon Steel, Stainless Steel (304/316), and Aluminum.
  • High Precision: Rolling tolerances within millimeters for perfect welding fit-up.
  • Automated Efficiency: Replacing manual welding with automated seam welders for 100% X-ray pass rates.
1

Plate Rolling

Heavy-duty hydraulic rolling machines curve metal plates into precise cylindrical shells.

2

Longitudinal Welding

Automatic seam welders (TIG/MIG/Plasma) join the rolled edges to form a sealed cylinder.

3

Assembly & Cir-Welding

Fitting end caps (heads) and welding the circumferential seams with rotators.

4

Polishing & Finishing

Automated polishing for sanitary (food/pharma) or industrial applications.

Frequently Asked Questions

Common questions about pressure vessel manufacturing lines.

Can you provide a full production line for LPG/LNG tanks?
Yes. We specialize in integrated solutions including decoiling, plate cutting, edge milling, rolling, longitudinal welding, head assembly, circumferential welding, and final testing equipment. We can design the layout based on your factory space.
What welding methods do your machines support?
Our automated welding manipulators and column & booms support TIG (GTAW), MIG/MAG (GMAW), SAW (Submerged Arc Welding), and Plasma welding (PAW). We select the power source (e.g., Lincoln, Miller, or top Chinese brands) based on your budget and technical requirements.
Do you offer installation and training services?
Absolutely. As a global exporter, we send engineers to customer sites (or provide online guidance) for installation, commissioning, and operator training to ensure your team can operate the machinery safely and efficiently.
