Clad Plates for Oil & Gas
Explosion clad plates give oil and gas equipment the corrosion resistance of a high alloy at the cost of carbon steel. A thin layer of stainless steel, duplex or nickel alloy is bonded to a pressure-vessel steel base by vacuum explosion welding, so the base carries the pressure and the clad layer resists the process fluid.
Where clad plates are used in oil & gas
- Pressure vessels, separators and drums (onshore and offshore)
- Heat exchanger tube sheets and channel covers
- Sour-service and high-chloride process equipment
- Columns, reactors and storage in refineries
Typical combinations
- Duplex and super duplex on SA516 or HIC-resistant steel
- Alloy 625, 825 and C-276 on carbon steel for sour gas
- 316L stainless on pressure-vessel steel

Why vacuum explosion cladding
- 100% dense, oxide-free bond — no porosity to start corrosion
- 100% automated ultrasonic testing of every plate
- Tested per ASME SA-263 / SA-264 / SA-265 and EN 13445-2, also after simulated PWHT
- Audited by Aramco, Shell and Repsol
- All production steps on one site for short, reliable lead times
Frequently Asked Questions
Why use clad plates instead of solid alloy in oil and gas?
A clad plate uses expensive corrosion-resistant alloy only where it touches the process fluid. The carbon-steel base carries the pressure, which cuts material cost substantially for thick-walled vessels.
Do explosion clad plates survive post-weld heat treatment?
Yes. Shockwave re-tests specimens after simulated PWHT cycles (for example 620 °C for 60–180 minutes) so the bond is proven for your fabrication route.
Which standards apply?
Clad plates are tested per ASME SA-263, SA-264 and SA-265, AD-W8, EN 13445-2 and the project specification.
