Pressure vessels,chemical equipment

69 years refined technology. Design and fabrication of pressure vessels.

In Chiba head factory, we can fabricate at maximum weight of 60 ton pressure vessels.
Also we can ship oversized equipment from the wharf behind of our factory.

High pressure gas designated equipment (Japan METI)
Power generation equipment (Japan METI)
Gas facilities (Japan METI)
Class-1 pressure vessel (Japan MHLW)
Class-2 pressure vessel (Japan MHLW)

We have acquired much experience of welding procedure for pressure vessels, such as Titanium, Nickel Alloy, Clad steel and Dissimilar-metal.
That is our references verified by 69 years history.
