Stainless pipes

We have been manufacturing stainless steel pipes since 1968, and have received high praise from customers as a Sankin pipe manufacturer.
Highly functional products with excellent workability, manufactured using laser welding and the latest pipe manufacturing equipment, are highly valued and adopted.
TIG products are also used for their small diameter, multi-product, small lot, and short delivery times.

Excellent workability
Laser welding achieves amazing pipe expansion resistance and excellent pipe plastic workability by controlling the HAZ of the welded part to a small level.

High precision finishing
We have the latest pipe manufacturing line equipment and utilize optimal mold adjustment to achieve excellent outside diameter dimensional accuracy.

Multiple steel types
Laser welding is ideal for making ferritic stainless steel pipes, and we can propose a variety of steel types to suit your specifications and applications.
