Square Welding Bellows

The scope of production depends on customers’ request.

NW (KF) Molded Bellows

The molding bellows are used in various fields such as vacuum, pressure, and fluid transport pipes, and the molding method, shape, material, and thickness of the bone vary depending on the use environment.

In case of vibrating piping, thin materials are used for operation and absorption of vibration as the flexibility and high life of bellows are required, and in case of pressure piping, thick materials are used to increase the capacity of resisting pressure. In addition, in environments where corrosive fluids are used, expensive materials that can withstand corrosion are required.

Braid Molded Bellows

It is the product with improved durability against external breakage or internal pressure by installing an additional braid(net) at ordinary NWs or molded bellows of 1 inch or less.

SUS Seamless Bellows

As the bellows manufactured after drawing a thin plate, tubing it, and molding it, the corrosion resistance and durability have been improved because the existing Bellows' tubing welding process was eliminated.

Bronze Bellows

It causes contraction and expansion according to internal and external pressures, and is widely used in general industrial device and control devices such as air compressor, summer start, pressure switch, pressure gauge, thermal sensor detection, steam control valve, instrumentation control and so on.

Teflon Bellows

It is made by special processing Teflon, a fluororesin. It is used in corrosive gases, strong acids, and chemicals that cannot be used as ordinary metals because it is made of a material that meets the customer's needs and the conditions of use.
Intercompatibility can be maintained as it is manufactured in the same way as a general KF or ISO standard etc.

* The shape and length of Flange are adjustable at the request of the customers.
