Set up in 1995, Tonglu Valves Manufactring Co.,Ltd. is one of the leading China pipe bending manufacturer and supplier in Yongjia County of Zhejiang Province. We manufacture all products strictly conforming to the API, JIS, ANSI, BS, GB, NF and DIN standards. Our oem pipe bendings are available to users on request and are used for municipal works, petroleum, chemical industry, power station, metallurgy, national defense, and scientific research fields.

Native American Technologies has current capabilities of forming tubes and pipes using a 4kW direct diode laser. Although having all of the thermal forming advantages, this method does not meet production speed specifications. We are developing the capability to use this technology with a 25kW induction heating coil which would signify a large decrease in forming time.
Easily forms complex 3D shapes and bends
Does not stretch out pipe thickness, eliminating overall pipe size and weight
Ideal for custom shapes and sizes, no specialty tooling required
CAD to part feasibility
