Feature:
1.High reliability: high-frequency heat treatment technology enhances the hardness of the inner layer of the tube (65-67 hrc), and the outer layer has high resistance to plastic deformation.
2.High safety: with the protection of the outer tube, the tube bursting problem of single layer tube due to too deep heat treatment is prevented.
3.High wear resistance: the service life is more than three times longer than single-layer tube, up to 80,000 square meters.
4.High cost performance: saving cost and improving production efficiency.
Application:
Twin wall straight pipe are applicable to high-rise buildings, highways, tunnels, water conservancy projects, nuclear power plants and other construction machinery.widely used in concrete pump truck,steam pump,drag pump,distribution machine and mortar pump.
