Product Features
Honed tube adopts advanced technologies such as cold drawing and turning to ensure excellent dimensional accuracy and surface smoothness. Cold drawn tube is a type of pipe made through the cold drawing process, which has high dimensional accuracy and surface smoothness. The cold drawn seamless pre honed tube is further pre honed on the basis of the cold drawing process to meet high-precision requirements.
