Expanding machine for improving the quality of a pipe crucial technical equipment, it is increasingly being used in pipe production, especially for LSAW pipe, expanding machine is indispensable equipment. My company has two HME and UOE LSAW pipe production line, in order to meet the user's various choices, expanding machine equipped with hydraulic and mechanical expanding machine.

Straight seam submerged arc welded pipe forming method mainly UO, RB, JCO, C and Hu-Metal and other five, while the use of these five molding method of steel production, but there are varying degrees of geometry accuracy is not high . Because of LSAW pipe seam in one side of the body inside and outside welding, pipe and thus under the influence of thermal stress to bending deformation and longitudinal shrinkage of the weld area is large, so that the flatness of the steel pipe serious affected, in addition, the production of these five pipe forming method, there is a greater ovality problem, especially steel JCO and C after forming. Therefore, it must be through expanding mill sizing, shaping, thereby improving the dimensional accuracy of steel.
