In this article, it explored the current status and existing problems of reshaping& straightening technology for steel pipe. Combined with reshaping&straightening technology and equipment characteristics, the optimized design was carried out on the mould of steel pipe reshaping & straightening machine, it realized the objective of reshaping & straightening for the steel pipe which pipe diameter is not more than φ762 mm. For the steel pipe with diameter more than φ762 mm, during straightening process, the pipe wall is easily flattened, so the reshaping & straightening technology for straightness exceeding standard will be continuously researched.
