摘　　要：生产抗挤套管的关键在于尽量降低管体残余应力。除了采用热矫直工艺可以明显降低残余应力外,提高管体几何尺寸精度也可以大幅度降低管体残余应力。阿塞尔三辊轧管机组不但可以保证管体高的几何尺寸精度,同时由于采用斜轧所形成的﹛111﹜织构可以有效提高管体抗挤强度。It is very critical for manufacturing the anti-collapse casing to minimize the residual stress of the pipe body.Such residual stress of the pipe body can be considerably reduced by both employment of the hot-straightening process and improvement of the dimensional accuracy of the pipe itself.The Assel mill can not only ensure higher dimensional accuracy of the pipe, but also enhance the anti-collapse performance of the pipe due to its ﹛111﹜ texture as resulting from the cross-rolling process.
