焊管深加工产品及其工艺技术

焊接钢管经冷拔或冷轧等深加工工艺处理后。得到了尺寸公差小，机械性能好的优质钢管，称作DOM钢管，近年来，随着焊管生产工艺的焊管深加工产品的品质，使得其应用领域不断扩大，受到了机械制造和各类高精度钢管用户的青睐。分析预测，该钢管在汽车用管，高压抽油泵管，高速托辊用管。纺织机用牵伸管等应用领域有较好的开发前景，介绍了几种DOM钢管的制造工艺。

Deeply Processed Welded Pipe and Its Procedure

Welded pipe having been deeply processed in deep machining procedure such as cool-draw,cool-rolled,welded pipe will be changed into high quality pipe called DOM pipe with small dimension tolerance and good mechanical properties.With the improvement of the weld procedure and stable and reliable quality of welded pipe in recent years,welded pipe can be used as pipe blank of DOM pipes.This way can ensure the quality of DOM pipe and also draws the attention of customers who need high precise pipe.After analyzed,prediction is made that DOM pipe owns bright exploration prospect in automobile,high pressure pump pipe,high speed roller pipe,draught pipe in weave machine etc..Some manufacturing procedure of DOM pipe is introduced.
