短热带负差生产焊管的措施

MEASURES TAKENFOR PRODUCTION OF WELDED PIPES WITH SHORT HOT-ROLLED STRIP ON A BASIS OF MINUS TOLERANCE

介绍了用短热带按负偏差生产焊管的主要技术措施，指出在生产热带时严格控制热带的厚度在标准要求的负偏差范围内波动；生产焊管时应尽可能提高焊管的定尺率，以达到提高焊管技术指标、为企业创造经济效益的目的。

Introduced in the paper are the main technical measures taken to produce welded pipes with short hot-rolled strip on a basis of minus tolerance.It is emphasized that when producing hotrolled strip steel,any gauge deviation must be well controlled within the minus limit of the tolerance as specified in relevant specification for the product and that for welded pipe production,rate of specific-length products should be as high as possible so as to fulfill the technical norm as required to bring the producer satisfactary economy.
