Understand the secret of steel pipe size error
In the process of manufacturing and using steel pipes, thickness control is an important link. The allowable deviation value of steel pipe thickness is stipulated in relevant national standards. According to different uses and manufacturing processes, the allowable deviation value of steel pipe thickness may be different.
Many people may not know about the error range of steel pipe length. In fact, this is a standard clearly stipulated by the state. In the national standard 3091, the allowable deviation of the total length of straight seam high frequency welded steel pipe is 0 mm-15 mm. The allowable deviation of the total length of submerged arc welded steel pipe is 0mm-50mm, and the cut margin of 5mm-15mm should be reserved for each double length. In this respect, Huayang has always strictly abided by state regulations.
Huayang's cutting unit can chamfer the two ends of the whole production line. The range of blunt edge is 1.6mm plus or minus 0.8mm, and the included angle of groove is between 30 and 50 degrees.
Generally speaking, it is of great significance for the production, use and quality control of steel pipes to understand and master the allowable deviation value of steel pipe thickness and the calculation method of thickness.
So much for the allowable deviation value of steel pipe thickness. For more information, you can pay attention to Hebei Huayang Steel Pipe Co., Ltd.
