How to repair the surface defects of Honed tube

1.Increase the amount of cold-drawn deformation

Increasing the number of cold-drawn deformation and increasing the total deformation can achieve the purpose of reducing the depth of the hemp point and reducing the honing grinding allowance.

2.Preferred hot-rolled tube blanks

Cold-drawn pipe defects are caused by hot-rolled pipe, so, through the selection of small corrosion degree, uniform wall thickness of the hot-rolled pipe, can reduce the defects of the hemp, improve the yield of the cylinder.

3.Hot-rolled pipe hole defect cleaning
