ASTM A135 GR.A ERW Steel Pipe/tube
The ASTM A135 ERW steel pipes are intended for conveying gas, vapor, water or other liquid; only Grade A is adapted for flanging and bending. The selection of this ERW pipe for various applications depends on its dimensions, properties, and conditions of service. The pipe may be furnished either non-expanded or cold expanded at the option of manufacturer. When pipe is cold expanded, the amount of expansion shall not exceed 1.5% of the outside diameter of pipe size.

Seamless steel pipe surface defects roll mark removal method
First, mechanical grinding method, Mechanical grinding method is one of the more commonly used methods for removing surface defects of steel pipe, it can be through the grinding wheel, emery cloth, sandpaper and other abrasives to grind off the surface defects. However, this method is relatively time-consuming, requires multiple grinding to completely remove defects, and the grinding process is prone to form new surface defects. Therefore, the number of mechanical grinding should be minimized, while paying attention to the size of the grinding force to avoid excessive damage to the steel pipe.
