A New Method to Measure The Wall Thickness of Welded Steel Pipe
This device consists of a measuring head of laser ultrasonic measuring equipment, a motivating laser, an irradiating laser and a convergence optical element that is used to collect lights reflected from the surface of the pipe to the measuring head. The important mass parameter for pipe productio...Read more -
Difference between erw and saw steel pipe
ERW is a electric-resistance welded steel pipe, Resistance welded steel pipe is divided into exchange of welded steel pipe and DC welded steel pipe in two forms. AC welding in accordance with different frequencies are divided into low-frequency welding, IF welding, welding of ultra-IF and high-fr...Read more -
