Seamless pipe

After cutting, an angle grinder should be used to grind the plastic layer of the nozzle.

The ultrasonic probe can realize the mutual conversion between electrical energy and sound energy, and the physical characteristics of ultrasonic waves when they propagate in elastic media are the basis of the principle of ultrasonic flaw detection of seamless steel pipes.

If the heating temperature is too high or the heating time is too long, it will cause the zinc ash to adhere to the surface layer of the cold-drawn seamless tube blank substrate, which is difficult to eliminate.

Seamless steel pipes are mainly caused by the strong reaction of iron and zinc.
