Large diameter seamless steel pipe is over 1000MM, which is made from steel ingot or solid tube, and then processed by hot rolling or cold rolling. Sometimes, the seamless steel pipes is long or short while using. Short seamless steel pipes can be welded, long seamless steel pipes can be cut off. Here are three methods of cutting large diameter seamless steel pipes to proper length to meet industry needs.

1. By saw machine

Saw machine can make neat section which is convenient for welding. The disadvantage is low efficiency.

2. By gas cutting

Though gas cutting is fast, the disadvantage is presented notched surface which is not good for construction.

3. By cnc cutting machine

By cnc cutting machine, seamless steel pipes manufacturers will not save a lot cost but also can obtain smooth section of seamless steel pipe which has not much difference from cutting by saw machine.
