Large diameter seamless steel pipe is over 1000MM, which is made from steel ingot or strong tube, and after that processed by hot rolling or cool rolling. Occasionally, the smooth carbon steel pipeline is longer or brief while utilizing. Short smooth steel pipes can be welded, much longer seamless steel pipelines can be cut off. Below are 3 techniques of reducing big diameter smooth steel pipelines to correct length to satisfy sector structural steel supply needs.

1. By saw device Saw device can make neat area which is hassle-free for welding. The disadvantage is low efficiency.

2. By gas reducing Though gas cutting is fast, the drawback exists scratched surface area which is bad for building and construction.

3. By cnc reducing device By cnc cutting machine, seamless steel pipelines suppliers will not save a lot cost however also can obtain smooth area of seamless steel pipeline which has very little distinction from cutting by saw maker.
