What are the cutting methods of large diameter cold drawn seamless steel pipe?

The large diameter cold drawn seamless steel pipe is a steel pipe with an outer diameter of more than 1000mm. The large diameter seamless steel pipe is made of steel ingot or solid billet through perforation and then hot rolling, cold rolling or cold drawing. The large-diameter thick wall steel pipes purchased by us are long or short. If they are short, they can be welded. If they are long, they need to remove the redundant parts, that is, cut them out. Their length is suitable for the length required by the construction of steel pipes. There are many ways to cut large diameter cold drawn seamless steel pipe.

Here are three common methods of large diameter cutting.
1. Use a saw. The feature of sawing machine is that the cut is neat and convenient for welding in construction. The disadvantage is that the efficiency is too low, that is to say, too slow.
2. Cut with artificial gas. It is characterized by fast speed and high efficiency. The disadvantage is that the surface of the cutting mouth presents a zigzag shape, which hinders the construction.

3. Use the pipeline self-propelled automatic cutting machine. The features of using the pipeline self-propelled automatic cutting machine are low cost, smooth and neat cutting points. After using the pipeline self-propelled automatic cutting machine to cut the large-diameter cold drawn seamless steel pipes, there is not much difference between the cutting points of using the saw machine and the steel pipes.
