Large diameter cold drawn seamless steel pipe is more than 1000MM diameter steel pipe, large diameter seamless steel pipe is made of ingot or solid tube perforation made of capillary, and then by hot-rolled, cold-rolled or cold dial made. The large-diameter thick-walled steel pipe we purchase is either long or short or short and can be welded. If it is long, we need to remove the extra part, that is, cut it, and its length is suitable for the length required for construction of the steel pipe. Cutting of large diameter seamless steel pipe are many ways.
Here are three common large diameter cutting method.
1, The use of sawing machine. Sawing machine is characterized by a complete incision and construction of the welding convenience, the disadvantage is that the efficiency is too low, that is too slow.
2, The use of artificial gas cutting. Features are fast, high efficiency, the disadvantage is that the surface of the incision at the sawtooth shape, hinder and construction.
3, The use of pipe self-propelled automatic cutting machine. The use of pipe self-propelled automatic cutting machine is characterized by low cost, cutting mouth at the smooth and neat, after the use of pipe self-propelled automatic cutting machine after cutting a large diameter cold drawn seamless steel pipe and cut the use of sawing machine is not too large the difference.
