Difference between steel jacket steel insulation steel pipe and ordinary steel pipe

In our life, no matter where we are, we can see the steel sheathed steel insulated steel pipes. However, our understanding of steel pipes is really narrow. We think that there is only one kind of steel pipe. In fact, there are two kinds of steel pipes used in our life, that is, steel sheathed steel insulated steel pipes and ordinary slotted steel pipes. Moreover, these two kinds of steel pipes are completely different in terms of production and use, But it's impossible without anyone.

At present, most of the steel pipes used in our life are steel insulated steel pipes. In fact, the steel insulated steel pipe is a hollow section, and there is no weld or other linked steel in the pipe. Moreover, the manufacturing process of the steel insulated steel pipe is very troublesome. First, the solid pipe should be perforated to make the predecessor of the steel insulated steel pipe, Then, the steel pipes for different purposes will be produced by cold rolling or hot rolling. Compared with the ordinary round steel pipes, the pressure resistance of the steel insulated steel pipes is very strong, and the weight of the steel pipes is also very light. Such steel insulated steel pipes are also used in various fields of life, such as construction, transportation, parts, etc.

One kind of steel pipe that will be used in life is the slotted steel pipe. This steel pipe is welded after the plane steel is twisted. Therefore, welds will be left on the outside of this kind of steel pipe. The use area of the slotted steel pipe is relatively narrow. It is generally used in the transportation of water and coal gas, and the service time is far longer than that of the steel jacket steel insulation steel pipe, Moreover, many slotted steel pipes will be subject to non-human fracture and damage during installation, and the quality needs to be improved.
