Seamless Steel Pipe
1.Appearance, seamless steel pipe and welded steel pipe have different welding reinforcement on the welded pipe wall
2.Pressure, Seamless pipes require higher pressure during production. Welded pipes usually have about 10 MPa when manufactured.
3. The seamless steel pipe is formed once during the rolling process. Welded steel pipes need to be rolled and welded, usually spiral welding and direct welding. The performance of seamless pipes is better, and of course the price is higher.
Carbon Steel Pipe
Steel pipe classification: Steel pipes are divided into seamless steel pipes and welded steel pipes (seamless pipes). According to the cross-sectional shape, it can be divided into circular tubes and special-shaped tubes. Round tubes are widely used, but there are also some square, rectangular, semicircular, hexagonal, equilateral triangle, octagonal and other special-shaped tubes.

Seamless steel tube: The seamless steel tube is perforated with steel ingots or solid billets, and then hot rolled, cold rolled or cold drawn. The specifications of seamless steel pipes are expressed in mm outer diameter * wall thickness. Seamless steel pipes can be divided into hot-rolled and cold-rolled seamless steel pipes.
1. For raw materials, if you want to use stainless steel welded pipe equipment for normal processing, you must pay attention to the problems of the raw materials during transportation or loading and unloading, and try not to cause bumps or scratches.
2. For the used site, the processing site should be stable, and some bedding should be made on the workbench for reprocessing, so as to avoid the phenomenon of scratching the steel pipe on the workbench during operation.
3. When performing cutting construction, for the raw materials to be welded, either shearing or plasma cutting is used. When cutting, use something like rubber for paving.
4. After using stainless steel welding equipment for welding, clean the surface in time to ensure the best construction effect.
5. For the completed welding construction, it is necessary to do a good job in the protection construction of the finished product, try not to touch and other phenomena, so as to effectively avoid secondary pollution.
From their definition, we can see that one has no gaps and the other has gaps. And the seamless steel pipe can be seen from the outer surface, there is no gap in the whole body; the welded steel pipe has a welding gap. The price of seamless steel pipes is generally higher than that of welded steel p
In recent years, my country's ERW tube mill line production has developed rapidly. According to relevant information, there are more than 1,600 sets of various welded pipe production lines, with an annual production capacity of 7 million tons, and product specifications ranging from 8mm*1mm to 508mm
First of all, the welded pipe process is an important link in the ERW High Speed Tube Mill production line, which can directly affect the quality of the products produced. The production process depends on the product variety. From raw materials to finished products, a series of processes are requir
