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.
Square cold-formed hollow section steel is a section steel with square cross-section shape and size made of hot-rolled steel plate after cold-bending and then high-frequency welding. It is also called welded square steel pipe. The section steel has a stable production process and high precision, and
The straight seam welded pipe unit sends the strip steel into the welded pipe unit, and after rolling by multiple rollers, the strip steel is gradually rolled up to form a round tube billet with an opening gap. Adjust the reduction of the extrusion roller to control the weld seam gap at 1~3mm, and m
First of all: in the process of use, we must strictly operate in accordance with the operating procedures in the instruction manual, let alone overload the machine and use it, and before complaining about the production, that is, the operation of the machine, we must check all aspects of the machine
