Hot rolled steel pipes are a type of steel pipe product that offers unique advantages. By refining the grain structure of the ingot, it can destroy the casting organization and eliminate microstructure defects, resulting in improved mechanical properties. Additionally, the market offers a variety of manufacturers, prices, sizes, and specifications to meet the needs of consumers with different requirements. This ensures a high level of product service.
1. the difference between hot rolled steel pipe and cold rolled steel pipe
Cold rolled seamless steel pipes are typically of smaller diameter, while hot rolled seamless steel pipes are typically of larger diameter.
Additionally, cold rolled seamless steel pipes are more precise and expensive than hot rolled seamless steel pipes.
The hot rolled seamless steel pipe is categorized into various types, including general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, geological steel pipe, and others.
In addition to general steel pipe, this category includes cold-rolled (dial) seamless steel pipes for low and medium pressure boilers, high pressure boilers, alloys, stainless steel, and petroleum cracking. It also includes other types of steel pipes, such as carbon thin-walled steel pipes, alloy thin-walled steel pipes, stainless thin-walled steel pipes, and profiled steel pipes.
In addition to general steel pipe, low and medium pressure boiler pipe, high pressure boiler pipe, alloy steel pipe, stainless steel pipe, and petroleum cracking pipe, cold-rolled (dial) seamless steel pipe also includes carbon thin-walled steel pipe, alloy thin-walled steel pipe, stainless thin-walled steel pipe, and shaped steel pipe. It is important to adhere strictly to metrics and units.
2. hot rolled steel pipe, welded steel pipe difference
There are several differences between seamless steel pipes and welded steel pipes.
Firstly, welded pipes have welded ribs on their walls, while seamless pipes do not. Secondly, seamless pipes can withstand higher pressure, typically around 10 MPa, whereas welded pipes require seamless processing to achieve the same level of pressure resistance. Finally, seamless steel pipes are produced through rolling and molding. To produce welded steel pipe, it must first be rolled and then welded. There are two common methods of welding: spiral welding and straight welding. Seamless pipe is considered to have better performance, but it is also more expensive.
Steel pipe is a type of hollow, elongated steel that is commonly used as a pipeline for transporting fluids, such as oil, natural gas, water, gas, and steam. It is also widely used in the manufacture of mechanical parts and engineering structures due to its comparable bending and torsion strength and lighter weight. Additionally, it is commonly used for producing various conventional weapons, gun barrels, shells, and more.
