Seamless steel pipe with hollow section, a large number of pipes used for conveying fluid, such as the transmission of oil, natural gas, gas, water and some solid materials such as pipeline. Steel pipe and round steel and other solid steel compared to the same bending strength, the weight is light, Seamless Steel Pipes is an economic section of steel, widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, car drive shaft, bicycle Racks and steel scaffolds used in construction, etc., can improve the utilization of materials, Seamless Steel Pipes simplify the manufacturing process, save materials and processing time, has been widely used to manufacture steel.
Seamless steel pipe is widely used. General use of seamless steel pipe from the ordinary carbon structural steel, low alloy structural steel or alloy structural steel rolling, the largest output, mainly used for conveying fluid pipe or structural parts. .2, according to the use of different sub-three supply: a, Seamless Steel Pipes according to chemical composition and mechanical properties of supply; b, according to the mechanical performance supply; c, according to the hydraulic test supply. According to a, b class supply of steel, Seamless Steel Pipes such as for the use of liquid pressure, but also for water pressure test. 3, the special purpose of the seamless pipe with a seamless pipe, geological seamless steel pipe and seamless steel pipe and so on.
Seamless steel pipe is now widely used in the field, such as in the construction, transportation, etc., the reason why the seamless steel pipe can be a lot of time, there must be a steel pipe's strengths and advantages. Than the use of the kind of general steel pipe, seamless steel pipe with a series of messy high-tech manufacturing technology, and then have a seamless steel pipe has a very good quality.
General use of seamless steel pipe is 10,20,30,35,45 and other high-quality carbon steel 16Mn, 5MnV and other low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other synthetic steel made of hot-rolled or cold-rolled. 10,20 and other low-carbon steel seamless pipe is mainly used for fluid pipeline. 45,40Cr and other carbon steel made of seamless pipe used to manufacture mechanical parts, such as cars, tractors force parts. Generally use seamless steel pipe to ensure strength and flattening test.
Seamless steel pipe used in the cold-drawn hot-rolled production process. Seamless Steel Pipes Which makes the pipeline itself becomes very tough, torsional strength is more strong. This can make any industry, for the pipeline, some of the more complex processing, and the pipeline itself, and will not be any changes. And seamless steel pipe, belonging to a section of steel, in the pipeline inside, not all are solid. But in the pipeline inside, Seamless Steel Pipes has a part of the hollow level. Which makes the pipeline, in its own weight, there has been a big reduction. Which for some, for the weight of the pipeline, with strict requirements of the industry, is definitely the best choice.
