Rectangular steel pipe specification sheet
Rectangular tube product description
Rectangular tube is a kind of light thin-walled steel tube with hollow rectangular cross section, also known as cold-formed steel. It is made of Q235 hot-rolled or cold-rolled strip or coil, which is cold-formed and then welded by high frequency.
In addition to the thickening of wall thickness, the corner size and edge flatness of hot-rolled ultra-thick-walled rectangular tube reach or even exceed the level of resistance welding cold-formed rectangular tube. Good comprehensive mechanical properties, weldability, cold and hot workability and corrosion resistance, and good low temperature toughness. Application of Rectangular Tube
Rectangular tubes are used for high-load welded structural parts such as construction, machinery manufacturing, steel structure and other special projects, shipbuilding, solar power generation brackets, steel structure engineering, power engineering, power plants, agricultural and chemical machinery, glass curtain walls, automobile chassis, airports, boiler construction, highway railings, housing construction, pressure vessels, oil storage tanks, bridges, power station equipment, lifting and transportation machinery.
The technology of stainless steel seamless pipe determines its limited performance. Generally, seamless steel pipe has low precision, uneven wall thickness, low brightness inside and outside the pipe and high length cost.
As the main steel, steel pipe is widely used in our daily life.
In the fields of oil and gas transportation, building structure grid manufacturing, highway and bridge manufacturing, etc. It can be said that the steel pipe not only lightens the weight of the support and saves building materials, but also makes the construction easier and easier. Presumably, in steel trading and construction, it is necessary to know the weight of steel pipes. What is the precision seamless steel pipe like?
Process description: high-quality carbon steel, finish rolling, bright heat treatment without oxidation (NBK state), nondestructive testing, scrubbing the inner wall of the steel pipe with special equipment, high-pressure washing, antirust oil on the steel pipe as antirust oil, and dust-proof treatment for sealing at both ends.
The technology of stainless steel seamless pipe determines its limited performance. Generally, the precision of seamless steel pipe is low: uneven wall thickness, low brightness inside and outside the pipe, high cost of length, and difficult removal of internal and external pits and black spots; Its detection and shaping must be done offline. Therefore, it shows its advantages in high pressure, high strength and rectangular surface of mechanical structural materials.
