Thick-walled seamless square pipe is a square steel pipe with four corners, which is a square steel pipe formed by cold drawing and extrusion of seamless steel pipe. In addition to the thickening of the wall thickness of the hot-rolled extra-thick-walled square tube, its corner size and edge straightness have reached or even exceeded the level of the resistance-welded cold-formed square tube. Thick-walled seamless square tubes are used in construction, machinery manufacturing, steel construction projects, shipbuilding, solar power brackets, steel structure engineering, power engineering, power plants, agricultural and chemical machinery, glass curtain walls, automobile chassis, airports, boiler construction, etc.
In addition to the thickened wall thickness of the thick-walled seamless square tube, its corner size and edge straightness have reached or even exceeded the level of the resistance welded cold-formed square tube.The size of the R angle is generally between 2 and 3 times the wall thickness. According to the needs of customers, we can also produce R-angle square tubes of the size required by customers;
Performance characteristics of thick-walled seamless square tube
1. The weight of the structure is light, the weight of reinforced concrete is light, the net weight of the structure is relieved, and the internal work of the structure is reduced,
2. The construction structure of the project can consider low regulations, the construction weight of the project is lighter, the project cost is reduced, and the reasonable total work area of the construction site can be filled. According to the different methods of project construction, 4-6% of the reasonable total work area can be filled.
3 The structure of the thick-walled seamless square tube has high invariance. The steel frame structure based on the hot-rolled thick-walled seamless square tube has the characteristics of reasonable configuration, good plastic deformation and softness, and high structural reliability. It is suitable for building structures with high vibration and high intrusion load, can resist flood disasters, and is very suitable for engineering construction structures in some multiple earthquake fault zones.
Thick-walled seamless square tube weight calculation formula
Thick-walled square tube weight=4*wall thickness*(side length-wall thickness)*7.85
The general difference between seamless square tube and welded square tube
1. Welded square tube is a hollow square section steel square tube, also known as hollow cold-formed steel. It is a section steel with a square cross-section shape and size made of hot-rolled or cold-rolled strip or coil as a blank, cold-bending, and then high-frequency welding.
2. Seamless square tube is a long steel with a hollow section and no joints around it. It is a square tube formed by extruding a seamless tube through the four sides of the die. The seamless square tube has a hollow section and is widely used in liquid transportation, hydraulic support, mechanical structure, medium and low pressure, high pressure boiler tubes, heat exchange tubes, gas, petroleum and other industries. It's stronger than welded and won't crack.
