Product Description:

1. Structure of Hollow Section Description: 

Hollow section is a type of metal profile with a hollow tubular cross section. Hollow section, especially rectangular sections, are commonly used in welded steel frames where members experience loading in multiple directions. Square and circular hollow section have very efficient shapes for this multiple-axis loading as they have uniform geometry along two or more cross-sectional axes, and thus uniform strength characteristics. This makes them good choices for columns. They also have excellent resistance to torsion. Hollow section can also be used as beams, although wide flange or I-beam shapes are in many cases a more efficient structural shape for this application. However, the hollow section has superior resistance to lateral torsional buckling.



2. Main Features of the Hollow Section: 

• High manufacturing accuracy

High strength

Small inertia resistance

Strong heat dissipation ability

Good visual effect

Reasonable price

Q:What's the difference between No. 20 steel pipe and 27SiMn Steel Pipe?
Cold plastic deformation and for bending, rolling, bending and hammer arch processing, arc welding and contact welding welding performance is good, when the thickness is small, prone to strict requirement of shape crack or complex shape parts. The cold or normalizing condition of cutting is better than that of annealing. It is generally used to make the material with little force and high toughness.
Q:How are steel tubes represented?
If you speak of steel pipe, if it is water. Gas transmission pipe, then it is said: nominal diameter refers to the inner diameter. The units are millimeters or inches. [for example, water pipes with phi 25. It means that the nominal diameter (diameter) is 25mm (or an inch) steel pipe.
Q:Welded and seamless steel pipe how to distinguish?
Generally, careful observation, can see traces of the weld seam pipe, further is the determination of the polished incision, and then with the file can be seen there is no clear cut, interface traces with the file cleanup to remove when cutting was pasted interface.
Q:Difference between cold rolled steel pipe and common steel pipe
3, the caliber of cold-rolled steel tube is smaller than that of hot rolled steel tube4, from the price point of view, cold-rolled steel pipe is 1000-2000 tons more expensive than hot-rolled steel pipe
Q:How long are the seamless tubes? Are they six meters long?
The length of the seamless tube is 3000~12000mm, including 6 meters.
Q:The difference between 12Cr1MoVG alloy steel tube and 15CrMo
15CrMo is a steel Pearlite Heat-resistant steel, has high heat resistance at high temperature (b = 440MPa) and antioxidant activity, and has certain ability of anti hydrogen corrosion. Because of the high content of Cr, C and other alloy elements in steel, the tendency of hardening of steel is obvious, and the weldability is poor.
Q:What quota should be installed for heating seamless steel pipe?
Seamless steel pipe having a hollow cross section, used as a conduit for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials.
Q:What is the difference between steel pipe and round steel?
Making ring parts with steel tubes can improve data application rate, simplify manufacturing process, save data and work hours, such as rolling bearings, rings, Jack sleeves, etc., and have been widely used in steel pipe manufacture.
Q:Which is cheaper, angle iron or steel pipe?
The model does not mean the size of the different edges and sizes of the same model. Therefore, the width, the edge and the thickness of the angle iron should be filled out in the contract and other documents, so as not to be indicated by the model alone. Standard Specification for hot-rolled equal angle iron is 2#-20#. The angle iron can be made up of different force components according to the different structure, and can also be used as the connecting piece between the components. Widely used in a variety of architectural and engineering structures, such as beams, bridges, towers, hoisting and conveying machinery, ships, industrial furnace, reaction tower, container frame and warehouse.
Q:Is the electric pipe used with steel pipe or PVC pipe?
In industrial designs, galvanized steel tubes are generally used for laying electric tubes, especially in the case of explosion protection.The benefits of galvanized steel pipe is not easy to damage, can prevent the destruction and damage of environmental forces to a certain extent, a junction box, check for export, export lines and other accessories, construction and maintenance in explosion-proof environment can be exempted from hot work. The disadvantage is higher cost.The PVC tube is less costly, but less impact resistant.
