Construction API 5L ASTM A500 Carbon Steel ERW Tube

Construction API 5L ASTM A500 Carbon Steel ERW Tube

Outer Diameter : 114.3mm - 812.8mm (4 " - 32 " ) Construction ERW Carbon Steel Pipe

Electric resistance welded (ERW) pipes are formed from steel coils using a continuous process that involves unfurling the coils, feeding the steel plates through tube mills, and then joining the edges longitudinally using electronicresistance welding. Misalignment of the plate edges can result in a deviation of the weld throughout the entire forming process.

Steel structure is the biggest advantage is to people to the functional requirement of the building, sensory demands and economic benefits together perfectly. Steel tube structure with its superior performance, the application of rapid development in recent years, application scope almost involve all fields structure, including buildings, Bridges and offshore platform structure and tower mast, etc.

Compared with the ordinary steel structure, the advantages of steel structure is as follows:

1, Compared with the ordinary open section steel, in the form of circular tube and square (torque) section has a smooth surface, no dead Angle and appearance characteristics of the area is small, it helps save anti-corrosion and fireproof coatings, easy to dust.

2, Small steel pipe section of the wind resistance coefficient, applied to the exposure to the fluid (wind, water)Who has obvious advantages.

3, The structure of the steel pipe internal space available. Filling concrete (concrete filled steel tube structure), for example, not only can improve the bearing capacity of components, but also can prolong the component fireproof limit (an average of 2 hours); Tube with water, can use the internal water circulation for fire prevention.

4, Pipe to transport liquid, has according to the characteristics of developed oil pipeline bridge, storm sewer, etc.

5, The tube can also put the prestressed cable, applying prestress in the body.
