Structural Steel Pipe Supplier, Manufacturer, Exporter
The structure steel pipe has hot – rolled seamless steel tube and welded steel tube. The seamless steel tube for structure, divided into two types hot rolling and cold drawing. The outer diameter of hot-rolled steel pipe is 32-630mm and the wall thickness is 2.5-75mm. The outer diameter of cold-drawn steel pipe is 5-200mm and the wall thickness is 2.5-12mm.
Welded steel pipe is made of steel plate, steel strip after crimping and forming, which can be divided into straight welded steel pipe and spiral welded steel pipe. The outer diameter and wall thickness of the direct-welded steel pipe are 5-508mm and 0.5-12.7mm respectively. The welded steel pipe for low-pressure fluid transportation. also called common welded pipe, commonly known as clark pipe.
The specification is expressed in mm of nominal diameter, which should comply with the provisions for low-pressure fluid transportation.
Size:OD: 1/8” ~ 26” (10.3 ~ 660mm)，WT: SCH 10 ~ 160, SCH STD, SCH XS, SCH XXS LENGTH: Fixed Length (5.8/6/11.8/12mtr), SRL, DRL
Standard & Grade:ASTM A53/A252/A500/A501, JIS G3444, EN 10210/10219…
Calculation method of structural steel pipe: weight of structural steel pipe = 0.25 ×π×( Outer diameter square – inner diameter Square) × L × Proportion of steel
Among them: π = 3.14 L = structural steel pipe length, steel specific gravity 7.8
