Q:Difference between seamless steel pipe and welded pipe
Welding pipes can be used in water pipelines, gas pipelines, heating pipes, electrical appliances, pipelines and so on.
Q:The difference between carbon and welded steel tubes
Quality solutionsThe carbon steels we usually refer to include carbon structural steels and carbon tool steelsThe common steel pipe is divided into two kinds: seamless steel pipe and welded steel pipe. The welded pipe of small size is straight welded, and the big size steel pipe is usually spiral welded
Q:What are the lengths of scaffold steel tubes?
Scaffolding steel pipe standard length is 6 meters, for easy use, respectively, 6 meters, 3 meters, 2 meters, 1.5 meters, 1 meters, etc., if there is a special length, you need to intercept.
Q:What's the use of steel pipe?
(processing workshop of Tianjin steel pipe company as a result of the steel pipe truss structure, the actual steel saving up to 42.9%), with a steel pipe manufacturing highway bridge can not only save steel, simplify the construction, but also can greatly reduce the coated area, saving investment and maintenance costs.
Q:What is lined pipe?
Is the coating of the inside of the pipe, such as pipe conveying sulfuric acid will corrode, corrosion, but soft plastic pipe, buried in the ground to wall thicker, then you can use the liner and characteristics of hard for using steel pipe laying, sheathed in the steel pipe into the thin plastic tube, it can transport the sulfuric acid,
Q:Is there a weld on the outer wall of seamless steel tube?
Seamless steel pipe, not seamless steel pipe, seamless steel pipe, welded seam, how can it be called seamless pipe?. Tell you a method: measurement of wall thickness, multi test several points, if each point, that is because it is cold drawn pipe, seamless pipe, hot rolling, wall thickness may% by sample.
Q:Is the seamless steel pipe used in the market hot or cold drawn?
Outside diameter 89, most are cold drawn, more than 89 hot rolling.
Q:Seamless steel tube 89X4 meters, how heavy?
The theoretical weight calculation formula of plain carbon steel and alloy steel seamless pipe:W=0.02466 (D-S) S, the density of steel fand 7.85kg/dmNote: weight per meter kg/m= (outer diameter wall thickness) * wall thickness *0.02466 units, mm: mmFor example, the seamless steel pipe with a diameter of 89*4 weight per meter:(89-4) *4*0.02466=8.384 kg / M.
Q:Can stainless steel pipes spray black paint?
Yes, after painting, I usually touch hands and paint off in 2 years or so
Q:What kind of argon arc welding wire is used for 16Mn steel pipe?
16Mn steel belongs to carbon manganese steel, the content of carbon is about 0.16%, and the yield point is equal to 343MPa (strength grade is 343MPa). 16Mn steel alloy content is less, good weldability, welding generally without preheating. But because the 16Mn steel hardened tendency is slightly larger than the low carbon steel, so at low temperatures (such as winter outdoor operations) or welding in high rigidity, large thickness of the structure, in order to prevent the cold crack, need to take measures to preheat.
The company has successively passed ISO9000 quality system, the American Petroleum Institute API, and also earned the environment healthy license, national special equipment manufacturing license.
