Product Description:

 

1Structure of Round Pipe : 

Seamless pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable. Historically seamless pipe was regarded as withstanding pressure better than other types, and was often more easily available than welded pipe. 

 

2‍‍Main Features of Round Pipe:

• High manufacturing accuracy

• High strength

• Small inertia resistance

• Strong heat dissipation ability

• Good visual effect

• Reasonable price

Q:What does "spiral welded steel pipe" DN325*10 mean?
Spiral welded steel pipe with nominal diameter of 325mm and wall thickness of 10mm
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's the difference between steel pipe and pipe fittings?
Pipe classification: steel pipe seamless steel pipe and welded steel pipe (tube) two categories. It can be divided into round tube and special-shaped tube according to the sectional shape. The round steel tube is widely used, but there are some special-shaped steel tubes such as square, rectangle, semicircle, hexagon, equilateral triangle and octagon.
Q:Seamless steel tube with the tube with what is the difference?
Seamless steel tube is integrally formed with welded steel pipe steel plate butt welding and welding seam.
Q:Are steel tubes and round steel in weight or length when purchased?
It's priced by weight. The cutting process should size to determine the length (otherwise - please specify the weight of the material), the material ration to calculate weight for cost accounting as.
Q:What are the main types of steel pipe ah? How to judge which kind of steel pipe performance is better?
Welded steel pipe for different welding process and divided into the furnace pipe welding (ERW) pipe and automatic arc welding, because of the different forms of welding seam welded pipe and spiral welded pipe is divided into two kinds, end its shape is divided into circular welded and shaped (square, flat) pipe.The welded pipe is rolled into the steel tubular to sew or spiral seam welded in the manufacturing method, and is divided into low pressure fluid delivery with welded steel pipe, spiral welded steel pipe, welded steel pipe, welded pipe roll etc.. Seamless steel pipe can be used in various industries, such as liquid, pneumatic, pipeline and gas pipeline. Welding pipes can be used in water pipelines, gas pipelines, heating pipes, electrical appliances, pipelines and so on.Press materialSteel pipe according to the pipe material (ie steel) can be divided into: carbon tube and alloy tube, stainless steel tube.Carbon tube can be divided into ordinary carbon steel tube and high quality carbon structure tube.The alloy tube can be divided into: low alloy pipe, alloy pipe structure, high alloy tube, high strength tube. Bearing tube, heat resistant acid resistant stainless pipe, precision alloy (such as cutting alloy) pipe, high temperature alloy tube, etc..
Q:What is the difference between galvanized iron pipe and galvanized steel pipe? Or called different, in fact, is referred to as galvanized pipe?
Just name different, all refers to GB/T 3091-2015 "low pressure fluid transport welding pipe" contained in the galvanized pipe.Galvanized pipe means zinc plated, suitable for water, air, heating, steam and gas and other low pressure fluid conveying straight welded steel pipe, longitudinal submerged arc welding (SAWL) steel pipe and spiral seam submerged arc welding (SAWH) steel pipe.
Q:Outside diameter 60, thickness 3.5 seamless steel tube, how many kilograms per meter?
Other commonly used theoretical weight formulas per metre:Thread steel (Kg/m):W=0.00617 * D * D, D - sectional diameter (mm)Fang Gang (Kg/m):W=0.00785 * a * a, a - edge width (mm)Flat steel (kg/m):W= 0.00785 * b * D, B -- edge width (mm) d - thickness (mm)Round steel rod (kg/m),:W= 0.006165 * D * D, D - diameter (mm)
Q:Seamless steel tube 89X4 meters, how heavy?
According to the theory, each meter is 8.3844 kilograms. If you want to be precise, you'll lose your own weight.
Q:How much is the wall thickness standard of building 48?
According to the "construction of fastener type steel pipe scaffold safety technical specifications JGJ130-2011" stipulates that the specification of steel pipe should be Phi 48.3 * 3.6, that is, wall thickness is 3.6mm.
