Q:25 of the steel pipe with 6 in charge of what is the difference?
Outer diameter representation of steel pipe:When the design is nominal diameter DN means diameter, should be nominal diameter DN and the corresponding product specifications table. Specification for unplasticized polyvinyl chloride pipes for building drainage, de (nominal outer diameter) * e (nominal wall thickness), (GB, 5836.1-92), polypropylene (PP) pipe for water supply, specifications by de * e (nominal outer diameter * wall thickness).
Q:Seamless steel pipe is how to do it?
Round tube has some limitations, such as in the plane bending conditions, the tube is better than square and rectangular tube bending strength, and some agricultural machinery skeleton, steel, wood furniture, commonly used square, rectangular tube. According to different purposes, other sections of special-shaped steel pipe are needed.
Q:SC15 what does galvanized steel pipe look like?
Ordinary galvanized steel pipe, the outer diameter is 1.5 inches
Q:What does the diameter of a steel pipe project mean?
Nominal surface meaning can be understood as a public address. It's as if everyone agreed to call something as a "devil", and he was the devil.Don't be confused by the numbers behind the nominal diameter. For example, DN50, this 50 is really close to the outer diameter or inside diameter of the steel tube, but DN50 is only a general model of the caliber of the national standard.
Q:What is the theoretical weight per square meter of the steel pipe diameter of the outer frame and the thickness of the tube wall 3mm 48mm?
The outer steel tube diameter is 48mm, the tube wall thickness is 3mm, the theoretical weight per meter is 3.3291kgCalculation formula: (outside diameter wall thickness) * wall thickness *0.02466(48-3) *3*0.02466=3.3291kg
Q:What's the difference between straight steel pipe and seamless steel pipe?
The welded pipe is made of rolled steel plates, and small ones are straight welded, and big ones are spiral welded. Because the welded pipe has weld, the mechanical performance of weld is poor, so its applicable range is limited, but its price is cheap. Significant difference is that there are welded pipe, seamless steel pipe is not, of course, the welded pipe treatment of good, layman do not see the difference.
Q:Are there specifications for scaffold steel pipe with 48mm * 3.2mm?
Previously used steel pipe GB 51*3.0mm, the latest national standard JGJ130-2001 stipulates that the use of steel pipe for construction projects need to be 48*3.5mm specifications, the wall thickness should be 3.5mm square for qualified products.
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:What do you mean by "SC" in welded pipe SC200? What's the diameter of 200?
Including galvanized steel pipe, but galvanized steel pipe is generally used for plumbing professional, electrical professional generally only civil air defense or high anti-corrosion requirements of the region;
Q:Seamless steel pipe 8162 and 8163 what is the difference?
GB 8162 is the structure of the tube, there is no need for flaw detection, the use of mechanical processing, stents;
