Q:What is the difference between hot dip galvanized steel pipe and galvanized steel pipe?
The difference between the process is that the hot dip galvanized pipe is dipped in the molten zinc bath and the galvanized pipe is plated with a metallic surface by means of unidirectional current in the plating bath. Hot plating process is fast, the coating is thick and consumes more zinc. Ordinary galvanized slow speed, thin coating.
Q:Galvanized steel pipe, PPR pipe, PE pipe, U-PVC pipe and HDPE double wall corrugated pipe and what is the difference between the characteristics of
PE pipe, polyethylene pipe, the past is also commonly used in low temperature water, but because of its short life now use less prone to aging, more PE material for the production of plastic bags;
Q:There are multiple welded galvanized steel pipe outer diameter 108mm wall thickness 4mm length of 6 meters
Galvanized steel pipe wall thickness weight outer diameter 108mm 4mm 6 meters in length is about 10.26*6*1.06=65 kg.Kg/m= (outside diameter mm-, wall thickness mm) * wall thickness mm*0.02466= (108-4) *4*0.02466=10.26 kg / MBecause of galvanizing, the weight is heavier than that of ordinary welded pipe 3%~6%.
Q:What is the outer diameter of the steel tube?
The outer diameter refers to the maximum diameter including the thickness of the steel tube, the inner diameter is the length of the hollow part inside, and the outer diameter minus the inside diameter is the thickness of the steel pipe
Q:Difference between cold rolled steel pipe and common steel pipe
1, from the dimension accuracy above, cold-rolled steel pipe size is good, high precision2. from the outward appearance, the surface of cold-rolled steel pipe is bright, and the surface of hot rolled steel pipe has obvious oxide skin or red rust
Q:What's the difference between stainless steel seamless tube and stainless steel welded pipe?
Stainless steel seamless pipe featuresFirst, the product of the wall is thicker, it is more economical and practical, the wall thickness of the thinner, processing costs will be substantially increased it; secondly, the product process to determine its performance limitations, generally low precision seamless steel pipe: uneven thickness, tube inner surface brightness low and high cost of fixed length, and the inner surface pitting and black spots difficult to remove; the detection and plastic third, must be processed offline. Therefore, it has its advantages in high pressure, high strength, mechanical structure and timber.
Q:How long is the seamless tube?
Seamless steel tube specification: 8-1240 * 1-200mm
Q:What's the difference between hot-rolled seamless steel tube or cold-rolled seamless steel tube?
Cold rolled seamless steel pipe (DIAL) in general, steel pipe for low and medium pressure boiler tube, high-pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking tube and other steel tube, including carbon thin-walled steel, alloy thin-walled steel, stainless steel, thin steel tube.
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:Is the same specification seamless steel pipe more expensive than welded pipe?
You need to see this in the interval that diameter, such as seamless pipe and welded steel tube 530*20 mm compared to 5450 yuan per ton, seamless pipe, welded steel pipe, which is 4550 yuan, small diameter 10*2 mm, seamless pipe will require far 10000 per ton, just need more than 6000
