Q:What material is RHS in the steel tube?
RHS is a rectangular hollow section steel. The RHS structure represents a rectangular hollow section steel.
Q:Difference and application of seamless hot rolled pipe and cold drawn pipe in seamless steel tube
type3.1, seamless steel pipe according to the different production methods can be divided into hot-rolled pipe, cold rolled tube, cold drawn tube, extrusion tube and so on3.2, according to the shape of the classification of circular tubes, special-shaped tubes of the division, except the square tube and rectangular tube, there are elliptical tube, semicircle tube, triangle tube, hexagonal tube, convex shaped tube, plum shaped tube and so on3.3, according to the different material, divided into ordinary carbon structure tube, low alloy structure tube, high quality carbon structure tube, alloy structure tube, stainless steel tube and so on3.4, according to special use, there are boiler tubes, geological pipes, oil pipes and so on
Q:What type of steel pipe dance is used in general?
According to international competition practice, the standard size of steel tube is 40 mm or 45 mm in diameter, and the 45mm is usually used. The height of the steel pipe is not less than 3.3 meters and not higher than 4 meters.
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 does carbon seamless steel pipe mean? What is the difference between a seamless 20# and an ordinary one? What is it used in detail?
Carbon steel is actually relative to alloy steel, mainly carbon content, and 20# seamless steel is carbon steel! In addition, there are stainless steel, stainless steel is considered a kind of alloy steel, but the processing is not the same, the performance is not the same, good looking outside!The description of the material in alloy steel is actually the content of the metal elements in the steel (usually the percentage number).
Q:What's the difference between No. 20 steel pipe and 27SiMn Steel Pipe?
Cold plastic deformation and for bending, rolling, bending and hammer arch processing, arc welding and contact welding welding performance is good, when the thickness is small, prone to strict requirement of shape crack or complex shape parts. The cold or normalizing condition of cutting is better than that of annealing. It is generally used to make the material with little force and high toughness.
Q:How to distinguish between steel pipe and spiral pipe material?
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:Is there any difference between HFW steel pipe and ERW steel pipe?
Resistance welding, as the name suggests, resistance welding is a method of welding by welding electrode after exerting pressure on electrode and utilizing electric current through the contact surface of connector and adjacent zone. High frequency welding: high frequency current through the metal conductor, will produce two kinds of peculiar effects: skin and proximity effects, high frequency welding is the use of these two kinds of effects of steel pipe welding, the effects of the two is based on the high frequency welding metal.
Q:What is a tight steel tube?
The tight steel tube is called "galvanized steel pipe with sleeve connection" or "flat pipe of steel metal for electrical installation". JDG. The utility model relates to a novel protective conduit for an electric circuit. The connecting sleeve and the metal accessory are provided with a wire pipeline composed of screw fastening connection technology, and the utility model does not need to do cross grounding, welding and covering, and the appearance is silvery white or yellow.
Q:How many fasteners are there in a ton of steel tubes?
In general, 180-200 fasteners per ton of steel pipe.
