Q:How to descaling galvanized steel pipe?
If the substrate is rusty, rust removal can be removed by acid leaching. If the coating is rusted, it can also be dipped in acid, but this will also remove the coating and make the base material more susceptible to rust, preferably by re plating and passivation
Q:How to distinguish seamless pipe and welded pipe?
The way to distinguish seamless pipes and welded pipes is to see if there is weld marks on the port.
Q:Outside diameter 60, thickness 3.5 seamless steel tube, how many kilograms per meter?
Steel tube Kg/m (including seamless steel tubes and welded tubes) theoretical formula per meter weight: W=0.02466 * S * (D-S)Of which: S - wall thickness (mm), D - steel tube diameter (mm), W - kg / M
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?
Formula: outside diameter - wall thickness * wall thickness *0.02466=, weight per meter! : 48-3*3*0.02466=3.3291
Q:What's wrong with the 3PP anticorrosive steel tube?
PP and PE are similar in processability, and the 3PE coating can be used to produce 3PP coatings without the need for a special 3PP coating line. However, the difference between PP and PE materials makes the 3PP and 3PE coatings show different properties, which can be applied to different environments. The advantages of 3PP coating on some properties make it possible to play an important role in the field of 3PE coating. Therefore, many foreign pipeline projects use 3PP anticorrosive coating.
Q:What's the difference between the fastener type steel pipe scaffold, the floor type steel pipe scaffold and the overhanging type steel pipe scaffold?
Classification is not the only way, fastener type steel pipe scaffolding is divided by force, and the latter 2 are classified according to the structure.
Q:What's the difference between seamless steel pipe and welded pipe?
Use, seamless steel pipe is generally used in the condition of higher use, such as temperature and pressure higher, corresponding to the requirements of stress corrosion, seamless steel pipe. With vice.
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:Does the seamless steel pipe need rust removal?
Spray (throw) shoot derusting by the high-power motor to drive the spray shot (impeller) blade rotating speed, the steel grit, steel shot, iron wire, minerals and other abrasive jet for 20# seamless steel tube surface under the action of centrifugal force (left) radiation treatment, not only can completely remove the dirt and rust, oxide, and the role of 20# seamless steel in abrasive blast and friction force, can achieve the required uniform roughness.Not only can the physical adsorption effect on the surface of the pipe be increased, but also the mechanical adhesion of the anticorrosive layer to the pipe surface can be enhanced. Therefore, spraying (throwing) shot derusting is an ideal method of rust prevention for pipeline corrosion protection. Generally speaking, shot peening (sand) derusting is mainly used in the inner surface treatment of tubes, shot blasting (sand) derusting is mainly used for the outer surface treatment of tubes.
Q:304 stainless steel tube with the diameter of 25*2-3 is what mean
The quality of the steel pipe should be in line with the national standard "stainless steel seamless pipe for fluid transportation" (GBT 14976-2012) requirements.
