Q:Hot galvanized steel pipe for use?
Hot galvanized pipe: in order to improve the corrosion resistance of steel pipe, galvanized steel pipe. Galvanized steel pipe hot galvanized and galvanized two kinds, hot galvanized, zinc coating thickness, zinc plating cost is low, the surface is not very smooth.The hot-dip galvanized pipe is an alloy layer that causes molten metal to react with the iron matrix, thus combining the substrate with the two coating. Hot dip galvanizing is the first steel pickling, in order to remove iron, steel pipe surface after pickling, cleaning by ammonium chloride or zinc chloride solution or ammonium chloride and zinc chloride aqueous solution tank, and then into the hot dip tank. Hot galvanizing has the advantages of uniform coating, strong adhesion, long service life and so on. A complex physical and chemical reaction is formed between the steel tube matrix and the molten plating solution to form a corrosion resistant structure with a tight zinc - iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe matrix. Therefore, it has strong corrosion resistance.
Q:How can two smooth steel pipes be joined? The size of the two pipe is different (except for welding)
Rectangular fastener: used for the connection of two vertical intersecting steel tubes. It relies on the frictional force between the fastener and the steel tube to carry the load.Swivel fastener: used for connecting two steel tubes intersecting at any angle
Q:What is the difference between the stainless steel pipe welded pipe and seamless pipe?
Concentricity: seamless tube manufacturing process is the temperature of 2200 degrees F in stainless steel billet stamping a hole, at this high temperature, tool steel by stamping and drawing become soft and spiral form from the hole. Thus, the wall thickness of the pipeline is uneven and the eccentricity is high. Thus ASTM allows seamless pipe wall thickness ratio of the wall thickness difference of seamed tube. Through the seamed tube cold rolling plate precision (per roll width is 4-5 feet) made. These cold rolled plates usually have a maximum wall thickness of 0.002 inches. The steel plate is cut into a width of PI D, in which D is the outer diameter of the pipe. Tube wall thickness tolerance is very small, and the entire circumference of the wall thickness is very uniform.
Q:The outer circle of a seamless steel pipe 50 head into the outer circle of the 40 to close
Cold drawn steel tube and cold rolled steel pipe mill is a complete set of equipment which combines cold rolling, cold drawing, cold rolling and cold drawing to produce pipes. It is a unit for deep processing of hot-rolled pipes or welded pipes.
Q:What do you mean by "SC" in welded pipe SC200? What's the diameter of 200?
200 refers to the diameter of the pipe. Personally, you should be an electrical professional, but the electrical specialty rarely uses the 200 pipe diameter unless it is used when the buried cable passes the road;
Q:What is the meaning of "DN" and "Phi" in the dimensioning of steel pipe diameter and how to apply the mark?
DN refers to the nominal diameter of the pipe, but this is neither the outside diameter nor the inside diameter, and the "Phi" means the outer diameter of the steel pipe. For example, the same nominal diameter of the steel pipe due to its different wall thickness, corresponding to the outer diameter is also different. As can be seen from the chart below:Project control table (commonly used) diameter pressure pipe standard pressure pipe standard pressure pipe standard specification DN- nominal diameter: diameter of large diameter series DN15- 22mm DN20- 27mm DN25- phi, Phi Phi Phi Phi 34mm, DN32- 42mm DN40- 48mm DN50- 60mm DN65-, Phi Phi 76 (73) mm, DN80- 89mm DN100- 114mm DN125- and Phi Phi Phi. 140mm DN150- 168mm DN200- 219mm DN250- phi, Phi Phi Phi Phi 273mm, DN300- 324mm DN350- 360mm DN400- 406mm DN450- 457mm DN500- and Phi Phi Phi Phi, 508mm DN600- 610mm, DN15- 18mm series of small diameter Phi Phi Phi, DN20- 25mm DN25- 32mm DN32- 38mm DN40- 45mm DN50- Phi Phi, Phi Phi Phi 57mm DN65- 73mm, DN80- 89mm DN100- 108mm, DN125- 133mm DN150- 159mm DN200- and Phi Phi Phi Phi, 219mm DN250- 273mm DN300- 325mm DN350- 377mm, Phi phi,
Q:What quota is reserved for buried DN20 steel pipe?
It is an embedded sleeve control sub item, if the reserved hole, then there is no need to cover, special subject structure adjustment factor of the cost of the water supply and drainage engineering, water supply and drainage engineering he is buried under the charge.
Q:What's the difference between hot-rolled seamless steel tube or cold-rolled seamless steel tube?
Hot rolled seamless tubes are divided into ordinary steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel tubes, stainless steel pipes, oil cracking pipes, geological steel pipes and other steel pipes, etc..
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:How seamless steel tube is formed?
Seamless steel tubes are formed by cold drawing and hot rolling.
