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:What is the single length of galvanized steel pipe?
Hot dip galvanized steel pipe is widely used in fire, power and highway.
Q:25 of the steel pipe with 6 in charge of what is the difference?
25 of the steel pipe with 6 in charge of the difference:25 of the steel pipe refers to the DN25 tube, the outer diameter of 25mm; 6, in charge of refers to DN20 steel pipe, the outer diameter is 20mm.
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:How can galvanized steel tubes be painted on the surface?
Suitable for galvanized base material (antirust primer), epoxy zinc yellow primer (double component), epoxy ester zinc yellow primer.Pretreatment of galvanized sheet when brushing:1, conditional, you can zinc plating phosphating treatment, or first spray a layer of phosphating primer.2, or smooth zinc plating surface sweeping treatment.3, the galvanized workpiece, galvanized pipe surface with solvent (that is, epoxy zinc yellow primer, thinner) wipe, in order to remove the workpiece crude oil protective layer, and increase cleanliness.4, two-component epoxy zinc yellow primer: in strict accordance with the proportion of paint and curing agent paint, and aging 30 minutes later, modulation suitable construction viscosity, you can spray.One component epoxy ester primer: zinc yellow construction viscosity suitable to construction of modulation, the correct construction method.
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 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 relatively alloy steel. Its carbon content is higher than alloy steel, and 20# steel is one kind of carbon steel.
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 is the difference between steel pipe and round steel?
Making ring parts with steel tubes can improve data application rate, simplify manufacturing process, save data and work hours, such as rolling bearings, rings, Jack sleeves, etc., and have been widely used in steel pipe manufacture.
Q:Is hot dipped plastic pipe steel?
The characteristics of hot dipped plastic pipe are:1., hot dipped plastic pipe superior anti-static performance: through the formula to add antistatic agent, so that its internal and external surface resistance value reached and exceeded the national industry standards.2., such as the use of plastic raw materials, add flame retardants. The flame retardant performance index conforms to the national standard, and the steel plastic composite structure has better flame retardance than the pure plastic pipe material, and is suitable for underground inflammable, explosive and other places.3. hot dip coating steel strong adhesion: steel surface after special treatment, curing, coating adhesion is greater than or equal to 30N/10mm.4., dense internal and external resin layer: coating thickness of more than 0.5 mm, no pinholes, with excellent corrosion resistance.The mechanical properties of plastic steel pipe superior 5. hot dip: can withstand the harsh conditions of use: coating steel has good toughness, high mechanical strength, impact bending and other foreign influence, has a strong bearing capacity, has better performance than other mine plastic pipes.6. hot dip steel corrosion and fouling, the fluid resistance is small: corrosion and fouling, especially suitable for the underground conveying high sulfur water and transport of calcium and magnesium plasma water, save the maintenance cost, service life is much higher than that of the other pipe, high economic benefit.7. self lubrication: smooth wall, no fouling, small transmission resistance, under the same conditions, can improve the transport capacity of 30%.8. convenient and reliable connectionThe utility model completely overcomes the defects of the difficult connection of the pure plastic mining materials, and can be connected with the underground steel pipe and the valve by using flanges, fast couplings, etc., and has strong interchangeability.
