Product Description:

1、Structure of Galvanized hollow section DIN-A21: 

Galvanized hollow section DIN-A21 is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable. we can provide you best service as we can, and we sure that we can give you satisfy sprice.

 

2、‍‍Main Features of the Galvanized hollow section DIN-A21: :

• High manufacturing accuracy

• High strength

Q:A333gr6 steel pipe and domestic material of the same?
The SA333 standard in ASME (cryogenic seamless and welded nominal steel tubes), so A333-6 is a representation of the United States, followed by many countries.
Q:SC15 what does galvanized steel pipe look like?
DN15 galvanized pipe, nominal diameter of 15mm
Q:What does GALV mean in a steel tube?
GALV is the abbreviation of English galvanized (Galvanized), which means galvanized steel pipe.
Q:What is lined pipe?
Pipe lining is a new technology in recent ten years of development, also called composite pipe conveying fluid with different needs, the use of different materials to make the durability of the pipeline inner wall and outer wall of pipeline, to ensure the purity of the fluid, pipeline adaptability, performance is greatly improved, more extensive use.
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.
Q:The plastic pipe and steel pipe difference
The steel plastic pipe is a general term, which includes plastic pipe, plastic lined pipe. Plastic pipe external coating, zinc coated and so on in Shanghai, Fujian, Portland, professional in this area
Q:Is the electric pipe used with steel pipe or PVC pipe?
Electric pipe laying is generally divided into the following circumstances:1) the explosion-proof area must be galvanized steel pipe and explosion proof flexible pipe (used for front end equipment connection);2) non explosion-proof area can use KBG pipe or PVC tube, the former is higher cost, but the installation is firm, the latter is low cost, easy to construction, and in the rain where it will not rust, but compared to the KBG pipe may be damaged.
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:Can seamless steel pipe and ordinary steel pipe be welded?
Steel pipe and seamless linking points, you said should refers to ordinary steel pipe joints, if only consider the butt welding problem, two kinds of steel can be welded. But the mechanical properties of the seamless steel pipe and tube with different, generally the main difference is the two kinds of steel can withstand the pressure of the former than the latter to be good.So if your project is seamed steel pipe can be, then the two pipe welding, welding and butt welding interface is completely no problem.
Q:Seamless steel pipe 8162 and 8163 what is the difference?
GB 8162 is the structure of the tube, there is no need for flaw detection, the use of mechanical processing, stents;
