There are roughly four types of spiral pipes according to their uses: spiral pipes for drainage, spiral pipes for dredging, spiral pipes for piling, and spiral pipes for oil and gas.Spiral pipe for drainage: Material of spiral steel pipe for drainage: Q235A, Q23b, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9,
If the spiral steel pipe for water transportation is used to transport tap water or drinking water, the inner wall is usually made of IPN8710 non-toxic anti-corrosion coating, and the outer wall is made of epoxy coal tar pitch for anti-corrosion. Of course, it can also be used for inner and outer pl
As a terminal technical product of the steel pipe industry chain, anti-corrosion steel pipe has always occupied a very important position in the industry. In recent years, with the development and application of new anti-corrosion technologies for steel pipes, anti-corrosion steel pipes have become
①General boiler steel tubes are mainly used to manufacture water wall tubes, boiling water tubes, superheated steam tubes, superheated steam tubes for locomotive boilers, large and small smoke tubes, and arch brick tubes, etc.②High-pressure boiler steel tubes are mainly used to manufacture superheat
Welding method: When welding thick-walled steel pipes, first clean the oil, paint, water, rust, etc. of the weld joints, and then open the bevel according to the wall thickness. It is the gap between the products, which is generally 1-1.5 times the diameter of the welding rod or wire. If the groove
The welding of galvanized steel pipe should pay attention to:1. Galvanized steel pipes with a pipe diameter greater than 100mm should be connected by flanges or ferrule-type special pipe fittings.2. For the weld between galvanized steel pipe and flange, to ensure the welding quality, the weld joint
The variety of surface processing of stainless steel broadens its application field - different surface processing makes the surface of stainless steel different, making it unique in application. Surface finishing of stainless steel is important for many reasons in architectural applications.Corrosi
Large-diameter steel pipes are also called large-diameter galvanized steel pipes, which refer to welded steel pipes with hot-dip or electro-galvanized layers on the surface of large-diameter steel pipes. Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life.
Choose to purchase stainless steel pipes 1. Identify whether the material "304" is stamped on the surface of the pipe, and ask for the quality certificate and quality assurance certificate of the stainless steel pipe manufacturer.Choose to purchase stainless steel tube 2. Test with the acid reagent.
