CHEMICAL COMPOSITION (%)
- Q:What kinds of steel pipe are divided into?
- According to the weld shape can be divided into longitudinal welded pipe and spiral welded pipeStraight welded pipe: the production process is simple, high production efficiency, low cost, rapid developmentSpiral welded pipe: strength ratio of longitudinal welded pipe is high, with a narrow billet production of large diameter pipe, also can use the blank production of the width of the same diameter of different pipe. But with the same length of straight pipe, weld length of 30~100%, and the production rate is low. Therefore, the smaller diameter pipe most used straight large diameter pipe welding, mostly using spiral welding.Dividedagain general welded pipe, galvanized pipe, blowing pipe, wire tube, pipe metric, roller tube, deep well pump, tube for automobile, transformer tube, welding, welding of thin-walled tube shaped tube and spiral welded pipe.General general pipe: pipe used for conveying the low-pressure fluid. Q195A, Q215A and Q235A made of steel. Also can be used for easy welding of mild steel. The other pipe to conduct water pressure, bending and flattening test, have certain requirements on the surface quality, usually the delivery length is 4-10m, often requires a fixed length (or size) of delivery. The specifications of welded pipe with nominal diameter (mm or inches) nominal diameter and different pipe wall thickness, according to the provisions of general steel and thicker steel two, steel pipe end is divided according to form of threaded and non threaded two.
- Q:Seamless steel tube with the tube with what is the difference?
- At present there are some seamed steel pipe seamless treatment tube, it is the weld annealing treatment, eliminate the residual stress of the weld, the weld and base material, the pressure range of basic and seamless pipe is. May also consider the use of.
- Q:How to distinguish seamless pipe and welded pipe?
- If it is seamless pipe, the port can be seen inside and outside the pipe there is no welding meat exists, and even if the welding pipe welding processing, the pipe weld is very easy to observe.
- Q:What does GALV mean in a steel tube?
- Steel pipe is not only used to transport fluid and powder solid, exchange heat energy, and manufacture mechanical parts and containers, but also is an economic steel. It can reduce weight and save 20 to 40% of metal by using steel pipe to make building structure, network frame, prop and mechanical support. Moreover, it can realize factory mechanization construction. Using steel pipe to manufacture road bridge can not only save steel, simplify construction, but also greatly reduce the area of coating protective layer, save investment and maintenance cost.
- Q:What are the uses of seamless steel tubes?
- A large number of pipes used for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials.
- Q:Material of welded steel pipe
- GB/T3091-1993 (galvanized steel pipe for low pressure fluid delivery). Mainly used to transport water, gas, air, oil and heating, hot water or steam, etc. generally lower pressure fluid and other use tube. Its representative material is Q235 grade a steel.
- Q:How to identify stainless steel pipe and steel pipe?
- Stainless steel (Stainless Steel) is referred to as the stainless steel, the resistance of air, steam, water and other weak corrosive medium or with stainless steel known as stainless steel; while the resistance to chemical corrosion (acid, alkali and salt chemical etching) corrosion of steel called acid resistant steel. Because of the difference in the chemical composition of the two, and make their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical medium corrosion, and acid resistant steel are generally stainless steel.
- Q:304 stainless steel tube with the diameter of 25*2-3 is what mean
- 304 stainless steel tube with the diameter of 25*2-3 said: material for 304 (the equivalent of the American brand, Chinese numbered S30408 stainless steel or 06Cr19Ni10 stainless steel), diameter (OD) for 25mm, for the seamless steel pipe wall thickness of 2 to 3mm.
- 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 does "HBB" glass steel pipe mean?
- Good water resistance, can be used for a long time in wet or water, and the ordinary composite is not water resistant, can only be used in dry environment.Heat resistance, fire resistance is superior to epoxy, glass fiber reinforced plastics and plastic and other materials. It can be used at 130 degrees for a long time, and not burned in case of fire.The utility model has the advantages of insulation, corrosion prevention, no rust, long service life, etc.. Generally up to 50 years, without maintenance.Simple and convenient installation and construction, because this product is light weight, high strength, laying construction method can properly solve the excavation due to road construction, exposed for a long time, prominent problems of city traffic, to achieve the excavation backfill pavement, buried at night, can normal traffic during the day.
Perfect detection system, our physical & chemical laboratory is equipped with test facilities included spectrum detection and metallographic analysis etc. The company has successively passed ISO9000 quality system, the American Petroleum Institute API, and also earned the environment healthy license, national special equipment manufacturing license.
