CHEMICAL COMPOSITION (%)
- Q:What's the actual size of the DN25?
- 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:SC15 what does galvanized steel pipe look like?
- DN15 galvanized pipe, nominal diameter of 15mm
- Q:What's the material of Q325 steel pipe?
- Plain carbon structural steelIt's a kind of steel material. Q stands for the yield of this material, and the latter 325 means the yield value of this material, at around 325. And the yield value will decrease as the thickness of the material increases.
- Q:What's the difference between hot dip galvanizing and cold galvanizing? Which kind of galvanizing method is good?
- Cold galvanizing refers to the zinc plating, the coating is thinner, corrosion resistance is slightly worse, variable color. Environmental pollution.Hot dip galvanized by molten zinc ingots, the coating thickness can be adjusted, good corrosion resistance, and subsequent passivation, can be used for outdoor rust, long service life, some up to 20 years.
- 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:What are the advantages of PVC pipe and galvanized steel pipe?
- The steel plastic composite pipe is a product made of two different materials, steel and plastic, and the coefficient of linear expansion between them is quite different. The company is using a new plastic special plastic steel plastic composite pipe company and Nanjing University jointly developed, the polyethylene matrix, adding more than twenty kinds of new materials inside, greatly reduce the plastic coefficient of linear expansion, so as to ensure the steel and plastic composite materials in the reliability of the.
- Q:How long are the seamless tubes? Are they six meters long?
- 6 meters of a root in general need to be customized, seamless tubes are mostly seven meters above the variable foot
- Q:Is there any difference between HFW steel pipe and ERW steel pipe?
- High frequency welding uses the skin effect to concentrate the energy of the high frequency current on the surface of the workpiece, and uses the proximity effect to control the position and range of the high frequency current flow path. The speed of the current is very fast, it can in a short period of time will be adjacent to the edge of the steel plate heating, melting, and through the extrusion docking, each has its own advantages, but also each has its own shortcomings. Generally according to specific circumstances, specific analysis of specific choices.
- Q:What is the size of seamless steel tube DN150?
- Seamless steel pipe having a hollow cross section, used as a conduit for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials. Compared withsteel and roundsteelinsolid, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, the bicycle frame and steel construction with scaffold with steel pipe manufacturing ring parts can be improved the utilization rate of materials, simplify the manufacturing process, material saving and working hours, has been widely used to manufacture steel tube.
- 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.
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.
