Product Description:

1Structure of Hot Rolled Seamless Steel pipe Made in China from CNBM: 

Seamless pipe 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. Historically seamless pipe was regarded as withstanding pressure better than other types, and was often more easily available than welded pipe. 

 

2‍‍Main Features of Hot Rolled Seamless Steel pipe Made in China from CNBM:

• High manufacturing accuracy

• High strength

• Small inertia resistance

• Strong heat dissipation ability

• Good visual effect

Q:What is the difference between the stainless steel pipe welded pipe and seamless pipe?
Concentricity: seamless tube manufacturing process is the temperature of 2200 degrees F in stainless steel billet stamping a hole, at this high temperature, tool steel by stamping and drawing become soft and spiral form from the hole. Thus, the wall thickness of the pipeline is uneven and the eccentricity is high. Thus ASTM allows seamless pipe wall thickness ratio of the wall thickness difference of seamed tube. Through the seamed tube cold rolling plate precision (per roll width is 4-5 feet) made. These cold rolled plates usually have a maximum wall thickness of 0.002 inches. The steel plate is cut into a width of PI D, in which D is the outer diameter of the pipe. Tube wall thickness tolerance is very small, and the entire circumference of the wall thickness is very uniform.
Q:What are the lengths of scaffold steel tubes?
Used to build scaffolding of steel pipes in general have two kinds, an outer diameter 48mm, wall thickness 3.5mm; another kind of outer diameter 51mm, wall thickness 3mm; according to its location and role of different, can be divided into vertical pole, horizontal rod, sweeping rod, etc.. According to the technical specification for construction of steel tubular scaffold with couplers, JGJ 130 - 2011[1]. The scaffolding steel pipe should be specified with the current national standard "GB/T13793" or "straight seam welded steel pipe welded steel pipe for low pressure liquid delivery" GB/T3091 Q235 ordinary steel pipe; steel pipe steel quality should meet the requirements of current national standard grade Q235 steel "carbon structural steel" in GB/T700. The scaffold pipe shall be made of a diameter of 48.3 * 3.6 steel tubes. The maximum mass of each steel tube shall not be greater than 25.8kg.
Q:How can galvanized steel tubes be painted on the surface?
Galvanized parts are nonferrous metals, ferrous metals are black, all metal adhesion is poor;
Q:What is the weight of hot galvanized steel tubes? DN150 4mm wall thickness
DN150 4mm wall thickness welded steel pipe theoretical weight is 16.21kg/m, galvanized steel pipe should be multiplied by the weight coefficient after galvanizing, C, DN150, wall thickness of 4mm, C=1.032, DN150, theoretical weight and wall thickness of 4mm galvanized steel is 1.02*16.21=16.7287kg/m = 16.73kg/m.
Q:Welded and seamless steel pipe how to distinguish?
Different uses:Mainly used for seamless pipe or structural parts of the transmission fluid, mainly used in machinery industry, and seamed steel pipe is mainly used in the construction industry, such as water, gas, compressed air and low pressure fluid. But seamless steel tubes are used in all pressure pipes.
Q:What is the difference between galvanized iron pipe and galvanized steel pipe? Or called different, in fact, is referred to as galvanized pipe?
Different materials, cast iron, steel seamless steel pipe; the different production process, cast iron is hot metal casting, steel rolling mill of seamless steel tube is through processing, different performance indexes, ductile iron diameter, wall thickness, crisp texture, relatively heavy, can be made of seamless steel pipe diameter is very small, the wall is very thin, good toughness, light. Cast iron, cheap, but the bottom of the strength, can only be used in low pressure occasions.
Q:How to descaling galvanized steel pipe?
Is red rust or white rust, red rust is the base material rust, white rust is Zinc Coating Rust
Q:How to distinguish between steel pipe and spiral pipe material?
The alloy tube can be divided into: low alloy pipe, alloy pipe structure, high alloy tube, high strength tube. Bearing tube, heat resistant acid resistant stainless pipe, precision alloy (such as cutting alloy) pipe, high temperature alloy tube, etc..
Q:Which is cheaper, angle iron or steel pipe?
Steel tube (Steel pipe) production technology development began in the bicycle manufacturing industry, the rise of the early nineteenth Century during the oil development, the two world war ships, boilers, aircraft manufacturing, manufacturing of power boiler after the Second World War, the development of chemical industry of petroleum and natural gas drilling and transportation, will effectively promote the the yield and quality of varieties, the development of steel tube industry.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:Are galvanized steel tubes the same as degaussing steel tubes?
And the method of magnetic field created by means of electromagnets or permanent magnets. For analysis of residual magnetism, see table (1), select the demagnetizing method and system in combination with the conditions of the construction site (for example, given equipment, etc.).
