Product Description:

 

1Structure of Seamless Steel Pipe : 

Seamless pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell.  Historically seamless pipe was regarded as withstanding pressure better than other types, and was often more easily available than welded pipe.

 

2‍‍Main Features of the Seamless Steel Pipe:

• High manufacturing accuracy

• High strength

• Small inertia resistance

• Strong heat dissipation ability

• Good visual effect

• Reasonable price

Q:What is the production process of seamless steel tube?
The main production process for hot rolling seamless steel tube (the main inspection):Tube preparation and check delta to billet heating, heating, rolling, perforated pipe, steel pipe and heat treatment, diameter (minus) Delta to finished tube straightening, finishing and inspection of delta (nondestructive, physicochemical, Taiwan inspection and warehousing)
Q:What is the meaning of "DN" and "Phi" in the dimensioning of steel pipe diameter and how to apply the mark?
DN is a kind of Engineering path, not the actual value, due to the different standards, so the actual corresponding values is not the same; phi is refers to the actual value, the same national standard pipe inside the steel pipe, the actual value is the same, for example, GB/T8163 and GB GB fluid pipe spiral pipe and GBT/T9711.1 GB/T12459 the same nominal diameter corresponding to the actual value is the same as the actual value; and American Standard steel standard ANSI B 16.38 and ANSI B 16.9 standard American Standard fitting the same nominal correspondence is the same. If marked, the nominal diameter should be added DN, and the actual value can be omitted.
Q:What place must use galvanized steel pipe to make lighting line?
Galvanized pipe for pipeline laying construction and transformation of lighting, power, telephone, fire protection system in the engineering (made of galvanized steel), for laying, laying can be laid in the dark, the wall can also be installed on the ceiling.
Q:What is PE coated steel pipe? Seek explanation
PE coating on the inner wall of steel pipe steel pipe is covered with a layer of polyethylene plastic polymer, PE, polyethylene (Polyethylene of raised temperature is the abbreviation of resistance English), the scope of application of the general PE pipe water supply pipe to a temperature below 40 DEG C, cannot be used for hot water transmission pipeline.
Q:Heating system DN40 and DN32 welded steel pipe how to connect?
Is the wire: also called pipe thread connection, the malleable steel pipe fittings, malleable iron is the thread connection using DN40X32 diameter hoop.
Q:Fastener type steel pipe scaffold external parts name
Steel pipeScaffold steel pipe should adopt outer diameter 48mm and wall thickness 3.5mm welded steel pipe, also can use outer diameter 51mm and wall thickness 3.1mm welded steel pipe. For horizontal horizontal rods, the maximum length of steel pipe shall not be greater than 2m; other poles shall not be greater than 6.5m, and the maximum mass of each steel tube shall not exceed 25kg, so as to be suitable for manual handling.
Q:Which is more load-bearing, the same thickness of steel pipe and steel bar?
The same length, the same pipe diameter, the same material strength is hollow, the ratio of area of steel (solid), and the cyclical and slender radius smaller than the larger, so the longitudinal stability coefficient is smaller, three factors, two factors are weak in steel reinforced, another factor: strength, they are the same, no doubt, steel reinforced bearing less than.
Q:What's the difference between seamless steel pipe and welded pipe?
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 with the solid steel such as round steel, the steel tube is lighter in strength and is an economical section steel when the flexural strength and torsion strength are the same.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 circular parts, can improve the utilization rate of materials, simplify the manufacturing process, material saving and working hours, has been widely used to manufacture steel tube.
Q:Is the diameter of the steel tube indicated by the outer diameter by the wall thickness or by the inside diameter by the wall thickness?
For seamless steel pipes or nonferrous metal pipes, the outer diameter * wall thickness shall be marked".For example, 108 x 4 phi, Phi can be omitted. Some steel tubes in China, ISO and Japan adopt wall thickness to indicate the thickness of steel pipe. The method for the specification of such steel tubes is pipe outer diameter * wall thickness. For example, Phi 60.5 * 3.8.
Q:What does "steel pipe SC" mean?
SC (run in welded steel duitconSC is the line laying mode GB letter of wire is worn steel pipe laying (welded steel pipe, low pressure fluid) SC70 said the conductor by low pressure fluid DN70 welded steel pipe as protection pipe laying, DN70 said the nominal pipe diameter is 70mm, the nominal pipe diameter is 70mm (a series of values, the actual diameter slightly different).
