Product Description:

1Structure of Seamless Pipe: 

We are company that have many years experience and professional manager team and engineer team and sales team, sure we will provide you high quality of pipe and professioanl service.

Seamless pipe possesses a hollow section and without seam around the strip steel. It is made with solid bar or steel ingot by perforating machine. As the facture process does not include any welding, seamless pipes are considered to be stronger and more durable. Generally speaking, seamless pipe has better pressure resistance and security than other classifications, and was usually more easily available than welded pipe.

High working accuracy

High strength

Small inertia resistance

Strong therming dissipine ability

Good appearance

Reasonble price

Q:What kind of argon arc welding wire is used for 16Mn steel pipe?
JB/T4709 recommends H10MnSi, but H10MnSi allows a lower value of strength of 430MPa, which does not match the parent material. I think American Standard is selected according to the selection of welding wire ER70S-6 GB ER50-6 wire can guarantee the equivalent strength of parent materials, and Si, Mn content can also guarantee the deoxidation effect, the weld joint is not easy to produce pores.
Q:What does carbon seamless steel pipe mean? What is the difference between a seamless 20# and an ordinary one? What is it used in detail?
In general, steel is divided into two groups according to their chemical composition: carbon steel and alloy steel;(1): carbon steel low carbon steel (C = 0.25%); carbon steel (0.25% < C < 0.60%); high carbon steel (C = 0.60%)(2): alloy steel, low alloy steel (alloy is less than or equal to 5%); in steel (5% < < 10% alloy; high alloy steel (alloy) = 10%)Carbon seamless steel tubes are mostly pipes for mechanical engineering structures and pipes for conveying fluids.
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:DN80 seamless steel tube, what is the standard thickness?
Commonly used DN80 seamless steel pipe caliber should be 89mm*4mm.
Q:Are galvanized steel tubes the same as degaussing steel tubes?
Also known as galvanized steel pipe, hot galvanized and galvanized two kinds, hot galvanized, zinc coating thickness, with uniform coating, adhesion, and long service life. The cost of galvanizing is low, the surface is not very smooth, and the corrosion resistance of itself is much worse than that of galvanized pipe.
Q:What's the difference between round and round tubes?
Round steel is solid and round tubes are hollow
Q:The outer circle of a seamless steel pipe 50 head into the outer circle of the 40 to close
Cold drawn steel tube and cold rolled steel pipe mill is a complete set of equipment which combines cold rolling, cold drawing, cold rolling and cold drawing to produce pipes. It is a unit for deep processing of hot-rolled pipes or welded pipes.
Q:How many meters per ton of steel tube?
General scaffolding tube diameter 40mm, specifications specify wall thickness of 3.5mm, the actual wall thickness of 3.2 - 3.4mm.The theoretical weight per meter is 3.85kg and the wall thickness is 3mm.Hence a ton of steel is about 260m.
Q:What is a tight steel tube?
JDG pipe is the replacement of traditional PVC and SC pipes and other traditional wire conduits. It is a breakthrough in the field of building electrical field using new materials and technologies. The JDG pipe adopts the cross connecting ground wire of galvanized steel pipe and thin-wall steel pipe, overcomes the defects of complicated construction and large construction loss of common metal pipe, and solves the problems of poor fire resistance and difficult grounding of PVC pipe. Because the JDG pipe material is more expensive than the ordinary pipe material, it is more used in the construction, such as comprehensive wiring, fire protection wiring and so on.
Q:What does "steel pipe SC" mean?
DN100 and "SCH80" refer to the outer diameter and the wall thickness of the steel pipe;
