Product Description:

 

1Structure of Seamless Pipe ASTM A106/53: 

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 the Seamless Pipe ASTM A106/53:

• High manufacturing accuracy

• High strength

• Small inertia resistance

• Strong heat dissipation ability

• Good visual effect

• Reasonable price

Q:How to distinguish seamless pipe and welded pipe?
The way to distinguish seamless pipes and welded pipes is to see if there is weld marks on the port.
Q:What's the use of steel pipe?
No other type of steel can replace the steel tube entirely, but the steel tube can take the place of some sections and bars. Steel pipe is very important to the development of national economy and the improvement of human life quality, much better than other steel products. From the people's daily utensils, furniture, water supply and drainage, gas supply, ventilation and heating facilities to all kinds of agricultural machinery equipment manufacturing, underground resources development, national defense and space use guns, bullets, missiles, rockets and so cannot do without steel.
Q:Heating system DN40 and DN32 welded steel pipe how to connect?
As for the flange connection: low pressure pipeline is generally not used in this way, can be divided into threaded flanges and flange welding flange, and the flange connecting pipes of different diameters, only the welded flange to diameter, said in a low pressure pipeline which has low pressure pipe connection make an unnecessary move, this is not much, but there are also people with non the standard flange for connecting different pipe diameter, which is not consistent with the technical specification!
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: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?
Carbon steel is actually relative to alloy steel, mainly carbon content, and 20# seamless steel is carbon steel! In addition, there are stainless steel, stainless steel is considered a kind of alloy steel, but the processing is not the same, the performance is not the same, good looking outside!The description of the material in alloy steel is actually the content of the metal elements in the steel (usually the percentage number).
Q:Which is better, galvanized steel pipe or stainless steel?
Most of the use requirements are to maintain the original appearance of the building for a long time. In determining the type of stainless steel to be chosen, the main consideration is the aesthetic standards required, the corrosivity of the atmosphere in the area, and the cleaning system to be adopted. However, other applications increasingly seek only structural integrity or watertightness. For example, the roof and side walls of industrial buildings. In these applications, the construction cost of the owner may be more important than the aesthetic, the surface is not very clean can also. The use of 304 stainless steel in a dry indoor environment is quite effective.
Q:What's the difference between stainless steel seamless tube and stainless steel welded pipe?
Stainless steel welded pipe is also a hollow section of steel, but it is welded through the plate into the steel pipe, so there is a welded steel pipe welding gap.
Q:How to calculate the maximum bending stress of steel pipe? Is there a list of the maximum flexural normal stresses for steel pipes of different materials and diameters?
The maximum flexural normal stress is calculated as: Sigma =M/ (gamma x*Wnx).Of which: M is the maximum bending moment of the steel tube;Gamma X - the plastic development coefficient of the cross section; for the cross section of the steel tube, 1.15,
Q:Are metal spiral tubes the same as metal bellows?
The corrugated pipe is extruded by the extruder, the winding pipe is wound in a circle, and the prestressed metal corrugated pipe is a reserved channel.
Q:Are there specifications for scaffold steel pipe with 48mm * 3.2mm?
Scaffold tubes are our name for materials used to build scaffolding, because most scaffolding uses tubular bamboo or steel tubing. Bamboo and other bamboo is for a long time in the use of the scaffolding tube, but due to lack of safety and durability, now only in rural and urban area construction is lagging behind some of the home building small building has been used. The modernization construction, the most commonly used type of scaffolding pipe is steel pipe, the scaffolding should not only meet the demand of workers, but also to meet the characteristics of scaffolding firm and durable, so tough hard steel is the best choice. The selected steel pipe generally requires smooth surface, no cracks, no bending, no rust, and meet the relevant national standards.
