Product Description:

1Structure of Seamless Pipe ASTM A106/53: 

Rectanglar Hollow section

1) Dimensions: 10 x 10mm - 400 x 400mm
2) Thickness: 0.45 - 16MM
3) Material:Q235,Q345 S355

 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 much is the wall thickness standard of building 48?
According to the "construction of fastener type steel pipe scaffold safety technical specifications JGJ130-2011" stipulates that the specification of steel pipe should be Phi 48.3 * 3.6, that is, wall thickness is 3.6mm.
Q:How to distinguish seamless pipe and welded pipe?
If it is seamless pipe, the port can be seen inside and outside the pipe there is no welding meat exists, and even if the welding pipe welding processing, the pipe weld is very easy to observe.
Q:What does "steel pipe SC" mean?
DN100 and "SCH80" refer to the outer diameter and the wall thickness of the steel pipe;
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:Seamless steel tube with the tube with what is the difference?
At present there are some seamed steel pipe seamless treatment tube, it is the weld annealing treatment, eliminate the residual stress of the weld, the weld and base material, the pressure range of basic and seamless pipe is. May also consider the use of.
Q:Can galvanized steel tubes simmer?
Galvanized steel pipe can simmer bending.Is a set of bending bending bending die, no matter what kind of equipment, most are used in pipe, mainly used for oil and gas, infusion, more plays an important role in aircraft and engine.
Q:What time what time for gas pipeline steel pipe PE pipe
PE pipe is suitable for medium voltage and low voltage 0.4MPa below the pressure pipe wall thickness. According to the different pressure is not the same, so the steel tube can be used for high pressure.
Q:What quota should be installed for heating seamless steel 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.
Q:45 and 316 which steel tubes are of high hardness?
No. 45 steel for high-quality carbon structural steel, the hardness is not high machining, used to make the template, mould studs, guide column, subject to heat treatment. 45 steel quenched and tempered hardness between HRC20~HRC30; 45 steel quenching hardness between HRC55~58, the limit value of up to HRC62.
Q:How seamless steel tube is formed?
Overview of two kinds of steel pipe process:1, cold drawing (rolling) seamless steel pipe: round tube to heating to perforation, annealing, pickling, leading to oil (copper), multi pass drawing (Leng Zha), the blank pipe, heat treatment, straightening, pressure test (testing), marking and warehousing.2. Hot rolling (extrusion seamless steel tube): round tube billet, heating, piercing, three roll cross rolling, rolling or extrusion, removal of pipe, sizing, reducing (diameter or reducing), cooling, blank tube, straightening, water pressure test (or flaw detection), marking and warehousing.
