Precision Tubes Meaning
The precision stainless steel tube is a hollow strip of steel.
A large number of pipes used to transport fluids, such as petroleum, natural gas, water, gas, steam, and the like.
In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures.
Also used to produce a variety of conventional weapons, barrels, shells and so on.
Stainless steel precision tube generally refers to precision stainless steel tube
Precision stainless steel pipe is safe, reliable, environmentally friendly and economical.
The thin wall of the pipe and the successful development of a new reliable, simple and convenient connection method have the advantage that it has more irreplaceable other pipes.
There will be more and more applications in the project, and the use will become more and more popular, and the prospects are promising.
Classification

Shaped precision stainless steel tube manufactured by JawaySteel
Characteristics
Shaped precision stainless steel tubes generally have two or more uneven irregular bores.
Moreover, the cross section is usually disordered due to the asymmetry, so that the flow velocity distribution unevenness is likely to occur in the cross section.
In addition, the wall thickness is also uneven, and sometimes the wall thickness difference can be ten times or even tens of times, resulting in different extrusion swells and different residuals.
Unlike ordinary shaped tubes, precision shaped tubes are superior in precision and brightness, so they are favored by various industries.
