All the tubes and pipes that are manufactured for industrial use are designed according to the international standards which defined their quality. These standards also ensure that the product is reliable and are made according to the industrial’s requirements. The commercial tube such as Stainless Steel 321/321H Tubes are highly important and beneficial for various industries therefore it is essential that the manufacture maintain its product quality. They should have high strength and tolerance to sustain in different working environment. The industrial working environment is harsh and thus they should be able to withstand in all the weather while serving its best to the industry.
The SS 321/321H Welded Tubes should have zero defects. These tubes are made of austenitic chromium nickel alloy. However, titanium is also added while manufacturing the tubes as it give them strength to withstand in elevated temperature environments.
The tubes have specified dimensions and range which make them suitable for different applications. For an example, the tube range may vary from 6.35mm OD – 100.6mmOD. Its length can go up to 30 meters and in other cases the length may be more than 30 meters. The pipe specification can be ASTM A4213 or ASTM SA4213. These pipes also vary in shape where square, rectangle, round, U shape, coil shape and hydraulic and honed tubes are available.
This SS 321/321H Seamless Tubes have standards as said above so they are. SS 321- UNS S32100 and WERKSTOFF NR 1.4541, for SS321 H- UNS S32109 and WERKSTOFF NR 1.4878 standards. These tubes are varying in chemical composition where the composition is set according to the requirements.
