JIS G3459 SUS 316 TP Introduce
JIS G3459 SUS 316 TP pipes specified in this standard generally fall under the category of stainless steel pipes. The material that is used for the manufacture of these pipes is the stainless steel. Stainless steel is a material comprised of various mixtures of iron and other elements such as nickel, titanium, chromium, and carbon. These elements give stainless steel its remarkable properties such as corrosion resistance, durability, and strength. It is because of these properties that stainless steel is used in a wide range of applications and products, including kitchen appliances, automobiles, and industrial machinery. The stainless steel pipes conforming to JIS G3459 SUS 316 TP are divided into different categories depending on their outer diameter, wall thickness, length and form. The categories are as follows, 1) Light Wall Pipes, 2) Medium Wall Pipes, 3) Thick Wall Pipes, 4) Long Length and 5) Special Lengths. These pipes could also be manufactured in two different forms i.e. seamless and welded.
