304, 304L, 316, 316L are the four most popular austenitic grades of stainless steel piping which provide excellent corrosion resistance.
Material is stocked in the annealed and pickled, bright annealed, mill finish and polished conditions.
How to select welded stainless steel pipe?
The quality of steel pipe is mainly measured by the same material, standard and welding quality.
According to its own structural characteristics, stainless steel straight welded pipe has two main uses:
First, it is used to transport liquids, such as water supply and drainage;
Secondly, based on the superior anti-corrosion performance of welded straight seam stainless steel pipe, it can also be used to transport gas, oil and other chemicals.
We use SUS304 and SUS316 materials, superior performance, products with good pressure resistance, corrosion resistance, health and environmental protection. The products meet the requirements of ASTM A554, ASTM A312, EN10312, JIS G3448 and other standards. It is widely used in cold water heating system of industrial and civil buildings, heat exchange system and pipeline system of environmental protection, energy and petrochemical industry. From the acquisition of raw materials, from the production process to production testing, we have a complete process. Our products are widely used in hotels, natural gas, municipal, fire, food, cruise, construction and other projects.
