ASME SA249 TP316 Stainless Steel Welded Tubes Bright Annealed Mirror Polished
TONG CHUANG Special Steel has been engaged in the operation of seamless welded pipes and pipes of austenitic stainless steel， nickel alloy steel (Hastelloy， Monel， Inconel， Inconel) for more than 25 years， and annual sales of more than 80，000 tons of steel pipes and pipes. Our customers have covered more than 45 countries including the United States， Canada， Italy， the United Kingdom， Germany， Chile， Colombia， Saudi Arabia， South Korea， Singapore， Australia， Poland， and France.
Compared with traditionally used chromium-nickel steel， marine grade SA 249 Tp316 has excellent corrosion resistance， especially during exposure to corrosive compounds. One reason the stainless steel 316 Erw is considered superior to the chromium-nickel steel grade is the addition of chromium to its alloy. Although similar to austenitic alloy 304， 316 stainless steel welded pipes are much more resistant to sea water and saline solutions. Therefore， welding 316 stainless steel pipe is synonymous with offshore engineering applications.
In addition， in addition to solutions containing sulfuric acid， ASTM A249 TP316 tubes can also tolerate halides such as chloride， bromide， and iodide. ASTM A249 TP316 welded boiler tubes are also resistant to fatty acids at high temperature settings. In addition， SA-249 TP316 will not lose its mechanical properties when used in a wide temperature range. Because the alloy is non-toxic， A249 TP316 welded pipe is usually used in industries with zero tolerance for pollution. For example， the textile， pharmaceutical， and food and beverage industries prefer to use ASME SA 249 TP316 because it has no pollution characteristics.
