ASTM A213 TP316L Stainless Steel U Bend Tubes Hydro Test Available

ASTM A213 / ASME SA213 TP304/TP316L/TP321 / TP321H /TP347H 3/4" , Stainless Steel U Bend Tube For Heating Application, 100% ET & HT

SA213 TP304 is a range of minimum wall thickness pipe series. We supply the SA 213 TP 304 Pipes in different types, shapes and sizes. The SA 213 Tp 304 Material consists of 18% chromium and carbon, manganese, phosphorus, sulfur, silicon and nickel in the composition. There is also the molybdenum, nitrogen, niobium and titanium addition in trace quantities. The SA 213 Tp 304 Density is lower than the ordinary 304 material. It is 7.8 grams per cubic centimeter. We offer ASTM A213 TP 304 for high temperature services. Our 304 Stainless Steel Tube components are of less absolute roughness which means they could be used in high precision equipment and applications.
