ASTM A213 TP304 Stainless Steel Seamless Tube Pickled For Heat Exchanger And Boiler
TONG CHUANG GROUP is one of the big manufacturers of high quality ASTM A213 / ASME SA213 TP 304/304L pipes. ASTM A213 TP304 Specification for Seamless Ferritic and Austenitic Alloy Steel Boiler， Heat Exchanger， and Superheater Tubes. ASTM A213 seamless tubes are mainly used as superheater， boiler， heat exchanger tubes. ASME SA213 TP304 pipe is made from austenitic grades with 2% to 3% molybdenum added to further improve corrosion resistance. ASTM A213 TP304 Tubing sizes and thicknesses are typically supplied to their specifications from 1/8 in. [3.2 mm] ID to 5 in. [127 mm] OD with a minimum wall thickness of 0.015 to 0.500 in [0.4 to 12.7 mm] (inclusive of )thickness. ASTM A213 UNS S30400 tubing in other diameters may be supplied provided that such tubing meets all other requirements of this specification.
Large Diameter ASTM A213 Stainless Steel 304L is used in a variety of applications and industries including food and beverage processing， petrochemical and construction. ASTM A213 Stainless Steel Tube includes ASTM A213 TP304L Stainless Steel Square Tube， ASTM A213 TP304L Stainless Steel Oval Tube， ASTM A213 TP304L Stainless Steel Rectangular Tube， ASTM A213 TP304L Heat Exchanger Tube， ASTM A213 TP304L Stainless Steel Condenser Tube， ASTM A213 TP304L Stainless Steel Superheater Tube and ASTM A213 TP304L Stainless Steel Rectangular Tube A213 TP304L stainless steel round tube， custom shapes and sizes available. ASTM A213 TP304L heat exchange tubes have excellent corrosion resistance at normal temperature and normal atmospheric conditions and can withstand some natural acids， which is why this grade is often used in the food and beverage processing industry.
