ASME SB677 – Extremely corrosive resistanceĪSME SB677 specification covers the UNS N08904 (904L), UNS N08925, UNS N08926 (alloy 926), in seamless, of cold-drawn, and hot finished steel pipe and steel tube for the extremely corrosive services. The ASTM A269 covers the stainless steel tubes for common application in seamless and welded. The ASTM A213 covers the seamless ferric carbon steel and austenitic alloy stainless steel tube, applied for boiler, superheater, and heat-exchanger steel tubes. Permitted Tolerance in Wall Thickness in ASTM A312ĭ = Ordered Outside Diameter ASTM A213 stainless tubing for boiler, heat exhanger Chemical Composition for ASTM A312 TP304 and TP316
Fluorosilicic /acid reactor phosphoric acid plant Chlorate Crystallizer in the production of fertilizer Ventilation system in pharmaceutical factory Solvent recovery filter, condenser, pipeline Bleaching equipment and filter in the pulp and paper industry pipelines and water collecting system in offshore platforms multi-stage flash distillation, low-temperature multi effect desalination seawater condenser for power plant and so on. stainless steel pipe and tube is widely in sulfuric acid storage tank in the phosphate fertilizer industries. The ASTM A312 standard specification for seamless, welded, and heavy cold worked austenitic stainless steel pipes. Common standards explanationĪSME SB677 ASTM A312 – For high temperature and general corrosive Octal offers super austenitic stainless steel pipe and tube in different material standards and grades. According by manufacturing process can divided into following basic types: hot-rolled, extrusion, cold-circular, hexagonal, equilateral triangle, octagonal and other special-shaped stainless steel pipe This kind of pipes divide into: stainless steel seamless pipes and stainless welded pipes. Also used to produce all kinds of conventional weapons, barrel, shells and so on. In additional, when twisting and anti-twist intensity is equal, stainless steel is more lighter, so it used in equipment parts and projects structural.
Stainless steel pipe and tube has been widely used in oil, chemical industry, medical, food, light industry, equipment and apparatus and structural parts etc. Stainless steel pipe is a kind of hollow and longitude steel, economic steel section is round shape. Stainless steel pipe added with Ni and Cr chemical elements to provide better corrossion resistance for to use in different environment, common use material 304/L and 316/L, standard in ASTM A312, A213, A270 and etc.
