SS 304/304L Cast Valves | Petroleum Corrosion Data

Petroleum Corrosion Resistance Data Stainless steel 304/304L cast valves denote valves with body and bonnet made of ASTM A351 Gr. CF8 or Gr. CF3 high-alloy austenitic castings. Both CF8 (304) and CF3 (304L) have the same nominal composition 18Cr-8Ni but different UNS designation, J92600 and J92500, respectively. The main difference is that CF3 has much lower carbon content. Another conventional …

Postweld Heat Treatment for ASTM A335 P11 pipes

Construction Codes & Significance Seamless pipes made of low-alloy steel ASTM A335 Grade P11 can be used for power piping (ASME B31.1) or process piping (ASME B31.3) at elevated temperatures. After joining the two ASTM A335 P11 pipes together by a welding process, postweld heat treatment (PWHT) is required. The PWHT is used to avert or relieve the detrimental effects …

ASTM A335 P11 Used for ASME B31.1 Power Piping

ASME B31.1 is the Code for power piping, which is typically piping typically found in electric power generating stations, in industrial and institutional plants, geothermal heating systems, and central and district heating and cooling systems. It has designated ASTM A335 Gr. P11 seamless pipes as the listed material in Table A-2. The ASTM A335 P11 has the nominal chemical composition …

ASTM A192 Tubes Used for Sugar Cane Bagasse Boilers

The cane sugar is usually extracted from sugar cane in a process that generates huge amount of bagasse. The bagasse is the dry pulpy fibrous residue that remains after sugarcane is crushed to extract their juice. So in a word, it is bio-waste. Fortunately, it can be used as a biofuel for the production of heat, energy, and electricity, and …

ASTM A179 Tubes Used for Amine Heat Exchangers & Coolers

Amine solutions are widely used in desulphurization and decarbonization process in fossil-fueled thermal plant, natural gas purification plant, coal chemical industry, and ammonia industry. The most common facilities are lean/rich amine heat exchangers and lean amine coolers, the tube pass of which is usually constructed by ASTM A179 seamless tubes. These tubes are made from ASTM A179 low carbon steel …
