(EXCERPTS FROM BOILER, PRESSURE VESSEL AND PIPING CODES AND STANDARDS) The material for forcedcirculation boilers, boilers with no fixed steam and water line, and hightemperature water boilers PG5.5 The use of austenitic alloy steel is permitted for boiler pressure parts that are steam touched in normal operation. 13CrMo4-5, 10CrMo9-10, 14MoV6-3, P91, P92 - boiler steelBoiler, pressure vessel, and heat exchanger steels for power industry - characteristics and application. Also known as alloy and carbon steel for high temperature operation or as a steel for power industry, used in environments with operating temperatures up to 600 , where the condition is to maintain similar strengths at room temperature.
ASMEs Boiler and Pressure Vessel Code (BPVC) 2013 Pressure Vessels Division 2 requirements on materials, design, and nondestructive examination are more rigorous than in Division 1; however, higher design stress intensify values are permitted. These rules may also apply to human occupancy pressure vessels typically in the diving industry.

After all those years of developing, ANSON STEEL has become one leading boiler and pressure vessel steel supplier in China, with the development of pressure vessel equipments, a wide variety steel types and grades of steel plates are now being produced. ANSON STEEL is an ISO 9001 registered company, our partner steel mills have other certifications for steel grades of ASTM/ASME, DIN, JIS, GB. Blowdown pipe erosion - Boiler and Pressure Vessel Have a surface blowndown line 1" in dia. It tees into a 2" forged steel tee. Boiler pressure is about 100 psi. The eroded spot is directly above the tee and the reducer from 1" to 2" is about 6" prior to the tee. Downstream it leads to a drain. The failure occurred after approximately 18 months. Boiler Quality Steel Plates / BQ Steel PlatesThe high-temperature steel plates are offered by us serves as default material for pressure vessel applications. Boiler quality steel plates are sometimes referred to as boiler grade plates with chemical composition and mechanical properties that make these BQ steel plates. Boilerplates such as steam boilers, boilers made of mild steel
Steel plate production for boilers and pressure vessels . To produce plates from boiler steel, reversing hot-rolling mills are predominantly used (also by cutting hot rolled coil into plates). Concast or rolled slabs from low-alloyed, alloyed and stainless-steel grades are used as semi-products for such rolled products.
