X52 Carbon Steel Welded Pipe ASTM A209m-03 Boilers

X52 Steel Chemical Pipeline

Fluid pipe is a kind of pipe with a hollow section with a hollow section, a large number of pipe used for the transportation of fluid transportation of oil, natural gas, gas, water and some solid materials pipelines.Compared with solid steel such as round steel, steel pipe has the same bending and torsional strength and lighter weight.

ASTM A179-90A (Reapproved 2001) Cold-drawn seamless low carbon steel heat exchangers and condenser tubes, ASTM A192/192M-02 Seamless boiler tubes for high pressure carbon steel,ASTM A209/ A209m-03 seamless carbon molybdenum alloy steel tubes for boilers and superheaters. Normally, they are used for the industries including electricity, Sewage treatment water piping,chemical, petrochemical, boiler, heating, ship-building and the construction industry etc.Pipes are manufactured according to the standard of API, ASTM, ASME, JIS, DIN, BS, EN, UNI, NFA, GB, domestic and international standards.Normally, in china when the pipe outer diameter is within 57mm, we usually use cold drawn pipes, while up to that 57mm, we use hot rolled ones.

Seamless steel tubes are widely used.General purpose seamless steel tubes are rolled from common carbon structural steels, low alloy structural steels or alloy structural steels to achieve the highest yield and are mainly used as conduits or structural parts for fluid delivery.2, according to different uses divided into three types of supply: a, according to the chemical composition and mechanical properties supply;B. Supply according to mechanical properties;C. Supply according to hydraulic test.Steel tubes supplied under Class A and B, if used to withstand liquid pressure, shall also be hydro-tested.3, special purpose seamless pipe with boiler seamless pipe, chemical power, geological seamless steel pipe and petroleum seamless pipe.
