ASTM A335 P5 P9 P11 P22 P91 ASTM A213 T2 T5 T9 T11 T12 T22 T91 High Pressure Alloy Boiler Tube Heat Exchanger Tube
ASTM A335 Pipe (ASME S/A335, Chorme-Moly) is a seamless ferritic Alloy-Steel Pipe for high temperature service. Pipe ordered to this specification shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding. Sometimes referred to as "P Grade", Chrome Moly Pipe is popular in P-Grades P5, P9, P11, P22, and P91. The most common use of grades P11, P22, and P91 is in the power industry and petro-chemical plants, Grades P5 and P9 are commonly used in refineries.
A335 is often called chrome moly pipe because of the chemical
makeup of Molybdenum (Mo) and Chromium (Cr). Molybdenum increases
the strength of steel as well as the elastic limit, resistance to
wear, impact qualities, and hardenability. Moly increases the
resistance to softening, restrains grain growth and makes chromium
steel less susceptible to embrittlement. Moly is the most effective
single additive that increases high temperature creep strength. It
also enhances the corrosion resistance of steel, and inhibits
pitting. Chromium (or chrome) is the essential constituent of
stainless steel. Any steel with 12% or more Chrome is considered
stainless. Chrome is virtually irreplaceable in resisting oxidation
at elevated temperatures. Chrome raises the tensile, yield, and
hardness at room temperatures. The composition chrome moly alloy
steel pipe make it ideal for use in power plants, refineries, petro
chemical plants, and oil field services where fluids and gases are
transported at extremely high temperatures and pressures.
ASTM A213 seamless pipes tubes Standard Specification for Seamless
Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and
Heat-Exchanger Tubes This specification covers seamless ferritic
and austenitic steel boiler, superheater, and heat-exchanger tubes.
Grades containing the letter H in their designation have requirements different from those of similar grades not containing the letter H.
These different requirements provide higher creep-rupture strength
than normally achievable in similar grades without these different
requirements. The tubes shall be made by the seamless process and
shall be either hot finished or cold finished, as specified. Grade
TP347HFG shall be cold finished. Heat treatment shall be done
separately and in addition to heating for hot forming. The ferritic
alloy and ferritic stainless steels shall be reheated. On the other
hand, austenitic stainless steel tubes shall be furnished in the
heat-treated condition. Alternatively, immediately after hot
forming, while the temperature of the tubes is not less than the
minimum solution temperature, tubes may be individually quenched in
water or rapidly cooled by other means. Tension test, hardness
test, flattening test, and flaring test shall be done to each tube.
Also, each tube shall be subjected to the nondestructive electric
test or hydrostatic test.
