ASTM A335 P11 Pipe (ASME SA335 P11) is Chrome Moly Alloy Seamless
Pipe that used for high-temperature services, P11 Grade Pipe Chrome
content at 1.00% to 1.50%, Moly content 0.44% to 0.65%, Minimum
tensile strength 415MPa, minimum yield strength 205Mpa.
P11 pipe material has high toughness and high wear and tear
resistance, it could be used to manufacture pipe fittings like
elbow, tee, reducers, and flanges as following standard:
Pipe fittings standard: ASTM A234 WP11
Flange Standard: ASTM A182 F11
Equivalent Steel Plate Standard: ASTM A387 Grade 11/ ASME SA387
Grade 11
Welded pipe standard: ASTM A691 1-1/4 CR
ASTM A335 specificaton covers nominal wall and minimum wall
thickness pipe that with alloy material and manufactured in
seamless type. The pipe under this specification shall be suitable
for bending, flanging, and all the other similar processing and
formations. Although it shall be good for fusion welding.
ASTM A335 P11, P22 – Common Use Grade
ASTM A335 P11 and P22 are most common use in Chrome Moly Alloy
Pipes for high temperature environment, for power industry and
petro-chemical plants.
Chrome Moly Alloy ASTM A335 pipe
ASTM A335 pipe called chrome moly pipe as they have a high level of
Chromium and Molybdenum presence in it. While Molybdenum increases
the overall strength, resistance, elasticity, hardenability and
overall quality, moly ensures that the material is more resistant
to softening, restrains the growth of grains and lessens the
chances of embrittlement. It is the single additive that is
responsible for the increase in high temperature resistance (to
540-750°C) and it also improves the corrosion resistance to steel.
Key Elements – Chromium
Chromium is a key component that is used in the manufacture of
stainless steel. If the chromium levels are above 12%, it can be
classified as stainless steel. The oxidation resistance potential
of chrome is irreplaceable even in elevated temperatures. The
hardness, tensile and yield strength is better at standard
temperatures. Due to the composition of the material, it is ideal
to be used in power plants, refineries, petro-chemical plants and
other oil field services when there is transportation under high
temperatures and pressures involved.
