ASTM A335 P9 Welded Pipe

The a335 p9 pipes, made from ferritic Alloy-Steel, are meant for high temperature applications. the sa335 p9 material chemically contains metals like Molybdenum and Chromium added to the alloy. By the addition of metals like Molybdenum and chromium, there is an increase in the tensile strength of the alloy. The yield strength of the a335 p9 welded pipe is 205 Mpa, while its tensile strength is 415 Mpa. The elongation percentage of the pipe is about 30%.

Both these elements are known to improve the pipe’s resistance to wear, its impact qualities, hardenability, as well as its elastic limit. They also cause an increase in its mechanical properties like - the prevention of grain growth, reduced brittleness, the increase the creep strength at high temperatures and has excellent resistance to softening.

The chromium content in the a335 p9 pipe makes it highly resistant to corrosion. Therefore, the a335 p9, has excellent resistance to oxidation at elevated temperature. Besides chromium, astm a335 p9 alloy steel pipes that are externally coated with either Black oil paint or anti-corrosion oil show good resistance to corrosion. It could also be galvanized with zinc. Galvanization with zinc increases its resistance to atmospheric corrosion.

sa335 p9 Pipes may be manufactured by forming them either through hot finishing or cold drawing. After forming, the pipes have to be finished with heat treatment that includes Full or Isothermal Annealing, Normalizing and Tempering. There are four types of sa335 grade p9 pipes that are manufactured - Welded, Fabricated, Seamless and ERW

The pipes are available in threaded ends, plain ends or bevel end. And both the ends of these pipes are protected by plastic caps. The asme sa335 grade p9 pipes and tubes are manufactured in several forms like – rectangle, coiled, round, square, hydraulics, U-shaped and pancake coils.

Application of the a335 grade p9 pipes and tubes include industries that require transportation of gas and fluid at high pressure and temperatures from the off-site or onsite to the plants. E.g. – power plants, nuclear plants, petrochemical industries and industrial boilers need pipes to convey oils, water, steam and gas across from the site to plant
