A335 P9 Seamless High Pressure Pipe

gnee manufactures and supplies A335 P9 mild steel pipe, you can search for any size and grade of steel seamless pipe to compare prices.

A335 P9 steel pipe is made from ferritic alloy steel and is suitable for high temperature applications. The main components of A335 P9 alloy steel pipe are 8.00-10.00% chromium, 0.90-1.10% molybdenum, 0.30-0.60% manganese, 0.10-0.50% silicon, and contain a small amount of carbon, sulfur, and phosphorus. The yield strength of A335 P9 seamless pipe is 205Mpa, the tensile strength is 415Mpa, and the elongation of the pipe is about 30%.
The chromium content in A335 p9 high-temperature pipe makes it highly corrosion-resistant. In addition to chromium, A335 p9 seamless alloy steel pipe coated with black paint or anti-corrosion oil on the outside has good corrosion resistance. It can also be galvanized to achieve higher corrosion resistance. Resistance to corrosion. A335 P9 molybdenum-chromium alloy steel pipe is used in industries that transport gases and fluids to factories under high pressure and high temperature, such as power plants, nuclear power plants, petrochemical industries and industrial boilers.

A335 P9 pipes other mechanical test

Transverse or Longitudinal Tension Test and Flattening Test, Hardness Test, or Bend Test
For material heat treated in a batch-type furnace, tests shall be made on 5% of the pipe from each treated lot. for small lots, at least one pipe shall be tested.
For material heat treated by the continuous process, tests shall be made on a sufficient number of pipe to constitute 5% of the lot, but in no case less than 2 pipe.
Notes for Hardness Test:	P91 shall not have a hardness not exceeding 250 HB/265 HV [25HRC].
Notes for Bend Test:	For pipe whose diameter exceeds NPS 25 and whose diameter to wall thickness ratio is 7.0 or less shall be subjected to the bend test instead of the flattening test.
	Other pipe whose diameter equals or exceeds NPS 10 may be given the bend test in place of the flattening test subject to the approval of the purchaser.
	The bend test specimens shall be bent at room temperature through 180 without cracking on the outside of the bent portion.
	The inside diameter of the bend shall be 1 inch [25 mm].
Hydrostatic test	Each length of pipe shall be Hydro tested, at option of manufacture, nondestructive electric testing can be used.
