Alloy Steel A335 P1 Pipes

ASTM A335 Grade P1 (ASME SA333 GR. P1) specification pipe is generally a ferritic alloy steel pipe for high temperature service and this specification falls under the category of low alloy steel pipe. These pipes are manufactured through a seamless production process.

These pipes have a minimum tensile strength of 415 MPa, a minimum yield strength of 205 MPa and an elongation of at least 30%/20%. The tubes are either cold drawn or hot finished, and heat treated from finishing to isothermal annealed or normalized and tempered.

These pipes are ideal for flanging, bending, etc. at high temperatures. These pipes are used in industries such as oil and gas, boilers, chemical and petrochemical as well as high temperature pipes and various engineering applications. These pipes are available in a variety of thicknesses and sizes, depending on the project's specifications. Pipes are manufactured to NPS / NB dimensions and dimensional standards are in accordance with ASME/ANSI B36.10. The ends of these pipes can be provided with threaded, beveled or flat ends.

These P1 pipes are alloyed with different elements to improve their basic physical properties and create new special properties such as heat and corrosion resistance. ASTM A335 P1 pipe combines carbon steel with materials such as aluminum, copper or nickel depending on project requirements. Carbon is the most important element in the mixture. It increases strength, hardness and wear resistance. The downside, however, is that it reduces ductility, toughness, and machinability. To address this, adding molybdenum to the chemical composition of the pipe increases ductility, enhancing its elastic limit and impact quality.
