Alloy Steel P91 Pipe

ASTM A335 P91 Pipe Vs ASTM A335 P91 Tube
ASTM A335 P91 pipes and tubes are common piping modules that are used interchangeably as per the requirements in the system. The items can be distinguished from each other based on certain key aspects.

  • A335 P91 pipes are always designed in a circular cross-section. Tubes in this grade can be designed in circular, rectangular, and square cross-sections.
  • P91 tubes are stronger and more robust than P91 pipes.
  • P91 A335 tubes can be hot and cold rolled. A335 P91 pipes are precisely hot rolled in place.
  • Pipes are designed to accommodate larger applications, while tubes are designed to work well with smaller diameter applications.

What Is A335 P91 Material and Sa335 P91 Material
A335/Sa335 P91 material is part of a ferritic alloy steel grade. These items within this range possess high strength that don’t deteriorate with time. The chrome moly grade possesses superior corrosion resistance properties allowing the material within this grade to have excellent performance in stress-induced environments. The chemical content also allows these modules to showcase enhanced resistance to oxidation at elevated temperatures. The versatile grade also exhibits good creep strength and inhibits pitting in marine environments. 

How Do You Weld a P91 Chrome Pipe?
P91 grade is a high-cost grade material that presents some challenges in the welding process. The P91 chrome pipe is produced by preheating the joint at temperatures between 400 to 500 degrees F. This eliminates any moisture and reduces hydrogen content to eliminate embrittlement caused after finishing the weld. To weld, the metal low-hydrogen filler material is utilized, and the module is welded in place by maintaining the correct temperatures. The material can be controlled cooled and stress relieved to restore the ductility of the grade.
