ASME SA335 This specification covers nominal wall and minimum wall seamless ferritic alloy-steel pipe intended for high-temperature service. Pipe ordered to this specification shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding. Selection will depend upon design, service conditions, mechanical properties, and high-temperature characteristics.
P5 alloy steel pipe is a pipe material commonly used in high temperature and high pressure environments, mainly made of alloy steel, with good mechanical properties and corrosion resistance. P5 alloy steel pipes are commonly used in the oil, gas and chemical industries, especially in applications that require high temperatures and pressures.
The chemical composition of P5 alloy steel usually includes chromium (Cr) and molybdenum (Mo), which makes it have excellent strength and toughness at high temperatures.
Advantages
High temperature strength
P5 alloy steel pipe can still maintain good strength under high temperature conditions, suitable for boilers and pressure vessels.
Corrosion resistance
The addition of alloying elements improves its corrosion resistance and prolongs its service life.
Weldability
P5 alloy steel pipes usually have good weldability and are easy to install and maintain on site.
Applications
High Temperature Service
Power Plants
Petrochemical Industry
Refineries
Boilers and Superheaters
