A335 P9 Alloy Steel Pipe that covers “chrome-moly” seamless pipes with remarkable resistance to

corrosion and good tensile strength at high-temperature service. Generally, ASTM A335 P11, P22,

and P91 pipes are used in power generation and in downstream oil and gas, P5 and P9 grades are

for refinery applications.

How to define alloy pipes?

Alloy pipes are tubular with higher percentages, than standard carbon steel pipes, of alloying elements

as Molybdenum (Mo), Chromium (Cr), Nickel, etc. Actually, the ASTM A335 covers “low-alloy” steel pipes,

i.e. pipes that have a total amount of alloying elements below 5%. The addition of higher percentages of

alloying elements (example Nickel and Chromium) transforms the steel into higher alloys, like stainless steel,

duplex, up to super-alloyed materials like Inconel, Hastelloy, Monel, etc.

Alloy pipe is a kind of seamless steel pipe. Alloy tubes are divided into structural seamless tubes and high-pressure heat-resistant alloy tubes. It is mainly different from the production standards and industries of alloy pipes. Annealing and tempering of the alloy tube changes its mechanical properties. meet the required processing conditions. Its performance is higher than that of ordinary seamless steel pipes, and its utilization value is higher. The chemical composition of alloy pipes contains more Cr, which has high temperature resistance, low temperature resistance, corrosion resistance and other properties. Ordinary carbon seamless pipes do not contain or have very few alloy components. Alloy tubes are widely used in petroleum, aerospace, chemical, electric power, boiler and other industries due to their changing mechanical properties and easy adjustment.
Alloy seamless steel pipe is a kind of seamless steel pipe, and its performance is much higher than that of general seamless steel pipe. Because this steel pipe contains more chromium, its high temperature, low temperature and corrosion resistance are unmatched by other steel pipes. Alloy tubes are widely used in petroleum, chemical, electric power, boiler and other industries.
Alloy seamless steel pipe contains elements such as silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron, rare earth and so on.
Alloy Seamless Steel Tube has a hollow section with no joints around the strip. Steel pipes have hollow sections and are widely used as pipelines for transporting fluids such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, alloy seamless steel pipe is lighter in weight with the same bending and torsional strength. It is an economical type of steel that is widely used in the manufacture of structural and mechanical parts, such as oil transport, stair handrails, bicycle frames and steel scaffolding for construction. Using alloy seamless steel pipe to make rings can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, jack sleeves, etc. Steel pipes have been widely used in manufacturing. Alloy seamless steel pipes or indispensable materials for various conventional weapons, gun barrels, gun barrels, etc. must be made of steel pipes. In addition, when the ring section is subjected to internal or external radial pressure, the force is relatively uniform, so the alloy seamless steel pipe is mostly a round pipe
