ASTM A335 P5 pipe

What are the 3 manufacturing processes for SA335 Grade P5 seamless pipe?

Since I work with a reputed SA 335 pipe supplier for many years, I can answer this question with authority and experience.

Pipes with high strength are in high demand for transmitting fluids and gases in high-temperature conditions. P5 pipes are made from ferritic alloy steel with molybdenum and chromium. A335 P5 material has high corrosion and heat resistance due to chromium and molybdenum. It is because of its high tensile strength of 415 Mpa minimum and yield stress of 205 Mpa minimum.

There are many manufacturing processes for making SA 335 P5 pipes with high wear and tear resistance. But buyers must also check if these processes follow the ASME, ASTM, And API standards for increasing their strength, hardenability, elastic limit, and impact qualities for many applications.

The three significant manufacturing processes for producing A335 P5 pipes include the following.

• The hot rolled process is one of the manufacturing processes to have rough surfaced high-quality pipes for many high-temperature applications.
• The cold rolling process happens at room temperature running pipes over dies for having excellent surface finish and enhanced tolerance.
• The manufacturing process includes many surface finishes like bare, oiled mill vanish, FBE dual, oiled, 3LPE, coal tar, 3LPP, tape wrap, concrete coating, etc., with end finishes like beveled, square cut, coupled, threaded, and others.

What is the purpose of the annealing and tempering process of the ASTM A335 GR P5 pipe?

A335 gr P5 low carbon chromium-molybdenum steel pipes undergo an annealing and tempering process for the following purposes, among others.

• Tempering increases the wear and tear resistance and high tensile strength of 586 Mpa minimum at room temperature.
• Annealing increases ductility, elasticity, toughness, formability, hardness, and other physical and mechanical properties.
• Tempering and annealing heat treatments make the ASTM A 335 pipes useful in many applications in harsh conditions involving high temperature, pressure, corrosion, etc.

What is the difference between LSAW and HSAW P5 pipes?

The following are a few differences between LSAW and HSAW P5 pipes, among others.

• LSAW or longitudinal submerged arc welded P5 pipes are best for effectively transporting hydrocarbons for long distances.
• HSAW or spiral submerged arc welded pipes made of the helical metal coil are cheaper than metals or alloys and are best for use in many non-critical applications
• LSAW P5 pipes manufactured by bending, cutting, and welding steel plates by the JCOE process are expensive and used in many critical applications, contrary to HSAW pipes

What is the tempering temperature of P5 material?

P5 pipe material makes many pipes like LSAW, HSAW, SSAW, SSAWL, and other pipes useful in several sectors. It is because of its high tempering temperature of 1250 F or 675 C.

P5 pipes have high tensile strength and tempering temperature because of the ASTM A335 P5 chemical composition. It is because of its less carbon content of only 0.15%, 4 to 6% chromium, 0.5% silicon, 0.45 to 0.65% molybdenum, and others.

ASTM A335 P5B erw pipe and SA 335 P5C welded pipes are available in sizes ranging from 1/2” to 36”

What is the size range of the ASTM A335 P5B ERW pipe?

ASTM A 335 P5 B ERW pipes are available in a wide size range for use in several applications in various sectors. The standard sizes range between one eight of an inch to 30 inches.

The peculiar P5 steel alloy composition makes it easy to bend, cut and weld in many sizes and shapes like square, rectangular, hexagonal, round, etc. Since these high-pressure ASTM A335 P5 pipes are useful in various applications, the experienced suppliers offer them in customized sizes to fulfill specific needs.

What is the hardness of the ASTM A335 P5 pipe?

The hardness of the ASTM A 335 P5 pipe depends on many factors. It is because A335 pipes, known as chrome moly pipes made of the chemical makeup of chromium and molybdenum.

A335 P5 pipe shall have a hardness not exceeding 25 HRC or 250 HB, or 265 HV to be useful in specific applications. Buyers should confirm the hardness with many test certificates from reputed suppliers to be useful for particular purposes.
