Why is the ASTM A335 P11 pipe the most popular grade among high temp applications such as boilers and refineries?

High-temperature applications such as boilers and refineries widely employ the ASTM A335 Gr P11 due to many convincing benefits. SA335 P11 pipe is designed to withstand elevated temperatures and high-pressure environments commonly found in boilers and refineries. A335 P11 has good resistance to creep deformation, which is essential for maintaining the structural integrity and safety of high-temperature equipment.

Boilers and refineries often encounter corrosive environments because of the presence of various chemicals, high temperatures, and pressure. P11 seamless pipe has excellent corrosion resistance, particularly in environments where sulfur and hydrogen are present.

P11 Material Welding

P11 Material Welding

A335 P11 pipes welding process is generally done via an electrode, gas, and tungsten arc welding process. The SA335 Gr P11 grade can be welded based on mechanical properties, chemical composition, and welding conditions. The SA 335 P11 has poor weldability and is susceptible to cold cracking. Several measures have to be taken during the welding process.

The electrodes of the SA 335 Gr P11 grade must be preheated and thermal shock and quenching should be avoided. The natural condition of the welding should be controlled. After the post weld heat treatment, the hardness should not be greater than 225 HB.

What is the best method for P11 chrome pipe welding and fabrication?

Also known as stick welding, SMAW is the best method for A335 Gr P11 welding. SMAW is relatively easy, cost-effective, and suitable for both field and shop welding as compared to the other welding methods.

Apart from SMAW, GTAW, commonly known as TIG welding, is another precise and high-quality welding method for a P11 pipe. GTAW provides excellent control over the welding process and is suitable for thinner wall thicknesses or critical joints.

The fabrication process for SA 335 P11 typically involves several steps to ensure proper handling, cutting, shaping, and joining of the pipe. Pipe cutting, bending, welding, and post-fabrication treatments are the steps found in the A335 P11 pipe fabrication.

P11 seamless pipe vs P12

This seamless pipe generally has higher mechanical properties compared to P11. The minimum tensile strength of P12 is usually 415 MPa and the minimum yield strength is 220 MPa. On the other hand, the A335 P11 material displays a minimum tensile strength of 415 MPa, and the minimum yield strength is 205 MPa.

SA 335 Gr P11 is widely used in high-temperature applications and sectors such as boilers, power plants, and refineries. SA335 P11 material pipe can adequately handle moderate to high temperatures typically up to 550°C or 1022°F.

P12 seamless pipe is also utilized in high-temperature applications, especially in power plants and refineries. A P12 pipe can handle slightly higher temperatures compared to P11 typically up to 600°C (1112°F).

What are the temperature limit, density, and equivalent of ASTM A335 P11?

SA335 Gr P11 can operate sturdily in high-temperatures and is typically suitable for operating temperatures up to 550°C (1022°F). This temperature limit is based on its mechanical properties and resistance to creep deformation at elevated temperatures.

The density value of P11 materials and products is typically around 7.85 g/cm³ 0.28 or 36 lb/in³. This density value may differ at times based on the composition and the process followed by the P11 pipe manufacturer.

1.7335 pipes have several equivalent materials in different international standards such as EN/DIN 13CrMo4-5 (1.7335), BS 3604 620-440, and JIS STBA23. While these pipe materials are considered equivalents, there may be slight differences in their exact chemical compositions and mechanical properties.

Post Weld Heat Treatment (PWHT) Requirements

PWHT is not mandatory for the UNS K11597 pipe, but it may be required under certain circumstances. PWHT is typically employed to relieve residual stresses and improve the mechanical properties of welded joints.

To determine the specific hardness values after PWHT of ASTM A335 P11 alloy steel pipe, refer to the specific PWHT procedure. You also need to follow the guidelines provided by the applicable codes and standards such as ASME Boiler and Pressure Vessel Code Section VIII, Division 1.
