What is the P11 chrome pipe?
The chrome P11 pipe is a strong device that is designed with chromium and molybdenum as its primary constituents. This gives the 1.7335 pipes good corrosion resistance properties in harsh environments. These pipes have good higher temperature strength and hardness at room temperature.
The A335 P11 grade has excellent mechanical strength with an outstanding elastic limit. These devices showcase enhanced resistance to wear and impact in the system. The SA335 P11 material can be shaped in different sizes and resists grain growth, and are less susceptible to embrittlement.

P11 Material Welding

A P11 pipe 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.
