    I've been involved in the welding of P91 with FCAW process.I think your P92 is what we (in the UK) call 'modified' 9% Chrome, which I also have worked on! (at home and don't have access to chemical details). Metrode and Esab both make 'wires' for the FCAW of both types of steel.

  4. Why new U.S. supercritical units should consider T/P92 piping

    T/P92 is being heralded as a superior and lower-cost alternative to T/P91 for new power plants with pressures above 3,600 psi and temperatures above 1,100Fsuch as the supercritical and ultra-supercritical units proposed to be built in the U.S. over the next few years. The switch from T/P91 to T/P92 would represent the next step in an evolution.

    VALIOR P91 and P92 pipe. At high temperatures and pressures, VALIOR P91 and P92 pipes with inside surface protection prevent premature oxidation and thus particle exfoliation and turbine damage. Power plants can be operated at higher temperatures. This leads to reductions in specific fuel consumption and thus CO2 emissions.

    High wall thickness 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. ASTM A335 pipes are often designated as Chrome Moly due to the significant presence of Molybdenum (Mo) and Chromium (Cr) in their alloys.

  8. P91-Special Alloy Steel for High Temperature Application ...

    Welding P91. Welding is one process that is widely used during the construction. This affects the microstructure. Preheating, maintaining inter-pass temperatures, and post-weld heat treatment procedures are very critical for P91 grade. Failure to follow the procedures will result in catastrophic failures.

  9. Welding consumables

    Typically, the best low-alloy flux-cored wire for welding P91 and P92 chrome-moly is an AWS E91T1-B9. This type of wire offers a fast-freezing slag for out-of-position welding, along with low diffusible hydrogen levels to control cracking. It also has a very high tensile strength: approximately 126,000 PSI.

  10. A335 P91 | P91 Material | SA335 P91 | ASTM A335 P91

    Welding P91 generally requires preheating the joint, maintaining interpass temperatures, hydrogen bakes, and postweld heat treatment (PWHT). Preheating, typically to 400 to 500 degrees F, drives off moisture and thereby reduces hydrogen. Hydrogen embrittlement can lead to cold cracking of the finished weld.
