Material & Manufacturing Process

P91 / P11 / P22 / P5 / P92 / P9 Alloy Steel Pipe Fittings for High-Temperature Power & Energy Applications.GX Fitting specializes in manufacturing alloy steel pipe fittings for high-temperature, high-pressure and critical service applications. Our experience covers chrome-moly alloy materials including P11, P22, P5, P9, P91 and P92, which are widely used in power generation, refinery and energy industries. These materials require strict control of chemical composition, forming process and heat treatment to achieve stable mechanical properties. GX Fitting applies controlled hot forming, heat treatment, machining and inspection procedures to ensure product reliability. Raw materials are verified through spectrometer analysis and traceability management, while mechanical testing, hardness testing and NDT inspections can be performed according to project requirements. With more than 30 years of manufacturing experience since 1993, GX Fitting provides dependable alloy steel fitting solutions for demanding industrial applications.
