The company can supply extruded, CR or CD superalloy pipes for use at ambient temperature up to 1300℃. The products are widely used in aviation, aerospace, petrochemical, metallurgy, machinery, energy, power, nuclear industry and building materials. It meets the harsh requirements of high temperature, thermal ablation, wear and various acid, alkali, salt environments.
Production process
Hot process: Extrusion + Perforation (pierced billet)
Cold process: CR + CD + Cold broaching (green pipe)
NDE: Eddy current inspection + UT + Hydraulic pressure inspection (Finished pipe)
