Type of Sub-products

  • Rtj Weld Neck Flange
    Rtj Weld Neck Flange

    Rtj Weld Neck Flange

    Features a long tapered hub that transfers stress to the pipe, reducing turbulence at the joint. The weld neck connection makes it ideal for high pressure, high temperature pipelines where fatigue resistance is essential.

  • Rtj Slip On Flange
    Rtj Slip On Flange

    Rtj Slip On Flange

    Slides over the pipe and is welded from both sides, offering easier alignment than weld neck flanges. Common in medium to high pressure systems where frequent assembly and disassembly are required.

  • Rtj Blind Flange
    Rtj Blind Flange

    Rtj Blind Flange

    A solid flange with an RTJ groove, used to seal the end of a pipeline, valve, or pressure vessel. Perfect for pressure testing, maintenance, or future expansion in critical service.
