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.


Frequently Asked Questions

What types of gaskets are used with Ring Joint Flanges?

The most common are oval and octagonal metal ring gaskets, typically made from soft iron, stainless steel, or exotic alloys. Selection depends on pressure rating, flange design, and media compatibility. The metal to metal seal achieved ensures long term reliability, even when thermal cycling or vibration occurs.

Which international standards govern Ring Joint Flanges?

RTJ flanges are produced in strict accordance with ASME B16.5, ASME B16.47 Series A & B, API 6A, MSS SP 44, and ISO/DIN standards. These codes cover dimensions, tolerances, pressure temperature ratings, bolt patterns, and materials, ensuring global compatibility. Compliance also provides traceability, making RTJ flanges acceptable for regulated industries like petrochemicals and offshore oil production.

Where are Ring Joint Flanges commonly applied?

These flanges are used in high pressure, high temperature applications across industries like oil & gas exploration, subsea pipelines, refinery units, chemical processing, and power generation. Their robust sealing makes them ideal for systems carrying hydrocarbons, corrosive fluids, or superheated steam, especially where failure is not an option. RTJ flanges are standard in API and ASME rated equipment for upstream and downstream operations.
