Ring Type Joint (RTJ) Gaskets SEO Page

Ring Type Joint (RTJ) gaskets — also known as RTJ ring gaskets — are precision-machined metallic rings engineered for high-pressure, high-integrity sealing applications. These gaskets fit into grooves in mating flanges and create a metal-to-metal seal under compression. They are widely used in petrochemical, oil & gas, power generation, and heavy process industries where conventional soft gaskets may fail under extreme pressure or temperature.

Why Choose Ring Type Joint (RTJ) Gaskets SEO Page?

• Exceptional sealing under high pressure & temperature
• Metallic construction provides durability and resistance to extrusion
• Zero leakage design when groove and ring match precisely
• Repeats integrity in demanding service
• Compatible with API 6A, ASME B16.20 flange standards
• Wide array of materials & alloy options to match process media and flange metallurgy

Applications

– Oil & gas pipelines, wellheads & subsea systems
– Chemical & petrochemical process plants
– High-pressure steam, power generation & pressure vessels
– Refining, gas processing & hydrocarbon service
– Critical sealing joints in pressure equipment and valves

FAQ – Ring Type Joint (RTJ) Gaskets

Q1: What is an RTJ gasket?
A metallic ring gasket that seals by compression within a machined groove, creating a metal-to-metal seal.

Q2: Are RTJ gaskets reusable?
No — RTJ rings are typically single-use. Removing them permanently deforms the sealing surfaces.

Q3: What flange standards do RTJs match?
Primarily API 6A, ASME B16.20, and in some cases B16.5 / B16.47 depending on groove type.

Q4: Can you supply PTFE-insert RTJ gaskets?
Yes — we can manufacture RX style gaskets with PTFE inserts for corrosion protection or reduced flow turbulence.

Q5: What materials are standard for RTJs?
Soft iron, low carbon steel, stainless steels, duplex alloys, nickel alloys, etc.

Q6: Do RTJ gaskets require special flange finishing?
Yes — groove and flange sealing surfaces must be machined to tight tolerances and smooth finishes for proper sealing.

Q7: Are there different cross-sections of RTJ gaskets?
Yes — oval, octagonal, RX, BX, and hybrid types each suit different flange groove shapes.

Q8: Can RTJs be made blind (solid centre)?
Yes — blind RTJ rings are made for blanking off flanges.
