Metallic Gaskets - Tyco Products

Metallic Gaskets

Metallic Ring type Joint gaskets are used in high pressure applications for exploration and production in Oil and Gas Industry.

A gasket is used to create and retain a static seal between two flanges which connect a series of mechanical components while containing a wide variety of fluids (liquids and/or gases). These static seals aim to provide a complete physical barrier against the fluid contained within and block any potential leak paths through gasket material or between surfaces of flange and gasket, while still being capable of being disassembled and reassembled.

Ring Type Joint Gaskets (RTJ Gaskets) Ring Type Joint (RTJ) gaskets are vital components in ensuring secure, leak-free connections in high-pressure and high-temperature environments, common in industries like oil and gas, petrochemical, chemical processing, and power generation. These precision-machined metallic gaskets meet industry standards API 6A, API 17D, and ASME B16.20 and feature a distinctive oval or octagonal design, fitting precisely into grooved flange chambers, creating a reliable metal-to-metal seal when flanges are tightened. RTJ gaskets are available in various materials, including carbon steel, stainless steel, and specialized alloys such as Monel and Inconel, ensuring adaptability to diverse industrial needs

A standout feature of RTJ gaskets is their unique ability to deform under compression, allowing them to tightly conform to flange face irregularities, resulting in dependable and leak-free seals, even in the harshest operating conditions. Their excellence in extreme pressure and temperature environments makes them highly valued. Their adaptability in terms of size and material options further adds to their versatility and widespread use in critical applications, especially in industries where maintaining dependable seals between flange connections is of utmost importance, ensuring safety and reliability. RTJ gaskets are a trusted choice for professionals working in demanding and high-stakes environments.

Selecting the right material for Ring Type Joint (RTJ) gaskets is crucial for effective sealing in various applications.

Gasket material selection hinges on two key factors: compatibility with the fluid being sealed and the flange's hardness. Ideally, the gasket material should be softer than the flange material to allow for proper gasket deformation without harming the flange surface.

Soft Iron: Ideal for low-pressure applications with non-corrosive or non-abrasive fluids.
Low Carbon Steel: Suitable for general-purpose use with low to moderate pressure and temperature conditions.
Inconel: Offers excellent resistance to high temperatures and aggressive chemical environments, making it suitable for extreme conditions.
Monel: Resistant to corrosive substances, ideal for offshore and marine applications.
Duplex and Super Duplex: Ideal for demanding applications requiring robust strength, outstanding corrosion resistance.
Hastelloy: Designed for use in highly corrosive and high-temperature environments.
f5: provides exceptional chemical resistance, high-temperature performance, mechanical strength, tight sealing, durability, and compatibility with diverse flange materials, making it ideal for demanding industrial uses.

Benefits of Using RTJ Gaskets Ring Type Joint Gaskets offer several advantages over other types of gaskets, making them the preferred choice for high-pressure and high-temperature applications. Some of the key benefits include:

High-Pressure Sealing RTJs are specifically designed to withstand extreme pressures, making them ideal for applications where standard gaskets may fail.
High-Temperature Performance Metallic RTJs can withstand elevated temperatures without losing their sealing properties, ensuring reliable performance in demanding environments.
Excellent Chemical Resistance Ring Type Joint Gaskets are available in a wide range of materials, including specialized alloys, offering excellent resistance to corrosive chemicals and aggressive fluids.
Longevity and Durability RTJs are precision machined from high-quality materials, ensuring durability and extended service life.
Reliable Sealing The design of RTJs, with their grooved chamber and precision machining, ensures a tight and leak-free seal, reducing the risk of process fluid leakage.

R-Oval Gaskets

R-Oval type gaskets, abbreviated as OVL, are designed for sealing flange grooves with a flat bottom v-groove or a bottom radius groove. They offer reliable performance in pressures up to 10,000 PSI, although the octagonal type boasts a higher sealing coefficient and is generally preferred.

R-Octogonal Gaskets

R-Octagonal gaskets are essential for high-pressure applications, with a superior sealing coefficient compared to oval counterparts. Designed to match the flange groove's pitch diameter, they excel in flat-bottom v-grooves and remain the preferred choice for effective sealing at pressures up to 10,000 PSI.

R-Octogonal Gaskets

RX Gaskets

The RX type ring gasket is a high-pressure metallic seal used in industries like oil and gas, petrochemical, and chemical processing, particularly in API 6A flanges for challenging & extreme outrageous conditions. We offer wide range of Type Rx Gaskets ranging from RX20 to RX215.

BX Gaskets

BX gaskets, compatible with R Type Oval and Octagonal rings for API 6BX flanges, withstand pressures up to 20,000 PSI. A pressure balance hole is incorporated in BX gaskets which ensures the pressure equalisation. Our range includes BX150 to BX303 gaskets for various applications.
