Oilfield Monel 400 R30 RTJ Ring Gasket

Description

High Light: Monel 400 RTJ ring gasket, R30 RTJ ring gasket, Monel 400 RTJ gasket types

The Ring Type Joint Gasket is initially developed for high pressure/ temperature applications found in the petroleum industry and is primarily used in the oilfield on drilling and completion equipment.
However, today this product range can also be found on valves and pipe work assemblies, along with some high integrity pressure vessel joints.
Style R gaskets are manufactured in accordance with both API 6A and ASME B16.20 to suit API 6B and ASME/ANSI B16.5 flanges. Available in both oval and octagonal configurations, both types are interchangeable on modern octagonal type grooved flanges.
Pressure: 2,000-5,000 PSI

We can offer more than 30 kinds of materials, such as 321SS, 347SS, 316SS, 304SS, Inconel 625, Monel 400, INCOLY 825, Nickel 200, Duplex F44, soft iron, low carbon steel and so on. We have over 10 years experience in export business. Our products are sold to Southeast Asia, Middle East, Europe and America and well appreciated by our clients.

Oval cross-section Industry Ring Joint Gaskets and Octagonal cross section Ring Joint Gaskets are used in pressures up to 10,000 psi

The hardness of the ring gasket should always be 30% lesser than the hardness of the flanges to prevent flange deformation

Dimensions and Tolerances for Ring Joint Gaskets and Grooves are covered in API 6A and ASME B16.20.

We stock a wide range of sizes and materials ready for immediate shipment from Ring Numbers R11 to R105.

Ring type joint gaskets(RTJs) are designed for high pressure applications. They are available in a variety of forms to suit different flange formats . RTJs can be used for very high and/or fluctuating pressures (up to 1500 bar), depending on the profile selected. Material selection determines use for high temperatures (up to i000°C) and in aggressive media. To ensure proper sealing the surfaces of contact between the gaskets and flange have to be carefully processed. The small sealing area and high contact pressure results in excellent sealability.

As a result of metal to metal sealing media they are made to be free of indentations, tool marks etc and have a surface finish of maximum,

· R, RX – 63 microinches Ra (1.6 micrometer Ra).

Thus Gasket supplies ring joint gaskets (RTJ Gasket) with the hardness numbers as follows:

Marking and Identification (standard):

The outer surface of each Ring Type Joint should show the manufacturer’s name or a trademark, the gasket number like R67, RX37 or BX155, gasket’s material in abbreviation(check below our chart), as well as the standards like ASME B16.20, API 6A, API 17D, etc.
