Description

Carbon Steel: Gasket Stainless Steel: Seal
Metal: Seals Ring Soft Iron: Gasket

High Light: API 6A BX 156 ring gasket, heatproof ring type joint gasket, BX 156 ring type joint gasket

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.

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.

Type BX

–NB1 11/16″ to 21 1/4″ Class Rating 5000 to 20000 ASME B16.20

» BX Ring gasket Suitable for use on API 6BX Flanges up to Class 20000
» During installation the ring is compressed inwards to provide
additional sealing stress
» Pressure energised; as the internal pressure increases the
sealing force increases
» Type BX rings are supplied with pressure relief holes to avoid
compressing fluid beneath the gasket
» Can be drilled with additional hole to create a gasket suitable
for subsea installation Type “SBX”

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.

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.

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.
