BX SeriesNPSClass Ratings
BX• Used in special applications involving high pressure from 5000 psi to 20000 psi.
• Provides a pressure energized seal.
• Not recommended for re-use.
• Available in ring no. BX150 to BX172.
1-11/16”-21-1/4”5000-20000 API Flanges

The Style BX ring type joint is manufactured in accordance with API 6A.
All BX ring type joints incorporate a pressure passage hole to allow for pressure equalization each side of the sealing faces. On assembly, metal to metal contact of the flange faces is achieved.
The Style BX is not interchangeable with any other style, and is only suited for API 6BX flanges. Style BX ring type joints are designed to seal pressure up to 20,000 PSI (1,360 bar) in accordance with API 6A pressure ratings.

Designs are also available for Subsea applications.

Styles SRX and SBX are derived from Styles RX and BX, and are produced in line with the API Standard 17 D for use on subsea wellhead and Christmas tree equipment.

SEALS RING GASKET high pressure and high-temperature according to API 6a asme16.20.

We has more than 200,000 standard size ring joint gaskets in stock and available for immediate shipment. These include all popular sizes of “R”, “RX”, and “BX” style gaskets. Dan-Loc Group stocked gaskets include Low Carbon Steel, F5, 304, and 316 materials.

The BX type RTJ gaskets are manufactured in accordance with API 6A and are suitable for use in high pressure API 6BX flanges. The gaskets form a metal to metal seal on assembly and the efficiency improves as internal pressure increases. All BX sizes have a pressure relief hole to equalize pressure across sealing faces.

Type BX

Size Range :Available from Ring No. BX150 to RX 162 to suit the following flange specifications:

The API 6A ring gaskets for 6B flanges would be the R & RX type, and for 6BX flanges, gaskets would be the BX types.

–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”

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,

BX – 32 microinches Ra (0.8 micrometer Ra)

Type BX operates in 20,000 psi with non interchangeability. Type BX has a pressure passage hole for pressure equalization on each sealing face sides.

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.

Additionally: IDT Profile Overview | RJ Series

Because Ring Joint gaskets are used in extreme operating condi-tions, it is of utmost importance to select the most suitable, metallic material. In addition to pressure and temperature, the resistance towards the conveyed media has to be con¬sidered. The hardness of the gaskets should usually be lower than that of the flange material in order to prevent mechani¬cal damage to the flange.
