BX Ring Gaskets are designed for pressures up to 20,000 psi, suitable only for use with API type BX flanges and grooves. The gasket has a square cross section with beveled corners. All BX sizes have a pressure passage hole to equalize pressure across sealing surface.
We Manufacture and supply high quality Ring joint Gaskets for high pressure and temperature service conditions. These gaskets are widely used in Refineries, Petrochemical Industries, Oil drilling well head equipments, Pressure Vessels, valves, Christmas Tree valves and Pipe lines. Ring joints Gasket are strictly manufactured as per API-6A and ASME B16.20 specification.
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.
