Product Description
BX Ring Type Joint Gasket - Style RTJ 303
The BX ring type joint gasket is actually rectangular in cross section and tapers in each corner in addition to it has a strain balance hole to make certain equalization of pressure which might be trapped in the grooves. BX ring Gaskets have been suitable for higher pressure ratings starting at 5,000 lbs, and ending with 20,000 lbs. They can just be used in API 6BX flanges. Common sizes are supplied in low carbon steel, soft iron, SS 304 and SS 316.The Development of Ring Type Joint gasket
The Ring Type Joint (RTJ) gasket is a forged stainless steel ring that fits to the machined groove of the ring type joint flange. The ring type joint gaskets are generally octagonal or oval in cross-section. RTJ gaskets are likely to be utilized for high-pressure and high heat range applications. It really is commonly used in refinery, petrochemical and oil field drilling industries. The Ring type joint gasket is made as per ASME B16.20. They are compatible with use with flanges created as per standards ASME B 16.5, ASME B16.47, and API 6A.The actual first time to work with ring type joint gasket is from 1920 year, while oval ring type joint gasket began to be used in the United States around the 1920s. They were firstly used in the field of boilers and lately used for manhole covers and other windows in autoclaves. They have gained particular attention in the petroleum production and refining industries. And then by the developing of this gasket, the gasket divided into 3 main types. R, BX, RX type ring type joint gasket.
Style RTJ R
Available in oval and octagonal cross sections. Oval ring type joint gasket and octagonal ring type joint gasket are actually interchangeable on modern flat bottom grooved flanges Regular measurements of Style R gaskets are actually manufactured in accordance with ASME B16.20 and API 6A specifications
Style RTJ RX
RX
ring type joint gasket includes a special self-sealing activity. The
outside bevels of the ring have the original contact giving a seal
resistant to the groove's outer areas. When the inner force raises, the
gasket loads stress and anxiety against the groove to increase the
gasket's sealing features. Style features of the Style RX gasket make it
more resistant to shock load, test pressure shock and drilling
vibration. Style RX ring type joint gasket is perfectly interchangeable
with standard Style R groove designs. Care and attention should really
be applied when interchanging these varieties as RX ring type joint
gasket is higher and will add more length to the accomplished
construction.
Style RTJ BX
Style
BX ring type joint gasket possesses a pitch diameter slightly bigger
than the groove pitch diameter. This enables for initial contact being
made on the outside of the ring, pre-loading the gasket which results in
a tension energized seal. BX gaskets incorporate a tension passing that
allows caught tension to balance itself in the joint. Style BX ring
joint gaskets can only be used with API 6BX flanges and are not
interchangeable with Style RX.
And other style types also include SRX, SBX, IX ring type joint gasket.
BX Ring Type Joint Gasket Materials
The materials of BX Ring Type Joint Gasket shall match the flanges material but must have a lower hardness around 15 to 20 HB, this to ensure that the gasket get plastically deformed within the groove of the flanges as the two connecting ring type joint flanges are bolted together. Or if a harder material used for the ring type joint flange, the groove of the RTJ flange would be damaged as the flanges are tightened.The materials can be: Soft iron, SS 304, SS 316, F5, SS 321, SS 347, SS410, Monel 400, Inconel 600, inconel 625, Inconel 625, Inconel 718, Hastelloy C276 and other metals.
