Order Information From Spiral Wound Gasket Manufacturers

As one of the leading spiral wound gasket manufacturers, we have 5 types of spiral wound metallic gaskets:

 

Spiral Wound Gasket Types

R Type Spiral Wound Gasket(Basic Type)

  • Item no.: JSG – SW10
  • SWG with only filler and winding (sealing element only), suitable for high pressure and temperature applications for TG/male/ female flange.
  • For example: SS304/FG.

Spiral wound gasket type R is the basic style industrial gasket, its inner and outer diameter requires a minimum of three plies and a maximum of five plies of preformed stainless steel strip without filler, which provides greater stability and better compression characteristics. The outer windings shall be spot welded circumferentially with a minimum of three welds or a maximum space between spot welds of 76mm when the gasket’s dimension increases.

CGI Type Spiral Wound Gasket(CGI Gasket)
  • Item no.: JSG – SW20,
  • CGI spiral wound gasket with inner ring and outer ring, for raised & flat face flange.

For example: SS304/SS304+FG/CS spiral wound gaskets CGI are supplied with an external and an internal ring that is suitable for use on flat face and raised face flanges and can be especially for high pressure or temperature environments or where corrosive or toxic media exists. The inner ring gives the gasket a greater resistance to thermal shock and prevents the filler material from being sucked in when in the case of vacuum services as well as gives an additional compression limiting stop and prevents inward buckling ring. Always the inner ring’s material is typically the same as the winding material but can be provided in other materials depending on the services.

CG Type Spiral Wound Gasket(CG Gasket)
  • Item no.: JSG – SW30
  • SWG with only outer ring, for raised / flat face flange
  • For example: SS304/FG CS Gasket

Ginseal provides CG type spirotallic gasket (with only outer ring). These spiral wound flange gaskets are proved to be suitable in most applications, and allow lower clamping forces than solid gaskets, albeit with a higher cost.

The spiral wound gasket copes with an outer ring made from stainless steel, carbon steel or other material like Duplex, Monel or Nickel are always for applications of raised face flanges. The outer ring works as a center ring that fix the gasket on the flange faces by providing the blow-out resistance of the windings as well as works as a compression stop. The CG spiral wound is a good general-purpose gasket and suitable for use with a flat face and raised face flanges.

RIR Type Spiral Wound Gasket
  • Item no.: JSG – SW40
  • SWG with only inner ring &. without the outer ring, it’s suitable for the male and female flange.

RIR type spiral wound gasket with inner ring and without outer ring is mainly used in the male and female flange. The solid inner ring acts as a compression stop and fills the annular space between the flange bore and the inside diameter. It’s designed for use on a heat exchanger where the sealing area is limited. The inner ring’s use can prevent accumulations of solids as well as reduce the turbulent flow of process fluids and minimize erosion of flange faces.

H Type Spiral Wound Gasket
  • Item no.: JSG – SWH
  • Spiral Wound Gasket for heat exchanger.

For Example SS304/FG with 1 bar of Double Jacketed. Ginseal H type spiral wound gasket is a kind of heat exchanger spiral wound gasket which is created for heat exchangers, It’s same with common spiral wound gaskets in structural type except that barrettes(bar) are required and the bars/ribs are securely fastened to the ID of the gasket. Always the barrettes are always double jacketed type or kammprofile type in the same material of windings and fillers.
H type spiral wounds can also be equipped with an external ring and an internal ring to provide better stability but kindly refer to Ginseal technical team for the use of applications.

How To Choose Filler

The important part is the sealing element (also called spiral wound gasket filler) made up of V-formed SS strip and non- metallic filling tape, the material can be changed according to different chemical compatibility requirements.

  • Spiral wound gasket graphite filler strip is good to be used in a high-temperature environment,
  • PTFE Spiral wound gasket filling strip is for acids and another corrosive medium.
  • Spiral wound gasket non-asbestos’ use is increased when the health problems with asbestos became known. But it’s only recommended for low temperature less severe applications due to the rubber content.
  • Ceramic is for extremely high-temperature applications. The filler is not so common as it cannot achieve the same leak tightness as graphite

Ring Joint Gasket https://www.ginseal.com/ring-joint-gaskets/ https://www.ginseal.com/ring-joint-gaskets/#respond Sat, 18 Apr 2020 04:09:38 +0000 http://ginseal.seowaimao.com/?post_type=product&p=1113 Factory outlet gasket from China Ring Joint Gasket Manufacturer with high performance and affordable price. Ginseal Ring Type Joints are a kind of forged ring which will be installed into the machined groove of an RTJ flange. After tightening the bolts, the ring joints will be compressed between the flanges into the grooves, and the rings will give an efficient sealing function after deforming. In this way, the metals material for the API ring gaskets is typically chosen to be softer than the flange material in order to prevent any damages to the flanges.

Ring joint gaskets are widely used in refinery, petrochemical and oil field drilling industries. and the rings are generally used for high pressure and high-temperature applications.
Ginseal RTJ flange gasket is manufactured in accordance with API - 6A, API 17D, and ASME B16.20 specifications and comes in six basic profiles: R oval, R octagonal, RX, and BX, SRX, SBX.

There are 4 types of ring type joint gasket:

ring joints

RTJ Gasket Size Chart

Type R ( oval/ octagonal ) Ring Type Gasket

  • Item No.: JSG – RJR1 / JSG- RJR2

R Style seal ring gasket or named oval gasket as the basic type of RTJ gasket is available in both oval and octagonal configurations, the octagonal ring joint gasket is recommended in higher sealing efficiency, both types are interchangeable on modern octagonal type grooved flanges. However, only the oval cross-section can be used in the old type round bottom groove as the oval ring gasket are the original type of RTJs.

R type ring gaskets are manufactured in accordance with ASME B16.20 followed with ASME B16.5 flanges, class 150 to 2500. They are designed for sealing pressure up to 6,250 psi according to ASME B16.5 pressure ratings.

R series flange ring gasket is available in ring numbers R11 up to R105, Ginseal also can provide customized R type RTJs with drawings.

Type RX RTJ Ring Gasket

  • Item No.: JSG – RJRX

Ginseal RX ring type joints are similar in the shape of the octagonal ring gasket, while the RX type rings’ cross-section is designed to take advantage of the contained fluid pressure in effecting a seal. RX ring joint gaskets are also manufactured according to API 6A, ASME B16.20. The ring-type joints are used at pressures up to 15000 psi, and the RX type is wider than R type joints in this way the flange face to face separation will be higher compared with the R type gaskets.

RX ring joint flange gasket is a pressure- energized adaptation of the standard Style R gasket. The modified design uses a pressure – energized effect that improves the efficiency of the seal as the internal pressure of the system increases.

Type BX RTJ Joint Gasket

  • Item No.: JSG – RJ BX

BX pressure energized gaskets are manufactured in accordance with API 6A and are designed for use on pressurized systems up to 20, 000 PSI. On both the inner and outer diameters, all BX RJ gaskets incorporate a pressure balance hole to ensure equalization of pressure that may be trapped in the grooves.

BX type ring joint flange gaskets are engineered for the highest pressure ratings up to 20,000 psi compared with R type & RX type ring joints. They cannot be interchangeable with any other types like R type or RX type. It is a typical solution required by a special arrangement.

Blowout resistance, opening in the axial direction gives the BX type ring type joint gaskets the function of balancing the pressure loads in the situation when the inner sealing barrier is not tight.

BX ring gaskets are manufactured only in the dimension standards to NPS 30.

Type SBX / SRX

  • Item No.: JSG – RJ SBX/ RT SRX

Type SRX and SBX metal ring joint gaskets are manufactured as per API 17D for Subsea environment and Tree Equipment are vented to prevent pressure lock when connections are made up underwater. They have the same dimensions as Type RX & BX RTJ ring joint gasket with the same number designation, and also they are suitable for the same corresponding connectors. The “S” prefix shows these gaskets have vent holes, allowing a pressure less when underwater. With the vent holes, any water trapped between a ring groove bottom and the sealing area of the gasket can escape to the equipment I.D. bore.

SBX ring joints

Ginseal RTJ gaskets are designed to seal by “initial line contact” or wedging action between the mating flange and the gasket. It is essential to choose a softer metal of the gaskets while the flange’s material should be harder to make sure the ring type joints can give a very tight and efficient seal after applying pressure on the sealing interface through bolt force. Usually, the ring gaskets are used in oil, petroleum and chemical process fields. As precision machined, metallic sealing rings, ring joints are suitable for high pressure and high-temperature applications.

Ring Joint Gasket Material

There’s a variety of material can be selected for the RTJ gasket material according to a different application.
Check as below:
Soft Iron, Low Carbon Steel, Stainless Steel 304, Stainless Steel 304L, Stainless Steel 316, Stainless Steel 316L, Stainless Steel 321, Stainless Steel 347, Stainless Steel 410, Aluminum, Copper, Brass, Nickel 200, Monel 400, Inconel 600, Hastelloy B2, Titanium (see more ring joint gasket specifications in our products catalog)

In the high-pressure pipeline connections, the lens pad sealing structure has a wide. The sealing surface of the lens pad is a spherical surface, which is in contact with the conical sealing surface of the pipe. The initial state is a circular line. Under the action of the pre-tightening force, the lens pad is plastically deformed at the contact point, the ring line becomes an endless belt, and the sealing performance is better. Because the contact surface is naturally formed by the spherical surface and the inclined surface, the gasket is easy to center.

Features:

  • High temperature and high-pressure resistance, suitable for high-pressure flange;
  • Durable and reliable seal;
  • Adapt to the working conditions of pressure and temperature fluctuation

GINSEAL lens gasket is a line contact seal for use in high-pressure piping systems and in pressure vessel heads. The lens cross-section is a spherical gasket surface and requires special machining on the flanges. Since the contact area is very small and gasket seating pressures are very high, the gaskets will seat with a small bolt load. Normally the gasket materials should be softer than the flange. In ordering lens gaskets, complete drawings and material specifications must be supplied.
Most popular metal lens gaskets are manufactured according to the standard of DIN 2696, from this standard, we can provide lens gaskets with dimensions from DN10 PN63 up to DN300 PN400.

Besides DIN 2696, there are also other standards that describe particular shapes and dimensions in detail.
Ginseal also provides non-standards lens metal gasket based on the provided drawings.
Unlike Ring type joint gaskets, Lens gaskets are reusable, as the sealing effect is generally achieved by elastic deformation of the surfaces.

Details About Lens Gaskets

  • Item No.: JSG-RJL
  • Lens gaskets are normally used as high-pressure gaskets.
  • Lens gaskets are stress-resistant.
  • The seating area of the lens assembled in the turned flange groove
  • Increases by increasing bolt load.
  • One disadvantage, however, is that under high pressure and
  • Temperatures, the circumference of the gasket lens may bulge which
  • This leads to loss of initial load.
  • Other designs are available on request.

PTFE Enveloped Non Asbestos Gasket https://www.ginseal.com/ptfe-enveloped-non-asbestos-gaskets/ https://www.ginseal.com/ptfe-enveloped-non-asbestos-gaskets/#respond Thu, 16 Apr 2020 05:39:46 +0000 http://ginseal.seowaimao.com/?post_type=product&p=1125 Ginseal, one of the leading PTFE envelope gasket manufacturers from China, has been involved in sealing gasket manufacturing for over 20 years.

Polytetrafluoroethylene envelope gasket,also named PTFE envelope gasket, Teflon envelope gasket, is a non-metallic gasket, generally composed of two parts: the envelope and insert. The envelope layer mainly plays a role in corrosion resistance and usually made of polytetrafluoroethylene. The insert (filler) is a non-metallic sealing material with or without a metal reinforcement layer with good elasticity.

The envelope gasket is divided into V type, U type and L type according to the different inner core structures. Some containers, pipes, and valves in the petroleum, chemical, pharmaceutical and food industries are often connected with PTFE gaskets to ensure clean materials. PTFE envelope gaskets are widely used in the sealing of various strong acids, strong alkalis, strong oxidation, chlorine and non-contaminated media

Ginseal PTFE gasket provides excellent sealing in corrosive environments. Combining the low friction and chemical stability of PTFE with the mechanical strength of the gasket material, GINSEAL PTFE envelope gasket provides the user with a gasket that can be used confidently with aggressive media which would attack many other materials.

Temperature:
Up to +250oC (depending on the gasket material used).

Applications:
Glass lined pipe systems, distillation columns and reactor vessels where
Non-contamination is essential.

Please feel free to talk with us about PTFE envelope gasket specifications.
