Insulating sets are essentially used for pipeline flange corrosion protection, where a seal is required between dissimilar flange materials. The use of dissimilar metallic flanges with a conductive gasket material accompanied with a suitable electrolyte may set up a galvanic cell which will corrode the anodic metal. Insulating sets are also used to electrically isolate flange joints, preventing the flow of electrostatic charge along pipelines.
There are three standard Types of insulating sets available to suit raised face, flat face, and ring grooved flanges, as illustrated below.
FLIPS India Engineering Insulation Gaskets For Type "F" Raised Face Flanges In this type, the central gasket is designed to be located inside the flange bolt circle and sits fully on the raised face porting of the flange. This type of gaskets will be supplied in all the materials shown in Table
FLIPS India Engineering Insulation Gaskets For Type "E" For Full Face Flanges In this type, the central gasket has its outside diameter as equal to that of flange outside diameter and precision cut bolt holes. This design helps easy alignment of the gaskets during installation. Type "E" gaskets are available in Neoprene faced reinforced phenolic material or other materials in Table.
FLIPS India Engineering Insulation Gaskets For Type "D" For Ring Joint Gaskets In this type the gaskets available in fabric reinforced Phenolic. Available in basic "Oval & Octagonal" type. This type has the contact faces with oval shape. It provides a high reliability seal. These gaskets comply with ASME B - 16.20.
The Kammprofile is the preferred gasket when needing improved performance at low seating stresses. It features excellent anti-blowout properties associated with the reliability of a solid metal-to-metal seal combined with soft sealing face to ensure a tighter joint. Kammprofile is an ideal replacement for problem applications associated with jacketed gaskets.
Design Features Fabricated in nominal pipe size and pressure Configured in standard shapes for heat exchanger application Available with centering ring for use on raised face flanges Metal cores available in soft iron, stainless steel and exotic materials Standard surface materials of flexible graphite or PTFE Low seating stress Optimum combination of solid core with soft sealing face

Permits a tighter joint under operating conditions Results in reduced emissions Compensates for fluctuating ranges of temperature and pressures Manufactured for all flanges including class 150# to class 2,500# Easy to install and effortless to remove Improves plant efficiency Maintains a tight seal over variable range of bolt stresses
Standard Styles Style G-PN Style G-PN Kammprofile gaskets are selected for use in confined locations, including male and female, tongue and groove, and recessed flange arrangements.
Style G-ZG Variation of the G-PN Kammprofile, utilizing an integral outer locating ring for correct gasket positioning within the mating flange bolt circle. Style G-ZG Kammprofile gaskets are recommended for use on standard raised face and flat face flange assemblies.
Style G-ZA The Style G-ZA Kammprofile is a slight variation of the Style G-ZG. The integral outer locating ring is replaced by a loose fitting independent ring which is preferred where flange differential radial thermal expansion may be encountered. These rings may also be spot welded.
A Metal Reinforced Gasket is a rigid laminated gasket consisting of soft layers bonded to each face of a solid metal core by a high temperature/chemical resistant synthetic bonding agent. While the solid metal core prevents gasket blowout, it provides high strength and rigidity: and the soft facings provide an exceptional seal. The soft facing material flows easily into the flange faces allowing a high integrity seal, even under low applied seating stresses.
The metal core material is selected to suit the application design conditions and the media to be sealed. A wide range of core materials are available, from the relatively low cost carbon steels, through the range of stainless steels up to the "exotic" alloys. For chemical resistance and temperature stability purposes, the correct core material must always be selected.
Standard core material is 316 stainless steel, and standard core thickness is 1/8".
The soft gasket facings can be Flexible Graphite, PTFE, Compressed fiber gasket material. However, Flexible Graphite is the standard and most widely used facing material supplied with the MRG gasket.
Suitable up to pressure Class 300, the Metal Reinforced Gaskets is widely used in the chemical and petrochemical industries, where a high temperature/corrosion resistant, high integrity joint is required.
flips india engineering can manufacture & supply variety of cut shapes or gasket sheet material in sheets or rolls. A "soft gasket" is a term used when referring to a gasket that is easily compressed under a low bolt load. Soft gaskets are used in a wide range of applications from pipe flange, heat exchanger, compressor and bonnet valve gaskets to name just a few. A soft gasket can be selected from a large variety of rubbers, ptfe, graphite, and compressed asbestos & non-asbestos sheet products.
we are pleased to supply soft gasket material & gaskets made out of following soft gasket materials:
A Lens Type 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. In ordering lens gaskets, complete drawing and material specifications must be supplied.
Delta Gasket A delta gasket is a pressure actuated gasket used primarily on pressure vessels and valve bonnets at very high pressures in excess of 5000 PSI. As with the lens gasket, complete drawings and material specifications must be supplied. Internal pressure forces the gasket material to expand when the pressure forces tend to separate the flanges. Extremely smooth surface finishes of 63 microinches or smoother are required when using this type of gasket.
Bridge-Man Gasket The bridge-man gasket is a pressure activated gasket for use on pressure vessel heads and valve bonnets for pressures of 1500 PSI and above. The cross section of the gasket is such that internal pressure acting against the ring forces it against the containing surface making a self-energized seal. Bridge-man gaskets are frequently silver plated or lead plated to provide a softer surface and minimize the force required to flow the gasket metal into the flange surface.
Weld Gasket Another gasket concept with origins from the German industrial market are weld gaskets. As standard, two variants exist; Weld Membrane Gaskets in accordance with DIN 2695 and Weld Ring gaskets.
Weld Membrane Gaskets The Weld Membrane Gasket consists of two similar rings each of 0.157" (4mm) thickness. For chemical compatibility and in order to ensure controlled thermal conductivity and weld compatibility, the gasket material must always be the same as the flange material. Each ring is individually welded to its mating flange. Upon flange assembly, a second welding operation joins the two rings at their outer diameter which provides for a fully welded joint. Weld Ring Gaskets As with Weld Membrane Gaskets, Weld Ring Gaskets are used in pairs. As standard, each ring is manufactured to similar materials to that of the flange, thus ensuring full compatibility. All welding is conducted on the outside of the gasket and flange, thus ensuring ease of location, especially in restricted applications where space is limited. Two styles exist, Style SR and Style SRL. Style SRL is recommended when there is flange differential radial expansion.
Rtj (ring type joint) gaskets are manufactured in accordance with api-6a and ansi b16. 20 specifications. Rtj's have "r" numbers assigned to them for pipe size and pressure class identification. Stock materials include soft iron, low carbon steel, 4-6 chrome (f5), 304, 304l, 316, 316l, 347, monel, inconel and incoloy.
api ring joint gaskets api ring joint gaskets come in two basic types, an oval cross section and an octagonal cross section. These basic shapes are used in pressures up to 10,000 psi. The dimensions are standardized and require specially grooved flanges. The octagonal cross section has a higher sealing efficiency than the oval and would be the preferred gasket. However, only the oval cross section can be used in the old type round bottom groove. The newer flat bottom groove design will accept either the oval or the octagonal cross section. The sealing surfaces on the ring joint grooves must be smoothly finished to 63 microinches and be free of objectionable ridges, tool or chatter marks. They seal by an initial line contact or a wedging action as the compressive forces are applied. The hardness of the ring should always be less than the hardness of the flanges.
bx and rx ring gaskets the bx ring gasket differs from the standard oval or octagonal shape in that it is square in cross section and tapers in each corner. Bx can only be used in api 6bx flanges. Rx ring gaskets are similar in shape to the standard octagonal ring joint gasket but their cross section is designed to take advantage of the contained fluid pressure is effecting a seal. They are both made to api 6a.
special ring type joint gasket for critical and non standard applications, where ring type joints are unsuitable in their standard form, flips india engineering offers a range of specialized ring type joint gaskets to suit the needs of the petrochemical industry.

type cgi suitable for use with flat face and raised face flanges and specified for high pressure/temperature service or where corrosive or toxic media are present. Note on use of inner rings: asme b16. 20 which covers spiral wound gaskets requires the use of solid metal inner rings in pressure class 900, nominal pipe sizes 24" and larger, pressure class 1500, nominal pipe sizes 12" and larger, pressure class 2500, nominal pipe sizes 4" and larger, all ptfe filled gaskets
type he type he gaskets are used for heat exchangers where pass bars may be required. The outer portion is of standard spiral wound construction, whereas the rib partition is normally of single or double jacketed type, securely fastened to the i. D. Of the spiral wound portion.
type he-cg this type is identical to the type he, except that it is fitted with an outer guide ring.
type he-cgi with spiral wound outer ring the type he-cgi is a variation of the type cgi spiral wound gasket, developed for use on heat exchanger tema type flange arrangements. In conjunction with an inner ring, the standard spiral wound construction also supports an outer wound steel nose, designed for the purpose of accurate gasket location. It is also available with solid metal outer ring.
type cg-rj this type designates a specially sized cg gasket to be used on standard ring joint flanges. The outer ring is dimensioned to cover the ring joint grooves and to prevent the spiral wound portion from entering the groove. This type of gasket should be used only as a maintenance repair item.
