Gaskets

SNAGlobal supplied spiral wound gaskets are made of a preformed metallic strip and a soft filler material (PTFE or Flexible graphite), wound together under pressure, optionally with an inner and/or
outer guide ring. The metal strip holds the filler, resulting in excellent mechanical resistance, resilience
and recovery. The four most basic styles listed as follows:


Type GS
Utilises an external ring which accurately centers gasket on flange face, provides additional redial strength to prevent gasket blow-out and acts as a compression stop. A general purpose gasket suitable for use with flat face and raised face flanges. Above class 600 an internal ring is recommended.


Type GS-IR
This gasket is identical to the type GS , however an inner ring has been inserted to enhance the gasket performance, One of the advantages to adding the inner ring is to prevent the possibility of the gasket imploding into the pipe during installation and also has working advantages for higher pressures and or gaskets with PTFE filler.


Type S
Basic construction type, wound by steel tape and filler material. Suitable for tongue and groove or male and female or grooved to flat face flange assemblies.


Type S-IR
Solid inner metal ring acts as a compression stop and fills the annular space between flange bore and the inside diameter. Designed to prevent accumulation of solids, reduce turbulent flow of process fluids and minimise erosion of flange faces. Suitable for male and female pipe flange.

API ring joints come in two basic types, oval and an octagonal shape. These basic shapes are used in pressures up to 10,000 psi. RTJ's have "R" numbers assigned to them for pipe size and pressure class identification.

One of the key advantages in using the Camprofile is that with some refurbishment work the main gasket is reusable and when dealing with exotic alloys such as Monel, Incoloy, Titanium, Hastelloy etc the savings over a period can be substantial.

The Camprofile can be supplied as just the body suitable for recess and tongue and groove applications or with an outer ring fitting for use on standard flanges.


SNAGlobal Jacketed gaskets are used in a wide range of industries and service applications. The most common jacketed type is the Double Jacketed which is made from two pieces of metal with a soft filler or Non Asbestos, Graphite or Ceramic and is widely used for heat exchanger and vessel applications.

Second to the double jacketed is the single jacketed which are more commonly used when a narrow flange width gasket is required.

In addition to the round shape jacketed gaskets can also be produced as oval, pear and square.


SNAGlobal Flange insulation kits available in three types (see below), each kit comprises of one insulating gasket (either an oval ring type joint or flat gasket dependant on flange type.), one insulating sleeve per bolt, two insulating washers per bolt and two plated steel washers per bolt.

TYPE D
Type D gaskets are specifically designed to fit into the ring groove of ring-type-joint flanges. They are manufactured of a medium weave, fabric-reinforced phenolic material and are sized to ANSI specifications available in basic oval as well as octagonal shape. Also available are BX gaskets with pressure ratings to 15,000 PSI.

TYPE E
Type E is a full-faced gasket with the same outside diameter as the flange and precision cut bolt holes. This design facilitates proper alignment of the gasket during installation and foreign material prevented from shorting the flange insulation. Type E gaskets are available in plain face or Neoprene face Phenolic, as well as a variety of high temperature materials.

TYPE F
Type F gaskets are made to fit the raised face portion of the flange only. As there are no bolts holes in
the F gasket, the inside diameter of the bolt hole circle is slightly smaller than the outside diameter of
the gasket, assuring an exact, automatic positioning of the gasket. Available in the same materials as the type E gasket.


SNAGlobal supply a full range of CNAF (Compressed Non Asbestos Fibre) sheeting to cover all possible applications, the range starts with the commercial quality for sealing low pressures and temperatures up to the top of the range Carbon Fibre materials for high temperature applications service.

The range can also be supplied with wire reinforcements, Graphite or anti stick coated to suit client requirements.


SNAGlobal
offers a comprehensive range of virgin and filled PTFE products
such as sheet, gaskets, rods, tubes etc.


SNAGlobal supply a full range of Graphite sheeting covering the three standard
types of Plain, Adhesive bonded and Tanged bonded. Pure plain graphite is manufactured from exfoliated graphite flake and is produced through an extensive calendaring process to give a thin flexible foil with no binders or resins.


SNAGlobal supply a complete line of high performance packing for pumps, valves, and other rotating equipment.

Gland packings are manufactured in the following materials. Aramid fiber, Carbon yarn, Fibreglass, Flexible graphite, Graphite yarn, Metallic Packing, PTFE Fibre, PTFE/Graphite fiber, Acrylic fibre, Vegetable fibre packing.
