Spiral Wound

Spiral Wound gaskets have become extremely popular due to a wide variety of available styles and sizes. Spiral Wound gaskets can be fabricated of any metal which is available in thin strip and which can be welded; therefore they can be used against virtually any corrosive medium dependent upon the choice of the metal and filler. They can be used over the complete temperature range from cryogenic to approximately 2000°F. This type gasket can be used in all pressures from vacuum to the standard 2500 psi flange ratings. They are more resilient than any other type of metallic gasket with the exception of pressure sealing metal gaskets and, as a consequence, can compensate for flange movement that may occur due to temperature gradients, variations of pressure and vibration. Spiral Wound gaskets can also be manufactured with variable densities, i.e. relatively low density gaskets for vacuum service up to extremely high density gaskets having a seating stress of approximately 30,000 psi. The softer gaskets would require a seating stress in the range of 5,000 psi.

Exchanger Gaskets

A "Heat Exchanger Gasket" is a term that has been given to the gasket that is called out for use in an exchanger. The make up of the gasket or type varies due to the operating conditions of the exchanger. Some of the commonly used gaskets are metallic and soft compressible material.

Construction of Metal Jacketed Gaskets - Metallic gaskets can come in different styles like; double jacket, single jacket, solid metal or a spiral wound. Soft compressible material can be rubber, PTFE, or non-asbestos compressed sheet type. The design of an exchanger also may require different gasket shapes and the ones mentioned above can be made to a variety of shapes.

Lamons jacketed gaskets are normally shipped with a non-asbestos high temperature filler. The standard filler is normally sufficient for applications up to 900° F. Other soft fillers are available for higher temperatures or special applications including Grafoil . Standard metals used to make jacketed gaskets, regardless of the type, are aluminum, copper, the various brasses, soft steel, nickel, Monel , Inconel and stainless steel types 304, 316, 321, 347, 410, 502. Obviously the choice of the metal used for the jacketed part of the gasket would depend upon the corrosive conditions being encountered.

Ring Joints

"RTJ" (ring type joint) gaskets are manufactured in accordance with API-6A and ANSI B16.2 specifications. 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. 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. 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.

Soft Gaskets

A " Soft Gasket" material is a term used when referring to a gasket material that is easily compressed under a low bolt load. This term has been used to distinguish the difference from a metallic gasket. A soft gasket material can be selected from a large variety of rubbers (neoprene, viton, SBR, EPDM, etc.), TFE, graphite, and compressed non-asbestos sheet products. 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. Soft gasketing material can be purchased in a variety of cut shapes or be provided in sheet or rolls.

CMG (Corrugated Metal Gasket)

Lamons Gasket Company's Corrugated Metal Graphite (CMG) is a high performance gasket for standard flange or heat exchanger applications. This gasket offers:

High sealability
Conformity where low bolt load is available
Maintains high bolt loads, upon re-tightening, in heat exchanger applications
Heavy gauge corrugated insert for support
Choice of insert metals

The CMG molds in place by filling in irregularities of the spaces creating a superior seal. It maintains the seal even in harsh environments including hydrocarbons and steam applications. You can specify CMG for applications where there is:

Low bolt loads or high available gasket stresses
Restricted area for flange separation making it impossible for a spiral wound type
A need to substitute compressed asbestos or non-asbestos gasket for a variety of applications

CMG-EX

Lamons CMG-EX gasket is a premium variation of Lamons original CMG gasket design. The CMG-EX was designed specifically for heat exchanger applications and offers the following benefits:
Highest level of sealability
Excellent flexibility in radial shearing forces, often found in heat exchangers
Maintains a seal upon retightening in heat exchanger applications

Kammpro

Engineering Design results in Improved Performance. The Lamons Kammpro 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. Lamons Kammpro is an ideal replacement for problem applications associated with jacketed gaskets.
