Metal Gaskets

Metal Gaskets: Products

Spiral Wound Gaskets

Spiral wound gaskets combine the ease of sealing of a graphite, PTFE or mica filler with the strength afforded by a specially profiled metallic, spring-like reinforcement. The sealing element is manufactured by interleaving plies of alternating metallic winding strip and filler to create a gasket that is robust and easy to install.

Spiral wound gaskets can be manufactured from a wide range of metals to resist against chemical attack and temperature related degradation and used in combination with either graphite, PTFE or mica filler. Available in ASME and DIN standards with other standards available upon request.

Creates a very leak-tight, reliable seal.
Suitable for high temperatures and pressures.
Can be manufactured to suit standard flanges and also custom-designed vessels.

Ring Joint Type Joints

RTJs are designed to be used in high pressure applications and can be manufactured from a number of materials to suit the process media and the flange materials.

RTJs are precision machined metallic rings which are designed to be used with API 6B, ASME B16.5 and API 6BX (dependent on the gasket style) flanges. RTJs are often used in offshore applications and certain styles can be adapted for subsea installation.

Universal Gaskets can hold a large range of RTJs in stock in a number of profiles and materials.

Can be used for high pressures.
Wide range of materials available.

Available ring joint styles, designed for specific flange types:

Style R Oval
Style R Octagonal
Style RX
Style BX

Jacketed Metal Gaskets

The most basic type of semi-metallic gasket has a compressible insert enclosed within metallic jacket. The insert material forces the metal to deform to suit the flange surface and effect a seal.

Metal jacketed gaskets are commonly used in heat exchangers though are often replaced by Maxiprofile style gaskets. Metal jacketed gaskets can be manufactured with a number of metals and high temperature fillers.

Can be manufactured to suit narrow flanges

Kammprofile

Kammprofile grooved, covered metal gaskets consist of a serrated metallic core with a soft facing material. The Kammprofile style gasket is mainly used in vessel applications where often the gasket width is limited. Kammprofiles are also often used as an upgrade on applications currently using metal jacketed gaskets due to the improved leak tightness, ease of installation and the possibility of reuse.

The depth and profile of the groove is specially design to facilitate densification of the facing material and create a very leaktight seal with low gasket stresses.

Kammprofile gaskets are often used in heat exchangers and can be manufactured with many bar configurations. Kammprofile gasket cores can also be refurbished and reused.

Low sealing stress required for installation.
Suitable for a range of chemicals.
Suitable for use in high pressure and high temperature applications.
Can be refurbished and reused.
Can be manufactured to suit standard flange applications and vessels.
Can be manufactured for use with narrow flanges.

Corrugated Metal Gasket

Corrugated Metal Gasket consists of a corrugated metallic core encapsulated by a graphite coating. It has been designed to seal on low load applications previously designed for Spiral Wound gaskets such as 150 and also 300lb lines.

A robust and easy to handle gasket, the corrugations in the core develop high stress areas to produce a gasket with excellent gas-tightness at low bolt loads.

Seals on low load applications.
Available in a range of core materials – the standard being Stainless Steel 316
