Metallic / Semi-Metallic Gaskets

ECO SEAL – Low Emissions Spiral Wound Gasket

The standard spiral wound gasket exceeds all existing specifications and corresponding leakage requirements. Further engineered is a spiral wound gasket that is up to 10x tighter than the regular spiral wound gaskets. The KLINGER ECO-SEAL gasket has been manufactured in accordance to ASME B16.20-2017 and requires minimal alternations to your specification whilst reducing your plants fugitive emissions.
The concept behind Eco-Seal is not just a tighter gasket, its being able to quantify a reduction in plant emissions. Whilst other manufacturers may look to promote leakage rates of their spiral wound gaskets through gasket industry tests such as EN13555, KLINGER UK are going further. We can provide you with data that you can understand and can relate to. When in combination with KLINGER INTEGRITY SERVICES, we can offer you the complete emissions reduction program from gasket, installation, testing and recording.
Features:
High density construction resulting in increased mechanical stability.
Modified winding strip form
High quality graphite filler
Controlled filler protrusion

Maxiflex Spiral Wound Gasket

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.
Maxiflex 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.
Properties of Maxiflex
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.​

 

Maxigraph Corrugated Graphite Gasket

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

 

Maxiprofile Kammprofile Gasket

 ​

Maxiprofile grooved, covered metal gaskets consist of a serrated metallic core with a soft facing material. The Maxiprofile style gasket is mainly used in vessel applications where often the gasket width is limited. Maxiprofiles are also often used as an upgrade on applications currently using metal jacketed gaskets due to the improved leaktightness, 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.
Maxiprofile gaskets are often used in heat exchangers and can be manufactured with many bar configurations.
Maxiprofile gasket cores can also be refurbished and reused.
Properties of Maxiprofile:
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.

 

Metal Jacketed 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.
Properties of Metal jacketed gaskets:
Economical.
Can be manufactured to suit narrow flanges.
Range of materials available.​​

 

Ring Type Joints (RTJs)

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.
KLINGER hold a large range of RTJs in stock in a number of profiles and materials.
Properties of RTJs
Can be used for high pressures.
Wide range of materials available.​​
