The BS and BSI gaskets are specifically designed tobe used in those applications where a low bolt torque is required. Traditional spiral wound gaskets have the steel winding protruding above the compression stop.BS and BSI gaskets instead have the fil ler materialprotruding above the metal winding and the guide ring.This results in a perfect sealability achieved with a lowerloading stress compared to tradional spiral wound gaskets.

The HT gaskets are specifically designed to be used at extreme temperatures and in presence of oxidizing environments.The construction includes special HT Inconel X750 windings and rings combined with Flexigraf® fil ler protected on inside and outside diameter by a heat and oxidation resistant Micatherm fil ler.

NOSE RI Gaskets with spiral wound outer ring are primarily designed for TEMA male and female flanges and are custom built to suit the design conditions of individual heat exchanger vessels. These gaskets are available in an extensive range of materials.The external nose ensures the correct location of the spiral wound sealing element which is protect by an internal ring, used also as a compression stop.Nose RI gaskets are available also with solid metal or metal jacketed pass bar configuration.

CARRIER gaskets consist of a solid steel ring with machined recess in each faces where spiral wound gaskets are located. This results in a higher recovery gasket which ensure that the bolt torque is maintained even in presence of hard pressureand temperature cycles. Typical applications arepower genertion, petrochemical and nuclear industries.Carrier gaskets can be used on flat face, raised face or tongue and groove type flange, as well as non standard flange configurations. They can be supplied for both small and large diameter nominal bores up to class 2500 pressure rating. Carrier gaskets are also tailor made to suit specific flange arrangements and design conditions.

One gasket accommodates both Class 150 and 300 flanges. Multi-Class Gasket features are as follows:• One gasket accommodates both Class 150 and 300 flanges, available pipe size 1/2” – 24” (Class 150 to 600 in NPS 1/2 through NPS 3).• Reduced inventory requirements.• Easy to install: less than half the studs need to be removed to change the gasket.

FMI Flexcamm® cammprofile gaskets are recognized as a new high quality sealing alternative. These gaskets are used as problem solver when there is a difficult sealing environment and performance are critical at low seating stresses. Flexcamm® gaskets consist of a metal core with concentric grooves with sealing layers made of flexible graphite Flexigraf®, expanded mica Micatherm, conventional ptfe or bidirectional ptfe Sichem®.Metal core is usally selected based on metallurgy of the piping. Flexcamm® are manufactured in different materials and non-circular shapes with extremeaccuracy. They can also be custom engineered to fit various applications.

Manufactured without a guide ring for tongue and groove, or recessed flange applications such as male and female. It is typically used in heat exchanger applications and applied as an upgrade to double jacketed gaskets.

SRG gasket is a solid gasket made by a rigid metal core with two expanded graphite layers bonded to each face. Solid core provide protection against blow out whilst soft graphite layers provide an excellent seal dueits high conformability into the flange faces even under low applied seating stesses. It is possible to use awide range of core materials, from carbon steel to exotic alloys. SRG gasket finds applications in chemical andpetrolchemical plants for Low pressure heatexchangers, narrow land width, non circular shapes.

Constructed with an integral guide ring for aligning purposes. It is suggested to be used in raised face flanges. The gasket is typically designed and sized per EN12560-6 spec for ASME B16.5 flanges, but can be manufactured to fit other standards.

S T Y L E F A

Constructed with a lose guide ring. This solution is recommended in application with excessive radial shear characteristics, thermal cycling, and expansions. The gasket is typically designed and sized per EN12560-6 spec for ASME B16.5 flanges, but can be manufactured to fit other standards.

RTJ gaskets are produced in different solid metal types. They are used for high pressure (ti l l 1300 bar) and for high temperature (ti l l 1000°C) and are used where corrosive agents are presents.These gaskets are obtained by meccanical working from forged or laminated metals. RTJ find their mainly application inrefining process in crude extraction and in high pressure applications.For their production we use the last edition of the API standard.FMI can supply oval and octagonal ring joint, BX and RX for allapplications to suite the flanges design with standardand special styles.
