Freudenberg Oil & Gas Technologies is a global provider of innovative sealing solutions and products to the upstream oil and gas industry. We provide a full range of solutions that include elastomeric seals, engineered thermoplastic seals, metal seal rings and high integrity connector solutions for demanding offshore and subsea applications.
Through our facilities in Norway, formally known as Vestpak, we provide manufacturing and project engineering, sales and service support for all Freudenberg Oil & Gas product lines. Additionally, we provide Norwegian operators local inventory support of standard industry ring joints and gaskets.
Soft cut gaskets are a group of gaskets for general service. The fibres can be aramid, glass fibre, carbon or inorganic material. Common for all is that the fibres are bonded together with other filler materials and encapsulated with an elastomeric binder (NBR,SBR etc.).
The gaskets may have different temperature and pressure ranges.
Graphite is used very often as a packing material. Expanded graphite is used in production of flat gaskets and packings. This material is produced in a special process where natural graphite is expanded under extremely high temperatures after mixing with chemicals. After removing the chemicals again, the expanded flakes are then pressed into sheets or rolled to a defined density of, e.g. 0.7 or 1.0 g/cm3. The foil may be used as filler material in spiral wound gaskets or as a seal in serrated gaskets.
The temperature range is –200°C to +450°C. This packing has excellent chemical resistance and has neither cold nor hot flow. As the material is already millions of years old, it has no ageing problems.
PTFE is used where extreme resistance is required to seal against toxic and highly corrosive media.
PTFE is almost totally chemically inert and is only attacked by molten alkalis, metals and certain fluorine compounds at elevated temperatures. Suitable for sealing corrosive chemicals such as Hydrochloric acid, nitric acid, chlorine gas and applications in the food and pharmacautical industries.Temperature range up to 250 C.
Garlock GYLON® gasketing is a truly superior and unique material. The exclusive properties of GLYON gasketing are combined to deliver its superior performance to comply with today's clean air requirements through sealability and torque retention.
Asbestos-free GYLON gasketing routinely out performs all conventional PTFE products by drastically minimizing gasket creep and cold flow problems.
Typical conditions for GYLON gasketing are found in the food, chemical, petrochemical, pulp and paper plants and pharmaceutical industries
Gasket sets for insulating flanges are used to protect the flange from corrosion in places where a seal is required between flanges made from different metals. The three most commonly used ones are Pikotek, Phenolic and PUR.
The sets are used for electrical insulation of pipeline sections, to control cathodic protection and prevent the flow of electrostatic charges along pipelines.
Vestpak supplies three standard types of gasket sets for insulation: to fit flanges with an elevated surface, straight surface and ring grooves.
Pikotek manufactures both high- and low-pressure insulating gaskets for the following standards: ANSI B16.5, B16.47 A & B, API 6A, DIN, BS, AS and others.
