3 Over the years, our products have gaineda reputation for quality, reliability andtechnology that is second to Engineering SolutionsOur Application Engineering, ProductionEngineering and R&D teams work closely together to design, develop andmanufacture bespoke sealing solutions. We have been responsible for a numberof truly revolutionary products, includingThermiculite , Sigma and the FlangeRescue Gasket, which ensure we areable to continually meet the ever morestringent requirements of our SafeOver the last century, our aggressiveR&D efforts have helped customersbecome Flexitallic Safe. From the firstSpiral Wound Gasket in 1912 to the everevolving applications for Thermiculite ,our goal is to develop materials thatpush the parameters of heat, pressureand chemical resistance. Our Commitment to QualityWe place great emphasis on maintaininginternational quality standards,and are approved to ISO 9001:2008, ISO 14001:2004 and OHSAS 18001:2007,API 6A and API 17D, to ensure we meetthe highest possible standards for all our products and also invest heavily in test and quality assurance equipment to maintainour reputation for the highest materials are subjected to a widerange of tests as specified by statutoryregulations and customer approvals enable our customers to make informed choices as to thesuitability of a product for each andevery metallic RingType Joint is used in the petroleumindustry, where highpressure applicationsnecessitate the needfor a high TYPEJOINTSM aterialsThe gasket material should be selected to suit the service conditions.

6 Ring Type Jointsmanufactured to ASME are permanently marked according to standard. Each Ring Type Jointmanufactured to an API standard is identified by lowstress stamping with style, ring number, API licensenumber, material reference, Product Specification Level4 (PSL-4), a unique Flexitallic material identificationnumber, and month and year of manufacture. Such fulland comprehensive traceability, from material sourcewith mill certification to final supply, is an essentialingredient of the company s strict quality assuranceprocedures and exceed those demanded by the highestAPI 6A and 17D R The Ring Type Joint was initiallydeveloped for high pressure/temperatureapplications found in the petroleumindustry and is primarily used in the oil field on drilling and completionequipment.
