RING JOINT GASKETS
QUALITY WORLDWIDE
Dedication and commitment to innovative
technology and quality control ensures that DAN-LOC is the industry leader in machined seal technology. Quality is the emphasis from standard ring joint gaskets to specialized seals. DAN-LOC products are approved by the American Petroleum Institute to API specification 6A. Strict quality assurance procedures are applied throughout production - from receipt of raw material, through manufacture to delivery and with full material traceability. DAN-LOC has a quality system that adheres to the stringent requirements of ISO.
COMPREHENSIVE SELECTION AVAILABLE DAN-LOC's aim remains to meet the exacting demands of our customers. Speed of response is often crucial. To satisfy this need, a wide range of standard and non-standard Ring Joint gaskets are held in stock. Raw material stock levels are maintained to allow specials to be supplied on short lead times.
DEDICATION TO TECHNOLOGY
DAN-LOC's extensive investment in production
technology, with the use of the most up-to-date material handling and machining work centers, has ensured that we remain one step ahead of the competition. Improvement is a constant aim, with our experienced production engineers continually assessing and upgrading production techniques and equipment. DAN-LOC is committed to product advancement through continuous product evaluation and reappraisal. This offers the customer unrivalled service. Our in-house high integrity test equipment allows the constant development of a metallic gasket range to meet the ever-increasing demands for new sealing performance. DAN-LOC utilizes a state-of-the-art coordinate measuring machine (CMM) in our quality control operations. The CMM is used to verify critical dimensions on machined parts and gives DAN-LOC a competitive advantage in the marketplace. All DAN-LOC Ring Joint gaskets are manufactured from fully traceable materials and can be supplied to NACE specifications upon request. Each is low stress stamped with style, API license number, material reference and a unique DAN-LOC material identification number. Such full and comprehensive traceability, from material source with mill certification to final supply, is an essential ingredient in the company's strict quality assurance procedures and exceeds those demanded by API 6A .
MATERIALS The gasket material should be selected to suit the service conditions. It is always recommended that the gasket material be softer than the mating flanges. The popular ring joint materials with recommended maximum hardness and identification as specified in API 6A, are show in the table below. For more highly specialized applications, ring joints can be machined from DUPLEX steels and other exotic materials such as Monel®, Inconel® Incoloy®, and Hastelloy®.
* Measured with 3000 Kg load except soft iron which is measured with 500 Kg load. t Measured with 100 Kg load and 1/16 inch diameter ball. As with all metallic joints, the re-use of Ring Joint gaskets is not recommended. Work hardening of the material occurs during assembly and use. With subsequent re-use, increased bolt loads are required to achieve similar sealing performance. Flange indentations also may result. PROTECTIVE COATING In accordance with API specifications, soft iron and low carbon steel Ring Joint gaskets are protected with electroplated cadium to a maximum thickness of 0.0005”. Alternative material coatings can be supplied upon request.The Ring Joint gasket was initially developed for high pressure/temperature applications found in the petroleum industry and is primarily used in the oil fields on drilling and completion equipment. However today this product range can also be found on valves and pipework assemblies along with some high integrity pressure vessel joints.
