WHN YOU ND from OKRING okring Technology, C offers a patented, permanent, axially swaged tube fitting. This technology for medical gas applications has been approved by NFP 99-005 (Paragraph 5..0.7 (4)). Imagine being able to shut down your medical gas system and within minutes being able to install a tie-in, a tee for future expansion or to cap off a line for renovation. Medical gas tie-ins can be installed as fast as you can drain the lines. Simply bleed the medical gas or vacuum line, cut and clean the tubing, and install a OKRING fitting. It takes less than five minutes to install a permanent, leak-tight fitting. Since no brazing is necessary, no expensive nitrogen NF purge is required. Without brazing, no particulate is created during installation. Gas lines go back into service as fast as the credentialed Medical Gas Verifier can document proper concentrations. okring Medical Gas s... The installation of OKRING Medical Gas fittings takes minimal time and there is less patient disruption due to noise and brazing. okring installation is a cold braze alternative. There is no hot work, no burn permits, and no fire watches necessary. In addition, the speed of the OKRING installation reduces system down-time and the additional costs associated with contract labor and overtime staffing. s are cleaned for oxygen service in sizes 3/8 through. simple hand held tool is all that is necessary. The top photo on the right shows an installer attaching a ½ OKRING coupling to a pre-fabricated, vacuum line tie-in. The oxygen tie-in installation in the middle & bottom photos uses OKRING ½ couplings on Type copper tubing. The cost of OKRING Medical Gas s is considerably less than the overall cost of other special fittings for medical gas tie-ins. short training course is all that is required for contractors with NSI/SS 600 installer certification. okring Technology has been used by the Marine, Biotech, utomotive, Power Generation, Chemical Processing and Railroad industries worldwide since 989.
dvantages of OKRING s No brazing necessary No nitrogen NF purge required No danger of particulate formation No danger of melting or burning of ambient materials in the area (such as adjacent wiring and pneumatic lines) No burn permits needed No fire brigade standby necessary No shutdown of smoke or fire sensors in the area No cooling of brazed joints -- immediate usage following leak test Minimal patient disruption Special configurations available This outside installation used OKRING couplings to connect existing medical gas lines to new lines for hospital expansion. This installation included ¾ size for nitrogen and nitrous oxide. The oxygen line was ½ size on Type copper. The total installation time for the three fittings was 0 minutes. OKRING s SP (lastic Strain Preload) Technology The leak-free seal is the result of OKRING s SP installation where the axial movement of the OKRING driver over the body swages the body onto the tube s surface. This compresses the tube wall first elastically and then plastically. BTTR CONNCTION The tube wall resists this swaging action, generating high unit compressive loads at the contact points between narrow sealing lands inside the fitting body and the tube surface. These contact stresses are sufficiently high to plastically yield the tube surface under the sealing lands, forming a 360 circumferential, permanent, metal-to-metal seal between the tube and fitting body. The driver, which experiences a small increase in diameter (elastic strain) during installation, exerts an elastic, radial preload on the metallic seals for the life of the connection. Pressure Testing This test was performed on ½ Type K copper tubing. s shown, the copper tubing burst at 300 psi while the fitting remained intact.
