IN STOCK AND READY TO SHIP: SIGMA’s 3-36” SIGMAFLANGE™ Universal Model SFUP
— Accommodates Pipe Misalignment and Facilitates Maintenance —
SIGMA is pleased to announce the ready availability of its SIGMAFLANGE™ Universal pack Model SFUP in sizes 3-36”. SIGMA continues to lead the industry in designing and developing innovative restraint installations for larger diameter pipes (sizes 54" through 64" for ductile iron pipes and 54" through 60" PVC pressure pipes).
The SIGMAFLANGE™ Universal is designed to connect plain-end ductile iron, steel, AWWA C900 PVC, C909 PVC, ASTM D2241 PVC, and HDPE pressure pipes to a variety of flanged fittings, pipes, valves, and other flanged-end connections. A ductile iron adapter ring provides proper sealing of the adjacent flange outlet using an O-ring gasket while accommodating necessary pipe-end restraint using a SIGMA ONE-LOK™ Model SLGU wedge-action gland for the six different pipes listed above.
Benefits of the SIGMAFLANGE™ Universal Model
The innovative design of the SIGMAFLANGE™ Universal brings several benefits for flanged-end connections, as Satheesh Chandrasekaran, Pipe Restraint Product Engineer, explains: "The SIGMAFLANGE™ Universal allows for a great deal of flexibility in the field for flanged-end connections for municipalities and construction engineers. The SFUP offers multiple benefits including:
Accommodating pipe misalignment
Readily facilitating service and maintenance
Providing a 2:1 factor of safety based on the rated pressure of the pipe
Improved compression and sealing.
This capability is useful for contractors or engineers working on new construction or Treatment Plant rehabilitation projects as this allows the contractor to use a single robust restraining mechanism, the SIGMAFLANGE™ Universal, for various pipe types.
The SIGMAFLANGE™ Universal is electro-deposition coated with a topcoat black enamel and currently available in sizes 3” through 36” with 42” & 48” under development.
