SIGMA remains proactive in bringing new technology for the proper restraint of both ductile iron and PVC pressure pipelines. Eleven years ago, SIGMA pioneered the first-ever restrained joint devices for AWWA C905 PVC pressure pipes in sizes 42″ and 48″. We are constantly developing innovative solutions to today’s ever growing demand for pipeline restraint. These new products enhance our complete and extensive range of ductile iron fittings.
