AWWA C230-11 Stainless-Steel, Full-Encirclement Repair and Service Connection Clamps (PDF)

This standard describes fabricated full-encirclement stainless steel band clamps for use in the repair or service connection of potable water, wastewater, and reclaimed water piping systems. They are intended for pipe sizes 2 in. (50 mm) through 12 in. (300 mm). Full-encirclement repair clamps shall be manufactured completely from stainless steel or a combination of stainless steel band and cast ductile-iron lug, along with stainless or low-alloy carbon steel bolts and nuts, depending on service requirements and the purchaser's documents. Tapped service connection outlets may be provided and shall range from 1/2 in. through 3 in. (12 mm through 75 mm) sizes, with either NPT- or AWWA-type threaded connections. This standard does not cover stainless steel tapping saddles whose seal is not fully circumferential. Repair clamps for larger than 12-in. (300-mm) diameter pipe are available from various manufacturers but are not covered by this standard.
