AWWA C227-22 Bolted, Split-Sleeve Couplings, 2022
- Foreword [Go to Page]
- I. Introduction. [Go to Page]
- I.A. Background. This standard describes bolted, split-sleeve couplings used to join pipe. It also includes materials of construction, inspection, and testing. These couplings have been used on water pipe since 1981. [Go to Page]
- I.B. History. In October 1999, the AWWA Standards Council authorized the AWWA Standards Committee for Steel Pipe to develop a new standard for the use of bolted, split-sleeve couplings for plain-end pipe. The first edition of that standard was approved by [Go to Page]
