This seminar will review past and present standards, steel making, design, manufacturing, and installation over the past fifty years. STI/SPFA members will discuss several design topics including internal pressure, fittings including outlets and harnesses, buried pipe design including a review of soils, welding, and an introduction to steel pipe design for seismic. QA/QC will be reviewed and the STI/SPFA audit program will be covered. Improvements for each topic will be discussed and how that affects the current life expectancy of today’s steel water pipe.
