1 Piping Materials Plumbing Systems CNST 305 Environmental Systems 1 Dr. Berryman 1bIntroduction – MaterialsChapter 1, 3; Appendix D (Wentz) and (Tao) 4.39 Building Codes and Standards (2 hrs); 4.44 Notes and specifications, reference conventions (1 hrs)

2 Material Selection Criteria Corrosiveness Temperature Pressure Material allowed by code Availability Cost of material/installation Miscellaneous Noise Combustion

3 Steel (carbon) Pipe Types Black Galvanized Cast Iron Connections Tapered Thread or Threaded* Flanged Grooved Welded Sizes/Weight Schedule 40*, 80, 120 Nominal I.D. used for measure (ie ¾” =.82 inches; O.D. = 1.0 inches) Cast iron – SV* and XH Fittings Elbow, couplings, union, wye, street L, reducer, dielectric, 90 o L, etc. *most commonly used

4

5 Cast Iron

6 Copper (nonferrous) Types Tempered hard or soft Connections Soldered (sweated)* Flanged Compression Sizes/Weight K – heaviest with green stripe L – medium weight w/ blue stripe M – lightest w/ red strip* DWV – yellow stripe (non pressure) Measured O.D. Fittings Elbow, couplings, street L, reducer, dielectric, 90 o L, Tees, etc. *most commonly used

7

8 Plastics (polymers) Types ABS, CPVC*, PB, PE, PP, PVC*, PVDF, Fiberglass Connections Solvent weld* Flanged (plastic) Compression Sizes/Weight Schedule 40*, 80 or 200 psi Fittings Elbow, couplings, street L, reducer, dielectric, 90 o L, Tees, etc.

9

10 Stone-Based Types Concrete Clay Glass Connections Compression (neoprene gasket or O- ring) Concrete grout Sizes/Weight Diameters (ie up to 144” for concrete) Fittings Elbow, reducers, couplings, hub and spigot, etc.

11 Valves Butterfly Check Gate Globe Ball

12 Terminology Riser Vertical water supply piping supplying more one floor or more Stack Vertical DWV piping (exceptions vertical fixtures and vented stacks…ie stack vents, vent stacks) Branch Horizontal piping (water and DWV) for plumbing other than a riser, main or stack Main Principal pipe supply for connecting branches

13 Terminology (cont.) Vent Lines Soil Lines Traps Air Gap/Break Prevents back sophoning Flush valves have air breaks Flushometers (flush valves) Sump A tank or pit that receives liquid wastes Grey water

14 Terminology (cont.) Potable Water Water Service From water main Water Distribution Service Water piping within the building to point of usage Water Supply System All water pipes, fittings, control valves, etc. within and adjacent to building

15 Next Time Waste Water Disposal and Storm Drainage Chapter 4, 7; Appendix A (Wentz) and (Toa)
