1 PowerPoint ® Presentation Chapter 6 Joining, Installing, and Supporting Pipe Plastic Pipe Joints Copper Tube Joints Cast Iron Soil Pipe Joints Steel Pipe Joints Installing and Supporting Pipe

2 Chapter 6 — Joining, Installing, and Supporting Pipe Personal protective equipment, including proper eye and skin protection, must be worn when working with cleaners, primers, and solvent cements.

3 Chapter 6 — Joining, Installing, and Supporting Pipe Primers are required for PVC and CPVC plastic pipe and typically contain a permanent dye or pigment that shows that the primer has been applied to the pipe and fittings.

4 Chapter 6 — Joining, Installing, and Supporting Pipe Solvent cement cure times will need to be adjusted, depending on outside temperature.

5 Chapter 6 — Joining, Installing, and Supporting Pipe Solvent cement softens plastic pipe and fittings, ensuring a tight joint when the pipe is forced all the way into the fitting.

6 Chapter 6 — Joining, Installing, and Supporting Pipe The proper preparation and installation techniques must be used to ensure watertight and airtight solvent-cemented joints.

7 Chapter 6 — Joining, Installing, and Supporting Pipe An expander tool is used to expand the end of PEX tubing manufactured using the Engel process.

8 Chapter 6 — Joining, Installing, and Supporting Pipe A crimping tool is used to compress the sleeve on PEX tubing manufactured using the silane or radiation process.

9 Chapter 6 — Joining, Installing, and Supporting Pipe Push-type PEX fittings connect PEX tubing by using an internal interlocking mechanism.

10 Chapter 6 — Joining, Installing, and Supporting Pipe The three techniques of heat fusion are socket, butt, and sidewall fusion.

11 Chapter 6 — Joining, Installing, and Supporting Pipe Electrofusion is the process of joining two PE pipes together using an internally heated coupling.

12 Chapter 6 — Joining, Installing, and Supporting Pipe Mechanical couplings joining two ends of PE pipe provide leakproof joints that also resist pressure.

13 Chapter 6 — Joining, Installing, and Supporting Pipe Capillary attraction draws molten solder into the gap between the copper tube and fitting.

14 Chapter 6 — Joining, Installing, and Supporting Pipe The pasty range is the working temperature range for a particular type of solder.

15 Chapter 6 — Joining, Installing, and Supporting Pipe Copper tube and fittings must be properly prepared and joined to ensure a leakproof joint.

16 Chapter 6 — Joining, Installing, and Supporting Pipe The proper brazing temperature is achieved when the fitting becomes dull red or the flux becomes clear.

17 Chapter 6 — Joining, Installing, and Supporting Pipe In the brazing process, heat is applied to the joint and a filler metal is used to fill the gap between the fitting and tube.

18 Chapter 6 — Joining, Installing, and Supporting Pipe Copper press fittings of 1/2″ to 2″ are installed without soldering by using a pressing tool to press the fittings together.

19 Chapter 6 — Joining, Installing, and Supporting Pipe Copper press fittings of 2 1/2″ to 4″ are installed without soldering by using a pressing tool and pressing ring to press the fittings together.

20 Chapter 6 — Joining, Installing, and Supporting Pipe The depth, width, and location of a rolled groove must be accurate to ensure a watertight joint.

21 Chapter 6 — Joining, Installing, and Supporting Pipe Copper rolled groove joints are used for aboveground potable water supply applications.

22 Chapter 6 — Joining, Installing, and Supporting Pipe A pi tape is used to measure the groove diameter of rolled groove pipe.

23 Chapter 6 — Joining, Installing, and Supporting Pipe A branch tee is extruded from the wall of copper tube using a T-drill fitted with a collaring head.

24 Chapter 6 — Joining, Installing, and Supporting Pipe An impact flaring tool can be used to flare types K and L copper tube.

25 Chapter 6 — Joining, Installing, and Supporting Pipe A yoke-and-screw flaring tool flares the end of copper tube to accept the end of the fitting.

26 Chapter 6 — Joining, Installing, and Supporting Pipe Compression joints consist of a compression fitting, compression ring, compression nut, and copper tube being joined.

27 Chapter 6 — Joining, Installing, and Supporting Pipe Lengths of no-hub cast iron soil pipe must be properly aligned and joined to create a leakproof joint.

28 Chapter 6 — Joining, Installing, and Supporting Pipe Compression gaskets provide a leakproof joint between the bell and spigot.

29 Chapter 6 — Joining, Installing, and Supporting Pipe NPT are tapered 3/4″ per foot of thread length so that the pipe and fittings will make up tightly to form a leakproof joint.

30 Chapter 6 — Joining, Installing, and Supporting Pipe Male (external) pipe threads are cut at the ends of pipe to engage properly with the fitting threads.

31 Chapter 6 — Joining, Installing, and Supporting Pipe Dig holes under underground drainage and waste pipe couplings, bells, or joints so pipe firmly rests on its barrel.

32 Chapter 6 — Joining, Installing, and Supporting Pipe Proper backfilling procedures ensure that underground pipe remains in position.

33 Chapter 6 — Joining, Installing, and Supporting Pipe Pipe hangers and supports are anchored to structural members, such as beams, studs, or joists, to ensure proper stability, support, and alignment of pipe.

34 Chapter 6 — Joining, Installing, and Supporting Pipe Brackets are used to support horizontal and vertical pipes, and are attached to wood and metal framing members and adjacent pipes.

35 Chapter 6 — Joining, Installing, and Supporting Pipe Riser clamps, pipe straps, and extension split pipe clamps maintain alignment of vertical pipe.

36 Chapter 6 — Joining, Installing, and Supporting Pipe A variety of hangers, clamps, and hooks are available to support horizontal pipe.

37 Chapter 6 — Joining, Installing, and Supporting Pipe Plastic pipe conveying hot water waste must be supported on continuous wood strips or angle iron for its entire length.

38 Chapter 6 — Joining, Installing, and Supporting Pipe Hangers must be placed adjacent to no-hub couplings.

39 Chapter 6 — Joining, Installing, and Supporting Pipe Sway bracing is used when cast iron soil pipe is suspended more than 18" from a ceiling using nonrigid hang­ers.

40 Chapter 6 — Joining, Installing, and Supporting Pipe Closet bends must be properly supported horizontally and vertically to prevent movement.

41 Chapter 6 — Joining, Installing, and Supporting Pipe Stacks must be properly supported at their bases.

42 Chapter 6 — Joining, Installing, and Supporting Pipe PEX tubing must be properly supported to prevent kinking and abrasion of the tubing.
