PowerPoint 4 Fixings and components used in common plumbing processes  LESSON INTENT Learners will be able to identify the following and where they are used: Fixings and components used in common plumbing processes Fixings Clips Clipping distances Surfaces Buried cable Buried pipework Selecting fixing methods for different surfaces Measuring out clipping distances Identify different surfaces Performance of fixings to different surfaces  Screw styles There are many types of screws available for different applications: countersunk cross-head Pozi drive raised countersunk round head mirror coach chipboard. Countersunk screws are used for general-purpose work. The head sinks flush or a little below the wood surface, ideal for floorboards. Plumbers will use brass countersunk screws to secure items where there is a corrosive atmosphere. Screw styles Common head types  Brass Stainless steel Steel Chrome Zinc Sheradised  Fixing materials Brass: high moisture areas – corrosion resistant. In/outside use. Expensive, long lifespan. Concealed bathroom use. Stainless steel: high moisture areas due to corrosion resistance. Inside or outside use. Expensive, long lifespan. Exposed bathroom (cleaning) and commercial applications. Steel: general purpose inside use. Dry conditions. Cheap, good lifespan, general purpose concealed (floorboards). Chrome: decorative finish. Expensive, long lifespan. exposed bathroom use (cleaning). Zinc: general purpose inside/outside, corrosion resistant. Cheap, good lifespan. Sheradised: limited outside use only. Mirror screws are used for fixing mirrors and bathroom fittings, like bath panels, in place. The chromed/coloured cap threads into the screw head to hide the screw.  Plasterboard fixings Expanding plastic wall plug Expanding metal cavity fixing  Plasterboard fixings Spring toggle fixing Self-cutting fixing (self-tapping screw for metal)  Masonry fixings Rawl bolt Self-tapping wall bolt Fischer bolt basin set Standard plastic wall plugs  Size matches of screws, drills, plugs Screw size Drill size (mm) Plug colour (gauge) 6-8 5 Yellow 8-10 6 Red 10-14 7-8 Brown 14-18 10 Blue Why is it important to clip Pipe?  Pipe clips Nail clip Single and double push- in clip Single and double clip lock Interlocking clips are used where several runs of pipe are clipped together. This ensures uniformity in the pipework run, which is often hard to accomplish with single clips. The clips slide/lock together, giving equal spacing to the pipework run. The clips allow for a stand-off from the wall, so that insulation can be fitted, if required.  Pipe clips Single copper Single cast brass saddle clip schoolboard clip Single stamped Single munsen brass schoolboard ring clip clip (adjustable) Munsen rings can be supplied with a rubber inset. This prevents noise and vibration problems in the installation.  PIPE CLIPPING DISTANCES Copper Pipe size Horizontal Vertical 15mm 1.2m 1.8m 22mm 1.8m 2.4m 28mm 1.8m 2.4m LCS Pipe size Horizontal Vertical ½″ 1.8m 2.4m ¾″ 2.4m 3.0m 1″ 2.4m 3.0m Plastic Pipe size Horizontal Vertical Pressure 15mm 22mm 0.3m 0.5m 0.5m 0.8m Pipe 28mm 0.8m 1.0m Clipping distances for soil and waste Soil Waste Horizontal 1m 0.75m Vertical 2m 1.50m  Clip Copper LCS Plastic PP Brass YES munsen ring Cast iron YES munsen ring Cast brass YES school board Strip brass YES school board Cast iron YES school board Interlocking YES YES Single YES YES Double YES YES Nail on YES YES Copper YES saddle Reasons for clipping distances Pipe support Limit pipe sagging Plastic pipe sags when heated Smaller diameters are weaker Vertical force is different to horizontal force  Surfaces: building fabric Studwork Brickwork Hidden after Usually outside first fix by finish, uneven plasterboard and hard Plasterboard Blockwork Soft fabric finish Hidden internal fabric requiring painting (first fix). Plastered or rendered. Wood Tiling Commonly Hard decorative floorboards or finish: bathrooms, lining finish. WCs, kitchens and floors  CHECK YOUR KNOWLEDGE WITH THESE QUESTIONS. 1. Name 5 different screw styles. 2. Name 5 different screw head styles. 3. What is the purpose of a mirror screw? 4. Name some plasterboard fixings 5. name some masonry fixings 6. Why is it important to have the correct clip scaping? 7. name some different types of clips. 8. What is the clipping distance for 15mm vertical copper piping.  TRAFFIC LIGHT IT: WHERE IS YOUR LEARNING AT?
