Pipes can be found in several sizes and types. They can be classified into three clusters in accordance with the material used in their manufacturing (Hart 2010). The first ones are metallic pipes such as steel pipes, CI pipes and GI pipes. The second ones are cementing pipes such as asbestos cement (AC) pipes, cement pipes and cement concrete pipes. The third group is the plastic pipes such as Polythene Pipes, low-density pipes and Un-plasticized PVC (UPVC) pipes (Hart 2010). Cast Iron (CI) pipes are used for water distribution. They are well structured to ease pressure and can resist external weight because of their width. The pipes are uninvolved in constructing, joining and arranging. This is a picture of a CI pipe. A 10-ft extent of 4-inch hubless CI pipe can be acquired for about $58 (Part 2010).
Steel pipes are widely used for water distribution. They are best appropriate as long-distance pipelines of high pressure and give the suitable performance when in service. Cementing pipes are familiar for their high corrosive resistance. Asbestos Cement (AC) pipes are light in heaviness and simple in lying out and carrying. They have a smooth internal surface and are not disturbed by rust or corrosion. Un-plasticized PVC (UPVC) pipes are extremely rigid pipes. Below is a picture of PVC pipes. A 10-ft extent of 4-inch PVC costs only $18.4 (Part 2010).
Hydronics refers to the application of water as a heat transfer means in heating and cooling systems (Siegenthaler 2011). Some of the earliest and most ordinary models are hot-water and steam radiators. Historically, in significant commercial structures such as campus facilities and high buildings, a hydronic system included both a heated and a chilled water loop. They offer both air conditioning and heating. Cooling and chiller towers can be applied separately or together as a way to offer water cooling, as boilers heat up water. A new innovation is the chiller boiler system. It gives a well-organized structure of HVAC for smaller commercial spaces and homes (Siegenthaler 2011). Recent systems put to use heated water instead of steam.
