The supply pipes are used to convey or supply water from the main distribution line of the water supply system to the households i.e. to the service areas. In this regard, the supply pipes are also commonly referred to as service pipes. Such pipes can be made up of copper, polythene, galvanized iron, or lead.
GI Pipes. GI pipes are made from steel pipes, which are available in light, medium and heavy grades depending on the metal thickness. The galvanizing process deposits a thin coating of zinc which protects it from corrosion. GI pipes were previously the most traditional material used in water supply inside buildings.
There are five main types of plumbing pipe materials that are still in use today: copper, galvanized steel, polyvinyl chloride (PVC), acrylonitrile butadiene styrene (ABS), and cross-linked polyethylene (PEX). Chlorinated polyvinyl chloride (CPVC) is also used.
G.I. pipes were used in Olden days in house piping work but due to the lower cost and better properties, PVC pipes have replaced GI pipes almost completely. One big advantages for G.I. line is that they can be used for both hot and cold water lines.
There are two types of copper pipes are available namely HEAVY GAUGE and LIGHT GAUGE pipes. Heavy gauge pipes are used where pressure is very high, like as the leading pipe from distribution main, for large flows etc.
Concrete pipe is known as a rigid pipe that provides both structure and conduit when it arrives on site. Flexible pipe systems such as high density polyethylene (HDPE) and polyvinyl chloride (PVC) drainage systems, provide conduit only.
What are the differences between CPVC and PVC? The main difference between CPVC and PVC is the range of temperatures each is capable of withstanding. CPVC can handle temperatures up to 200° Fahrenheit, while PVC peaks at 140° Fahrenheit.
PVC is the most used plastic material for building and construction products such as pipes, cables, window profiles, flooring and roofing. PVC makes a major contribution to the quality, safety and cost-effectiveness of construction materials, as well as contributing to lower environmental impacts of completed projects.
It's the white plastic pipe commonly used for plumbing and drainage. PVC stands for polyvinyl chloride, and it's become a common replacement for metal piping. PVC's strength, durability, easy installation, and low cost have made it one of the most widely used plastics in the world.
CPVC (chlorinated poly (vinyl chloride) is a strong and rigid thermoplastic material that is used for hot and cold potable water applications in residential construction. Because of its makeup, CPVC is immune to damage from highly chlorinated domestic water and has a higher temperature tolerance than PVC.
