8 Types of Plumbing Pipes

The modern day’s plumbing markets are flooded with the various types of plumbing pipes. These pipes are made up of different base materials causing each of them to have their own capability and limitations. Some of them are intended to carry drinking water for domestic use while some aren’t suitable for the said work. This is because some of the pipes corrode easily making them unsuitable for drinking water carriage, especially of acidic water conditions. Forcing a corrosive pipe to carry drinking water might endanger your health and your family’s. In order to avoid these health risks, make sure to know the types of plumbing pipes so you can choose the best pipe for a specific role. This article is specifically made to present to you the eight types of plumbing pipes.

Metal Pipes

  1. Copper pipes

Copper pipes are the most widely used metal pipes nowadays. This is because, though they are more expensive, they have the capability to withstand corrosion and can stand the stresses caused by varied temperature.  Copper pipes usually have three primary categories according to its wall thickness, M as the copper pipe with the thinnest walls, L as the median wall thickness and K as the thickest among the three.

  1. Galvanized pipes

Galvanized pipes are considered safe for water transportation and are suitable to be used as drinking water pipes. This is because it can resist corrosion though it is not found in most households nowadays. This is a steel pipe with a zinc coating that prevents the pipe from being eaten by corrosion or the acidic component of the water it may carry. These pipes may still exist in many older homes but not on modern homes.

  1. Stainless steel pipes or CCST

Stainless steel pipes are more expensive compared to copper pipes thus, do not exist in most household’s plumbing systems nowadays. This metal pipe has a high corrosion resistance and is usually used by most marine equipment such as ships and submarines to avoid their pipes from being eaten by corrosion due to the sea water’s salinity.

  1. Cast Iron Pipes

Cast iron pipes are commonly used for water transportation and drainages. Historically, this pipe is used for water transportation, gas and sewage conveyance. This pipe is not commonly utilised in most households because of the inconvenience during replacements and installations. This pipe is very heavy making it difficult to replace and are usually used without coating though coating can add up to the resistance against corrosion.

Plastic Pipes

  1. PVC (Polyvinyl Chloride)

PVC pipe is the world’s most widely used plastic pipe for a home’s plumbing system. They are commonly grey or white coloured designated for high water pressure. They come in various sizes and diameters yet all of them can be either solid-walled or cellular-cored. Cellular core PVC pipe has an extrusion of at least three layers on its pipe walls. In the modern days, this has been commonly used as a replacement for most metal pipes.

  1. CPVC (Chlorinated Polyvinyl Chloride)

This pipe is a thermoplastic produced by polyvinyl chloride resin chlorination. This is as well highly durable and can resist the destruction caused by corrosion. Most industries prefer using this to carry oil, water and industrial liquids.

  1. PEX (Cross-linked Polyethylene)

This pipe is commonly used for a household’s interior plumbing system. This is a heat resistant pipe and is best used to carry hot and cold drinking water for most families. Because of that, they have the capability to resist leaks caused by varied temperature and can prevent crack growth as well.

  1. PB (Polybutylene)

Plastic polybutylene is a flexible water pipe that usually comes in a coil. They are commonly used to replace copper pipes in the past generations. Yet in the modern days, it is no longer used that much because it has been proven to be vulnerable to cracks and leaks.
