5 Major Types of Sewer Pipes and Joint Materials

Plumbermascot AC Pipe

Upon installation of sewer pipes and joints, deciding upon the kind of piping and joint materials to be utilised is a crucial task which requires intensive decision making. It is always salient to choose the piping and joint material that has a high resistance towards many factors that causes early sewer pipe and joint deterioration. Resistance to the stress caused by surface loads, root intrusion, chemical reaction, kind of water they convey and the ability to resist activities that cause leakage and cracks. Cautious decision making should be taken to ensure the wealth of your sewer system so they can be serviceable for many years after installation.

Here are the various piping and joint materials you can choose from for your sewer system.

  1. Asbestos Cement Pipe (AC)

Asbestos cement pipe is commonly used by many households as it has a high resistance to deterioration and corrosion caused by various types of conveyed wastewater. Its only weakness is the corrosion caused by hydrogen sulphide which forms or produces sulphuric acid upon combination with moisture. This should only be used on wastewater system where the release of hydrogen sulphide is not a frequent occurrence. This is composed of a rubber gasket and a sleeve and is mostly used in many wastewater systems, drainages and air ducts.

  1. Cast and Ductile Iron (CI and DI)

This is suitable for underground sewer paths located below roads and earth surfaces where heavy equipment and heavy loads tend to pass. This is because the cast and ductile iron pipes are durable and strong enough to resist the pressure caused by heavy loads. They are usually used for bridge crossing and areas with heavy traffic loads. They might have costly upfront cost but they can assure the wealth and security of your sewer systems.

  1. Reinforced and Non-Reinforced Concrete

Similar to that of the ductile and cast iron pipe, reinforced and non-reinforced concrete pipes are as well very rigid and tough to resist heavy surface loads. Proper handling and careful installation are required by concrete pipes though, because when they are not well-laid and installed, they may create leaks and early signs of failure. These pipes are composed of a spigot and a rubber gasket bell used for proper and effective pipe connections preventing any water and wastewater escapade. They are commonly lined with coal tar and epoxy lining so they won’t be subjected to chemical reactions and activities that may cause corrosion.

  1. Vitrified Clay Pipe

Vitrified clay pipe is well-known because of its ability to resist any type of corrosion caused by any chemical content in wastewater. They are mainly composed of mortar-sealed bell and spigots for an easy yet effective pipe connection. Their only weakness is its lesser resistance against the destruction caused by root intrusion. Most of the times vitrified clay pipe experiences failures and issues due to the problems and destructions caused by tree root intrusion.

  1. Reinforced Fibreglass

Reinforced fibreglass is utilised in many wastewater systems because of its ability to resist corrosion and its flexibility. It has the capability to bend without producing cracks and leakage even when not properly handled. It is assured that no matter what kind of chemical solutions are found in the conveyed wastewater, reinforced fibreglass is free from any form of corrosive activities.
