Installing Procedures for PPR Pipes and Fittings

Among the various types of thermoplastics which have come to acquire widespread use in piping applications, the versatile polypropylene random copolymer or PPR pipe is a new innovation. PPR pipes and fittings are made from copolymers of propylene with at least one comonomer. PPR pipes and fittings have a wide range of properties which make them well suited for drinking water supply, water drainage, as well as heating and cooling systems. In order to connect PPR pipes, the appropriate joining methods must be used in order to maintain the structural integrity of the system and ensure higher efficiency. Let us take a look at the correct method to install PPR pipes:

1. PPR pipes and fittings can be joined using welding to make secure connections. The welding is used to secure the fittings to the pipes, creating a cohesive connection that can withstand the toughest pressure and service conditions for lasting efficiency.

2. The installation of PPR pipes can be concealed or external and the conditions to be met for these differ on the basis of the pipeline. In case of concealed installations, allowances must be made for the expansion of the system. For external installations, linear expansion must be specifically considered for optimal functionality.

3. Since PPR pipes are lightweight and durable, joining them at the site of installation can often pose a problem. To save time and costs, hence, a workbench is made use of for the welding.

4. The pipes to be joined must have clean cuts in order to facilitate a smooth connection.
 
5. All PPR pipes and fittings which are to be used for the installation must be chosen with due consideration for the design requirements. The grades of the pipes for hot and cold applications must be duly checked for correct installations.

6. Connection of PPR pipe fittings with PPR pipes is generally made with heat welding method. During this process, only the appropriate amount of pressure must be applied to the fittings and the pipes to prevent cracks and secure the connection. PPR pipes can also be connected using the hot-melt socket connection method which imparts higher durability to the system.

How to Choose A Pipe Best Suited for Sewer Pipelines?

Image
When it comes to the installation of plumbing pipelines, one of the functions which is to be catered for is the sewage management through an appropriate sewer pipeline. The sewer lines carry the wastewater out of the buildings and hence serve an important function in maintaining hygiene and sanitation for the convenience of the people in and around the building. This makes it imperative to install sewer pipes which can withstand the service conditions. When selecting the sewer pipe materials, here are some considerations to keep in mind:

Useful Properties of PPR Pipes And Fittings

 Among the many modern plastic materials being used in pipe networks for various applications is polypropylene random copolymer plastic or PPR as it is known commonly. Nowadays, PPR Pipes and Fittings are used across domestic and industrial applications. PPR piping system is also used central heating and radiator systems in residential and commercial buildings. The high demand for PPR pipe fittings and pipes stems from the many useful properties they have. Let us take a look at the various properties of PPR pipes and fittings: 1.        PPR pipes and fittings have a longer service and can remain operational for more than 50 years at a time without being damaged or cracked. They are durable and have high strength, resisting action by natural conditions such as roots of trees and plants as well. 2.        PPR pipes and fittings have low thermal conductivity which means that they do not transfer heat or cold to the ext...

Properties Of Ppr Pipes And Fittings

Image
 Plastic pipes and fittings have now become the material of choice for piping applications in different environments. Among the different thermoplastic pipes which are nowadays available for piping applications, polypropylene randomized copolymer, or what is understood as PPR in common parlance are one of the most common materials used for different environments, mostly in commercial and industrial setups. There are several useful properties of PPR pipes and fittings that make them a suitable choice for different applications. Let us try and understand them in brief: 1.        One of the best properties of PPR pipes and fittings is that they are long lasting and durable. Their service life extends to over 50 years without damage even under the harshest service conditions even outdoors. They are also suitable for both hot and cold water applications, able to withstand the supply of water at high temperatures without losing their structural integrity....
