Looking For Schedule 40 & Schedule 80 Pipes In UAE


Introduction to Schedule pipes


In the field of pipe systems, the term "Schedule" refers to how heavy or light duty a piping component is. The thickness of the pipe, or more particularly the wall thickness of the pipe, is detailed in the Pipe Schedule with respect to various internal pipe bore diameters. For a given nominal diameter designation, the pipe diameter remains constant under this approach. A 2" pipe, for example, will have the same outside diameter in Sch 20, Sch 40, Sch 80, and Sch 120 systems, but its thickness will increase in the same order. Because the system is common in iron pipes, it is also known as the Iron pipe size (IPS) system. Plastic pipes based on the same concept have also been developed to ensure parity.



Schedule 40 PVC Pipe has a thinner wall thickness and can handle pressures up to 60 degrees Celsius. These PVC pipes are frequently utilized in residential and commercial buildings, as well as individual homes, for cold water supply. The piping technology is also employed for major residential projects' water supply mains.

Schedule 80 PVC Pipe (SCH 80)

Schedule 80 PVC Pipe has a thicker wall thickness and can handle high pressure at temperatures up to 60 degrees Celsius. These PVC Pipes are utilized for cold water supply in high-rise residential and commercial buildings, as well as other high-pressure water applications. As a result, these pipes are used in a variety of industrial applications.



The design of these two pipes is the first thing that stands out. When compared to schedule 40 PVC pipe, schedule 80 PVC pipe has a thicker wall. Pipes with thicker walls are more structurally and chemically durable, as well as more resistant to stress and pressure. Because schedule 80 pipes are thicker and stronger, they can withstand larger pressures.



Schedule 40 pipes are the most popular type of drainage pipe used in both residential and commercial buildings, and they are readily available at any hardware shop. Schedule 40 pipes are ideal for cold-water systems because they are sturdy, stiff, and can withstand high pressures.

Schedule 80 pipes, on the other hand, are best suited for applications requiring higher pressurisation. The pressure is measured in PSI (pounds per square inch). A 4′′ schedule 80 PVC pipe has a 320 PSI rating, whereas a 4′′ schedule 40 PVC pipe has a 220 PSI rating. Schedule 80 pipes are most commonly utilized in heavy-duty commercial and industrial applications for these reasons.


When compared to schedule 40 rated plumbing supplies, schedule 80 rated plumbing supplies have a greater buying cost. This is due to the extra material utilized for a thicker sidewall and the colorant added. Because of the thicker wall, schedule 80 PVC pipes and fittings are unquestionably heavier than schedule 40 PVC pipes and fittings.
