Schedule 80 Pipes

Schedule 80 Pipes (1/2", 4" & 8")
Schedule 80 pipes are used in Saudi industries that require strong piping systems. These have thicker walls and are built to handle high-pressure jobs. They are much more reliable than standard Schedule 40 pipes and are used to safely move dangerous and heavy materials.
As a trusted industrial piping solutions provider of schedule 80 pipes in Saudi Arabia, National Oil Groups provides high-quality piping solutions for your projects. Our pipes are made from special materials like PVC, CPVC, and carbon steel, which deliver great performance in harsh operating conditions.
What Are Schedule 80 Pipes?
Schedule 80 pipes are heavy-duty plastic pipes with thick walls used in industrial piping systems in Saudi Arabia. They are made from special materials like PVC or CPVC and are used to move liquids under high pressure. Their walls are much thicker than household pipes, so they can easily handle higher water pressure and temperatures without leaking or bending. Their color is dark gray, and they are mainly used in factories, chemical plants, and other industrial applications.
- Thick-Wall Pipes: Compared to Schedule 40 pipes, they have much thicker walls. This means they are thicker and contain more material.
- Suitable for High-Pressure Systems: As their walls are thicker, they can withstand higher internal pressure without bursting.
- Better Strength than Schedule 40: These pipes are super tough and don’t break or bend easily. These show super resistance against physical impacts, chemical damage, and high heat.

As a leading Schedule 80 pipes supplier in Saudi Arabia, we provide piping solutions that you actually need. Whether you handle high-pressure jobs or transport harsh chemicals, we deliver high-quality SCH 80 pipes for your projects on time.
SCH 80 Pipe Size | Description | Best Use | Key Feature |
1/2″ Schedule 80 Pipe | This is a half-inch wide pipe, and its small size makes it great for tight, high-pressure water or plumbing lines. | Tight commercial or residential spaces, high-pressure, and compact fluid transport. | Takes up little space, is very tough, and doesn’t break under high pressure. |
4” Schedule 80 Pipe | This is a 4-inch-wide pipe and is generally used to move high-pressure fluids in factories. | Used to safely move water, hot steam, and chemicals in factories. | Have high-flow capacity and stay incredibly strong under tough conditions. |

Schedule 80 Pipes vs Schedule 40 Pipes: Key Differences
Businesses operating in diverse industries across Saudi Arabia heavily use SCH 40 and SCH 80 pipes. SCH 80 pipes are mainly used for heavy-duty industrial, high-pressure, and corrosive applications. However, the other type of pipes is best for low-pressure systems.
Feature | Schedule 40 | Schedule 80 |
Wall Thickness | Thinner walls | Thicker walls (around 25 to 40% thicker than SCH 40 pipes) |
Pressure Capacity | Lower around 1,000 PSI | Higher (handles extreme stress, high pressure, and industrial loads) |
Internal Diameter (ID) | Larger (allows higher flow rates with less friction) | Smaller (harder for the liquid to flow, stronger pumps are required for the same volume) |
Weight | Lighter | Heavier (due to more material) |
Flow Rate | Higher because the inner passage is large | Lower because the inside of the pipe is small |
Cost | Cost-effective | More expensive |
Typical Use Cases | Residential plumbing, HVAC, irrigation, light commercial, and drainage | Oil and gas refineries, petrochemical plants, and heavy industrial |
