SCH 80 ERW Pipe Dimensions Chart: Wall Thickness & Weight

What is SCH 80 ERW Pipe?

SCH 80 (Schedule 80) represents the wall thickness of the pipe. It refers to XS (Extra Strong) thickened pipes with a pressure wall thickness. Usage scenarios generally involve high temperature, high pressure, and highly corrosive conditions.

ERW (Electric Resistance Welded) pipe means the pipe is manufactured by rolling steel coil and welding it longitudinally across its length. Combining them, SCH 80 ERW pipe offers a thick, high-pressure-resistant wall with a cost-effective manufacturing process.

SCH 40 vs SCH 80 ERW Pipe

The main difference between SCH 40 and SCH 80 ERW steel pipes is the wall thickness. SCH 40 pipe has a thinner wall thickness and is often used in low-pressure applications such as residential plumbing or irrigation systems. SCH 80 ERW pipe has thicker walls and is used in high-pressure applications such as industrial processes, hydraulic systems, and underground piping.

Because SCH 80 pipe has thicker walls, it requires more material and more manufacturing time, which increases costs. When selecting pipe for a specific application, it is important to consider the pressure requirements and the cost-effectiveness of selecting thicker, more expensive pipe.

Features and Applications of SCH 80 ERW Pipe

Features:

● High-temperature heaters and hydraulic systems.
● Chemical equipment and specialized piping systems.

FAQs

Q1: What is the wall thickness of SCH 80 pipe?
A: Wall thickness varies by pipe size. For example, a 2" SCH 80 pipe has a wall thickness of 5.54 mm (0.218"), while a 6" SCH 80 pipe has a wall thickness of 10.97 mm (0.432").

Q2: Is SCH 80 ERW pipe suitable for high pressure?
A: Yes, SCH 80 ERW pipe has a thicker wall than SCH 40, making it suitable for high-pressure applications, hydraulic systems, and industrial processes.

Q3: What is the difference between XS and SCH 80?
A: For pipes up to 8 inches, XS (Extra Strong) and SCH 80 are identical. For sizes 10 inches and above, SCH 80 wall thickness is greater than XS.

Q4: Can SCH 80 ERW pipe be welded?
A: Yes, ERW pipe is highly weldable. Threaded and socketed connections are also common for SCH 80 pipe.
