We offer high-quality Schedule 80 Carbon Steel Pipes that are built to perform under high pressure, high temperature, and tough industrial environments. Whether you need Schedule 80 Seamless Pipe, SCH 80 Carbon Steel ERW Pipe, or Schedule 80 CS Welded Pipe, we have the right product to meet your requirements.
What is Schedule 80 Carbon Steel Pipe?
A Schedule 80 Carbon Steel Pipe (also called SCH 80 Pipe) is a type of steel pipe with thicker walls compared to standard Schedule 40 pipes. The “Schedule” refers to the wall thickness of the pipe, and Schedule 80 indicates a higher pressure rating and strength. These pipes are commonly used in:
- Oil & Gas
- Petrochemical Plants
- Power Generation
- Construction
- Marine & Offshore Applications
Because of their robust nature, they are also preferred over Schedule 80 PVC Pipes in high-temperature or pressure environments.
Key Features of Schedule 80 Carbon Steel Pipe
- High strength for demanding applications
- Excellent pressure resistance
- Suitable for above-ground and underground use
- Available in seamless and welded types
- Corrosion-resistant (especially when galvanized)
- Compatible with ANSI and ASME standards
Types of Schedule 80 Pipes We Offer
At ASC LLP, we supply a wide range of Schedule 80 Steel Pipes:
- Schedule 80 Seamless Pipe: These are manufactured without a welded seam and are known for their uniform strength. Commonly used where high pressure is involved.
- SCH 80 Carbon Steel ERW Pipe: ERW (Electric Resistance Welded) pipes are manufactured by welding the steel edges together. These pipes are cost-effective and ideal for structural and low-pressure applications.
- Schedule 80 CS Welded Pipe: CS stands for Carbon Steel. Welded Schedule 80 pipes are produced by rolling a steel coil into a cylindrical shape and welding the seam. Suitable for general industrial and construction use.
- Galvanized Pipe Schedule 80: Galvanized SCH 80 pipes have a zinc coating that protects them from rust and corrosion. These are used in plumbing, outdoor installations, and even marine environments.
- Schedule 80 Mild Steel Pipes: Made from low-carbon steel, these pipes are easy to weld and shape. Great for applications where strength and flexibility are required together.
