As an example, a 5 inch pipe with an outer diameter of 114.3 mm will have a wall thickness of 11.13 mm for Schedule 120 pipes. Similarly, a 14 inch pipe with an outer diameter of 355.6 mm will have a wall thickness of 150.49 mm. Schedule 120 pipes are suitable for liquid and gas transmission applications but not recommended for corrosive services. They are known for their toughness and are used in the construction and automotive industry. We subject our Schedule 120 steel pipes for sale to various tests to confirm their quality and properties.
The schedule 120 steel pipes dimensions chart is helpful in determining the appropriate size and weight for a specific application. At Steel Tubes India, we offer high-quality Schedule 120 pipes with various wall thicknesses, and we provide them at a competitive price compared to other suppliers in the market.

Schedule 120 Pipe Applications
Schedule 120 pipes are commonly used in various industrial applications that require high pressure containment capacity. Some of the typical applications include oil and gas transmission pipelines, steam lines, and high-pressure water lines. They are also used in the chemical processing industry, power generation plants, and pulp and paper mills. Due to their robustness and toughness, they are suitable for applications in the construction and automotive industry as well. However, Schedule 120 pipes are not recommended for corrosive services.
