Carbon Seamless Steel Pipes
Schedule 40 steel pipe is the most commonly used pipe diameter. It can be galvanized (though not required) and is commonly used for water and gas lines. It may also be used where decorative or supportive materials are required.
Due to its versatility and strength, it makes for high-quality pipe.
SCH 40 steel pipe is widely used in several key industries due to its moderate wall thickness, good pressure bearing capacity, excellent weldability, and cost-effectiveness. It is widely used in medium- and low-pressure oil and gas transportation systems and is a vital component in oil and gas field surface engineering and refining facilities.
In chemical plants, SCH 40 steel pipe is used to transport a variety of chemical media, particularly in non-corrosive, medium-temperature, and medium-pressure environments.
In thermal power plants and industrial boiler systems, SCH 40 carbon steel seamless pipe is often used for non-high-temperature and high-pressure main steam piping. SCH 40 steel pipe is not only used for fluid transportation but is also widely used as structural support due to its high strength and circular cross-section.
In the HVAC systems of large commercial and industrial buildings, SCH 40 steel pipe is used to transport hot water, chilled water, and steam.
