Threaded pipes, also known as screwed pipes, are widely used in plumbing, industrial piping, and chemical transport systems due to their ease of installation and reliable connections. Understanding the materials, sizes, and standards of threaded pipes is essential for selecting the right product for your project.
Materials
Threaded pipes are manufactured from a variety of materials to suit different applications:
-
Carbon Steel Threaded Pipes: Ideal for high-pressure pipelines in industrial and construction projects, carbon steel offers strength and durability. Learn more about carbon steel pipes.
-
Stainless Steel Threaded Pipes: Resistant to corrosion, stainless steel threaded pipes are perfect for chemical, food, and water applications. Check our stainless steel pipe selection.
-
Galvanized Steel Threaded Pipes: With a protective zinc coating, galvanized pipes are suitable for water supply systems and outdoor installations. Explore galvanized pipes.
Sizes
Threaded pipes come in a wide range of nominal diameters and wall thicknesses, allowing engineers and contractors to choose the best fit for low-pressure and high-pressure systems. Common sizes include 1/2 inch to 12 inch nominal diameters, but custom sizes are also available for specialized industrial applications. Proper sizing ensures optimal flow rates and system efficiency.
Standards
Threaded pipes are manufactured according to international standards to ensure compatibility, safety, and reliability:
-
ANSI B1.20.1 / ASME B1.20.1 – American standard for pipe threads.
-
BS EN 10255 – British standard for welded and seamless steel pipes.
-
JIS B2312 / JIS B2220 – Japanese standard for threaded steel pipes.
Using pipes compliant with these standards guarantees consistent performance in residential, commercial, and industrial piping systems. For more information, see our resources on industrial piping standards.
Threaded pipes offer ease of assembly, reliable leak-proof connections, and versatility. They are widely applied in water supply networks, gas distribution, chemical plants, and mechanical systems. By choosing the right material, size, and standard, you can ensure a long-lasting and efficient piping solution.
