Frequently Asked Questions
What are pipes and tubes?
Pipes and tubes are hollow cylindrical products used to transport fluids, gases, or solids and for structural or mechanical applications. They are available in various materials, sizes, and grades.
What is the difference between a pipe and a tube?
Pipes are mainly used to carry fluids and are measured by nominal pipe size (NPS) and schedule. Tubes are used for structural and precision applications and are measured by their outside diameter (OD) and wall thickness.
What are pipes and tubes used for?
Pipes and tubes are used in industries such as oil and gas, chemical processing, power generation, construction, marine, food processing, and pharmaceuticals for fluid transportation and structural support.
How are pipes and tubes measured?
Pipes are measured by nominal pipe size (NPS) and wall thickness (schedule), while tubes are measured by their outside diameter (OD), inside diameter (ID), and wall thickness.
What is the difference between seamless and welded pipes and tubes?
Seamless pipes and tubes are made from a solid billet without a welded seam, offering higher strength and pressure resistance. Welded pipes and tubes are formed by rolling and welding metal sheets, making them more economical and suitable for many industrial applications.
Which is stronger, seamless or welded pipes?
Seamless pipes are generally stronger because they do not have a welded joint, making them better suited for high-pressure, high-temperature, and critical applications.
