A pipe is a cylindrical, hollow tube typically used to transport fluids, gases, and sometimes solids from one location to another. Pipes are fundamental components in various industries, including construction, oil and gas, water supply, chemical processing, and more. They are designed to withstand pressure and temperature variations and are made from a variety of materials to suit different operational environments.
Pipes are manufactured in various sizes, grades, and lengths, with specific standards for wall thickness, pressure rating, and materials. The selection of pipe type is based on the fluid or gas being transported, temperature, pressure, and environmental conditions such as corrosion or abrasion.
