Steel rigid pipes are a type of pipe made of steel that are used for conveying fluids and gases in various applications such as in industrial, commercial, and residential buildings. They are typically made of carbon steel and come in various diameters and lengths. Steel rigid pipes are known for their strength and durability, making them suitable for use in applications where high pressure and harsh conditions are present. They are often used in underground water and gas lines, fire protection systems, and HVAC (heating, ventilation, and air conditioning) systems. Steel rigid pipes can be joined together using various techniques such as threading, welding, and grooving. Proper installation and maintenance of steel rigid pipes are essential for the safe and efficient operation of fluid and gas conveying systems.
