Galvanized pipes come in many specifications and thicknesses. Here are some common specifications and thicknesses:
Commonly used specifications: The specifications of galvanized pipes are usually expressed in diameter, such as DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80, DN100, DN125, DN150, etc. The outer diameters of the pipes corresponding to these specifications are 21.3mm, 26.8mm, 33.5mm, 42.3mm, 48mm, 60mm, 75.5mm, 88.5mm, 114mm, 140mm, and 165mm respectively.
Commonly used thicknesses: The thickness specifications of galvanized pipes usually include 0.8mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, etc., in millimeters. Galvanized pipes of different thicknesses are suitable for different occasions. For example, 0.8mm galvanized pipes are often used for water supply and gas pipes in residential areas, 1.0mm galvanized pipes are often used for indoor water supply and drainage, and 1.5mm galvanized pipes are often used for cold storage. For hot water pipes, 2.0mm galvanized pipes are often used in ventilation ducts in industrial buildings. When used in humid environments, it is recommended to use galvanized pipes with a thickness of 2.5mm or more.
Dimensions: The length of galvanized pipe is usually ordinary length, and the length tolerance is -0mm to +50mm.
