1 1/2 Copper Pipe
1 1/2 copper pipe is a commonly used pipe size in plumbing, HVAC, and industrial piping systems where higher flow capacity is required. Known for its excellent corrosion resistance, durability, and thermal conductivity, this pipe size is widely used in commercial buildings, industrial plants, and large-scale residential systems.
Its ability to handle higher volumes of fluid while maintaining efficient flow makes 1 1/2 copper pipe an ideal choice for main supply lines, distribution systems, and process piping applications.
What is 1 1/2 Copper Pipe?
1 1/2 copper pipe refers to a copper pipe with a nominal diameter of 1.5 inches. It is part of the standard copper pipe sizing system and is available in various wall thickness types such as Type K, Type L, and Type M.
This size is typically used in systems where medium to high flow rates are required.
