It is the THINNEST ply of copper pipe and is ONLY used for heating purposes like baseboard heating!
The different grades of copper pipe available for plumbing applications are Type M, Type L, and Type K. These grades vary in thickness and are used for different levels of water pressure and temperature.
Copper tubing comes in several wall thicknesses K thickest L medium and M thin There is also ACR , DWV
Type L or Type K copper pipe is typically used for underground applications. These types of copper pipe have thicker walls than Type M copper pipe, making them more suitable for underground installation where they may be exposed to greater pressure or potential damage. Additionally, this thicker wall helps to prevent corrosion and allows for increased durability underground.
You can use type ( M ) in Tulsa Oklahoma, but i always use type ( L ) easer to put together
I have a new copper pipe not been used who do I sell it to? Or who would buy it off me as 'm moving house and want to get rid of it.
m
L copper is thicker
The most common pressure applications are K, L and M, from thickest wall to thinnest. However, there are other types that are not used on water lines- DWV ( drainage waste and vent ), H ( hydronic heating) and medical gases.
Both. M used for hot water heat. L used for domestic hot and cold water.
K copper.
Most plumbers today no longer use coper "pipe" or TP copper as the cost is to high=What plumbers and HVAC and other trades use is Copper tubing types K, L, M, DWV, ACR=
Type K ( extra heavy) L medium (color blue) M light tubing (Green) Then there is DWV (Yellow) and TP and ACR
