Copper pipes comes in four types – K, L, M and DWV. these identifications are based on their thickness. for copper L type it needs to be color-coded in blue. before choosing any types of pipe its
better to understand their wall thickness & pressure rating. talking about wall thickness 3/4 inch is 0.045(inch) while 1/2 inch is of 0.040(inch). comparing with price the type M is more costlier than
Type L since type L is more thicker than than type M. Type L copper pipe are most commonly used to supply water in building. Aesteiron steels LLP is one the leading manufacturer of type L pipe. They export these pipes worldwide including high demanding countries like Saudi Arabia, Qatar, Malaysia, and Indonesia. based on the record, Aesteiron is listed as one of the top 10 exporter in India of Type L Copper Tubing For Refrigeration.

Can Type L Copper Be Used In Refrigeration?
Yes, type l copper pipe is most suitable to carry propane, CO2, isobutane for refrigeration.
Types L Tubing manufactured in drawn temper from ¼” to 12″ and annealed temper (soft) coil tubing
The ASTM standard for type L water tube is B 88. manufactured from copper alloy C12200. These tubes
comes in 3 types of thickness namely K, L & M. M being the thickest, L being intermediate. these tubes
are manufactured from size ¼” to 12″ with heat treatment annealed temper.
