The size of wall thickness effects copper tube's mechanical strength, working pressure. Type L copper tubes are suitable for pipelines requires strength & protection.

Normally tubes of this type are applied for underground pipeline, hotwater pipline of commercial plumbing projects.

Winland's different types of copper tubes are manufacturered with pure copper (C12200, 99.9% cu plus 0.015~0.040% p), outside diameter of the tubes are the same, it means they can use with same size copper fittings for soldering and connection.

Dimensions listed below are for rigid tubes, aslo known as hard temper (H58) copper tube, supply in straight length form (5.8 meters or as request). If you need customized dimensions or annealed temper products, please feel free to email us.
