HALF HARD COPPER TUBING (5,5m straight lengths)

460/1 LIGHT – HALF HARD (5,5m straight lengths)
Identification: Orange end-caps on bundle.

15 (HD)0.7013.60.28051.3Recommended for above ground use only. Should only be bent with a bending tool having inner and outer formers. Spring bending is not recommended. Tubing is ideally suited for use with compression and/or soldered capillary fittings. Care should be taken when soldering due to the increased wall thickness.

The half hard, thin-walled tube is also meant for above ground use. As opposed to the hard drawn, thin-walled tube manufactured by DOWEDO Copper Tubing, this tube can be bent using a bending tool with inner and outer formers. It is also ideally suited for use with capillary or compression fittings.

We don’t recommend brazing of SANS 460 Class 1 from 15mm to 28mm O.D. using capillary fittings. Nor do we recommend the use of oxy-acetylene. The SANS 460 Class 1 is ideally suited for the drawing of T-joints.

The half hard tube features superior bending qualities. Under normal conditions, it may be used for underground applications. Normal conditions in this context refer to non-aggressive soils.

The 28mm tube in this class is perfectly suited for brazing and for drawing of T-joints. It is the only class that can be bent using internal bending springs, however, we urge that you take care when installing the tube underground as it should be protected against external corrosive materials.
