Hard drawn, thin-walled tubes are recommended for above ground use because of copper ability to withstand extreme temperatures. The thin wall makes it unsuitable for underground usage due to a lack of flexibility. We don’t recommend bending the tube, however, a change in direction using SANS 460 Class 0 may be made using capillary fittings.

We recommend that when using compression fittings, you never use brass rings as they are extremely hard and can cut too deeply into the copper wall, causing it to snap off at the joint.

Local annealing in order to produce a bend, offset or crossover is not recommended. Nor is brazing of SANS 460 Class 0 from 15mm to 28mm O.D. using capillary fittings and the use of oxy-acetylene.

CTA 460/1 LIGHT - HALF HARD (5,5m straight lengths)

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 Copper Tubing Africa, 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.

15 (HD)1.2012.60.46488.0Designed for use underground. Subject to special conditions. Can be bent using a bending tool and should be lagged. Spring bending is not recommended. Tube and DZR compression fittings ideally suited for underground use. When used above ground, special care should be taken.

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.
