NOT recommended

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.

15 (HD) 0.70 13.6 0.280 51.3 Recommended 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.

The 28mm tube in this category is utterly suited to brazing and for drawing of T-joints. it’s the sole category that may be bent mistreatment internal bending springs, however, we have a tendency to urge that you simply lookout once putting in the tube underground because it ought to be protected against external corrosive materials.The half exhausting tube options superior bending qualities. under traditional conditions, it’s going to be used for underground applications. traditional conditions during this context talk over with non-aggressive soils.

Specifications for Copper Tube

SANS 460 category 0:

A hard drawn thin-walled tube to be used while not bending, and counseling for higher than ground use solely. the exhausting drawn tube isn’t counseled for underground use because of its skinny wall and lack of flexibility. Any amendment of direction mistreatment SANS 460 category zero ought to be created mistreatment capillary fittings.

Local tempering so as to provide a bend, offset or crossover isn’t counseled. Oxyacetylene brazing of SANS 460 category zero mistreatment capillary fittings isn’t counseled.

SANS 460 category 1:

A halfexhausting thin-walled tube for higher than ground use solely. This tube is bent employing a bending tool with inner and outer formers. String bending isn’t suggested because of the spring being too loose within the tube and therefore the walls of the tube collapsing. SABS 460 category one – 28mm to 108mm is ideally suited to the drawing of “T” joints.

SANS 460 category 2:

A half hard, heavy gauge tube with glorious bending qualities. This category is additionally used beneath ground under traditional conditions i.e. non-aggressive soils. this can be the sole category that may be bent by mistreatment an interior Bending Spring. Care ought to be taken once putting in a tube underground. The tube ought to be protected against external corrosion mistreatment CXP tape. SABS 460 category a pair of – 28mm to 108mm is ideally suited to the drawing of “T” joints.

SANS 460 category 3:

This category may be a serious, thick-walled, half exhausting copper tube with glorious bending qualities, designed specifically for underground use wherever soil movement takes place. Care ought to be taken once putting in a tube underground and it ought to be protected against external corrosion mistreatment CXP tape.

CTA Blue Tube:

A hard drawn copper tube for higher than ground use solely. Designed for higher chloride-bearing waters and is employed to avoid kind one corroding corrosion. Any amendment of direction mistreatment Blue Tube ought to be created by mistreatment fittings. Blue Tube 28mm – 108mm undergoes a pressure check additionally as a further improved method before getting into the native market.
