Copper wire
Standard:TSh 64-05755737-141
Production cycle:
- preparation of coils of copper rod for drawing;
- emulsion preparation;
- preparation of dies in a drawing machine;
- refueling drawing machine;
- installation of a receiving coil;
- wire drawing;
- remove the take-up coil.
Application range:
The wire is intended for the manufacture of cable and wire products, as well as for other electrical purposes.
Form and packing:
The mass of a piece of wire is not less than 40 kg. Copper round electrical wire is produced in accordance with the requirements of TSh 64-05755737-141.
Copper pipes
Standard: Ts 00193950-006:2014
Production cycle:
- cathode copper smelting with adding the phosphorous-copper alloy for de-oxidation;
- discharge of copper pieces;
- rolling and drawing the copper pieces – in case of need: making the internal valley;
- winding the copper tubes onto coils (spiral, layer-by-layer ordered), and making the linear sections;
- annealing the copper tubes;
- packaging.
Application range:
Copper tubes are used in cold and hot water lines, heating systems, gas pipelines, and other infrastructure systems, and also in refrigerating equipment and heat exchangers.
Form and packing:
The mass of the tubes in coils must be 80 kg to 300 kg. The tubes in coils and stacks are packed with polyethylene film and placed into wooden boxes on pallets or into corrugated cardboard boxes according to GOST 7376. The packing is carried out either on pallets as per GOST 9557, or without pallets for tubes as the pieces, using blocks with cross section at least 50 x 50 mm, tied up with a wire, having the diameter at least 0.3 x 30 mm, or with the use of package straps.
The general-purpose copper seamless tubes with cold deformed circular cross section are manufactured according to the requirements of Ts 00193950-006.
The mechanical properties of the tubes must comply with the following requirements:
| Tube nominal outside diameter, mm | Delivery form | Material state | Ultimate strength σв, MPa (kgf\mm2), no less than | Specific elongation δ5, % no less than |
|---|---|---|---|---|
| 3.0 to 19.0 inclusive | in coils | soft | 210 (21) | 36 |
| 3.0 to 44.0 inclusive | in pieces | half-hard | 240 (25) | 11 |
| 3.0 to 44.0 inclusive | in pieces | hard | 280 (29) | 3 |
