APPLICATION

Copper pipes are used as heat exchangers (air conditioners, refrigerating machines, heating) and when installing the gas and liquid transporting systems.

Copper pipes are used in:

  • Air conditioning systems (ASTM B280, ASTM B68, ASTM B75, EN 12735, AS 1571, JIS H3300)
  • Refrigeration systems (ASTM B280, ASTM B68, ASTM B75, EN 12735, AS 1571, JIS H3300)
  • Heating and water supply (ASTM B88, EN 1057)
  • Gas and oil lines
  • Transportation of liquids, CO2, and other gases (ASTM B88, EN 1057, GOST 617-2006)
  • Heat pumps
  • Solar panels
  • Boilers

FEATURES

The pipe material has high thermal conductivity and mechanical strength. Copper is resistant to oxidation, gas-tight, and easy to process. Pipes are connected to each other by fittings and soldered. The threaded connection is possible.

  • Permissible operating pressure: 30-140bar (depends on the thickness of the pipe/wall)
  • Melting point: 1084°C.
  • Permissible operating temperature: 250°C
  • Linear expansion coefficient: 0.017mm/m•K
  • Oxygen-tight
  • Withstand 1-3 cycles of freezing
  • Bacteriostatic On the pipe surface, microorganisms stop multiplying and die

The inner surfaces of copper tubes are compatible with freons and liquids used in heat transfer systems

Pipes are produced weld-free on special equipment made of refined copper C12200 (99.90% copper; 0.01-0.04 phosphorus). The alloy grade determines the thermal properties of the product.

The mechanical properties of pipes are affected by the quenching degree. Annealed pipes are soft, unannealed pipes are rigid. In heat exchangers, soft annealed pipes are used.

By type:

  • Smooth
  • With internal corrugation (improved heat transfer).
  • Covered with foamed polyethylene (improved thermal insulation)
  • Covered with polyethylene (higher protection)

Copper pipes are supplied with plastic plugs at the ends to keep the internal walls clean.

The pipes are packed in structured LWC coils or flat coils of 50m. Copper pipes of larger diameters are delivered in sections.

The products are free of manufacturing defects, thanks to multi-stage processing and strict output quality control. No refrigerant leakage.

Corrugated pipes

Pipes with internal corrugation are characterized by 65-100% larger surface area. The heat transfer coefficient of the corrugated pipes is 1.8-2 times higher than of smooth pipes.

They are used in air conditioning units and in applications requiring increased energy efficiency

Heat-insulating pipes

The pipes are covered with a double layer of foamed polyethylene with closed cells. The extruded thermal insulation layer is in tight contact with the pipe to prevent condensation.
The heat-insulating pipe withstands the action of ultraviolet light and has a low water absorption
