Copper (SF-Cu)

Widely used in marine and industrial heat exchangers. In addition to round tubes, copper can also be offered in integrally finned and corrugated rope sections. Good resistance to corrosion in fresh water. Working temperature up to 250 deg.-C. Cooling water speed 1.5 m/s.

(usually STOCK ITEM, for details please contact us on +44(0)1484-723402 or email: enquiries@abacus-tubes.co.uk)

Brass (CZ126) arsenic inhibited

Gives good service with clean mains, river and lake water where lack of severe corrosion conditions does not warrant the use of more expensive alloys.

(usually STOCK ITEM, for details please contact us on +44(0)1484-723402 or email: enquiries@abacus-tubes.co.uk)

Admiralty Brass (CuZn28 SN1) CZ111

Will operate successfully in steam condensers and coolers for land based stations where river waters are brackish and conditions are slightly acid or alkaline. Also resistant to sulphur-bearing gases. Cooling water speed 2.0 m/s; temperature up to c. 200 deg.-C.

Aluminium Brass (CuZn20 Al2) CZ110

Extensively used material and one of the most popular. This alloy forms a protective film which has self-healing properties. This film is dependant on oxygen dissolved in the water and will not renew itself in polluted or stagnant water. High resistance to corrosion in clean seawater or where land conditions are difficult. Cooling water speed 2.5 m/s; working temperature up to c. 250 deg.-C.

Cupro Nickel Alloy (CuNi10 Fe1 Mn) CN102

Widely used in condensers, coolers and heat exchangers where resistance to corrosion and erosion is paramount, yet maintaining a high thermal conductivity rate. To be used preferably in marine conditions. Forms a protective film which is multi-layered in flowing seawater. Resists marine bifouling. Cooling water speed 2.5 m/s; working temperature c. 250 deg.-C.

(usually STOCK ITEM, for details please contact us on +44(0)1484-723402 or email: enquiries@abacus-tubes.co.uk)

Cupro Nickel Alloy (CuNi 30 Mn1 Fe) CN107

Improved corrosion resistance and almost insensitive to stress corrosion, this alloy will give superior results in high velocity polluted water, including seawater. A reduced thermal conductivity level, but will retain its strength at moderately increased temperatures. Cooling water speed up to 4.5 m/s.
