CARBON STEEL TUBE & PIPET-tube’s carbon steel tubes and pipes are used in mechanical and pressure applications, most commonly in steam, water, gas and air lines as well as in a heat recovery steam generator (HRSG). An HRSG is a heat exchanger, used in combined cycle power stations, which recovers heat from hot gases coming from a gas turbine. It produces steam used to drive a steam turbine that generates electricity. HRSG tubes operate at high pressures and temperatures for long periods of time and must guarantee excellent creep, corrosion, and steam oxidation resistance.

COPPER ALLOYTUBE The excellent corrosion resistance of copper alloys has long been recognized by the engineering community. This is due to the formation of a protective oxide film, which when combined with the inherent antifouling characteristics and high thermal conductivity results in their wide use. Typical applications include the large tonnage multistage flash evaporators for desalting plants, power utility surface condensers and petrochemical plant heat exchangers.

SEAMLESS DUPLEX TUBE & PIPEIn power plant condensers, duplex tubes consisting of an inner titanium layer with outer copper-nickel alloys are employed. This enables the use of copper’s beneficial mechanical and chemical properties (e.g., stress corrosion cracking, ammonia attack) along with titanium’s excellent corrosion resistance.A duplex tube with inner aluminium brass or copper-nickel and outer stainless or mild steel can be used for cooling in the oil refining and petrochemical industries.
