Based in the Midlands in the UK, Brydon Pipes and Tubes is a leading manufacturer and supplier specializing in copper and nickel boiler tubing. Known for its exceptional resistance to seawater corrosion and high temperatures, copper nickel tubing is ideal for hot seawater, energy generation and industrial heat exchanger. We use water treatment providing precisely designed temperatures to exacting industry standards. Ensures reliable and operational efficiency With a commitment to efficient and timely delivery, businesses are provided with reliable solutions various.
Copper nickel boiler tubing is typically 70% copper and 30% nickel, with trace amounts of iron and manganese for increased strength and corrosion resistance. These materials provide excellent resistance to sea corrosion, and enhance it good for marine applications. Mechanically copper nickel boiler tubing exhibits high tensile strength, good ductility, and good thermal conductivity, ensuring excellent heat transfer. Benefits include resistance to stress corrosion cracking, biofouling and long service life , making it a reliable choice for boiler heat exchangers in marine and industrial power generation.
