Seamless Pipes
Seamless pipes are in accordance with EEMUA 234/chapter 1. They are manufactured from hot extruded shells followed by cold work and annealing.

Welded Pipes
Longitudinally welded pipes are in accordance with EEMUA 234/chapter 2. They are manufactured from hot rolled or cold rolled and annealed sheet or plates in accordance with BS 2870, BS2875, ASTM B171 or ASTM B402. Mechanical testing is carried out in accordance with the standards above. The pipes are supplied in “as welded” condition.

Copper Nickel has a Yield Strength of 103 MPa (15000 psi). The Rockwell B Hardness of Copper nickel is 69. The Machinability of Copper nickel is 20. Copper Nickel 90/10 offers superb resistance to brackish water, biofouling in seawater, erosion and stress corrosion. It has superb welding and fabrication properties. As far as hydrogen embrittlement goes, 90/10 copper nickel has a very high resistance to this. Cu-Ni 90/10 is very popular for use in industrial, architectural and marine applications, as it has high ductility and toughness. The Elastic Modulus of Copper nickel is 152 GPa (22000 ksi). The Thermal Conductivity of Copper nickel is 32.9 W/mK (0.0900 BTU in/hr.ft². °F). 90/10 copper nickel has superb antimicrobial properties, which means that it has the capability to kill a huge range of microbes, up to 99.9%, including the likes of Clostridium difficile, E. coli, MRSA and influenza A (H1N1), within a span of just a couple of hours.
