Custom Spray Nozzles – When the Australian Navy was refurbishing one of its ships built in the 1950s, it struck a difficulty in replacing old nozzles.

The ship had around 250 nozzles to replace, and it was immediately clear they were unlike any styles currently manufactured today. Making the task of understanding how they worked was made particularly challenging by the fact that the original nozzles had been painted over many times, making them difficult to disassemble.

“We carefully applied paint thinner to gradually remove all the old paint, then pulled the nozzles apart to understand how they worked,” said Mr Cooper. “We discovered there were three different designs of nozzles and we examined all the parts of each to fully determine how they worked together.”

Adding to the challenge, the ship needed to return to sea within a short period of time, creating a slim window in which Tecpro could manufacture replacements.

“The nozzles were quite complex in their design so we drew on our team’s extensive skills in this area,” said Mr Cooper. “After we created a series of detailed technical drawings for each of the three nozzle types, we had 250 new nozzles manufactured from bronze, as this best suits a maritime environment. We also met the delivery date set for the project.”

Tecpro had previously worked on other Australian Navy projects, which included creating nozzles specifically designed to wash the windows of naval ships with greater effectiveness.

“For the bespoke nozzle project, the Navy needed nozzles that would precisely match the dimensions and functionality of the nozzles being replaced,” said Mr Cooper. “We were approached because of our experience, knowledge and capability to come up with a solution that could be relied on to be correct.”

Tecpro offers a bespoke design and fabrication service for hard-to-source or custom spray nozzles. It also stocks a variety of ready-made nozzles for a wide range of industrial applications.
