Not all copper alloys are created equal - so it’s important to verify their composition when using them in raw water applications.
Brass is an alloy of copper and zinc. The proportions of each give brass different mechanical properties. In short, the reason for the copper is that it is unreactive, however it is very malleable and easily shaped and on the other hand, zinc is reactive but very strong and durable. By combining the two and creating brass, we have the “best of both worlds” with a product that is unreactive and strong – perfect for plumbing fittings and valves
Whether you have an apprentice you’d like to train, or an experienced installer that needs a refresh, check out our new article which covers the correct priming and cementing process, common misconceptions about primer, and photos showing the consequences of not using primer.
Some of us are familiar with situations where stainless-steel pipelines have corroded, or more specifically cracked, on the welds. But we didn’t know it had a name, let alone why it happened or how to avoid it.
Intergranular corrosion is called IGC for short and also known as ‘Intergranular Stress Corrosion Cracking’. It causes significant problems across industry yet isn’t given the attention it deserves.
So, why and how does it occur, and what are the solutions? Let’s put it under the microscope.
A few cows to global powerhouse in 200 years
Since the early 1800’s the dairy industry in New Zealand has gone from farmers keeping a few domestic cows on bush blocks to now being a world leader accounting for 3% of total dairy production worldwide. Many of the most exciting innovations to influence the dairy industry globally were invented by kiwis. Waterworks are proud to have been involved in the development of this industry over the last 35 years.
Read on to see how NZ dairy has become what it is today, and where the future might take us.
