From the heart of Hamilton’s industrial community, Latham Steel has built a reputation as a trusted partner for quality steel solutions. We are proud to specialise in the supply and distribution of Alloy Steel WP12 Pipe Fittings, offering local industry a reliable source for these critical components. Our focus is on providing robust, dependable products that meet the rigorous demands of our clients, backed by the expertise and service you can only get from a New Zealand-owned and operated manufacturer.
The strength of these fittings comes from their specific composition, primarily a chromium-molybdenum blend. This alloy recipe gives WP12 its notable resistance to high temperatures and pressure-induced stress, making it far more resilient than standard carbon steel. The material maintains excellent tensile strength and good ductility, which allows it to handle the physical challenges of demanding systems without compromising its structural integrity. Essentially, it’s engineered to perform reliably under tough conditions where other materials might fail.

We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
You’ll typically find these fittings hard at work in high-temperature power generation plants and critical petrochemical refineries. They are essential for constructing pipelines that carry steam, hot gases, and other process fluids where heat and pressure are constant factors. Their reliability makes them a go-to choice for connecting essential system components, ensuring the safe and efficient operation of industrial processes that form the backbone of our energy and manufacturing sectors. This is where their specialised performance truly proves its value.
