From the heart of Hamilton, New Zealand, Neesham Flanges has built a reputation as a trusted partner in the industrial supply chain. We specialise in the manufacturing and supply of high-performance alloy steel orifice flanges, crafted to meet the demanding needs of various sectors. Our commitment lies in delivering not just a product, but a reliable solution that ensures precision and durability for your critical flow measurement systems, backed by local expertise and a dedication to quality that sets us apart.
Creating a robust orifice flange starts with the right material composition. Our alloy steel flanges are primarily crafted from grades like A182 F5, F9, or F11, which incorporate elements like chromium and molybdenum. This specific blend gives them superior mechanical properties, including excellent tensile strength and exceptional resistance to creep and corrosion, especially under high-temperature and high-pressure conditions. This inherent toughness ensures they maintain their integrity and dimensional stability in the most challenging operational environments.
Neesham Flanges, a premier supplier in Hamilton, New Zealand, specializes in high-quality Alloy Steel Orifice Flanges, valued for their exceptional durability, corrosion resistance, precise engineering, and suitability across diverse industrial applications.

Alloy steel orifice flanges are most commonly employed by industries for the precise measurement of flow and controlling the same. These are mounted with orifice plates, thereby assisting in flow rate measurement for liquids, gas, or steam flowing through pipeline. Due to their toughness, temperature resistance, and corrosion resistant property, the alloy steel orifice flanges find their way in chemical process, oil, and gas processing, power, petrochemical, etc., industries. Their heavy-duty build guarantees accurate pressure drop and flow calculations, rendering them vital to effective system monitoring and regulation in harsh environments.
