Based in the industrious heart of Hamilton, New Zealand, Neesham Flanges has built a reputation for precision and reliability in the demanding field of energy sector components. We specialize in the manufacturing and supply of API 6B flanges, products that are crafted with an unwavering commitment to meeting the highest international standards. Our team understands that in high-pressure environments, there is no room for compromise, which is why we deliver fittings that our clients in New Zealand and abroad can trust for integrity and performance.
The API 6B Flange is engineered from robust materials like carbon steel, alloy steel, or stainless steel, each chosen for its specific strength and corrosion resistance. These flanges are then heat-treated to achieve precise mechanical properties, including high tensile and yield strength, ensuring they can withstand extreme pressures and harsh operating conditions without failing. This rigorous attention to material composition and treatment is what guarantees the flange’s durability and long service life in the most challenging applications.
