Hudson Flanges is a UK-based manufacturer and supplier of high quality reducing flanges as well as other industrial applications from Midland. Hudson Flanges is well-known for precision engineering and bespoke products. For piping systems Provides consistent solutions, involving smooth transitions from one pipe size to another With a focus on customer satisfaction, custom flanges with stringent industry standards meets for, guarantees durability and performance in harsh environments Their experience in all forms of flanges Makes it a trusted partner.
Reducing flanges are typically constructed from carbon steel, stainless steel, or steel alloys to guarantee durability and resistance to corrosion. These flanges are manufactured to join pipes of varying diameters, which facilitates a transition from one size to another with ease. Their technical properties comprise high tensile strength, high fatigue resistance and high impact resistance. Advantages of minimizing flanges also include saving costs, as they minimize the requirement for multiple fittings, are simpler to install, and maximize flow The weight of the piping system is minimized while maintaining system integrity and leak-induced functionality.
