Kalpataru Piping Solutions is a popular trader of Blind Flanges, where the process of making it is highly specialised and complex. Stainless Steel Blind Flanges is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. These Carbon Steel Blind Flanges are trusted for their various salient features like corrosion resistance, durability and high tensile strength. Alloy Steel Blind Flanges is a metal alloy consisting mostly of iron, in addition to small amounts of carbon, depending on the grade and quality of the steel. Super Duplex Steel Blind Flanges are made by combining carbon steel with one or several alloying elements, such as manganese, silicon, nickel, titanium, copper, chromium and aluminium. Nickel Alloy Blind Flanges also contains niobium for stabilization against sensitization and resultant intergranular corrosion. Inconel Blind Flanges is tailor-made as per the customer’s specification and end application. Monel Blind Flanges is any type of steel to which one or more elements besides carbon have been intentionally added, to produce a desired physical property or characteristic. Common elements that are added to make Hastelloy Blind Flanges are molybdenum, manganese, nickel, silicon, boron, chromium, and vanadium. Titanium Blind Flanges is the top choice for any sort of situation where a combination of high strength, light weight, good corrosion resistance and high toughness are required. Copper Nickel Blind Flanges can be used in biomedical applications such as implantable components due to its biocompatibility, good fatigue strength and low modulus.
