Veer Flanges are based in the central parts of the Indian continent and are one of the major producers and distributors of quality flanges with specialization in ANSI B16.36 flanges. Veer Flanges is fully dedicated to engineering accuracy and production quality to deliver products that are long lasting and dependable enough to suit various industrial requirements. The company has a good record of following strict international regulations and its clients include the oil and gas, petrochemicals and power generation among other clients. Veer Flanges has been a trusted company of businesses that need high-quality flange solutions because of its obsession with timely delivery.
ANSI B16.36 flanges are normally produced using high quality materials like carbon steel, stainless steel, alloy steel which has a good resistant to corrosion and has high mechanical strength. Some of the common grade materials that are used are ASTM A105, A182 F304, F316 depending on the particular application requirements of the material. Such flanges have a higher tensile strength and yield strength as well as toughness and are thus applicable in harsh environments. The ANSI B16-36 flanges have been designed to work in high stress environments with mainly orifice and pressure ejection services being the primary applications of these flanged fittings.
Veer Flanges, a leading supplier in Kolkata, India, offers an extensive selection of ANSI B16.36 Flanges, including weld neck flanges, slip-on flanges, blind flanges, threaded flanges, and lap joint flanges. Designed for diverse industrial applications, our high-quality inventory and commitment to exceptional service make us a trusted choice for flange products in the region.

ANSI B16.36 flanges are mostly applied in piping systems where characterization of the flow is important or in those where relief of pressure is important. These flanges specifically designed to receive orifice plates are particularly used to measure accurately the flow rate of gas, liquid or steam. They are commonly used in oil and gas, chemical processing plants, power generation and water treatment. ANSI B16.36 flanges are commonly known to work well in harsh environments which expose them to high pressures and temperatures. They also facilitate the incorporation of pressure taps, and they can easily be linked with the control systems in order to achieve effective and sound management of the processes.
