Pentagon Steel India is a renowned manufacturer, supplier, and exporter of slip-on flanges (SORF) in India, offering products in various materials such as stainless steel (304/304L, 310/310S, 316/316L, 317/317L, 321/321H, 347/347H, 446), alloy steel, carbon steel, duplex steel, copper nickel alloy, hastelloy, titanium, alloy 20, monel, and inconel.
Slip-On Flanges are designed to slide over the pipe and are welded both inside and outside to provide strength and prevent leaks. They are commonly used in low-pressure applications where the risk of high-stress loads is minimal. These flanges are easy to install and align, making them an economical choice for piping systems requiring frequent maintenance or replacements.
The ASME B16.5 standard governs the dimensions and pressure ratings for Slip-On Flanges, ensuring they meet the highest quality and safety standards. These flanges are widely used in industries such as petrochemical, oil and gas, chemical processing, power generation, and water treatment, where a secure and reliable connection is essential.
Slip-on flanges are ideal for applications involving low-temperature and low-pressure systems. Their design allows for easier installation than other flange types, as they do not require precise cutting or alignment of the pipe. Pentagon Steel India offers slip-on flanges in a range of materials to suit different industrial needs, providing durable and reliable solutions for a variety of environments.
With a strong commitment to quality, precision engineering, and customer satisfaction, Pentagon Steel India ensures that its Slip-On Flanges deliver optimal performance, meeting the demanding requirements of both domestic and international clients.
We are a manufacturer and exporter of stainless steel flanges, alloy steel flanges, carbon steel flanges, duplex steel flanges, monel flanges, and Inconel flanges.
