Comprehensive Details on Slip-On Flanges

Slip-on flanges are designed with a slightly larger bore than the connecting pipe, allowing the pipe to slide in easily for welding. This type of flange requires two fillet welds – one on the inside and one on the outside – for a secure fit. These flanges are particularly suitable for low to medium pressure systems, offering a cost-effective alternative to weld neck flanges without compromising on functionality. Widely used in industries such as oil and gas, water treatment, and chemical processing, slip-on flanges are available in stainless steel, mild steel, aluminum, and copper, catering to diverse industrial applications. The cost of slip-on flanges is typically lower than that of weld neck flanges, making them a preferred choice for projects with budget constraints.
