Stainless steel and cast iron slip-on flanges are manufactured to meet specifications as required by the client. They are designed for fitting pipes of different sizes and are used for industrial applications. They are manufactured from several materials such as carbon steel, stainless steel, cast iron, alloy steel and ductile iron. In some cases, a flange may also be forged or made from a plate.
In some cases, Slip-on Raised Face flanges can be a weld neck flanges. A weld neck flange is manufactured by welding together two pieces of pipe using fillet welding. In the case of a slip-on flange, a ring is placed on the pipe and the flange is slipped over the pipe. This is the most economical way to mat different-sized pipes. It is also a popular choice for low-pressure applications.
Applications of Slip-on Raised Face flanges (SORF)
Slip-on flanges are often preferred over weld neck flanges because they can be manufactured at a lower cost. They can be manufactured with a bore designed to fit the size of the pipe. They are also welded to provide strength. They are also made with a uniform surface finish so that there is no possibility of rusting. They are also manufactured using a TIG welding process so that they can achieve the desired strength and durability.
They are used in the industrial, chemical and petrochemical industries as well as in agriculture. They are available in both a plain face and a raised face design. They are also used in the pharmaceutical industry. They are manufactured in a variety of shapes, including round, square, oval and square-headed. They are also manufactured in duplex and super duplex steel. A slip-on raised face flange is also available in a flat-face design.
A slip-on flange is used in the petrochemical, chemical, power generation, petrochemical, oil refinery, water and wastewater treatment, and process industries.
Uses and Advantages of Slip-on Raised Face flanges (SORF)
It is also used in the petroleum and natural gas industries. They are also used in automotive exhaust systems, as they connect the engine to the pipe. These flanges are manufactured in a wide range of sizes and are available in both standard and metric dimensions. They are usually made of stainless steel or a nickel alloy. These flanges are usually welded using a full penetration V-weld, which provides excellent stress distribution and reinforcement for high-temperature and sub-zero applications.
Slip-on flanges have a larger bore than the pipe itself so that the flange can be slid over the pipe. They also have a long tapered hub, which provides reinforcement and reduces turbulence at the joint. The long taper also provides a smooth transition from the flange thickness to the pipe wall thickness.
A slip-on flange is also used for fitting two pipes together. It is a cheaper alternative to a weld neck flange and has a lifespan of about one-third the life of a weld neck flange. In addition, a slip-on flange is a cost-effective solution for mating different-sized pipes, as it does not require a high degree of accuracy when cutting the pipe.
