Slip On Flanges Class 150 & SORF Flange Class 150 Manufacturers & Suppliers in Mumbai, India


Fitwel Industries LLP is one of the leading independent manufacturer, supplier & exporter of High-quality slip on flanges manufacturer in mumbai, India & the world. SORF Flanges are ideal for lower pressure applications. Welding reduces the fabrication costs of these pipes. These are available in a wide variety of sizes and applications. Slip On flanges Class 150 are a popular type of pipe flange. These SORF Flanges Class 150 are typically provided with a raised or flat face. The flange bolt holes are aligned and the flange face squared to the pipe. Slip On Flange is available in sizes from 1/4” through to any size. We offer high-quality ASME/ANSI/DIN standard slip on flanges class 150 in India. We offer immediate delivery programs for standard sizes carbon steel slip on flanges and stainless steel slip on flanges.

Backed by a team of professionals, we are engaged in offering a wide range of Slip On Flanges to our esteemed clients. We are indulged in crafting slip on flanges that are precisely crafted with all expertise. Slip On Flanges are fitted over the pipe and then fillet welded. The calculated strength from a Slip On Flange under internal pressure is of the order of two-thirds that of Welding Neck flanges, and their life under fatigue is about one-third that of the latter. These are types of flanges that slide over the end of piping and then welded in place. The flanges is slipped over the pipe and then welded both inside and outside to provide sufficient strength and prevent leakage.

What is slip on flanges?

Slip On Flange is essentially a ring that is placed over the pipe end, with the flange face extending from the end of the pipe by enough distance to apply a weld bead on the inside diameter. The OD of slip on flange is also welded on the backside of the flange.

Where slip on flanges are used?

Slip on flanges are suitable for low-pressure applications and are easy to install and weld onto different pipes. In addition, welding helps to reduce manufacturing costs. Slip-on flanges do not require a large longitudinal space in the line to be mounted.

How are slip on flanges welded?

Slip-on fittings slip onto the end of the pipe. The flange is then welded around the contact points on the inside and outside of the pipe and the flange. Slip-on flanges are not considered as strong a joint as weld-neck or butt-welded connections.

Among the wide variety of forged flanges are some sliding types commonly called slip-on flanges. This is a type of flange that is low-cost and easy to install.

Main features of the slip-on flange

Slip-on flanges are known for their low materials cost and easy installation. One of the added advantages of these flanges is that they can also be used as lap-joint flanges if Type B or Type C ends are being handled.

There is a wide range of diameters and low-pressure models to choose from. Unlike welding neck flanges, this flange does not have a neck to rest on the pipe, and therefore double welding is necessary.

Slip-on flanges do not require a large longitudinal space in the line to be mounted. In addition, they do not require an exact cut in the pipe, and are less difficult to align.

Applications of slip-on flanges

They are mainly used for fluids at low pressure or with little risk of leakage. It is very common to find these flanges today in cooling water lines, firefighting water lines, low-pressure compressed air lines, and process lines for substances such as steam, oil, gas, condensates, etc. But always keeping in mind that the material to be distributed is at low pressure and the working conditions are not demanding.

Characteristics of slip-on flanges

Pros

  • Low cost
  • Ease of assembly and installation
  • They occupy the minimum longitudinal space for a flange.
  • They come in a wide range of diameters.

Cons

  • Not recommended for high pressure applications
  • Not recommended for use with hazardous fluids or gases
