Einführung

Pipe flanges, including steel pipe flanges, are key parts used when you need to join steel pipe in a system. The slip-on flange, also called an SO flange, is well-known for its simple design that works well. This type does not need the exact same alignment as welding neck flanges. The slip-on flange is easy to put in place and costs less, so it is often used by people working with oil and gas. These flanges work well in low-pressure systems. They are also good because they fit well with many other pipe fittings. All this makes slip-on pipe flanges a great pick for modern piping systems where you need fittings that do many things.

What is an SO Flange?

An SO flange, which is also called a slip-on flange, is a kind of pipe fitting. This flange is made to slide easily over steel pipes, which makes connecting them simple. The inner diameter of the flange is a bit bigger than the outer diameter of the pipe. This lets you put the pipe into the flange bore without trouble. It gets fixed in place by fillet welding at the top and at the bottom of the flange. This gives a good, leak-free hold, which is important in low-pressure piping systems.

The shape of the slip-on flange makes it great for jobs that need fast and easy installation as well as easy alignment. You often see these flanges used in chemical processing, water treatment, and oil and gas areas. These flanges are known to be versatile, and they also save you money. They can be made from different materials, including carbon steel, stainless steel, or alloys. The choice of material depends on what mechanical properties you need for the job.

Key Features and Design of SO Flanges

Slip-on flanges have a flat flange face and a bigger inner diameter, so you can slide a steel pipe right into the flange bore. This smart design makes installation easy because the pipe does not need to line up in a very exact way before welding. You will find outer diameters from standard sizes like 2” and 4” to special options up to 60”.

Most slip-on flanges have a low hubbed hub. This helps make installing them simple and works well with pipelines, fittings, and pressure systems. The flange bore is big enough to let you weld smoothly and lowers the chance of not lining up during the job. When you use fillet welding at the bottom of the flange, it adds to the strength and helps keep the pipe joint from leaking.

Slip-on flanges come as raised face flanges, which give better support for the gasket, or as RTJ flanges made for high-pressure sealing. These flanges work well in many types of piping, which means they are used in all types of commercial and industrial jobs. Their flexibility lets people use them in many places.

Common Materials and Standards Used in the UK

Slip-on flanges use different materials based on what the job needs. Carbon steel flanges that meet ASTM A105 standards are often used in low-temperature settings. They are known for being cost-effective while also performing well. For jobs that need more durability, people use stainless steel flanges. They are good for high-pressure systems and follow ASTM A182 rules. Grades such as F304 and F316 are used to help the flanges resist corrosion.

The choice of material must also match key global standards like ASME B16.5 and British Standard BS 3293. These standards help to make sure there is good quality and fit in different pipelines, including those for socket fittings. They guide aspects like size, pressure levels, and the shape of the flange bore needed for fittings.

Slip-on flanges are also made by forging and casting. These ways of making them give the flanges solid mechanical properties to handle different industrial needs. Because they follow ASME, ASTM, and BS rules, slip-on flanges keep working well in places like chemical plants and water treatment areas. They are built for high durability and are made to connect tightly with other fittings in the pipeline.

Now, let’s move on and look at their detailed specifications and where you can use them.
