Stainless Steel Flanges
A flange is a connecting mechanism that connects tubing, valves, pumps, and other machinery to form a piping structure. It also allows for a quick washing, evaluation, and modification. Typically, flanges are welded or bolted together. Pipe flanges are made of a variety of materials, including stainless steel, cast iron, copper, silver, bronze, rubber, and so on, although carbon steel produced and machined surfaces are the most prevalent.
Flanges come in a variety of sizes and diameters. The design of a flange is determined during the pipe selection process; in most cases, the flange is of the same kind as the pipe plug. Flanges are utilized in a variety of piping systems, depending on the material and application area. Stainless steel 304 and 316, for example, are suggested for use in severely corrosive situations. The Flange Selection Process is a completely distinct topic.
There are different types of flanges
Weld Neck Flanges
Weld Neck Flanges in Stainless Steel 304 are flanges that can be welded to the pipe ends. They have an extended neck that can be soldered to the pipe. A single full penetration of the V-shaped butt weld connects them.
High-pressure applications call for Weld Neck Flanges. These are also employed in low-temperature applications where there is no requirement for a hole in the piping system. The welded neck relieves pressure while also preventing turbulence and metal corrosion.
Slip-On Flange
The SS 310 Slip-on Flanges are connected to the piping systems with two Fillet welds. Both the inner and outer sides of the flange cavity are filled with two fillet welds. Slip-on flanges, also known as Hubbed flanges, are exceptionally narrow and small.
The pipe that passes through the flange usually has a smaller diameter than the Bore of the Slip-on flange. This makes it possible to use a fillet weld to secure the pipe.
Threaded Flange
Stainless steel 316 Without surface welding, threaded flanges are connected by screwing the wire onto the flange. Threaded flanges are also required in hazardous situations such as petrol stations and mines, where welding would be harmful.
Threaded flanges come in a variety of sizes and pressure levels up to 4 inches, but they’re mostly utilized in low-pressure, low-temperature applications like water and air utilities.
Lap Joint Flange
321 SS Except for the radius at the flange face crossing and the bore to fit the flanged part of the stub end, lap joint flanges are similar to slip-on flanges in shape.
Because the lap joint flange content may be of a lesser quality (typically carbon steel) than the stub end material, using lap joint flanges with stub ends is a cost-effective solution for stainless steel or nickel alloy pipes.
Blind Flange
904 SS Blind flanges by Stainless Steel 904l Flanges Supplier, unlike the other flange types, do not have a central aperture and are used to blind or close a tube, a valve/pressure vessel, and restrict fluid flow. Blind flanges give easy access to the pipeline since they can be untied to allow the operator to work within the pipe terminal.
Because of the weight of the framework and the bolting forces required, blind flanges are subjected to extreme mechanical stress.
