Steel Pipe Flange Manufacturer & Exporter India
A Pipe Flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. Usually the materials include carbon steel flanges and stainless steel flanges. The choice of the material mainly dependent on the factors of the flange. For instance, stainless steel flanges are much long lasting and is necessary for heavy duty or tough use. On the other hand, plastic is more viable for use in the home because of its fair rate and uncomplicated inuaguration. The material for Steel flanges are under the designation of the American Society of Mechanical Engineers.
We percieve the customers demand and conforming supply with the help of quality assurance. We at Devdeep Steel Alloys one of the best Flange Manufacturers in India. Our product range include all types of pipe flanges and also according to customer requirement.
In addition, we can also produce the DIN flange, and the forgings according to the customers drawings, for example, rings and shafts.
Standards, Dimensions & Materials of Pipe Flanges.
Flanges General : The requirement for American National Standards Institute (ANSI) code for flanges and flanged fittings (ANSI B16.5 Flange) are as follows. A) The flange face must have specific roughness to ensure that the surface is compatible with the gasket. B) It should also provide a high quality seal to avoid accident.
Measure the size of a flange : All the possibilities of thread form, diameter, and pitch, are send machinist. You can also buy the thread pitch gauges and comparator and thread micrometer (to measure minor diameter) to fully define the thread. But this strategy may won’t help you in finding the ring. We mainly manufacture stainless steel flanges and carbon steel flanges.
Pressure Classes of Flanges : The concept of flange ratings likes clearly. The Class 300 flange are constructed with more metal and can withstand more pressure. Hence Class 300 flange can handle more pressure than a Class 150 flange. However, there are a number of factors that can impact the pressure capability of a flange. The Pressure Class or Rating for flanges are available in pounds and Kg. We use different names to indicate a Pressure Class of flange.
Most Common Flange Types
Slip on Flange (SOF) are made to slip over the outside of pipe or a long-tangent elbows, swages and reducers. As known the flange has unsatisfactory resistance to vibration and shock but it is uncomplicated to align.
The Socket Weld Flange is similar to a slip-on flange, except only one fillet weld is made to the pipe and flange. There are a also various contradictory procedure for confirming that the pipe has sufficient evacuation when welding.
The weld neck flange (WNF) is a pipe flange type that is usually used with pipes, as opposed to pressure vessels. The design of the flange allows for a full penetration weld at its base where it connects to the pipe and hub.
Threaded Flange can be connected to the pipe without welding, because of this main advantage they are employed in special circumstances. Sometimes one can also use seal weld in combination with the threaded flanges.
The purpose of Blind Flange is to close ends of piping systems. It is a type of round plate with perfect bolt holes at corner but no centre hold. To prepare positive closer use ANSI B16.5 blind flanges on ends of equipment valves and pipes.
A lap joint flange is a pipe flange that consists of two parts, a stub end and the backing flange. On a Lap Joint, the flange slides over the pipe and stub end is the connection where the gasket sits which is of same OD as raised face.
Flanges Face Type
The Raised Face Flange is the most common type used in process plant applications, and is easily to identify. It is referred to as a raised face because the gasket surfaces are raised above the bolting circle face.
A Flat Face Flange is a pipe flange that is machined flat and does not have a ridge like a raised face or ring type joint flange. The flat surface allows for the gasket to have full contact with the entire mating surface.
A Ring type joint Flange is a type of flange that uses a metal ring that sits in a hexagonal groove as a gasket to seal the flange pair. The raised face doesn’t serve as a way to contain the pressure.
