Pipe Fittings are Plumbing materials that support the course of flow in Adjustments such as elbows, tees. Changes the size of the tubing, for instance reducers, raising tees. Link different components such as couplings and disrupt flows such as caps. In piping different forms of pipe fitting are used. Elbow, Hat, Reducer, Union, Linking, Brace, Collar, Swage Nipple, Pipe, Brush, Extension Joint, Connectors, Olet (Weldolet, Sockolet, Elbowlet, Thredolet, Nipolet, Letrolet, Swepolet), Steam Traps, Broad Radius Snap, Flanges and Lock. The regular fittings are either hammered or cast. Wrought fittings are made utilizing only seamless pipes. The machine creates broad diameter welded fittings.
Forged pipe fittings (Socket Weld and Threaded) are created in compliance with the standards of ASME (American Society of Mechanical Engineers) B16.11, MSS SP-79\ 83\ 95\97 which BS3799, and are used to link pipes and pipelines for the nominal bore schedules. Forged Iron Pipe Fittings are accessible as fitting of the socket weld pipe or as threaded pipe fitting. Forged fittings are constructed of A105 (carbon steel), nickel or stainless steel alloy. Such fittings are stronger and thicker and are built for heavy industrial use. Forged Iron Pipe Fittings are available in pressure groups 2000 #, 3000 #, 6000 #, and 9000#.
Forged Fittings Manufacturing Processes
There are many production processes of Pipe Fittings that used to make Elbow, Tee, Reducers and other fittings for pipes. Fittings are made with filler content from Smooth Pipe and Welded Steel (ERW & EFW pipes cannot be used for constructed fittings). Large diameter Plate fittings are made.
Some of the different processes that are used in the manufacturing of the Forged Pipe Fittings are
-Monaka or Double weld seam Method
-Hydraulic Bulge method – Cold forming
-Hot forming or Extrusion Method
-Deep Drawing Method for caps
-Flare Method for Stub ends
Hot forming or Extrusion Method
Hot extrusion is a method in which forged pieces are created by pressing a hot billet through the opening of a molded die. This post addresses hot extrusion, both non-lubricated and lubricated. The two non-lubricated forms of hot extrusion are forward or overt extrusion, and reverse or indirect extrusion. Lubrication is needed here. In both lower temperature extrusions this lubrication should be achieved with glass powder in case of higher temperature extrusions and graphite or gasoline. While the hot extruded materials are widely favored, there are a few drawbacks associated with hot extrusion which are the expense and repair of extrusion machines.
Monaka or Double weld seam Method
One of the techniques used often to make Elbows from tiles. After symmetrically cutting two bits of raw material tiles, each pair is pushed and welded together, reminding us somewhat of the Japanese delicacy, “Monaka.” This approach extends to various fabrics, and may also be extended to large objects over 1 meter in diameter. To meet different Global requirements, it has two seams and advanced welding equipment in operation.
Hydraulic Bulge method – Cold forming
Hydroforming tube utilizes internal pressure and axial feeding to turn a tube into the ideal type. The finite-element approach can be used to forecast the outcomes of the operation. One of the most important parameters for tube hydroforming finite element research is the properties of the tube materials. The tensile test and the hydraulic bulge test are two ways of determining the tubular substance properties. To examine the finite element process for tube hydroforming in a state close to the real tube hydroforming, the properties of the tube content must be calculated by means of a hydraulic bulge check
Deep Drawing Method for caps
Some of the most popular methods of producing caps, where plate is cut in a circle and shaped by a deep draw. Deep drawing is the method of turning sheet metal storage, or blanks, into circular or irregular forms which are more than half of their diameters long. Deep drawing includes wrapping the blank metal around a tube and then placing it through a die called a moulding cutter.
A drawing press may be used to mold sheet metal into various forms and the finished design depends on where the blanks are placed in. The metal used in deep drawing shall be maleable as well as resistant to exposure to stress and strain.
Flare Method for Stub ends
Stub Ends or Lap Joint Flange are developed using flaring process. Flow end is a flare or flange face cut out. Stub ends are often provided by welding, where the forge block is machined to the final dimension.

What are forged fittings?
Forged fittings use hubs or ends for fillet welding to pipe. They are used for smaller pipes or one that will have high pressures passing through.
What is the difference between Wrought and forged Fittings?
The main difference between wrought and forged fittings is strength. Forged fittings are tougher than wrought fittings as they begin as a casting which is then forged which adds to its durability.
What manufacturing processes were applied to SS Forged Fittings?
There are four processes of manufacturing a SS forged fittings. First is Mandrel method, as the name suggests a curved mandrel is inserted into a length of pipe. Extrusion Method consists of a machine that has the mould of the fitting into which the pipe inserted and come out in the shape of a fittings.Next is the UO method in which a piece of sheet is cut out and then it is pressed on an anvil that has the inverted shape of a fittings. Hot Forming Method is somewhat similar to Extrusion Method, here a piece of pipe goes through a mould of the fittings and come out in the needed shape.
What is the difference between forged and cast brass fittings?
Forged fittings are pressed into shape while the metal is hot and generally have higher pressure ratings. Cast fittings are formed by pouring molten metal into a form and general have lower pressure capacity when compared to forged fittings.
Are pipings and pipe fittings the same?
No, fittings go over the pipe
How do you rectify leakage on pipe fittings threaded joints without removing the pipe fittings?
You cannot do that effectively without taking the fittings apart,
Can you use pressure fittings on three-quarter inch OD steel pipe for natural gas fittings for kitchen stove or do you always have to use threaded?
Not sure what you mean by pressure fittings. Threaded fittings for steel pipe are pressure fittings. Steel pipe with a 3/4" O.D. is known as 1/2" I.P.S. (Iron Pipe Size) pipe.
What is the means of A234 WPB?
A234 WPB is a code for pipe fittings. The code is a standard established by ASTM to refer to pipe fittings made of wrought carbon steel that can withstand moderate to high temperatures.
Where are places in Houston one can buy pipe fittings?
There are a few places in Houston where one can purchase pipe fittings. A good place to try is Pipe Fittings. Another good place to try is Home Depot.
Are pipe and pipe fittings can be different schedule?
No, they need to match.
What has the author Thomas S Walsh written?

What is pipe take off?
It is the measurement of fittings for piping. It is the measurement of fittings for piping.
