Type Of Pipe Fittings
There are two type of pipe fittings buttweld pipe fiting and forged pipe fittings. Buttweld pipe fittings use in a diverting flow system, for modifying course of flow, extending or for change of channel separation. Furthermore, which is correctly joined to the structure of system. There are two sorts in pipe fittings i.e butt weld fittings and Forged steel fittings.
The piping components that support the piping process for directional change, change of size and branch connexions are known as piping fittings. Different pipe fittings per specification or process specifications perform various purposes. Pipe fittings are produced and procured separately as a single component. Pipe fittings from separate end connexions are linked to piping. In different uses, tube fittings play an significant role in the accurate operation of tubes and pipes. We will review in this article the description of various types of pipe fittings for pipelines and the plumbing industries.
These two categories involve many wide scope of types and different schedule sizes as per application requirements. Seamless pipe fittings and welded butt weld fittings with estimations running from 1″ to 48″. Forged steel pipe fittings are involve the size varies from ¼" to 4″ and with pressure classes 3.000 lbs, 6.000 lbs and 9.000 lbs.
Stainless Steel Butt Weld Fittings
We are follow the international safety, standard and advance technique for stainless steel Buttweld fittings, and product to match the safety enviourments. A channeling system using butt welding fittings has various basic inclinations over various structures. Welding is process in pipe fitting suggests that it is always leak proof and damages. The constant metal structure encircled among pipe and fitting adds solidarity to the system. Smooth internal surface and slow course changes reduce pressure adversities and roughness and farthest point the action of utilization and breaking down ,as welded structure utilizes at any rate space .
Elbow Pipe Fittings: Elbow fittings are changing the flow path in pipe systems. It sounds simple enough, but this allows immense versatility in the design of a piping system, as it saves space and keeps the pipes comfortable where they are to be. Without taking these factors into account, it is virtually impossible to develop a piping system. Common elbows have bends of 90°, 60°, 45°, and 22 1/2 degrees and used for turning purposes. The obstructions in the pipe can be connected to move around.
Reducer Pipe Fittings: A pipe reducing unit is an element in the pipelines used to decrease its size according to the inner diameter from large to small. The reduction length here is equal to the average diameter of the smaller and larger tube. For chemical factories and power plants, the use of a reducer takes place. It makes the tube system compact and reliable. It prevents any adversity or thermal deformation of the tube system. This prevents leakage of any kind and is easy to install when it is on the pressure cycle.
Cross Pipe fittings: Pipe crosses have one inlet and three inlets, often with solvent-solved socket or feminine-threaded ends, also known as four-way accessories. The ends are placed at 90 ° angles and the threads have a stable grip and safe link with the male pipes. Such attachments cause more stress on the tube when the temperature changes, since they are in the middle of four connection points. In general, fire sprinkler systems are used for cross fittings.

What is Schedule?
For stainless steel and nickel alloys pipe fittings of all estimations the outside diameter across (O.D.) remains commonly constant. The variation is only affects the inside diameter (I.D.). A schedule number is calculated based on :
Schedule = 1000 P/S
Where P = organization pressure (psi) & S = allowable stress (psi)
The higher the schedule number is, the thicker the channel . Since the outside diameter across of each channel size is organized or constant, a particular apparent pipe size will have changes in inside channel width depending upon the schedule reuirements.
Stainless Steel Forged Fittings Supplier
Screwed and Socket Weld Fittings is a part of Forged steel fittings. Any flow or piping system can be coupled using thread type of BSP and NPT (Class 3000 and 6000) high weightes fittings in Grade 316. The application of Socket weld fittings are high pressure enviourments and piping system ( 3000lb, 6000lb, 9000lb) , the high demand of Forged Fittings are commonly available in grade 304/304L and 316/316L.
