What is Pipe Fittings?
Piping systems in several industries are never straight. Hence, they need to be manipulated in such a manner that is convenient for the buyer as well as to the application it is intended for. This being said, fittings are used to joining pipes in a system, such that they optimise the output. Pipe Fittings as whole envelopes several components that collectively form a piping system.
Other pipe fitting connection types include nipples, unions double-tapped bushings, plugs and barbs, all of which are familiar in the world of plumbing. Factory settings across the world are either horizontal or they are vertical. It is difficult to build connections in factories that have a vertical piping system. However, with the appropriate material selection and proper guidance of pipe fittings manufacturer in India, building these connections has become somewhat easier.

Different Types Of Pipe Fitting used in Piping System Or Pipe Connections
- Pipe Elbow
- Pipe Reducer
- Pipe Cap
- Pipe Tee
- Pipe Cross
- Stub Ends
The following Types of Pipe Fittings Used in Piping system include pipe caps, crosses, tees, elbows, reducers, adapters as well as olets. Popular among these fittings are elbows. Elbows are one of the most versatile fittings available across the world. Not only do they forge connections with vessels and pipes, but they also change the direction of flow. The direction could be customised if the buyer’s requirements.
Buttweld fittings are components that ensure a leak-proof solution to areas that are particularly prone to have leaks. The 45 Degree Elbow also have a gradual change from a smaller bore size to larger bore size. Which is why the level of stress caused during transportation of media across is considerably lower. Usually, ASME B16.9 fittings that do not permit for a smoother transition flow are more likely to fail and crack under stress.
45 Deg Elbow
45 Deg Elbow could be customized to an angle that best suits the application. While many buyers understand that using the correct material increases the longevity of the fitting, many times they prefer the use of the more basic Long Radius Elbow. The 45 degree and 90 degree elbows are standard elbows.
90 Degree Elbow
Thus, making the 90 Degree Elbow Fitting well suited for multiple applications including the oil and gas industry. This is for several reasons. Primary amongst them is the cost.
180 Degree Elbow
Usually, to improve the corrosion resistance property of the Sch 40 Deg Elbow, the most common practise across all sectors is to galvanize them. For non-standard degrees of angle the calculation is done with the length of the elbow, the Tan of the degree of angle and the elbow radius
Short Radius Elbow
While many buyers understand that using the correct material increases the longevity of the fitting, many times they prefer the use of the more basic Carbon Steel Long Radius Elbow.
Long Radius Elbow
The Long Radius Elbow is one of the commonly used pipe fittings to connect the pipes together while changing the direction of fluid flow. The elbows can cause pressure differences in high pressure lines and the stress and impact have to be taken into consideration when installing elbows.
Pipe Reducers are fittings that ease the transition between a smaller pipe size to larger pipe size. One of the main flaws of these fittings is that they are very likely to experience failure when the stress levels are elevated.
One is that they offer leak-proof transportation of the gas or fluid in the system and the other reason is that they have a structure that is more gradual and permits easy flow. The ASME B16.9 Concentric Reducer make it easy for the flow to move around easily without cracking.
ASME B16.9 Eccentric Reducer are conically shaped, thus they are capable of fitting between two different sized pipes and bridging their gap. The Buttweld Ecc Reducer is particularly well suited for those industries that have hydraulic requirements in their application.
Pipe cap is also in lay terms referred to as a pipe end, simply because the buyer uses an ASME B16.9 Cap at the end of a pipeline in a system. This fitting is known to be multi-functional. First, they are used to seal off a pipe, thus ensuring a leak-proof and safe form of connection. This feature is specifically important to industries that have high volumes of flammable or toxic compounds being transported across in their piping system.
In an application, the use of a tee fitting is to branch out or to change the directional flow of media. Because the resemble the letter T, the Buttweld Pipe Tee are such that each inlet/ outlet is perpendicular to each other. Or in simpler words, the outlet is branched at 90 degree angles. Like most fittings produced, the specified ASME B16.9 Tee follows the parameters set by this specification including its mechanical properties.
Testing is an integral procedure of these standards, particularly those belonging to the ASME because they provide proof that the product, which in this case is the ASME B16.9 Equal Tee will function at a particular temperature and pressure without compromising its tensile strength, mechanical properties or even its corrosion resistance properties.
One of the best surface treatment practises performed on the ASME B16.9 Reducing Tee is to galvanize them, which in turn offers a significant improvement over its non treated counterpart.
Amongst all the materials that could be used to produce the ASME B16.9 Straight Tee, the most commonly used variant is carbon steel. Carbon steel is not only cheap and tough but also has minimum resistance to corrosion, which could be improved by the use of various finishes.
Testing is an integral procedure of these standards, particularly those belonging to the ASME because they provide proof that the product, which in this case is the ASME B16.9 Barred Tee will function at a particular temperature and pressure without compromising its tensile strength, mechanical properties or even its corrosion resistance properties.
Manufacturers of the ASME B16.9 Lateral Tee are required to follow the testing requirements as well, to check the product conformance to the standard.
A ASME B16.9 Pipe Cross is a type of fitting that has four openings on one connection. Reducing Cross is the most type of Pipe cross.
The use of a ASME B16.9 Stub End is commonly seen with a lap joint flange. In combination, both the Lap joint flange as well as the Long Stub End may be used to replace welded flanges. This is especially in those instances where the assistance of a rotating reinforcement flange may be required.
