Pipe Fittings

Instrument Pipe Fittings

Instrument pipe fittings are a vital part of an instrumentation system. They are used to transfer and control system flow and measure the pressure and temperature of the system. They also provide the desired system calibration. Many instrumentation pipe fitting components are interchangeable and intermixable across brands and suppliers.

With Omni Services, we are here to help you choose the right fitting and brand for your systems and applications. There are various types of pipe fittings: Adapters, couplings, elbows, tees, flanges, valves, reducers, sleeves etc. which are used to connect pipes, tubes, flared, pneumatic and other fittings for various configurations. See below the different types of pipe fittings Omni has available. 

Elbows  are used to change the direction of the pipeline. They come in various angles, most commonly 45 degrees and 90 degrees but can also be found in other angles as needed. Elbows help in navigating pipes around obstacles or changing the direction of flow.

Tees have a T-shaped configuration and are used to create branch connections in a pipeline. They allow fluids to flow in three directions and are often used in plumbing systems to connect fixtures or equipment. Reducer fittings are used to connect pipes of different sizes.

They can be either concentric reducers (maintain a consistent centerline) or eccentric reducers (one end is offset from the other). Reducers help transition from larger to smaller pipe sizes or vice versa. Cross fittings have four connection points and are used to create a 90-degree branch connection in a pipe system.

They allow fluid or gas to flow in four directions and are less common than other fittings. Couplings are used to join two pipes of the same size in a straight line. They are often used when pipes need to be extended or joined temporarily. Unions are similar to couplings but provide a way to disassemble the pipes without cutting. They consist of three parts: two threaded ends and a nut that joins them. Unions are useful for maintenance and repair work.

Caps are used to seal the end of a pipe. They are commonly used for closing off a pipe temporarily, capping unused lines, or as protective covers. Nipples are short pieces of pipe with threads on both ends. They are used to extend or connect pipe segments, typically in confined spaces.

Flanges are used to connect pipes to other equipment or components, such as valves, pumps, or tanks. They provide a secure and easily disassembled connection and are often used in high-pressure or critical applications. Socket-weld fittings are designed for use with socket-welded pipes.

They have a socket (recessed area) that the pipe end fits into and is then welded for a strong connection. Threaded fittings have threads on both the inside and outside surfaces, allowing them to be screwed onto pipes without the need for welding. They are common in low-pressure applications.

Weld Fittings

Welded pipe fittings are components used in piping systems to connect and branch off, reduce pipe size, attach auxiliary equipment or redirect the flow of fluids, gasses, or other substances in a secure and leak-proof manner. These fittings are specifically designed for use with welded pipes, which are created by joining two pipe sections together through welding, as opposed to threaded or socket-welded fittings used with threaded or socket-welded pipes.

Welded pipe fittings are typically made from the same material as the pipes they connect. Common materials include carbon steel, stainless steel, alloy steel, and various other metals or alloys, depending on the application’s requirements. 

There are several types of welded pipe fittings, each serving a specific purpose in a piping system. Some common types include:

• Elbow
• Tee
• Reducers
• Caps
• Stub ends welded fittings
• Cross fittings
