Pipe Fittings

A valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves are technically fittings, but are usually discussed as a separate category. In an open valve, fluid flows in a direction from higher pressure to lower pressure.

Valves have many uses, including controlling water for irrigation, industrial uses for controlling processes, residential uses such as on/off and pressure control to dish and clothes washers and taps in the home. Even aerosols have a tiny valve built in. Valves are also used in the military and transport sectors. In HVAC ductwork and other near-atmospheric air flows, valves are instead called dampers. In compressed air systems, however, valves are used with the most common type being ball valves. Valves are found in virtually every industrial process, including water and sewage processing, mining, power generation, processing of oil, gas and petroleum, food manufacturing, chemical and plastic manufacturing and many other fields.

Valves are quite diverse and may be classified into a number of basic types. Valves may also be classified by how they are actuated:

Hydraulic
Pneumatic
Manual
Solenoid valve
Motor

Alloy Steel Fittings are extensively used in the installation of pipelines for re- directing the material flow. Made from the best grades of alloy steel, these fittings have excellent strength to sustain highly hazardous chemicals and gases. They are specially made to suit sensitive environment in power generation and nuclear industries. These are designed and finished precisely without any defect as the toxic materials these elbow carry can be hazardous if leaked.

We have wide range of sizes, pressure ratings, surface finish and wall thickness in our elbows.

Best suited for use in nuclear and power generation plants, these ensure quick and reliable pipeline installation with leak proof tight joints. Stability in dimensions, resistance against chemicals, low friction loss and smooth inner surface are some of the key features in these alloy steel fittings.

Concentric reducer is used to join pipe sections or tube sections on the same axis. The concentric reducer is cone-shaped, and is used when there is a shift in diameter between pipes. For example, when a 1" pipe transitions into a 3/4" pipe and the top or bottom of the pipe doesn't need to remain level. This pipe reducer may be used when there is a single diameter change or multiple diameter changes. Unlike eccentric reducers, concentric reducers have a common center line. Concentric reducers are useful when cavitation is present. Eccentricity occurs when the centerline is offset. This are used to properly reduce into and out of circulating pumps the concentric reducer pipe fitting also allows both the inlet and outlet ends to align to a common center line. Some of the important parameters used to select a concentric reducer are pressure/vacuum, max temp compression, approximate force, elongation etc. They are manufactured in various alloys, schedules, sizes and flange configurations. Concentric reducers frequently trap air when used at the suction of the pump. Concentric reducer save installation space and reduce costs.

Material: Carbon steel, alloy steel, stainless steel          Surface Treatment: Transparent oil, rust-proof black oil or hot galvanized.

Applications: Some of the industries where they find application are oil, gas, petrochemical, onshore and offshore sectors.

It is short length of pipe, which has one end that is flared outwards & the other end prepared to be welded to pipe of the same nominal pipe size material & of a similar wall thickness.

A Socket Weld is a pipe attachment detail in which a pipe is inserted into a recessed area of a Valve, fitting or flange. In contrast to buttweld fittings, Socket Weld fittings are mainly used for small pipe diameters (Small Bore Piping); generally, for piping whose nominal diameter is NPS 2 or smaller.

To join pipe to Valves and fittings or to other sections of pipe, fillet-type seal welds be used. Socket Welded Joints construction is a good choice wherever the benefits of high leakage integrity and great structural strength are important design considerations.

Fatigue resistance is lower than that in butt-welded construction due to the use of fillet welds and abrupt fitting geometry, but it is still better than that of most mechanical joining methods.

Some details of Socket Weld fittings

SW Fittings are family of high-pressure fittings are used in various industrial processes.

They are used for lines conveying flammable, toxic or expensive material where no leakage can be permitted, and for steam 300 to 600 PSI.

They are used only in conjunction with ASME Pipe and are available in the same size range.

They are used in areas where pipe-work is permanent and are designed to provide good flow characteristics.

They are produced to several ASTM standards and are manufactured in accordance with ASME B16.11. The B16.11 standard covers pressure-temperature ratings, dimensions, tolerances, marking, and material requirements for forged carbon and alloy steel. Acceptable material forms are forgings, bars, seamless pipe, and seamless tubes which conform to the fitting’s chemical requirements, melting practices, and mechanical property requirements of ASTM A105, A182, or A350.

They are available in three pressure ratings: Class 3000, 6000 and 9000.

Temporary tack welding is no needed for alignment, because in principle the fitting ensures proper alignment.

The weld metal cannot penetrate into the bore of the pipe.

They can be used in place of threaded fittings, so the risk of leakage is much smaller
