Fittings

When it comes to choosing a steel fitting, your primary options are stainless steel or carbon steel. Carbon steel contains anywhere from 0.04% to 1.50% carbon. Stainless steel is a metal alloy containing iron and must contain at least 10.5% chromium. Generally, there are different types of pipe fitting used in piping. The main fitting components used in piping work are Elbow, Tee, Reducer, Union, Coupling, Cross, Cap, Swage Nipple, Plug, Bush, Expansion Joint, Adapters, Olet ( Weldolet, Sockolet, Elbolet, Thredolet, Nipolet, Letrolet, Sweepolet), Stream Traps, Long Radius Bend, Flanges and Valves etc. The standard fittings are either forging or wrought. Only the seamless pipes are used to wrought fittings.

Buttweld pipe fittings comprise of long radius elbow, concentric reducer, eccentric reducers, and Tees etc. Butt weld stainless steel and carbon steel fittings are an important part of the industrial piping system to change direction, branch off or to mechanically join equipment to the system. Buttweld fittings are sold in nominal pipe sizes with specified pipe schedule. Butt welded Pipe fittings such as carbon steel and stainless steel offers many advantages compared to threaded and socket weld fittings.

A butt weld pipe fitting is designed to be welded on site at its end(s) to connect pipe(s) together and allow a change in direction or pipe diameter, or branching or ending. This fitting then becomes part of a system for transporting fluids (oil, gas, steam, chemicals, …) in a safe and efficient manner, over short or long distances. Other types of fittings can be threaded or socket welded.

Fittings are used wherever liquids, gases, chemicals, and other fluids are created, processed, transported, or used. Fittings are sometimes thicker than their connecting pipes to meet performance requirements or due to manufacturing reasons. Due to fitting geometry, stress is very different when compared to a pipe. Using extra material is often necessary to compensate for such additional stress, especially for tees and tight curve elbows. Fitting manufacturers may not always stock plates or pipes for all metal grades or sizes. When responding to an order, manufacturers always use the right metal or alloy but sometimes made with a next-higher available plate or pipe size while still respecting specified inside diameters.

To reach the best performance ( resistance to various types of corrosive fluids, operating temperature ) at acceptable costs, many metals have found unique niche applications in fittings.

We Global International offers these fittings in a variety of materials, such as copper, cast iron, brass, galvanized, PVC and stainless steel. We also provide a wide selection of connection types including threaded, sweat, compression, flare, progress etc.
