A short summary of this paper. Pipe fitting Pipe fitting is the occupation of installing or repairing piping or tubing systems that convey liquid, gas, and occasionally solid materials. This work involves selecting and preparing pipe or tubing, joining it together by various means, and the location and repair of leaks.

Fitters work with a variety of pipe and tubing materials including several types of plastic, copper, steel, iron, aluminium, clay, and lead. Flange Flang Flange e is piping piping compo componen nentt that that funct function ions s to link link betwe between en the pipes pipes with with the the othe other r components such as valve, strainer, expansion joint, tools instruments, etc..

Besides these functions in the design of special flange installed for maintenance break flange. In terms of the strength of the pressure and temperature, is classified in the flange of the rating are: , , , , , , , and A valve is a device device that regulates regulates the flow of a fluid gases, gases, fluidized fluidized solids, slurries, or liquids liquids by opening, closing, or partially obstructing various passageways.

Valves Valves are technically pipe fittings, but are usually discussed as a separate category. Valves Valves are also found in the human body. For example, there are several which control the flow of blood in the chambers of the heart and maintain the correct pumping action see heart valve article.

Oil and gas, power generation, mining, water reticulation, sewerage and chemical manufacturing are the industries in which the majority of valves are used. Plumbing valves, such as taps for hot and cold water are the most noticeable types of valves. Other valves encountered on a daily basis include gas control valves on cookers and barbecues, small valves fitted to washing machines and dishwashers, and safety devices fitted to hot water systems.

Valves may be operated manually, either by a hand wheel, lever or pedal. Valves may also be automatic, driven by changes in pressure, temperature or flow. These changes may act upon a diaphram or a piston which in turn activates the valve, examples of this type of valve found commonly are safety valves fitted to hot water systems or steam boilers.

More complex control systems using valves requiring automatic control based on an external input i. An actuator will stroke the valve depending on its input and set-up, allowing the valve to be positioned accurately, and allowing control over a variety of requirements. S units. The Standard is limited to flanges and flanged fittings made from cast or forged materials, and blind flanges and certain reducing flanges made from cast, forged, or plate materials. Also included in this Standard are requirements and recommendations regarding flange bolting, flange gaskets, and flange joints.

Certain requirements also pertain to wrought or cast plugs, bushings, couplings, and caps. This standard covers spiral-wound metal gaskets and metal jacketed gaskets for use with raised face and flat face flanges.

It provides requirements for fitting ends suitable for soldering. It includes requirements for welding bevels, for external and internal shaping of heavy-wall components, and for preparation of internal ends including dimensions and tolerances. American Bearing Manufacturers Association - Wikipedia The American Bearing Manufacturers Association is an industry trade group that deals with all aspects of bearing technology.

It was founded in as an ABMA - American Bearing Manufacturers Association ABMA's mission is to provide leadership, advocacy and education with a focus on membership value, industry outreach and issues impacting the global bearing ABMA Represents American brush manufacturers through enhancing industry knowledge and providing networking opportunities.

ABMA's vision is to be the premier national association and voice of the American bearing industry. ABMA's mission is to provide leadership, Founded in , ABMA has a long, rich
