Publisher Summary. This chapter summarizes ANSI buttweld fittings, which are used to change direction or join parts of a piping system.
Different types of buttweld fittings include elbows, reducing elbows, degree elbows, degree returns, tees, crosses, eccentric and concentric reducers, lap.

Piping class or Pipe Class is a document that specifies the type of the components such as a type of pipe, schedule, material, flange ratings, branch types, valve types and valve trim material, gasket and all the other components specific requirements to be used for different fluids under different operating conditions in a plant.
Flange joints require proper tightening to avoid the leak of the fluid from the joint. Bolt tightening sequence or torque sequence is key to achieve this.
Torque table provides the required value for bolt tightening. A complete torque tightening procedure.

Flange Specifications The standard flange drilling is normally PN16, on pipes and fittings for working pressures up to and including 16 Bar.
Other drilling configurations (PN10, PN25, PN40) require the corresponding number and size of bolts in a set for the specified drilling arrangement. Bolt sets (Extra Long) for PN16 flanges - DI x PE Joint.
It is basically flange part but covered under ASME B that is why it is considered as pipe fittings. Piping Union Unions are used as an alternative to flanges connection in low-pressure small bore piping where dismantling of the pipe is required more often.

THREADED FLANGE Threaded flanges are joined to pipes by screwing the pipe (which has a male thread, generally NPT per ASME B) onto the flange, without seam welds (in certain cases, though, small welds are applied to increase the strength of the connection).
Threaded flanges are available in sizes up to 4 inches and multiple pressure ratings, however, they are used, mostly, small size. Specifies requirements and dimensions for circular, plate blank, boss, integrally cast or forged and welding-neck type flanges or nominal sizes DN 15 to DN and their bolting for use on pipes, valves and fittings and other pressure-retaining equipment containing fluid at pressures up to kPa and at temperatures in the range °C to +°C.
AN AMERICAN NATIONAL STANDARD ASME B (Revision of ASME B) Pipe Flanges and Flanged Fittings NPS 1/2 Through NPS 24 Metric/Inch Standard. Stud bolt, nuts, machine bolts and washers are also known as bolting material or fastener.
Bolting is the term that used to tighten / create the flange joints connection. Tightening of the flange ensures the leak-proof connection between gasket & flanges. ASME flanges have a minimum four bolt hole and for higher diameter flanges, the number of bolt holes is always in multiples of four.
This Standard specifies requirements for circular flanges of nominal sizes DN 15 to DNinclusive, and their bolting for use on pipes, valves, fittings and other pressure-retaining equipment containing fluid at pressures up to 19 kPa and at temperatures in the range C to + flanges are manufactured from carbon steel, carbon-manganese steel, alloy steel, stainless steel.

Flanges are commonly used to connect valves into pipework making it easier for removal and maintenance. There are many common flange standards and flanges within the same standard can etiher be flat (commonly cast iron, ductile iron) or raised face (commonly cast steel and stainless steel).
Below is a reference table for critical flange dimensions to help identify what standard you have. The ASME - American Society of Mechanical Engineers - ASME/ANSI B16 Standards covers pipes and fittings in cast iron, cast bronze, wrought copper and steel.
