Flanges are classified based on Pressure – temperature ratings as: A. 150 # B. 300 # C. 400 # D. 600 # E. 900 # F. 1500 # G. 2500 # Pressure temperature rating carts in the standard ASME16.5 specify the non-shock working gauge pressure to which the flange can be subjected t ... + Read more

How can flanges be classified based on facing?

Flanges are classified based on facing as: A. Flat face. (FF) B. Raised face. (R/F) C. Tongue and groove. (T/G) D. Male and female. (M/F) E. Ring type joint. (RTJ) Flange faces Different types of flange faces are used as the contact surfaces to seat the sealing gasket material. ASME ... + Read more

How can flanges be classified based on face finish?

Flanges are classified based on face finish as: A. Smooth finish B. Stock finish Flange face finish The ASME b16.5 code requires that the flange face (raised face and flat face) has a specific roughness to ensure that this surface be compatible with the gasket and provide a high quality ... + Read more

What is the difference between pipe and tube?

The difference between steel tubes and steel pipes: 1. Pipe Diameter and Tube Diameter Steel tube Steel tube is generally used for structural purposes and the OD is an important and exact number. Steel tube size is specified by OD and the wall thickness (WT); and the measured OD and stated OD are general ... + Read more

What is detail of nominal pipe size?

Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. The name NPS is based on the earlier “Iron Pipe Size” (IPS) system. That IPS system was established to designate the pipe size. The size represented the appr ... + Read more

What are details of butt weld fittings?

Buttweld Fittings A pipe fitting is defined as a part used in a piping system, for changing direction, branching or for change of pipe diameter, and which is mechanically joined to the system. There are many different types of fittings and they are the same in all sizes and schedules as the pipe. ... + Read more

What are details of ASME B16.11 socket weld fittings?

Socket Weld fittings 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 ... + Read more

What are details of ASME B16.11 threaded fittings?

Threaded Fittings Threaded joints probably represent the oldest method of joining piping systems. Like Socket Weld fittings, threaded fittings are mainly used for small pipe diameters (Small Bore Piping); generally for piping whose nominal diameter is NPS 2 or smaller. The dimensional stand ... + Read more
