Nonferrous piping is a term used to describe piping systems or pipes that are not made of ferrous metals. Ferrous metals contain iron, whereas nonferrous metals do not have significant amounts of iron. Because of its corrosion resistance and other desirable properties, nonferrous piping is widely used in a variety of industrial, commercial, and residential applications. The following are some key characteristics and examples of nonferrous piping materials: Nonferrous Piping Characteristics: Corrosion Resistance: Nonferrous metals are more corrosion resistant than ferrous metals, making them suitable for environments where moisture or corrosive substances are present. Nonferrous piping materials are frequently lighter in weight than ferrous piping materials, which can make handling and installation easier. Conductivity: Nonferrous metals such as copper and aluminium are excellent conductors of electricity and heat, making them ideal for use in electrical and HVAC systems. Nonferrous metals are easily formed and shaped, allowing the manufacture of intricate pipe designs and fittings. Nonferrous Piping Materials Examples: Copper: Because of its excellent corrosion resistance, heat conductivity, and antimicrobial properties, copper piping is widely used in plumbing and HVAC systems. It comes in a variety of shapes and sizes, including rigid copper pipes and flexible copper tubing. Aluminium pipes are lightweight and resistant to corrosion. They are commonly used in HVAC systems and for the transportation of certain chemicals. Conductivity: Some nonferrous metals, such as copper and aluminium, have a high conductivity. Brass: Brass is a copper and zinc alloy. It has a high corrosion resistance and is commonly used in water supply and gas distribution systems. Brass pipes can be yellow or reddish in colour. Bronze is an alloy composed of copper and other elements such as tin or aluminium. It is known for its durability and is used in marine applications as well as the transport of corrosive fluids. PVC (Polyvinyl Chloride): PVC pipes are non-metallic and made of a synthetic plastic material. PVC, while not a metal, is a nonferrous piping material that is widely used in plumbing and drainage systems. PE (Polyethylene) and PP (Polypropylene) are thermoplastic materials that are used in the manufacture of nonmetallic pipes. They are lightweight, corrosion-resistant, and widely used. Nonferrous piping materials are selected based on the application's specific requirements. Their corrosion resistance, conductivity, and other properties make them desirable in a variety of industries, including construction, manufacturing, and infrastructure development.
A pipe spool refers to a prefabricated section of a piping system. This includes the pipe, fittings and flanges that are pre-assembled. They are pre assembled because this can be done in a controlled environment.
The term "pipe spool" or "spool piece" refers to a prefabricated section of a piping system that includes the pipe, fittings and flanges that are pre-assembled in the fabrication facility and then transported to the field. The reason for pre-assembly is that hoists, gauges, material and tools are available for the assembly in a controlled environment. The size of the spool pieces is limited by factors related to transportation to the site and ability to handle the spool piece at the site during assembly.

*Any flange having different MOC bears the rating with respect to international standards like ANSI B16.5.*It is a designed pressure that a flange can withstand.*For example a flange is having the following specification:25NBX150#,FORGED CARBON STEEL as per ANSI B16.5is having 150 psi flange rating.It can withstand 150 psig pressure safely.(Noting that in most cases the pressure-temperature charts of a given spec will allow for normal operating pressure to far exceed the class rating at ambient temperature. For example a 150# flange in A105 Carbon Steel will rate for 285PSI at -20 to 100 Degree F. For more information see www.texasflange.com The original intent was to class the parts to safely hold the given pressure at relatively high temperature. Since often times the operating temperatures are much lower the flanges can usually be used well above their given rate. When in doubt take your design criteria to a company that deals in it and ask for the specifics.)*Pipe flanges that are made to standards called out by ASME/ANSI B16.5 or ASME/ANSI B16.47 are typically made from forged materials and have machined surfaces. They are typically in "Pressure Classes" such as 150#, 300#, 600#, 900# 1500#; however, ASME B16.47 still recognizes the 75# or "Class 75" flange for certain low pressure and low temperature applications. These "Pressure Classes" have both pressure and temperature ratings for specific materials. The flange faces are made to standardized dimensions and are typically "flat face" "raised face" "tongue and grove" or "ring joint" styles, although other obscure styles may be permitted. Flange designs are available as "welding neck" "slip-on" "lap joint" "socket weld" "threaded" and also "blind flange". The gasket type and bolt type are generally specified by the standard(s); however, sometimes the standards refer to the ASME Boiler and Pressure Vessel Code (B&PVC) for details ( see ASME Code Section VIII Division 1 - Appendix 2 ). These flanges are recognized by ASME Pipe Codes such as ASME B31.1 Power Piping, and ASME B31.3 Process Piping. Materials for flanges are usually under ASME designation: SA-105 , SA-266 or SA-182.*Please visit following link and download the software, you will get both pressure v/s temperature rating of flange:
For branching of one size lesser of run pipe, Stub On is preferred. For other branching less than one size of run pipe, Stub In is preferred. The design is based on ASME B31.3

What the difference between process piping and power piping?
Because in single stub method stub position has to be adjustible which create error......this is notin the case of double stub position method.........
pipe = one piping = a system of piping arrangements
