Flow in valves and fittings - Pipe Flow Calculations

The resistance coefficient K for a given type of valves or fittings, tends to vary with size as does friction factor for straight clean commercial steel pipe at the same flow conditions. Some resistances in piping like sudden or gradual contractions and enlargements, as well as pipe entrances or exists are geometrically similar.

Reliability of Plumbing Fittings - Threaded vs ...

28-10-2015· Compression fittings can be used in high pressure applications and may even become more reliable as pressure is increased as the pressure tends to expand the tube against the ferrule. Although compression fittings are generally considered more reliable than threaded fittings, there are some potential problems.

Pressure Loss in Steel Pipes Schedule 40

The tables below can be used to estimate friction loss or pressure drop for water flowing through ASME/ANSI B36.10/19 schedule 40 steel pipes.

Steel Pipe - an overview | ScienceDirect Topics

During 1970s, the author first replaced steel pipes by high-density polyethylene (HDPE) pipes that had many advantages as listed below: 1. It is lighter than steel and can be supplied in 20–200 ft length depending on the diameter. A crew of four can easily lay more than 1000 ft in a shift of 8 h compared with about 300 ft for heavy steel pipes.
