Pipeline Ancillaries

These are often neglected to save costs; but strainers, stop valves, check valves, separators, gauge glasses and vacuum breakers all have their part to play in an efficient steam system. This block explains why, and explores the different types available.

  1. Isolation Valves - Linear Movement

    Isolation valves are used for diverting process media, facilitating maintenance, equipment removal and shutdown. The operation, application and construction of gate, globe, piston and diaphragm valves are studied in this tutorial.

  2. Isolation Valves - Rotary Movement

    Isolation valves are used for diverting process media, facilitating maintenance, equipment removal and shutdown. The operation, application and construction of rotary movement (quarter turn) valves, including ball valves and butterfly valves, are covered in this tutorial.

  3. Check Valves

    Check (non-return) valves are installed in pipelines to allow flow in one direction only; helping to protect equipment and processes. The operation, benefits, applications and selection of different designs, including lift, disc, swing and wafer check valves are explained in this tutorial.

  4. Strainers

    Strainers arrest pipeline debris such as scale, rust, jointing compound and weld metal in pipelines, protecting equipment and processes. This tutorial considers the range of strainer and filter types in use and how to size and select them for different applications.

  5. Separators

    'Wet' steam is a major concern in a steam system as it can cause process and maintenance problems, including lower productivity, erosion and corrosion. Separators are designed to efficiently remove the moisture from steam flow. The application and selection of different types are considered here.

  6. Gauges, Sight Glasses, Vacuum Breakers

    These small items of equipment have a variety of important applications throughout steam systems and process equipment. The different types available are studied in this tutorial.
