  • Sclairpipe

    A marine pipeline is usually assembled on land adjacent to the body of water in which it is to be installed If this is not practical, the pipe may be joined at another more accessible location and then floated to the installation site Long lengths of large diameter pipe have been towed up to 25 kilometers to the installation site...

  • GRE Pipes

    GRE pipes are comparatively lightweight, easy to handle and install The thermal conductivity of GRE pipes is low compared to steel and hence heat loss and insulation cost is minimizedGRE pipes also have a smooth internal surface enables high pipe flow capacity and reduces friction as well...

    Sep 25, 2009· The Tube & Pipe Journal became the first magazine dedicated to serving the metal tube and pipe industry in 1990 Today, it remains the only North American publication devoted to this industry, and it has become the most trusted source of information for tube and pipe professionals...

  • Caisson (engineering)

    In geotechnical engineering, a caisson (/ ˈ k eɪ s ə n / or / ˈ k eɪ s ɒ n /; borrowed from French caisson, from Italian cassone, meaning large box, an augmentative of cassa) is a watertight retaining structure used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, or for the repair of ships...

  • Cathodic protection

    Cathodic protection (CP) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell A simple method of protection connects the metal to be protected to a more easily corroded "sacial metal" to act as the anodeThe sacial metal then corrodes instead of the protected metal...

  • Compressed Air Receivers

    Note that in a compressed air system the pipe work also makes the purpose of a buffered volume There is no generally accepted method of sizing air receivers but a commonly used formula is based on the mass balance C p a t = V (p 1 - p 2) (1) that can be transformed to...
