Title: pipe manufacturing and its type

Pipe manufacturing and types
What is piping?
  • piping is a system of pipes used to
    convey fluids (liquids and gases) from one
    location to another. The engineering discipline
    of piping design studies the efficient transport
    of fluid
  • Industrial process piping (and accompanying
    in-line components) can be manufactured
    from wood, fiberglass, glass, steel, aluminum, pla
    stic, copper, and concrete. The in-line
    components, known as fittings,3 valves, and
    other devices, typically sense and control
    the pressure, flow rate and temperature of the
    transmitted fluid, and usually are included in
    the field of piping design (or piping
    engineering). Piping systems are documented
    in piping and instrumentation diagrams (PIDs).
    If necessary, pipes can be cleaned by the tube
    cleaning process.

Generally, industrial piping engineering has
three major subfields
  • Piping material
  • Piping design
  • Stress analysis

Stress analysis
  • Process piping and power piping are typically
    checked by pipe stress engineers to verify that
    the routing, nozzle loads, hangers, and supports
    are properly placed and selected such that
    allowable pipe stress is not exceeded under
    different loads such as sustained loads,
    operating loads, pressure testing loads, etc., as
    stipulated by the ASME B31, EN 13480 or any other
    applicable codes and standards. It is necessary
    to evaluate the mechanical behavior of the piping
    under regular loads (internal pressure and
    thermal stresses) as well under occasional and
    intermittent loading cases such as earthquake,
    high wind or special vibration, and water hammer.
    This evaluation is usually performed with the
    assistance of a specialized (finite element)
    pipe stress analysis computer programs such as
  • In cryogenic pipe supports, most steel become
    more brittle as the temperature decreases from
    normal operating conditions, so it is necessary
    to know the temperature distribution for
    cryogenic conditions. Steel structures will have
    areas of high stress that may be caused by sharp
    corners in the design, or inclusions in the

  • The material with which a pipe is manufactured
    often forms as the basis for choosing any pipe.
    Materials that are used for manufacturing pipes
  • Carbon steel
  • ASTM A252 Spec Grade 1, Grade 2, Grade 3 Steel
    Pile Pipe
  • Low temperature service carbon steel
  • Stainless steel
  • Nonferrous metals, e.g. cupro-nickel, tantalum lin
    ed, etc.
  • Nonmetallic, e.g. tempered glass, Teflon lined, PV
    C, etc.

  • There are certain standard codes that need to be
    followed while designing or manufacturing any
    piping system. Organizations that promulgate
    piping standards include
  • ASME - The American Society of Mechanical
    Engineers - B31 seriesASME B31.1 Power piping
    (steam piping etc.)
  • ASME B31.3 Process piping
  • ASME B31.4 Pipeline Transportation Systems for
    Liquid Hydrocarbons and Other Liquids
  • ASME B31.5 Refrigeration piping and heat transfer
  • And further more.

There are three basic types of plastic pipes
  • Solid wall pipe
  • Extruded pipes consisting of one layer of a
    homogeneous matrix of thermoplastic material
    which is ready for use in a pipeline
  • Structured wall pipe
  • Structured-wall pipes and fittings are products
    which have an optimized design with regard to
    material usage to achieve the physical,
    mechanical and performance requirements.
    Structured Wall Pipes are tailor made solutions
    of piping systems, for a variety of applications
    and in most cases developed in cooperation with

  • Barrier pipe
  • Pipe incorporating a flexible metallic layer as
    the middle of three bonded layers. Barrier pipe
    is used, for example, to provide additional
    protection for the contents passing through the
    pipe (particularly drinking water) from
    aggressive chemicals or other pollution when laid
    in ground contaminated by previous use.
  • Most plastic pipe systems are made from
    thermoplastic materials. The production method
    involves melting the material, shaping and then
    cooling. Pipes are normally produced by extrusion.
