  2. Cross-linked polyethylene - Wikipedia

    en.wikipedia.org/wiki/Cross-linked_polyethylene

    A cross-linked polyethylene (PEX) pipe. Cross-linked polyethylene, commonly abbreviated PEX, XPE or XLPE, is a form of polyethylene with cross-links.It is used predominantly in building services pipework systems, hydronic radiant heating and cooling systems, domestic water piping, insulation for high tension (high voltage) electrical cables, and baby play mats.

  3. Flow distribution in manifolds - Wikipedia

    en.wikipedia.org/wiki/Flow_distribution_in_manifolds

    The n is the number of ports and L the length of the manifold (Fig. 2). This is fundamental of manifold and network models. Thus, a T-junction (Fig. 3) can be represented by two Bernoulli equations according to two flow outlets. A flow in manifold can be represented by a channel network model.

  4. Cylinder manifold - Wikipedia

    en.wikipedia.org/wiki/Cylinder_manifold

    A cylinder manifold is system of pipes and valves for using a group of gas cylinders, or boil-off from vacuum insulated evaporators, to feed a single supply line.The advantages of the manifold system as compared with using a single cylinder are increased capacity and reliability, and also the possibility of a centralized supply for multiple users.

  5. Plastic pipework - Wikipedia

    en.wikipedia.org/wiki/Plastic_pipework

    Plastic Pipe lengths manufactured in Australia by extruding HDPE material.. Plastic pipe is a tubular section, or hollow cylinder, made of plastic.It is usually, but not necessarily, of circular cross-section, used mainly to convey substances which can flow—liquids and gases (fluids), slurries, powders and masses of small solids.

  6. Manifold (fluid mechanics) - Wikipedia

    en.wikipedia.org/wiki/Manifold_(fluid_mechanics)

    A component used to regulate fluid flow in a hydraulic system, thus controlling the transfer of power between actuators and pumps. Inlet manifold (or "intake manifold") An engine part that supplies the air or fuel/air mixture to the cylinders. Scuba manifold. In a scuba set, connects two or more diving cylinders. Vacuum gas manifold.

  7. List of abbreviations in oil and gas exploration and production

    CK – choke (a restriction in a flowline or a system, usually referring to a production choke during a test or the choke in the well control system) CL – core log; CLG – core log and graph; CM – choke module; CMC – crown mounted compensators; CMC – critical micelle concentration; CMP – common midpoint (geophysics)

  8. Isolation valve - Wikipedia

    en.wikipedia.org/wiki/Isolation_valve

    Isolation valve. An isolation valve is a valve in a fluid handling system that stops the flow of process media to a given location, usually for maintenance or safety purposes. [1] They can also be used to provide flow logic (selecting one flow path versus another), and to connect external equipment to a system. [2]

  9. Polyethylene - Wikipedia

    en.wikipedia.org/wiki/Polyethylene

    PEX is a medium- to high-density polyethylene containing cross-link bonds introduced into the polymer structure, changing the thermoplastic into a thermoset. The high-temperature properties of the polymer are improved, its flow is reduced, and its chemical resistance is enhanced.
