  2. Chlorinated polyvinyl chloride - Wikipedia

    en.wikipedia.org/wiki/Chlorinated_polyvinyl_chloride

    CPVC sprinkler pipe inside a firestop mock-up. Chlorinated polyvinyl chloride (CPVC) is a thermoplastic produced by chlorination of polyvinyl chloride (PVC) resin. CPVC is significantly more flexible than PVC, and can also withstand higher temperatures. Uses include hot and cold water delivery pipes and industrial liquid handling.

  3. Nominal Pipe Size - Wikipedia

    en.wikipedia.org/wiki/Nominal_Pipe_Size

    Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...

    The outside diameter was the important dimension for mating with fittings. The wall thickness on modern copper is usually thinner than 1 ⁄ 16-inch (1.6 mm), so the internal diameter is only "nominal" rather than a controlling dimension. [13] Newer pipe technologies sometimes adopted a sizing system as its own. PVC pipe uses the Nominal Pipe Size.

  5. Preferred metric sizes - Wikipedia

    en.wikipedia.org/wiki/Preferred_metric_sizes

    Machine screws with different thread diameters Hex key set with metric sizes from 2 mm to 10 mm according to sizes for use with ISO 262 screw sizes (except 3.5 mm for M6 internal set screw) For each size bolt or screw and type of head, there is a corresponding size driver prescribed by various ISO standards, including:

  6. Standard dimension ratio - Wikipedia

    en.wikipedia.org/wiki/Standard_dimension_ratio

    Standard dimension ratio (SDR) is a method of rating a pipe's durability against pressure.The standard dimension ratio describes the correlation between the pipe dimension and the thickness of the pipe wall.

  7. Piping and plumbing fitting - Wikipedia

    en.wikipedia.org/wiki/Piping_and_plumbing_fitting

    A reducer reduces the pipe size from a larger to a smaller bore (inner diameter). Alternatively, reducer may refer to any fitting which causes a change in pipe diameter. [15] This change may be intended to meet hydraulic flow requirements of the system or adapt to existing piping of a different size. The reduction length is usually equal to the ...

    en.wikipedia.org/wiki/Polyvinyl_chloride

    [37] [38] Buried PVC pipes in both water and sanitary sewer applications that are 100 mm (4 in) in diameter and larger are typically joined by means of a gasket-sealed joint. The most common type of gasket utilized in North America is a metal-reinforced elastomer, commonly referred to as a Rieber sealing system.

  9. British Standard Pipe - Wikipedia

    For a taper thread, it is the diameter at the "gauge length" (plus/minus one thread pitch) from the small end of the thread. The taper is 1:16, meaning that for each 16 units of measurement increase in the distance from the end, the diameter increases by 1 unit of measurement.
