Chlorinated polyvinyl chloride (CPVC) is a thermoplastic produced by chlorination of polyvinyl chloride (PVC) resin which is significantly more flexible and can withstand higher temperatures than standard PVC.

Uses include hot and cold water pipes, and industrial liquid handling.

Polyvinyl chloride, more correctly but unusually poly(vinyl chloride), commonly abbreviated PVC, is the world's third-most widely produced synthetic plastic polymer, after polyethylene and polypropylene.

Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures.

"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 outside diameter).

Specific pipe is identified by pipe diameter and another non-dimensional number for wall thickness referred to as the Schedule (Sched.

or Sch., for example – "2 inch diameter pipe, Schedule 40").

NPS is often incorrectly called National Pipe Size, due to confusion with national pipe thread (NPT).

The European and international designation equivalent to NPS is DN (diamètre nominal/nominal diameter/Durchmesser nach Norm), in which sizes are measured in millimetres, see ISO 6708.

The term NB (nominal bore) is also frequently used interchangeably with NPS.

A pipe is a tubular section or hollow cylinder, 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.

It can also be used for structural applications; hollow pipe is far stiffer per unit weight than solid members.

Adhesive may be used interchangeably with glue, cement, mucilage, or paste, and is any substance applied to one surface, or both surfaces, of two separate items that binds them together and resists their separation.

Adjectives may be used in conjunction with the word "adhesive" to describe properties based on the substance's physical or chemical form, the type of materials joined, or conditions under which it is applied.
