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.
[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.
Japanese koi carp are coldwater fish. The term coldwater fish can have different meanings in different contexts.. In the context of fishkeeping, it refers to ornamental fish species that tolerate the temperatures of a typical indoor aquarium well and do not require a heater to remain active, as opposed to tropical fish whom need a heater to survive in the room temperatures of temperate climates;
Chlorinated polyvinyl chloride (CPVC) is produced through exposing PVC to the continued free-radical chlorination reaction that originally formulates the PVC polymer. The chlorination reaction continues to add chlorine atoms to the polymer hydrocarbon backbone until most commercial applications reach a percent range between 56 and 74% total ...
For a tropical fish tank, maintaining a warm environmental temperature ranging between 75 and 86 °F (24 to 30 °C) enables different tropical fish to thrive at different temperatures. [2] Aquarium substrate usually consists of sand or gravel. Aquarium substrate is important for the fish's health and replicating their natural environment.

Atlantic wolffish are primarily stationary fish, rarely moving from their rocky homes. They are benthic dwellers, living on the hard ocean floor, frequently seen in nooks and small caves. They like cold water, at depths of 20 to 500 m (66–1,640 ft). [12] They are usually found in water temperatures of −1 to 11 °C (30–52 °F).
The roach, or rutilus roach (Rutilus rutilus), also known as the common roach, is a fresh- and brackish-water fish of the family Cyprinidae, native to most of Europe and western Asia. Fish called roach can be any species of the genera Rutilus, Leucos and Hesperoleucus, depending on locality. The plural of the term is also roach. [3]
