Adhered with materials such as steel pipe, as a rule of life due to corrosion is determined by the degree of retting. Corrosive effects combine with mechanical wear of pipe wall thickness tapering to and stresses over time as a result of the pipe causes the fracture or rupture. Corrosion as a result of the leakage of small holes in some cases there may be local. Severity of corrosion of pipe materials environment and depend on the fluid being transported through the pipe. What would be effective for corrosive environments and withstand corrosion in certain media time is not yet precisely determined. Therefore, the dirty water pipes depending on the type of material can withstand corrosive environments, how long it is difficult to predict in advance.Stuck pipe in plastic materials of the above factors affecting service life is somewhat different. Iron and steel pipes, plastic pipes for corrosive environments listed do not make any impact on. Chemical resistance of plastics directly depends on polymer degradation. As known to all the organic materials such as plastics decays over time.This degradation process UV radiation, such as thermal oxidation and water absorption is affected by events. To prevent or delay degradation carbon black, stabilizers, anti-oxidizing agents and pigments called participate in the refinery environment.
'D' symbol shown with plastic pipes and fittings the internal pressure is exerted from the outside in the absence of any mechanical action and when used with the indicated concentrations of chemicals in a change in the properties do not occur in a negative way.
