Abstract:A discussion is made of several kinds of organic nonmetallic tubing materials,which are commonly applied in petrochemical industry unit . By comparing the physical mechanical capacity and corrosion proof capacity,combining the practical application of nonmetallic tubing in Lanzhou petrochemical complex,the application scopes and the localization of these tubing materials are synthetically analyzed.In the end,the especial capacity of CPVC is discussed emphatically,with the hope to offer some reference for chemical industry to select tubing material rationally according to the corrosible circumstances.
