Pipe Fitting for Chemical Disposal Well utilizes a wind pattern which amplifies the tensile capacity of the pipe allowing it to easily contend with down hole service. The Pipe Fitting has a liner that provides enhanced chemical resistance and a higher operating temperature range. The Pipe Fitting can be used in wells as deep as 3,100 meters in temperatures as high as 120 ° C while injecting a hydrochloric acid solution. The Pipe Fitting for Chemical Disposal Well is used in chemical disposal wells which deal with aggressive waste streams generated as a by-product of chemical manufacturing facilities.
