Abstract
A corrosion resistant tubular system is formed of a length of pipe in which each of the opposed ends terminate in a reduced external diameter integral tubular lip portion and, spaced from the lip portion, increased diameter external threads compared to the tubular lip portion, the lip portion having an external circumferential frusto-conical surface and a tubular coupling having internal threads adjacent each of the ends thereof and having, spaced inwardly from each of the internal threads a reduced internal diameter circumferential sealing surface that is tapered in a frusto-conical shape, the interior of the tubing and the coupling being formed of corrosion resistant metal alloy. When assembled a telescopic mating relationship is established between the external conical surface of the pipe and the internal conical surface of the coupling.
