Provided are: a pipe-shaped integrally molded article which is formed by molding a polyphenylene sulfide resin composition, and which has, at one or more portions thereof, at least one selected from different-shape sections, bent sections, and different-diameter sections, the pipe-shaped integrally molded article being characterized in that the total length L (mm) thereof is 1000 or more, and the ratio (L/D) of the total length L (mm) to the outer diameter D (mm) of the pipe-shaped integrally molded article is 20 or more: and a production method for the pipe-shaped integrally molded article. According to the present invention, it is possible to efficiently provide a pipe-shaped integrally molded article having a desired large length and including a three-dimensionally complicated shape, by using a PPS resin composition having excellent heat resistance and chemical resistance.

The disclosed technology relates to a plastic compound suitable for preparing articles, such as pipe, with good physical properties, such as impact strength, and resistance to environmental stress cracking (ESC). In particular, the technology relates to a vinyl chloride resin, which includes chlorinated polyvinyl chloride (“CPVC”) homopolymer. Furthermore, the invention relates to vinyl chloride homopolymer compounds containing the vinyl chloride homopolymer resin, and articles made from such compounds, which compounds meet 23447 cell classifications under ASTM D1784.
