Hebei pvc bellows, Xiong Wang Thai (certified), Hebei District, pvc bellows provided by Xiong Wang Thai Plastic Products Factory. Xiong Wang Thai Plastic Products Factory (www.wangtai668.com) is specialized in the "plastic tube, MPP power tube, CPVC pipe electricity, irrigation pipes, HDPE pipes, p" of the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Fengjing Li. Depending on the structure of the plastic bellows, bellows can be divided into single wall and double wall corrugated pipe bellows. Single wall corrugated plastic pipe plastic pipe means inner and outer walls have corrugated pipe, with high rigidity, can be bent, infinite scroll installation. Double-wall corrugated pipe refers to the outer wall is smooth and has a corrugated (corrugated shape for right angles, trapezoidal, sinusoidal, etc.) of plastic pipe, which is made out of corrugated while the outer wall and an inner wall of a sintered layer of smooth extruded . It is all in addition to ordinary plastic pvc corrugated pipe corrosion good price, high insulation, outside wall smooth flow resistance characteristics of small pvc bellows specifications, due to the use of a special hollow ring stiffness and good strength and toughness. Meet the same strength and stiffness requirements under double wall corrugated pipe than ordinary plastic pipe material savings of 30% -50%, with good technical and economic pvc corrugated pipe production plant, and easy transportation and installation pvc bellows, reducing construction workers labor intensity, but also reduces the total investment of the project, but around the small curvature.
