Jiangyin Chengchen Pipe Industry Co., Ltd. offers "Chengchen" HDPE siphon drainage pipes, HDPE indoor drainage pipes, and all DPE indoor drainage materials, produced in full compliance with CJ/T250-2007 standards using 100% new materials. No waste materials are added, ensuring the quality meets national industry standards. These products are suitable for various building roof siphon rainwater drainage systems and indoor drainage systems (same-level drainage systems).
Pipes are the most critical component of both siphon roof rainwater drainage systems and building interior drainage systems. The variation in pipe diameter can accelerate rainwater discharge and flow rate; therefore, it is essential to ensure the system's safety, reliability, and efficient, continuous operation. As a specialized drainage system, the siphon system operates under a negative pressure state within the pipes during normal operation. Consequently, the pipe walls must have adequate pressure-bearing capacity, and pipe joints must be completely sealed to prevent air from entering and forming air pockets, which would disrupt the siphon action. Additionally, the pipes must have high fire resistance, strive to minimize noise, absorb vibrations, withstand external impacts, and accommodate deformation caused by temperature changes.
Same-level drainage refers to the situation where the drainage pipes of sanitary appliances (waste cross-pipes and branch pipes) in the bathroom do not pass through the floor into other rooms. The flat construction within the same floor ensures that the discharge of wastewater and waste meets or exceeds that of similar and other drainage methods, smoothly entering the main drainage trunk (main waste stack). In case of a need for cleaning and unblocking, the problem can be solved within the suite on the same floor. Abbreviated as "same-level installation," also known as same-level drainage.Same-level drainage is a toilet featureDrainage SystemA novel technique in one of the layers involves the internal laying of drainage pipes, using a shared water seal pipe fitting instead of numerous P-bends and S-bends. The overall structure is rational, thus minimizing clogs and easy to clean and unblock.
Our company produces and sells HDPE indoor drainage pipes in sizes DN50, 66, 75, 90, 110. For siphon roof rainwater drainage systems, we also offer HDPE siphon drainage pipes in sizes DN125, 160, 200, 250, 315. Sales prices are determined based on raw material costs, engineering purchase quantities, and payment methods, placing us at a moderate price point within the industry. Our quality is not inferior to any brand's similar products and can be inspected by quality supervision departments (random inspections available).
