Jiangyin Chengchen Pipe Industry Co., Ltd. produces HDPE siphon drainage pipes (also known as siphon roof drainage pipes), utilizing advanced Shanghai Jinwei pipe extruders from both domestic and international markets. These pipes are made with high-quality domestic or imported high-density polyethylene raw materials, featuring advanced barrier-type screws and forced feeding extrusion systems to ensure thorough melting of the material. The production line is equipped with automatic computer control systems, including ultrasonic scanning devices, grain weight measurement controls, and wall thickness monitoring controllers, dynamically controlling the product during production to ensure the quality of every meter of pipe. The origin of the siphon drainage system product: Early drainage systems used traditional gravity drainage systems, which had drawbacks such as requiring a large number of rainwater vertical pipes and larger rainwater pipe diameters. The siphon rainwater discharge system was introduced to address these issues. The siphon drainage system utilizes the siphon principle for drainage, employing roof siphon rainwater funnels to separate air from water. Initially, due to the force of gravity, a vacuum is created inside the rainwater pipes. When the water inside the pipes is in a pressure flow state, a siphon phenomenon is formed, continuously draining the water until the rainwater pipes reach a full flow state. During rainfall, the continuous siphon action allows the entire system to quickly discharge rainwater from the roof. As an important component of the siphon rainwater discharge system, HDPE siphon pipes have also seen significant development...
