Double cavity PVC pipe extrusion line is widely used in construction projects (double-cavity drainage/ventilation ducts), municipal pipe networks (rainwater and sewage diversion systems), agricultural irrigation (water and fertilizer dual-pipeline transportation) and industrial fields (acid-base medium dual-path transmission). Its double-cavity structure can realize fluid isolation transmission, meet the dual needs of modern engineering for space utilization and functionality, and is especially suitable for high-rise residential buildings, underground integrated pipe corridors and other scenes.

Double cavity PVC pipe production line: efficient and intelligent pipe production solution:

Double cavity synchronous molding: equipped with customized double-cavity molds, it can extrude two independent cavity pipes at one time, and the production efficiency is increased by more than 50% compared with the traditional single-cavity line.
Intelligent temperature control system: adopts a multi-stage temperature control module to accurately control the plasticizing temperature of the raw materials to ensure that the inner and outer walls of the pipe are smooth and the thickness is uniform.
Modular design: Each process (batching, extrusion, cooling, traction) is independently controllable, supports fast switching of specifications, and is suitable for the production of multi-size pipes from Φ16-Φ1000mm.
Energy saving and consumption reduction: The main machine adopts a permanent magnet synchronous motor, which reduces energy consumption by 30% compared with traditional models. With the waste heat recovery system, production costs are further reduced.
Stable quality: Full closed-loop control, real-time monitoring of pipe diameter error (≤±0.3mm) through an online laser diameter gauge, and the qualified rate of finished products is over 99%.
Convenient operation: Integrated PLC touch system, supports one-button start and stop, parameter memory storage, and reduces the threshold for manual operation.
