The demand for lightweight, high-stiffness drainage pipes is rapidly increasing worldwide. At Zhangjiagang Lvima Technology Co., Ltd, we have been at the forefront of plastic pipe machinery innovation, providing advanced PVC pipe making machines and other specialized equipment designed to meet modern infrastructure challenges. This article will detail the core construction of a PVC double-wall corrugated pipe machine, highlighting the technology behind its components and the advantages of our machines for producing durable, efficient drainage pipes.
Modern infrastructure projects demand materials that are not only strong but also cost-effective and easy to handle. Drainage systems, especially those used for storm-water management, require pipes that withstand heavy loads such as soil pressure, vehicle traffic, and environmental stress. At the same time, these pipes need to be lightweight to reduce transportation and installation costs.
PVC double-wall corrugated pipes have emerged as the preferred solution because they combine excellent mechanical strength with reduced weight. The double-wall design—with a structured outer wall providing stiffness and a smooth inner wall ensuring efficient fluid flow—makes these pipes highly suitable for various drainage applications, from municipal storm-water systems to agricultural irrigation and industrial waste management.
Our PVC double wall corrugated pipe making machines are engineered to meet these demands by producing pipes that satisfy stringent standards for strength, durability, and flow efficiency, supporting the growing infrastructure needs worldwide.
With urbanization accelerating, managing storm-water runoff has become a critical environmental and engineering challenge. Cities are investing heavily in drainage systems that can efficiently handle heavy rainfall and prevent flooding. PVC double-wall corrugated pipes have become a core component in these systems due to their superior strength-to-weight ratio and corrosion resistance.
The infrastructure trend favors pipes that require less maintenance and have a longer service life. Because double-wall corrugated pipes are lightweight, they allow for faster installation, minimizing labor costs and project delays. Moreover, their corrosion resistance ensures longevity in aggressive soil conditions, making them ideal for both urban and rural drainage applications.
Zhangjiagang Lvima Technology Co., Ltd’s machines enable manufacturers to produce these high-quality pipes efficiently and reliably, supporting large-scale infrastructure projects globally.
Compared to traditional solid-wall PVC pipes, double-wall corrugated pipes offer distinct advantages. The outer corrugated layer acts as a reinforcement rib structure that significantly improves ring stiffness, allowing pipes to resist deformation under heavy loads. Meanwhile, the inner smooth wall provides minimal hydraulic resistance, ensuring efficient flow of fluids.
This structural efficiency means that double-wall pipes require less raw material to achieve the same or better mechanical performance, reducing material costs and environmental impact. Additionally, the improved stiffness extends the pipe's lifespan, reducing maintenance and replacement costs over time.
Our PVC double wall corrugated pipe machines are designed to manufacture pipes that capitalize on these benefits, producing products that meet or exceed international standards for drainage pipe performance.
At the heart of the PVC double-wall corrugated pipe machine lies the twin-screw extrusion unit. Unlike single-screw extruders, the twin-screw system offers superior mixing and melting capabilities, essential for handling the complex formulations of PVC compounds.
Lvima’s PVC pipe making machines are equipped with conical twin screws made from bimetallic materials, which are nitrogen treated to improve wear resistance and prevent corrosion caused by PVC's chemical nature. This bimetallic construction significantly extends screw life and ensures consistent melt quality.
The counter-rotating design of the twin screws promotes thorough mixing and homogenization of the PVC melt. This process eliminates material inconsistencies and guarantees uniform pipe wall thickness and mechanical properties—critical for achieving high-quality finished products with excellent structural integrity.
The corrugator block system is responsible for shaping the pipe’s characteristic corrugated outer wall. Precision and stability in this system directly affect pipe quality, stiffness, and dimensional accuracy.
Lvima’s machines feature a closed-loop water cooling system that tightly controls the temperature of the molds during corrugation. This system prevents thermal deformation of the molds, ensuring each pipe section maintains consistent outer dimensions and surface quality.
In addition, quick-change corrugation modules allow manufacturers to easily switch pipe outer diameters to meet different project requirements. This modular approach minimizes downtime and increases production flexibility, making it easier to respond to market demands without costly machine overhauls.
Vacuum forming and sizing technology plays a crucial role in defining the pipe’s precise corrugated profile. Our machines utilize negative pressure control within the vacuum chamber to ensure sharp and well-defined crests and troughs on the pipe's outer wall.
This sharp corrugation is essential for maximizing the pipe’s ring stiffness, directly influencing its load-bearing capacity. Following vacuum forming, the pipe undergoes dual-channel air cooling, which rapidly locks the pipe’s shape and prevents any deformation caused by residual heat.
This process guarantees pipes with consistent profiles and superior mechanical performance, ready to meet the challenges of demanding drainage applications.
The final manufacturing step in pipe production involves the online socketing and cutting system. Precision in this step is crucial for producing pipes that are easy to install and provide leak-proof joints.
Lvima’s PVC double-wall corrugated pipe machines incorporate servo-indexing systems that ensure accurate positioning during socket formation, producing bell-mouth sockets with high dimensional precision. This precision facilitates quick and reliable pipe connections in the field.
Depending on production needs, manufacturers can choose between flying knife cutters, which operate continuously and are ideal for high-speed production, and planetary cutters, which provide superior cut quality at moderate speeds. This flexibility allows users to tailor production lines to their specific product specifications and output requirements.
Zhangjiagang Lvima Technology Co., Ltd’s plastic pipe machines are engineered with a focus on delivering long-term value. The combination of reduced weight per meter and maintained ring stiffness lowers material costs and simplifies logistics.
Our machines also embrace total productive maintenance (TPM) principles, which minimize downtime and optimize service intervals. This reliability reduces the total cost of ownership for pipe manufacturers and ultimately benefits end-users by providing pipes with extended service lives and lower lifetime costs.
Whether producing PVC pipe making machines, HDPE pipe making machines, or specialized double-wall corrugated pipe machines, Lvima ensures that each product supports sustainable and efficient pipe manufacturing.
