Sewer and drainage pipes

Extrusion lines for sewer networks and wastewater management systems

The production of sewer and drainage pipes requires extrusion lines designed to handle high output rates, large diameters, and materials with high mechanical strength. In the construction and infrastructure sectors, these pipes are used to convey wastewater and stormwater and must ensure durability, dimensional stability, and continuous operation. Bausano develops extrusion solutions that support sewer pipe manufacturers with reliable, high-performance systems engineered to deliver long-term value.

Sewerage pipes applications with Bausano Extrusion Lines

In the construction and infrastructure sectors, sewer and drainage pipes are used for the collection and transport of wastewater and rainwater, both inside buildings and across external networks. These applications require pipes capable of withstanding mechanical loads, chemical stress, and demanding installation conditions, including deep underground installation and areas exposed to heavy traffic.
The plastic materials most commonly used for sewer pipes include PVC-U, PP, and HDPE, selected according to the required stiffness, impact resistance, and long-term durability. The quality of the finished pipe depends on extrusion process stability and the precise control of wall thickness, ovality, and structural performance.

Materials, diameters, and production configurations

Sewer pipes are manufactured in a wide range of diameters, wall thicknesses, and structural configurations. Their production therefore requires flexible, robust extrusion lines capable of adapting to different technical requirements.

The most commonly used materials are:

PVC-U, for rigid solid-wall pipes widely used in construction and infrastructure.
PP, for drainage systems requiring higher thermal resistance.
HDPE, mainly used for large-diameter and underground applications thanks to its high toughness.

Typical diameters range from small pipes for residential drainage systems to large-diameter pipes for municipal sewer networks and infrastructure projects.

Bausano extrusion lines for sewer and drainage pipes

Bausano designs and manufactures complete extrusion lines for PVC-U, PP, and HDPE sewer and drainage pipes, configured to cover a wide range of diameters and applications.
Bausano solutions are engineered to maintain stable processing even under demanding production conditions, where accurate thermal control and uniform material plasticization are essential. The lines can integrate advanced calibration and cooling systems, as well as socketing machines for pipes with integrated joints, a widely used solution in modern sewer networks.

Productivity, large diameters, and market comparison

In the sewer pipe extrusion market, competitive performance depends on actual output, large-diameter processing capability, and production continuity. Bausano extrusion lines are designed to manufacture pipes with diameters of up to 1,600 mm, a key requirement for major infrastructure applications.
Typical productivity ranges for rigid PVC pipes vary according to pipe diameter:

Small pipes (16–63 mm): output of approximately 150–600 kg/h, with line speeds of 3–20 m/min.
Medium pipes (75–200 mm): output of 300–1,200 kg/h, with line speeds of 1–6 m/min.
Large pipes (250–630 mm and above): output of 800–2,000+ kg/h, with line speeds of 0.2–2 m/min.

In these applications, throughput is primarily determined by the extruder, while line speed depends on cooling capacity, calibration performance, and pipe dimensional stability.
Bausano designs every line around these production constraints, delivering balanced systems that maximise output without compromising finished-pipe quality. This approach differentiates Bausano from standard market solutions, which are often less effective in large-diameter and high-output production.
