External PVC drainage pipe 160X4.7X1000 SN8 Class S SOLID, with extended socket and K-U21 LOCK type gasket 032344L100

PVC Drainage Pipe for External Systems

External drainage pipe made of polyvinyl chloride (PVC-U) is a key element in the construction of non-pressure sewage and drainage systems. Designed for laying in the ground, both under roadways and in open areas, it performs perfectly in civil engineering systems and as a protective casing for other conduits. Its strength and resistance to loads allow it to be used in areas exposed to vehicle traffic and in areas with variable geological conditions.

The pipe with a diameter of 160 mm and a stiffness class of SN8 is characterized by high resistance to mechanical and chemical damage. The orange color makes it easier to identify the pipe during installation and maintenance work. Equipped with an extended socket with a locked seal of the LOCK type (K-U21), it ensures tight and durable connections, minimizing the risk of leaks and infiltration. This solution is particularly important in mining areas, where there is a risk of ground deformation.

Construction and installation

PVC-U pipes are characterized by a low weight compared to traditional materials such as cast iron or stone, which significantly facilitates transport and installation. The smooth inner surface minimizes flow resistance, and the precise dimensions guarantee easy connection with other elements of the sewage system. The extended socket with a locking seal ensures quick and reliable installation, eliminating the need for additional sealants. This makes the installation faster and less labor-intensive – which will be appreciated by both professional installers and people independently implementing construction projects.

Application and advantages

These pipes are widely used in:

• Construction of sanitary, rainwater and industrial sewage networks.
• Drainage of road and railway areas.
• Protection for power and telecommunication cables.
• Culverts under roads and railway embankments.
• Bridge structures – as drainage elements.

Benefits of use:

• Durability: PVC-U material is resistant to corrosion, chemicals and weather conditions, guaranteeing a long service life of the system.
• Tightness: The LOCK-type locking seal ensures reliable connections without the risk of leaks.
• Easy installation: The low weight of the pipes and the simple connection system speed up installation work.
• Mechanical resistance: Stiffness class SN8 provides adequate resistance to external loads.
• Versatility: Can be used in various ground conditions, including mining areas.
• Compliance with standards: The pipes meet the requirements of PN-EN 1401-1 and have a Technical Approval ITB AT-15-7558/2016 confirming their high quality and safety of use.
