CORRUGATED DRAINAGE PIPES

Features of corrugated double-layer pipes made of PE (polyethylene)
The outer wall of the pipe is a corrugation, due to which the necessary ring stiffness is created. Execution SN4, SN6, SN8, SN10, SN16 is possible. The color of the outer wall is black.
The inner wall is white and has a smooth, even surface. Due to this, sewage flows do not linger inside the pipe, which prevents deposits and overgrowth.
Welded socket. All pipes are produced in 6m lengths. Each segment is equipped with a welded socket. This greatly simplifies installation.
Advantages of corrugated two-layer sewer pipe FD
Environmental friendliness. The polyethylene from which the pipes are made does not emit harmful substances. Therefore, corrugated sewer pipes can be used at facilities with high environmental safety requirements.
High resistance to mechanical abrasion
High chemical resistance
Tightness of connections
Ease of transportation. Sections of 6 meters are more convenient for transportation than 12 meter rods.
Ease of installation. Each section of the pipe is equipped with a socket. A coupling is not needed to connect two segments.
Connection of corrugated sewer pipes
The connection of corrugated two-layer pipes FD is possible in several ways
With a bell and a rubber sealing ring. The ring is inserted into the cavity of the corrugation. After that, the bell is pushed onto the ring.
With heat shrink sleeves.
With the help of electrowelded couplings. This method requires special couplings with embedded electric heaters and a special apparatus for welding.
