DUOFLEX, DUOHARD protective pipes

Material            

• DUOHARD - outer and inner walls are made of PE-HD.
• DUOFLEX - outer walls are made of PE-HD, inner wall are made of PE-LD (for diameters of 40, 50 and 63 mm) and of PE-HD (for diameters from 75 mm).

Pipe design

• outer wall - corrugated for higher mechanical strength of the pip.
• inner wall - smooth for easy cable installation. Slight corrugation provides for excellent flexibility, does not reduce passage capacity through the pipe in bends and maintains high strength.

Colour design

• outer wall - red, black or blue (standard colours)
• inner wall - black (standard)

Heat resistance

• installation temperature: dandling PE-HD pipes within of -5ºC to + 50ºC
• operation temperature: of -40ºC to +70ºC

Pipe connection

• the pipes are connected using slide-on couplings
• pipes of both production lengths are delivered with a coupling on one end

Drawing element and cable introduction

• DUOFLEX protective pipes in coils have pre-installed drawing elements (PV-PAD, thickness 1,2 mm or PP string 12 500 dtex)
• cables must be introduced into DUOFLEX and DUOHARD pipes via drawing (blowing-in not possible). Smooth inner walls provide for easy cable introduction into the pipe.

Storage

• in horizontal position, maximum storage height 2 m
• max storage time up to 3 months
• it is not recommended to store in direct sunlight (to DN 160 does not contain UV stabilizer)

Pipe laying

• in order to maintain maximum mechanical strength of DUOFLEX and DUOHARD protective pipes observe installation instructions issued by MATEICIUC a.s.
