The RKLF type corrugated pipe is a casing pipe designed for mechanical protection and protection against moisture of cables in concealed electrical installations. Thanks to the appropriate cross-section, the pipe is very flexible, while maintaining good mechanical resistance (up to 320N). The shape of the pipe allows it to be used in hard-to-reach places while ensuring the possibility of replacing the cable. In addition, the RKLF pipe is characterized by high tensile strength and ensures easy cable entry over longer distances. RKLF type pipes are made of modified polypropylene, which, being a combustible material, has such features as high tensile strength, high impact strength and temperature resistance.
