Plastic secondary containment piping systems

Secondary containment piping systems in plastic are a safe and cost-effective solution for the controlled conveyance of aggressive media. The inner pipe can be monitored with a leak warning system and should the medium leak from the pipe, it will be contained in the outer protective pipe until the damage can be located and attended to. Such systems provide an increased level of protection for persons, equipment and the environment, in addition to fulfilling the relevant legal requirements.
Environmental protection and operational safety are of increasing importance in today's world. This is especially true for the conveyance of liquid and gaseous media that are hazardous to persons, water and the environment in general. Piping systems made of thermoplastics are increasingly used for this purpose. They are replacing conventional pipe materials such as steel, cast iron, concrete, stoneware, ceramic, and even FRP. Secondary containment systems consist of an outer protective pipe, into which the medium-conveying inner pipe is integrated. The space in between is used to detect leaks or to stabilize the temperature of the medium in the inner pipe with a liquid. Due to their good chemical and mechanical resistance, plastics are ideally suited for the construction of secondary containment piping systems.
