Ventilation pipes. Storage tanks. Pressure piping.
Spiral pipes made of PE and PP have proven themselves over many years for tank and apparatus construction, as well as ventilation technology. FRANK spiral pipes are of high quality and offer the processor and the end customer a maximum of safety.
The FRANK spiral pipes are manufactured using the winding process in accordance with DIN 16961. Here, a homogeneous plasticized tape is wound in a spiral on an inner core (steel core) and connected to one another by overlapping. The fixed inner core ensures a constant inner diameter (DN) even with different wall thicknesses or loads. The wall thicknesses and gradations are designed and manufactured individually according to the operating conditions.
Spiral pipes are available in the thermoplastics PE 100, PE 100-RC, PP-R, PP-B and PP-H as well as in the special materials PE-el, PPs and PPs-el. The materials used are characterized by good processability and good resistance to a wide range of acids and alkalis, as well as other media.
Quality and external monitoring of our spiral pipes:
The high-quality standard is documented in the general building inspection approval of the German Institute for Building Technology. Furthermore, the following points are externally monitored by "Hessel Ingenieurtechnik":
