Non-Profil-Module Typ No / V

FOR MUTED WELDING

Channel rehabilitation of egg profile channels in the Lining process

Not only the excellent material properties of PE 80 and PE 100 characterize the material for renovation concepts, but also the possibility of flexible shaping and adaptability. It is therefore possible in addition to the conventional circular profiles and egg-profile shapes such as standardized and non-standard egg profiles, mouth and box as well as elevated and elongated circular cross-sections industrial manufacture.

The egg profile modules are manufactured individually and tested for material properties (modulus of elasticity), geometry, dimensional stability, dimensional stability and usability according to a defined plan and monitored in order to meet the required quality standard.

In accordance with the given installation conditions, the design of the wall thickness is determined after establishing a verifiable statics. The basis for the static verification of remediation measures for non-pressurized sewers and pipes in the lining method is the ATV-DVWK regulations "Bulletin ATV-M 127, Part 2".

The PE-egg profile modules are supplied with a smooth finish and are designed for butt welding. For the welding of the type Ei / V modules, a compact tube welding butt welding machine is available for rent. The welding unit consists of a fixed and a movable part, which is each provided with a double clamping device. The clamping elements are adapted to the profile geometry and are clamped hydraulically in the pipe. The modules are welded using a split heating mirror in accordance with DVS guideline 2207, part 1. The welding machine can be used for standardized and non-standardized egg profiles in the range b / h 500/750 to 1000/1500 (see information below) and for module lengths of 1.0 m - 2.5 m.

The egg profile modules can also be welded to any trench butt welding machine. The welding jaws are supplied by the manufacturer according to the egg profile dimensions.
