Revision pieces
Access points into the pipe system for installation in manhole structures
The base bodies of the inspection openings are made of homogeneously extruded hollow bar. Different versions are available to suit the pressure requirements in the pipe system. The inspection openings are rectangular in shape. The lids of the inspection opening are shaped to be pig-friendly on the inside so that the pig does not float up during cleaning and the pigging process can be carried out without interruption, saving time and money.

PE100 inspection piece
General preliminary remarks
The molded parts to be offered must be made of material in accordance with the PE100+ Association and comply with DIN EN 12201 with regard to dimensions, tolerances and quality requirements. Proof of production on the basis of a quality assurance system in accordance with DIN EN ISO 9001 must be provided. A certificate in accordance with DIN EN 10204 must be provided by the manufacturer for all molded parts.
The body of the molded part must be made from a single piece of homogeneous semi-finished product in order to ensure the required reinforcement and thus high stability of the molded part. Semi-finished products made from winding rod or other subsequently applied reinforcements are not permitted.
The inspection piece must be made of PE100. It must be designed to meet the requirements of the pressure class and consist of the housing with a rectangular cover for the pig guide and external reinforcements. All screws as well as the flange components and any reinforcing ribs of the cover must be supplied in a hot-dip galvanized version. The seal must be made of media-resistant material.
The pipe connections must be designed as spigot ends in a sufficiently long form for HE butt welding or HW welding corresponding to the nominal width of the pipe. The inner beads of the HE butt weld joint must be removed.
An optional flushing connection can be provided on the body or in the lid. In addition, the inspection piece can be fitted with a support as specified. Alternatively, the cover can also be designed in a round version.
The pipe connections can optionally be fitted with flange connections to match the shut-off valve to be used. The flanges used must comply with the selected pressure rating and be made either of steel with appropriate corrosion protection or of corrosion-free, fiber-reinforced plastic.
