Afløbsstykker

Afløbsstykker are a category of drainage components used in Danish plumbing and civil engineering. They are fittings or short pipe segments that form part of a drainage system and are intended to carry wastewater or stormwater away from buildings or surfaces to a sewer, storm drain, or watercourse. Afløbsstykker can take various forms, including straight pipe pieces, elbows, tees, couplings, adapters, and reducers, and are designed to connect with other elements such as downpipes, catch basins, basins, and manholes. They are manufactured in materials such as PVC (uPVC), concrete, and cast iron, with material choice influenced by local codes, environmental conditions, load expectations, and compatibility with other pipes in the network.

Design and installation considerations: Selection should match the system diameter and material, and joints must be sealed with appropriate gaskets or jointing methods. Proper slope and alignment are essential to promote gravity-driven flow. In buried installations, frost resistance, soil loading, backfill, and protection against damage are important. Venting may be required to prevent siphonage in fixtures. Connections should be clean and dry before assembly, and joints should be tested for leaks after installation. Compliance with local standards and building codes is expected, and accessibility for maintenance is advantageous.
