In the DIN 4925 standard published by the German Standardization Institute (DIN), the requirements for filtered and closed, circular cross-section seamless pipes produced from hard polyvinylchloride and used in deep wells, and the spurs and reductions used in laying these pipes are explained. Part one of this standard describes the requirements and dimensions for PVC-U plastic well screens and casings and threaded connections with nominal diameters DN 35 to DN 100. Pipes serve to install pipe wells for obtaining groundwater.

PVC-U is an unplasticized version of PVC made from polymer. PVC stands for polyvinyl chloride, while U stands for unplasticized. Shortly defined as PVC-U, this material has become a popular material for windows and doors due to its resistance to weathering, absence of rot, flaking, peeling, rusting and deterioration.
The second part of this standard describes the requirements and dimensions for trapezoidal threaded pipes with nominal diameters from DN 100 to DN 200. The third part of this standard describes the requirements and dimensions for trapezoidal threaded pipes with nominal diameters from DN 250 to DN 400.
The material, known as unplasticized polyvinyl chloride, is a low-maintenance building material that is often also used as a substitute for painted wood for window frames and sills when installing double glazing in new buildings or to replace old single-pane windows. This material has almost completely replaced the use of cast iron for plumbing and drainage, which is used for waste pipes, drain pipes, gutters and downpipes.
PVC-U is a cheaper and more durable alternative to expensive wood lumber and aluminum. Its surprising strength comes from the fact that it is produced using vinyl polymer bonded to chlorine atoms, so this material works well with steel.
Among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, our organization, with its trained and expert staff and advanced technological equipment, test for well grids and casings produced from unplasticized polyvinylchloride for tube wells within the scope of DIN 4925 (TS 11794) standard. also provides services.
