PVC-U Pipes, PVC-U Fittings, and PVC-U Valves - Reliable Solutions for Piping Systems
PVC-U pipes are ideal for connecting and distributing flow rates in piping systems. Depending on the nominal size, they are designed for specific operating pressures, which also depend on temperature and media concentration. The different pressure ratings of PVC-U pipes can be effectively bonded using Tangit adhesive from the renowned company Henkel. When bonding PVC-U pipes, it is important to follow the basics of the DVS bonding process. Bonding PVC-U pipes requires expertise in handling plastic piping systems. The bonding surface is determined by the Z-dimension in the PVC-U fitting.
PVC-U fittings, like PVC-U pipes, are used for connecting and distributing flow rates in piping systems. At Kwerk, we differentiate between PVC-U solvent-weld fittings. These fittings have a solvent socket or a solvent spigot at one end. PVC-U transition fittings have a solvent socket or a solvent spigot on one side and an internal or external thread on the other side. PVC-U threaded fittings have internal or external threads on both ends. The PVC-U ball valve for water technology serves as the basic model for further variations of PVC-U ball valves. At Kwerk, you will find a wide range of PVC-U valves, including PVC-U diaphragm valves, PVC-U check valves, PVC-U ball check valves, PVC-U strainers, PVC-U angle seat valves, PVC-U laboratory valves, PVC-U shut-off valves, and PVC-U intermediate flanged valves, all made of high-quality PVC-U.
We place great emphasis on brand quality for our PVC pipes, fittings, valves, and accessories. Our products cannot be compared to cheap suppliers from other regions of the world. The certifications speak for themselves and make us a reliable partner in the industrial, chemical, and process engineering sectors. We would be happy to provide you with a free quote upon request.

PE Piping Systems for Reliable Drinking Water Supply and Wastewater Technology - MADE IN GERMANY
PE pipes have become indispensable in the field of drinking water supply and wastewater technology. Especially in underground pipeline construction, particularly in Northern Germany with its sandy soil conditions, PE pipes are highly popular. The material PE 100 is known for its excellent resistance to a wide range of acids and alkalis. While polyethylene is conditionally resistant to hydrocarbons, chlorine, and ozone, the chemical resistance depends on various factors such as operating temperature, operating pressure, and other influences.
Thanks to continuous development, gas pipelines are now successfully installed using PE pipes. To prevent damage to the pipe surface, the PE pipe is bedded in sand according to common laying guidelines. Pipe and raw material manufacturers are constantly working on improving the material qualities, resulting in a variety of PE pipes available for different applications. PE has now replaced the material PVC-U in plant engineering, such as after the Düsseldorf airport fire.
Due to their technological properties, PE pipes and PE fittings are also highly popular in plant engineering. Different types of PE fittings are used for various applications and processes. In underground pipeline construction, fittings with long welding necks are primarily used to connect PE fittings with heating coil fusion sockets. The butt fusion process is also applied to these long fittings. Another widely used technique is the connection of PE pipes with clamp connectors made of PP, which are approved for drinking water supply and provide additional safety. In plant engineering and traditional pipeline construction, PE fittings with short design are used, which are 100% installed and welded using the butt fusion process.
Kwerk.de offers a wide range of tools, flanges, and welding systems for the secure connection of PE piping systems. We place great importance on delivery and quality MADE IN GERMANY. Our products and associated manufacturers also provide extensive technical support. Feel free to contact us with any questions. We are here to assist you.
PVDF - The Reliable Material for Demanding Applications in Chemical and Process Engineering
PVDF is a material with exceptional resistance to acids, organic liquids, and UV radiation. Its main application is in chemical and process engineering. Thanks to its high purity, PVDF is also used in ultra-pure water and deionized water systems for the semiconductor and photovoltaic industries. PVDF pipes, fittings, and valves are made from high-quality PVDF SOLEF® resins that offer excellent properties for industrial applications. To make your search easier, we have organized our valves in the navigation menu. Here you will find the PVDF ball valve, PVDF diaphragm valve, PVDF check valve, and PVDF butterfly valve.
PVDF is a thermoplastic construction material with a fluorine content of approximately 59%. PVDF is formed through the polymerization of the monomer vinyl fluoride, resulting in a plastic with outstanding mechanical, physical, and chemical properties. It can be used in a temperature range up to 140°C. The PVDF resin from SOLEF® is a granulate that is free from additional additives such as thermal stabilizers, fillers, and processing aids. By avoiding such additives commonly used in other thermoplastic materials, the excellent properties of PVDF, such as its chemical resistance, are retained even after processing. This exceptional versatility in terms of pressure, temperature, and chemical environments makes PVDF the preferred material in the chemical and pharmaceutical industry, automotive industry, pulp and paper industry, and many other sectors.
