Pipe preparation The delivered rods or rolls – depending on material and dimension – need to be cut to size. A precise, warp-free 90° cut without roughed edges is the basic requirement for the further Continue reading Pressing technology for piping connections – Pipe preparation and processing, Leak testing
When pipes and fittings are connected during the installation of drinking water supply systems and when linking heating systems with one another, the pressing process is the most common method used. In the middle of Continue reading Pressing technology for piping connections – Basic Knowledge
Former: VPE = Vernetztes Polyethylen Today: PEX = Polyethylen crosslinked (X-linked) We distinguish between 4 different methods: PE-Xa = with peroxide (Engel, PAM, Fränkische, etc.) PE-Xb = with Silane (Dow Corning/Sioplas) PE-Xc = by electronic Continue reading PEX pipes
Polypropylene (PP) is a Polyolefin resin polymerized by using a Ziegler-Natta catalyst process. To produce granulate, PP is compounded after polymerization. During the compounding process, phenolic and phosphatic antioxidants and, mostly also, color pigments are Continue reading PP-R pipes
Current industry standards classify two different design types: M – Type: multi-layer metal pipe This type of pipe comprises all design types with a metal middle layer regardless if the middle layer is welded or Continue reading Multilayer pipes
