In previous article, I talked about types of press fitting systems for metal pipes . It differ in material from which it made - copper, stainless and carbon steel. The latter type is the most economical option. Although it has limited scope. This is due to some technical features. That's about it today and I will tell. Pict.1 Carbon steel fittings from Frabo (Italy) Material Elements of systems made of carbon steel. Depending on the application, factory and type of element, steel grade may be different. Fittings usually made of next steel grades: - 1.0225; - 1.0034; - 1.0038. Steel grades that are used to pipes producing: - 1.0215; - 1.0220; - 1.0031; - 1.0034. In the bulk of the products for heating systems, manufacturers use steel E195 (1.0034), for fire extinguishing systems (splinkers) - E220. The main differences are in the physical parameters of the material (pls see tab.1): Tabl.1 Characteristics of different steel grades A...
