Connection PPR <\/a>\u00d832\u00d71 is equipped with two connection ends for welding and is intended for joining polypropylene pipes and other components of engineering systems. For convenience, threaded connections are also used, as well as for welding pipes of different diameters. PPR fitting \u00d832\u00d71 can be used in construction for organizing heating, water supply, cooling systems, based on heat pump<\/a>.<\/p>\n PPR \u00d832\u00d71 fitting is used to connect pipes, different technologies are used. Let's analyze the most common ones:<\/p>\n It is a simple and safe method. The connection of the PPR Connector \u00d832\u00d71 is made by internal and\/or external threading applied to the ends. The threaded fittings of the PPR Connector \u00d832\u00d71 maintain the internal diameter of the pipes, ensuring good hydrostatics.<\/p>\n They are used to make watertight connections. The gallery clamps the pipes onto the insert profile made of brass, PVDF or PPSU. This method ensures durability.<\/p>\n This method involves using a fitting, a cut ring, and a screw-on nut. When the nut is tightened, the ring compresses the pipe, creating a watertight connection.<\/p>\n It allows welding of pipes at the molecular level. The connections are leak-proof and resistant to high loads, but require certain skills.<\/p>\n Homogeneous materials are heated to the required temperature and bonded together. This method ensures reliability and strength.<\/p>\n It utilizes the properties of the material, allowing the pipe to return to its original shape after expansion.<\/p>\n In systems with compression connections, the cross-section can decrease by 25-37%. For example, for a pipe with a diameter of 16 mm and a wall thickness of 2 mm, the inner diameter decreases by 4-6 mm. In systems with PP-R tees, such losses do not occur. This makes them ideal for modern engineering solutions.<\/p>\n Tees are ideal for use in central heating systems, where reliable pipe connections are required. In industrial conditions, they are used for compressed air supply, demonstrating the versatility of these fittings. For safe installation of tees, the edges of the pipe must be prepared and the surface must be clean. A welding machine with a nozzle of the appropriate diameter is used, the elements are heated to 260\u00b0C and the components are joined in a few seconds, ensuring correct positioning. Unlike metal fittings, polypropylene tees are not exposed to corrosion and retain their properties even after decades of use. They are much lighter, which facilitates installation and transportation. Polypropylene fittings are environmentally friendly: they do not emit toxic substances during operation, which makes them safe for drinking water supply systems. PP-R tees have been widely used in the construction of modern residential complexes, demonstrating their reliability and durability in heating and water supply systems.<\/p>\nOPERATING CONDITIONS:<\/h3>\n
