Electrofusion tee 90ST.-set with electrofusion coupling and electrofusion reducer d90x90 PE100, SDR11, PN10 gas/PN16 water 753201613

Kit for creating branches in gas and water installations

This complete kit is designed for making safe and leak-tight branches in polyethylene (PE) pipelines. It consists of a 90 mm electrofusion tee, an electrofusion coupling, and an electrofusion reducer, eliminating the need to purchase individual components separately. The entire set is made from PE-100 material in the SDR11 variant, ensuring resistance to high pressures and durability under demanding operating conditions.

Thanks to the use of electrofusion welding technology, installation is fast and repeatable, achieving a fully leak-tight joint without the need for additional gaskets or flanges. The kit is intended for installations transporting gas (up to 10 bar) and water (up to 16 bar), making it a universal solution for distribution networks. All components have an identical outer diameter of 90 mm, simplifying pipeline route planning.

Key Features and Applications

The kit has been designed to facilitate the installer's work while ensuring high reliability for the end user. PE-100 material is characterized by high resistance to corrosion and chemical aggressiveness of the environment, which is crucial during long-term contact with water or gas.

• Comprehensive solution: The kit includes a 90° tee, an electrofusion coupling, and an electrofusion reducer – all in one package, ready for immediate installation.
• Versatile application: Designed for gas systems (PN10) and water supply systems (PN16), allowing its use in various types of infrastructure networks.
• Material durability: Construction from PE-100 polyethylene ensures long service life of the installation and resistance to mechanical damage during excavation or pipe laying.
• Easy installation: Electrofusion welding technology enables quick connection of components without the need for complex mechanical tools or thermal welding methods requiring large maneuvering space.

It is worth noting that all parts are made of high-density polyethylene PE-100 with a dimension ratio SDR 11. This construction allows safe operation at a working pressure of PN 16 for water and PN 10 for gas at an ambient temperature up to 20°C. All three connections have an outer diameter of 90 mm, facilitating integration with existing pipes of the same type.

Construction and Operating Conditions

The kit components have a raw surface at the connection points, meaning they require appropriate cleaning and scraping according to the manufacturer's procedures before starting the welding process. The absence of gaskets or drain valves makes the construction simple and less prone to failures resulting from mechanical leaks. The tee does not have directional flow stiffening, allowing free adaptation to the local pipeline geometry during installation.

The maximum allowable working pressure is 16 bar for water at a temperature of 20°C. In the case of use in gas installations, this limit drops to 10 bar due to the specific nature of the medium and safety requirements. Thanks to this, the kit is ideal both for new construction projects and for modernization of existing transmission networks, where connection reliability is a priority.
