Tee GW 22x1/2x22 - thin-walled, cold-formed galvanized carbon steel PC4130G0220422

Application and Construction of a Tee for Water Installations

This component from the group of press-fit fittings is used to create branches in piping systems, connecting three sections of the system. In this case, we are dealing with a configuration where two arms feature press-fit sleeves with a diameter of 22 mm, while the third arm terminates with a tapered gas internal thread (BSPT) of nominal diameter 1/2 inch. Such construction is typical for locations where a branch must be led to a fitting or device requiring a threaded connection, e.g., a valve or pump, while maintaining the continuity of the steel pipeline.

The material of manufacture is carbon (alloyed) steel, which after surface treatment receives an electro-galvanized layer. This solution ensures corrosion resistance under standard operating conditions of water and heating installations. It is worth noting that the connections are intended exclusively for the pressing method – they do not require the use of gaskets in the traditional sense (as in threaded connections), since tightness is ensured by special sealing rings inside the press-fit sleeve. The maximum working pressure for this component is 16 bar at a temperature of 20°C, which meets the needs of most domestic and industrial heating or cold water systems.

Benefits for the Installer and End User

For a professional installing the system, the key factors are speed and repeatability of connections. The press-fit system eliminates the need to use fire (welding) or complicated threading tools on-site. Proper pressing is sufficient to achieve a tight connection within a few seconds. As a result, project completion time is significantly reduced, and the risk of human error decreases. For the end user, this means a durable installation that does not require periodic tightening or maintenance of threaded connections, which over time may loosen or corrode due to vibrations.

This component does not have a stop flange or additional drain valves or air vents – its function is purely mechanical: transferring flow and changing direction or splitting the water stream. The absence of certifications such as UL or FM suggests that the product is intended primarily for the European market for standard civil and commercial applications, rather than for specific explosion-hazardous zones or requiring rigorous American standards.

Installation Characteristics and Operating Conditions

When selecting this tee, it is worth considering the specifics of its connections: two sides are press-fit sleeves dedicated for pipes with a diameter of 22 mm, facilitating quick installation without additional gaskets, while the third side is a ready-made internal thread of 1/2 inch (BSPT/Rc type), ideal for directly screwing on fittings. The entire assembly is made of alloyed steel with an electro-galvanized coating, ensuring corrosion resistance in water and heating environments at a working pressure up to 16 bar at a temperature of 20°C.

Installation requires the use of a dedicated pressing tool – the process is clean and fast, generates no sparks, and does not require the application of assembly paste at the sleeves, which is a significant advantage during renovation work or in confined spaces. The product will perform well both in new water supply and central heating installations, as well as during modernization of existing steel galvanized piping systems, where a transition from the press-fit system to threaded connections or vice versa is necessary. One should only remember to carefully prepare the pipe ends before pressing and to match appropriate threaded components to the tapered arm.
