| The male thread tee is a T-shaped pipe fitting featuring two PPR fusion sockets and one metal male threaded outlet. It is used to branch pipelines while connecting to internally threaded devices such as valves, water meters, metal elbows, and other threaded fittings. Technical specifications: – Material: + Fitting body: PP + Male threaded insert: Nickel-plated brass or stainless steel (SS304) – Size range: DN20 – DN110 + Male thread sizes: ½”, ¾”, 1″, 1¼”, 1½”, 2″ + Configuration: 2 equal fusion ends + 1 BSPT male thread (ISO 7/1) – Working pressure: PN16, PN20 – Working temperature: 0 – 95°C – Connection type: + Pipe ends: PPR heat fusion welding + Male thread end: threaded connection with PTFE tape / thread sealant – Standards: ISO 17885, ISO 3458, ISO 3459, ISO 3501, ISO 3503, ISO 7 – Sealing gasket: C-shaped EDPM rubber surrounding the drilled hole. Đặc điểm cấu tạo: – Tee body: Consists of two separate ductile iron halves that fully clamp around the main pipe: One half features a raised outlet with machined male threads, while the other acts as a retaining clamp. – Sealing mechanism: A specialized rubber gasket is placed at the drilled hole position on the main pipe. When the bolts are tightened, the gasket is compressed against the pipe surface, creating a completely leak-tight seal. – High-strength bolts: Supplied with a set of galvanized bolts and nuts with excellent load-bearing capacity. ensuring the tee is securely fastened to the main pipe. Key features: – Flexible combination of PPR fusion joints and metal threaded connection – Metal threaded insert provides excellent resistance to heat and pressure without deformation – Completely leak-tight when installed correctly – Corrosion-resistant, non-toxic, suitable for potable water systems – Smooth internal surface reduces flow friction Benefits: – Quick installation and easy connection to threaded equipment – Heat resistant up to 95°C – Flexibility: Allows branch connections to be created at any position on the pipeline without the need to dismantle or cut the pipe. – High durability with service life of 25–50 years – Lightweight and simple to install – Stable performance with excellent leak resistance – Cost-saving: Significantly reduces labor costs and installation time compared to installing a reducing grooved tee assembly (which requires up to three couplings) Disadvantages: – Higher cost compared to standard fusion tees – Threaded end requires PTFE tape or thread sealant to prevent leakage – Not reusable once PPR fusion welding has been completed – Tightening force: The bolts must be tightened evenly on both sides so that the tee fits uniformly onto the main pipe, preventing gasket misalignment. – Cleaning: Iron filings must be removed and the edges of the drilled hole must be smoothed to ensure the rubber gasket adheres evenly and does not tear when water pressure increases. Applications – Fire protection system: Used to install outlet points, water supply branches for hose reels, or connections for flexible fire-fighting hoses. – Water supply system: Used to branch off pipelines for measuring devices (pressure gauges) or air release valves. – Compressed air system: Used to create air outlet points at positions along the main pipeline within the factory. |
