Mô tả
| A reducing tee is a pipe fitting used to branch a pipeline while changing pipe size, featuring two outlets of the same diameter and one larger outlet. It enables flexible pipeline connections while maintaining proper flow capacity and leak-tight performance during operation. Cấu tạo và phân loại: – Structure: Consists of an upper housing (with branch outlet), a lower (clamp saddle), and a specially designed rubber gasket that seals around the drilled opening on the main pipe. – Two common types: + Threaded mechanical tee: The branch outlet features female threads, used for installing sprinkler heads or measuring devices. + Grooved mechanical tee: The branch outlet is grooved, used for connecting to pipes or other grooved fittings. Technical specifications: – Brand: Penguin – Origin: Malaysia (or as per CO/CQ) – Material: Ductile Iron ASTMA536 – Connection type: Flanged / threaded (depending on model) – Configuration: 2 equal ends + 1 larger outlet – Connection standards: BS / JIS / DIN – Working pressure: PN10 / PN16 – Working temperature: ≤ 80°C – Sealing Gasket: C-shaped EPDM rubber gasket – Sizes: DN50×DN80, DN80×DN100, DN100×DN150 (or as required) – Applicable standards: ISO 17885, ISO 3458, ISO 3459, ISO 3501, ISO 3503, ISO 7 chịu áp lực PN16 – Suitable for PE pipes SDR9–SDR17, black color Key Features: – Enlarged branch design increases flow capacity at the main branch – Robust structure with good pressure resistance – Precision machining ensures excellent sealing performance – Easy installation, suitable for various piping systems Benefits: – Saves Time and Costs: Instead of cutting the pipe and installing a standard tee fitting (which requires three joints), you only need to drill a hole on the main pipe and install the mechanical tee (requiring just one branch connection). – Flexibility for Pipe Size Changes: It can be installed at any position on an existing pipeline, making it extremely useful for renovations or adding new fire sprinkler heads. – High Sealing Performance: The rubber gasket is tightly compressed by the bolt tightening force, ensuring leak-free operation even when system pressure fluctuates. – High durability and long service life while ensuring stable flow performance. – Minimizes leakage at branch connections – Compatible with multiple flange/thread standards Disadvantages: – Requires more installation space compared to equal tees – Weight increases with larger DN sizes – Correct installation orientation is required to ensure optimal flow – Requires specialized drilling equipment: A core drilling machine must be used to create a precise hole on the main pipe. The drilled hole diameter must comply with Penguin manufacturer specifications. – Surface Preparation: After drilling, the hole edges must be smoothed and metal shavings removed to ensure the rubber gasket seals properly and to prevent gasket damage. – Gasket Inspection: Ensure that the gasket is properly positioned at the center of the hole before tightening the bolts. Applications – Fire Protection Systems: Installation of sprinkler heads on the main pipeline. – Water Supply Systems: Creating branch connections for domestic water lines or installing water meters and pressure sensors. – Water Supply Systems: Creating branch connections for domestic water lines or installing water meters and pressure sensors. |
