Reducing Tee

Product Overview

Sikerui UPVC Reducing Tee is a high-performance pipe fitting engineered from unplasticized polyvinyl chloride (UPVC), designed to create a branch connection from a main pipeline while reducing the flow diameter. This specialized tee fitting is essential for complex piping networks that require efficient flow distribution between pipes of different sizes. Renowned for its exceptional durability, corrosion resistance, and cost-effectiveness, it is designed to meet rigorous international standards such as ISO 4422, DIN 8063, and GB/T 10002.2 . It excels in demanding applications including water supply, chemical processing, irrigation, and drainage systems. With a service life exceeding 50 years, it combines lightweight simplicity with robust performance, offering a sustainable and reliable alternative to traditional metal fittings . The smooth interior surface ensures minimal flow disruption and pressure loss, while its resistance to chemicals, UV radiation, and abrasion guarantees long-term reliability .

Features of UPVC Reducing Tee

• Superior Corrosion & Chemical Resistance​ – Highly resistant to acids, alkalis, and a wide range of corrosive chemicals, making it ideal for industrial effluent, chemical transport, and agricultural applications involving fertilizers .
• Optimized Flow with Reduction Design​ – Features a smooth interior surface and a precision reduction in the branch outlet, which minimizes friction loss, prevents sediment buildup, and ensures efficient flow transition between different pipe diameters .
• Lightweight and Easy Installation​ – Significantly lighter than metal tees, reducing transportation and labor costs. Allows for quick and secure connections via solvent cement welding or threaded ends, simplifying the installation process .
• Robust Construction & Long Service Life​ – Designed to withstand pressure ratings of PN10 and PN16 (1.0-1.6 MPa) and temperatures ranging from 0°C to 60°C (with some SCH80 ratings up to 65°C), ensuring a service life of over 50 years .
• Eco-Friendly and Non-Toxic​ – Complies with international potable water safety standards (e.g., NSF/ANSI, ISO 4422), ensuring safe use in drinking water systems without affecting water quality .
• Versatile Connection Types​ – Available in various types including solvent weld, threaded (male/female), and rubber ring (gasketed) ends to suit different installation requirements and pipeline designs .

Typical Uses of UPVC Reducing Tee

• Potable Water Distribution Systems: Used to branch off a smaller water supply line to a building or fixture from a larger main distribution pipe. Its non-toxic nature ensures the water remains safe and uncontaminated .
• Industrial Chemical Processing: Ideal for plants handling corrosive chemicals, acids, or alkalis due to its exceptional chemical resistance. Used to divert process streams to equipment with different inlet sizes .
• Agricultural Irrigation Networks: Effectively distributes water from a large main line to smaller feeder lines or drip irrigation systems. Its resistance to corrosion from fertilizers and insecticides makes it a durable choice for farming .
• Sewage and Drainage Systems: Employed in sewer and waste drainage networks to connect pipes of varying diameters, efficiently managing the flow of waste and corrosive gases in residential, commercial, and industrial settings .
• Mining and Ventilation Systems: Well-suited for draining corrosive liquids in mines and for ventilation ducts, as they are easy to install in hard-to-reach places and resist chemical degradation .
• Electrical Conduit Systems: Serves as a protective, non-conductive fitting for electrical and telecommunications cables, allowing for directional changes and size adaptations in conduit runs .
