Overview
The 110*75mm Bottleneck Tee is a specialized pipe fitting designed to connect three pipes, with two outlets of differing diameters (110mm and 75mm). It is widely used in industrial piping, drainage systems, and plumbing installations where flow redirection or branching is required between pipes of unequal sizes. This fitting is engineered to maintain structural integrity under pressure while accommodating the transition between pipe diameters. Its asymmetric design distinguishes it from standard equal-diameter tees, making it a critical component in systems requiring flow distribution or collection from pipes of different capacities.
Structure and Working Principle
The 110*75mm Bottleneck Tee features a T-shaped structure with one inlet (typically 110mm) and two outlets (110mm and 75mm). The internal geometry ensures smooth flow transition between the larger and smaller pipes, minimizing turbulence and pressure loss. Constructed from materials like PVC, HDPE, or stainless steel, the tee’s design includes reinforced joints to withstand mechanical stress. The working principle relies on diverting fluid or gas from the primary line (110mm) into a secondary line (75mm) while maintaining the main flow path. This is particularly useful in systems where partial flow diversion is needed without disrupting the primary pipeline.
Key Features
1. **Diameter Transition**: Seamlessly connects 110mm and 75mm pipes, eliminating the need for additional adapters. 2. **Material Versatility**: Available in corrosion-resistant materials suitable for water, chemicals, or gases. PVC and HDPE variants are common for drainage, while stainless steel is preferred for high-pressure industrial applications. 3. **Pressure Resistance**: Engineered to handle system pressures up to 10–16 bar (varies by material), with reinforced socket or butt-weld ends for secure connections.
Application Areas
1. **Industrial Piping**: Used in chemical plants, wastewater treatment, and manufacturing facilities to branch off smaller auxiliary lines. 2. **Drainage Systems**: Installed in municipal or building drainage networks to redirect flow from larger collectors to smaller branch pipes. 3. **Plumbing**: Facilitates water supply distribution in commercial buildings where pipe diameters vary between main and secondary lines.
Maintenance and Precautions
Regular inspection for cracks or leaks is recommended, especially in high-pressure systems. For PVC/HDPE tees, avoid exposure to UV radiation or extreme temperatures beyond the material’s rating. During installation, ensure proper alignment and use compatible adhesives (for solvent-weld fittings) or gaskets (for threaded variants). Misalignment can cause stress fractures over time. Always follow the manufacturer’s pressure and temperature limits to prevent premature failure.
B2B Procurement Guide
1. **Material Selection**: Confirm compatibility with the fluid type (e.g., HDPE for corrosive chemicals, PVC for cold water). 2. **Certifications**: Look for ISO 9001 or ASTM-certified products to ensure quality standards. 3. **Bulk Pricing**: Orders of 100+ units often qualify for discounts (approx. 10–20% reduction). 4. **Supplier Evaluation**: Prioritize vendors offering technical support and customization (e.g., flanged ends or anti-static coatings).
