3. Key Features & Advantages
- Flow Optimization:
- Concentric reducers minimize turbulence; eccentric reducers prevent airlocks in horizontal pipes.
- Tapered design reduces pressure drop by 15% vs. abrupt diameter changes.
- Material Versatility:
- Stainless Steel: Ideal for corrosive media (chemicals, food, pharmaceuticals).
- PVC-U/PP: Lightweight and cost-effective for drainage/sewage systems.
- Precision Engineering:
- Cold-formed or hot-pressed manufacturing for consistent wall thickness.
- Beveled ends (30°/37.5°) for full-penetration welding.
- Interchangeability:
- Compatible with ANSI/DIN/JIS flanges and pipe schedules.
4. Quality & Compliance
- Certifications:
- ISO 9001:2015 Quality Management System.
- PED 2014/68/EU (EU Pressure Equipment Directive).
- Third-party inspections (SGS, BV, TÜV) available.
- Testing:
- 100% dimensional inspection (calibrated gauges).
- Hydrostatic testing (1.5× working pressure, 30-min hold).
- PMI (Positive Material Identification) for alloy verification.
- Traceability:
- Laser-etched heat number and batch code on each reducer.
5. Applications
- Oil & Gas: Pipeline diameter transitions, wellhead connections.
- Water Treatment: Pump suction/discharge lines, filtration systems.
- HVAC: Chiller loops, variable flow systems.
- Power Generation: Boiler feedwater, steam condensate lines.
- Marine: Ballast systems, bilge piping.
