Key Features & Material Advantages
  • Standard Compliance: Strictly conforms to ASME B16.9 and A SA403 standards, ensuring dimensional accuracy, wall thickness uniformity and compatibility with global construction, fire protection and HVAC pipelines.
  • Premium 304/316 Stainless Steel: 304 stainless steel offers good corrosion resistance and cost-effectiveness, suitable for general construction and HVAC scenarios; 316 stainless steel contains molybdenum, with superior anti-rust, anti-acid and salt spray resistance, ideal for humid, high-corrosion fire protection and outdoor construction environments.
  • Versatile Connector Design: Available in 45° and 90° angles, short/long radius options, flexible to adapt to different pipeline layout needs in construction, fire protection and HVAC systems.
  • Strong Sealing & Durability: Precision forming and butt-weld connection ensure tight sealing, zero leakage, high pressure resistance and impact resistance, adapting to long-term continuous operation in harsh working conditions.
  • Easy Installation & Compatibility: Standardized design, easy to weld and install with stainless steel pipelines, reducing construction time and labor costs; compatible with other standard pipe fittings.
Application Scenarios
Our stainless steel elbow connectors are widely used in construction, fire protection and HVAC piping systems, including but not limited to:
  • Construction Piping: Building water supply and drainage pipelines, industrial construction fluid transmission, building decoration pipeline connections.
  • Fire Protection Systems: Fire sprinkler pipelines, fire water supply pipelines, fire extinguishing agent transmission pipelines (resistant to high temperature and pressure).
  • HVAC Systems: Heating pipeline connections, ventilation air duct supporting pipelines, air conditioning water circulation pipelines, ensuring smooth fluid transmission and system efficiency.
Quality & Packaging Service
All elbows undergo strict quality inspection, including chemical composition analysis, pressure test, dimensional measurement and appearance inspection, providing complete MTR test reports. Export-standard packaging (waterproof wrapping + fumigated wooden pallet) ensures no damage during transportation. We support small trial orders and bulk procurement, and provide flexible customization for angle, radius and wall thickness to meet specific project needs.

    These pipe connectors are exactly what we need for residential and garden water systems. Thickened body structure brings good pressure resistance. Surface finish is uniform and elegant. After months of use, no oxidation or thread loosening issues appear. Excellent value for money.
