90 Degree Galvanized Steel Bend
Product Overview
Shanxi Bote 90 degree galvanized steel bend is a premium pipe fitting manufactured from national standard KTH330-08 malleable cast iron with hot-dip galvanizing treatment for comprehensive corrosion and rust protection. Available in both equal-diameter and reducing female thread configurations, this 90° elbow is designed for vertical direction changes in pipeline systems.
Widely specified in fire sprinkler, water supply and drainage, HVAC and gas pipeline engineering, this fitting delivers 1.6MPa pressure resistance with complete size range from DN15 to DN100. Precision-engineered internal threads ensure tight sealing performance and reliable leak-free operation. As an essential component in galvanized pipe networks, it pairs seamlessly with all standard galvanized steel systems.
Manufactured in strict compliance with GB/T3287 national standards, each bend is supplied with factory certificates and inspection reports to meet engineering acceptance requirements. Beyond plumbing applications, it also serves supporting roles in galvanized hardware assemblies, galvanized sheet metal fabrication projects and galvanized fencing infrastructure systems.

Product Features & Advantages
1. Full Hot-Dip Galvanized Corrosion Protection
Uniform zinc coating covers both interior and exterior surfaces through hot-dip galvanizing process, forming a metallurgically bonded protective layer that effectively resists rust, oxidation and chemical corrosion across all galvanized pipe installations.
2. Precision Machined Threads for Tight Sealing
CNC threaded female connections feature consistent pitch and smooth surface finish. When assembled with galvanized steel pipes, the precisely tapered threads create a secure, leak-proof joint that maintains sealing integrity under long-term pressure.
3. Complete Size Range with Dual Configurations
Full DN15-DN100 specification coverage with both equal and reducing diameter options available. This comprehensive inventory supports diverse pipeline layout requirements and matches all mainstream galvanized hardware fitting systems on the market.
4. High Strength Malleable Cast Iron Construction
KTH330-08 grade material provides excellent tensile strength, impact resistance and ductility after specialized heat treatment. The 1.6MPa pressure rating ensures reliable performance across demanding hydraulic and pneumatic pipeline applications.
5. Certified Quality with Full Documentation
Every batch meets GB/T3287 national standards with complete factory certificates and inspection reports. Full traceability documentation supports smooth project acceptance, international procurement filing and customs clearance procedures.
6. Versatile Cross-Industry Application
Beyond core plumbing systems, these galvanized bends integrate into galvanized sheet metal assemblies, galvanized fencing support structures and general industrial galvanized hardware kits for broad project utility.
Step-by-Step Installation Guide
- Prepare the pipe end by cleaning the external threads, removing burrs, rust and debris to ensure clean contact surfaces.
- Apply PTFE sealing tape clockwise onto the male threads or use appropriate pipe joint compound to enhance sealing performance.
- Align the 90 degree bend female thread with the pipe end and hand-tighten clockwise until snug engagement is achieved.
- Use two pipe wrenches — one securing the pipe and one turning the fitting — and tighten 2-3 additional turns beyond hand-tight position.
- Verify the 90-degree orientation matches your pipeline layout design before final torque is applied.
- Perform system pressure testing after all connections are completed to confirm no water or gas leakage at joint points.
