Materials and Surface Treatment
We fabricate these fittings from premium pliable press that gives amazing ductile quality and ductility. The fabric withstands weight surges and warm cycling without splitting or deformation.
The hot-dip galvanizing handle includes submerging the wrapped up fittings in liquid zinc at 850°F. This makes a metallurgical bond between the zinc and base metal. The result is a coating that ensures indeed if scratched amid installation.
Our quality control guarantees reliable coating thickness over all surfaces. The zinc layer gives cathodic assurance that expands fitting life altogether in destructive environments.
Standards and Certifications
All our fittings comply with relevant industry standards:
- ASME B16.3 for dimensional requirements
- ASTM A197 for malleable iron material specifications
- ASTM A153 for galvanizing standards
- ASME B1.20.1 for NPT threading
Our fabricating office works beneath ISO 9001 quality administration framework. This guarantees reliable item quality and traceability all through production.






Application Areas
These NPT Galvanized Female-Female 90° Long Radius Elbow Pipe Fittings excel in various industrial and commercial applications:
Industrial Compressed Discuss Frameworks: Idealize for pneumatic lines where keeping up weight is significant. The long span plan anticipates vitality misfortunes that increment working costs.
HVAC Hydronic Frameworks: Perfect for hot water circulation where turbulence can cause erosion-corrosion. The smooth stream way amplifies framework component life.
Outdoor Plumbing: Great for uncovered channeling subject to climate. The galvanized coating gives solid assurance against air corrosion.
Agricultural Water system: Handles high-volume water stream productively whereas standing up to erosion from fertilizers and soil contact.
Fire Security Frameworks: Keeps up water weight by minimizing contact misfortunes amid crisis operation.
Installation Instructions
Proper establishment guarantees ideal execution and anticipates spills. Clean all strings completely some time recently gathering. Apply fitting string sealant or tape to male pipe strings only.
Hand-tighten the association to begin with. At that point utilize pipe torques to total the joint. Dodge over-tightening which can harm the galvanized coating or strip threads.
Support the channeling framework satisfactorily to avoid stretch on the fittings. Permit for warm extension in frameworks with temperature variations.
Test all associations at working weight some time recently putting the framework into service.
Packaging and Shipping
We bundle fittings carefully to ensure the galvanized coating amid travel. Person poly packs anticipate scratching between pieces. Strong cartons with padding guarantee secure delivery.
Standard bundling amounts shift by estimate. We can suit uncommon bundling prerequisites for huge orders. All shipments incorporate nitty gritty pressing records and fabric certificates.





Quality Control
Every fitting experiences thorough assessment some time recently shipping. We check measurements, threading precision, and coating astuteness. Weight testing confirms auxiliary judgment at evaluated pressures.
Our quality group performs normal reviews of generation forms. This keeps up the tall guidelines you anticipate from Zhiyuan products.
OEM and Customization Services
We offer customization choices for uncommon applications. This incorporates non-standard sizes, weight evaluations, and fabric grades. Our designing group works with you to create arrangements that meet particular requirements.
