Materials and Surface Treatment
We utilize high-quality pliable press that meets ASTM A197 benchmarks. This fabric gives great ductility and quality for requesting applications. Our hot-dip galvanizing prepare applies a defensive zinc coating that acts as a conciliatory boundary against erosion. The galvanized wrap up expands benefit life in open air and marine environments.
Standards and Certifications
All our fittings comply with relevant industry standards:
- ASME B16.3 (Malleable Iron Threaded Fittings)
- ANSI/ASME B1.20.1 (Pipe Threads)
- ASTM A153 (Zinc Coating Standards)
- ISO 9001 Quality Management System






Application Areas
These flexible fittings serve numerous businesses where you require effective stream redirection. Mechanical compressed discuss frameworks advantage from diminished weight drops that keep up pneumatic instrument execution. HVAC establishments utilize these fittings in return lines where stream effectiveness decreases pump strain. Water treatment offices depend on the smooth inside geometry to anticipate silt buildup. Rural water system frameworks appreciate the climate resistance and turbulence lessening that secures downstream equipment.
Installation Instructions
Before establishment, assess strings for harm and clean all surfaces. Apply fitting string sealant to male strings as it were. Hand-tighten the fitting, at that point utilize a torque to total the association. Do not over-tighten as this may harm the strings. Guarantee legitimate back for associated channeling to avoid stretch on the fitting.
Packaging and Shipping
We package these NPT Galvanized Male Female 90° Long Radius Elbow Pipe Fittings carefully to avoid harm amid transport. Little sizes come in defensive plastic packs, whereas bigger fittings utilize person cartons. Our coordinations arrange guarantees provoke conveyance with following data given. Standard shipping choices incorporate ocean cargo for expansive orders and express conveyance for pressing requirements.





Quality Control
Our quality administration framework guarantees reliable item execution. Each fitting experiences dimensional review and weight testing. String gaging confirms NPT compliance, whereas coating thickness estimations affirm galvanizing benchmarks. Arbitrary testing incorporates fabric examination to confirm chemical composition and mechanical properties.
OEM and Customization Services
With over 26 a long time of casting encounter, we offer customization administrations for uncommon applications. Our designing group can adjust measurements, materials, or surface medications to meet your particular prerequisites. Least arrange amounts apply for custom items, and lead times shift based on complexity.






Frequently Asked Questions
Q: What's the difference between long radius and standard elbows?
A: Long radius elbows have a wider sweep (1.5D) that reduces flow turbulence and pressure loss compared to standard radius fittings.
Q: Can these fittings handle high-pressure applications?
A: Our standard fittings are rated for Class 150 (300 PSI). Higher pressure ratings are available upon request.
Q: How long does the galvanized coating last?
A: In typical industrial environments, hot-dip galvanizing provides 20-50 years of corrosion protection.
