High-precision ASME 90 degree elbows from a leading China factory. Our suppliers provide B16.9 and B16.28 compliant fittings for petroleum and power generation, ensuring superior sealing and pressure-bearing capabilities.
The ASME 90° Elbow is a high-precision industrial pipe fitting engineered to facilitate seamless 90-degree directional changes within complex pipeline systems. Manufactured in strict accordance with global benchmarks such as ASME B16.9 and ASME B16.28, this component is essential for redirecting fluid flow while maintaining absolute sealing integrity and superior pressure-bearing capabilities across the most demanding industrial environments.
Designed for versatility and durability, our 90° elbows are deployed across critical sectors including petroleum, petrochemicals, natural gas, power generation, and shipbuilding. By providing a robust connection between pipe sections of identical or varying diameters, these fittings ensure optimal hydraulic performance and structural stability, mitigating fluid resistance and preventing system leakage under extreme operating conditions.

| Performance Metric | Standard Fittings | Our ASME 90° Elbows |
|---|---|---|
| Installation Speed | Moderate | High (Precision Bevels) |
| Fluid Efficiency | Variable | Optimized (Low Resistance) |
| Lifespan (Corrosive) | Short-Medium | Extended (A403 Grade) |
| Leakage Risk | Standard | Ultra-Low (Strict Tolerances) |
| Maintenance Cost | Periodic | Minimal (High Durability) |
Long Radius elbows have a curvature of 1.5 times the nominal diameter, offering lower fluid resistance. Short Radius elbows have a 1.0 diameter curvature, making them ideal for tight spaces where higher resistance is acceptable.
For high-corrosion environments, Stainless Steel grades such as A403 WP316/316L are recommended due to their superior resistance to acids and chlorides.
Yes, all our elbows are manufactured to ASME B16.9 and ASME B16.28 standards, with pipe ends machined to ASME B16.25 bevel specifications for secure butt welding.
Our elbows cover a wide range of pressure ratings in accordance with ASME B16.5 and B16.47, including Class 150, 300, 600, 900, 1500, and 2500.
Yes, for low-temperature service, we offer Carbon Steel A420 WPL6, which is specifically designed to maintain toughness and integrity in cold environments.
We utilize precision measurement tools to ensure the turning angle tolerance is strictly controlled within ≤ ±1°, ensuring perfect pipeline alignment.
