About this product
Product information from the supplier.
Our high-precision 45° Elbows are engineered for critical pipeline redirections, offering a seamless transition that minimizes flow resistance and optimizes fluid dynamics. Designed to meet the rigorous demands of modern industrial infrastructure, these fittings ensure structural integrity and leak-proof performance across a vast range of nominal pipe sizes from 1/2 inch to 48 inches.
Combining advanced metallurgical selection with strict adherence to ASME and ASTM international standards, our 45° elbows are the preferred choice for high-pressure environments. Whether for cryogenic LNG transportation or high-temperature steam systems, these components provide the reliability and precision required for petrochemical, power energy, and marine applications.

Frequently Asked Questions
Q: What is the difference between a 45° elbow and a 90° elbow?
A 45° elbow provides a gradual change in direction, which reduces fluid turbulence and pressure drop compared to the sharp turn of a 90° elbow, making it ideal for high-flow systems.
Q: Which material is best for corrosive chemical environments?
For corrosive media, we recommend Stainless Steel (316/316L) or specialized non-metal materials like PVC and PPR, depending on the specific acid-alkali concentration and temperature.
Q: What does "Schedule" (e.g., Sch 40, Sch 80) refer to in elbows?
The "Schedule" refers to the wall thickness of the fitting. A higher schedule number indicates a thicker wall, allowing the elbow to withstand higher internal pressures.
Q: Are these 45° elbows suitable for high-temperature steam?
Yes, our alloy steel (e.g., A234 WP11/WP22) and high-grade carbon steel elbows are specifically designed to handle steam systems with temperatures exceeding 1000°C.
Q: What is the advantage of Butt Weld (BW) over Socket Weld (SW)?
Butt Welding provides a stronger, seamless joint and is suitable for larger diameters and higher pressures, whereas Socket Welding is faster for small-bore piping (NPS ≤ 2").
Q: Do your products comply with ASME B16.9 standards?
Absolutely. All our factory-made wrought buttwelding fittings are manufactured and tested in strict accordance with ASME B16.9 and ASTM material specifications.
