Product Description

Butt-welding Pipe Fittings 45D Long Radius Elbow ASTM A234 WPB 2''SCH80 ASME B16.9

1. Product Introduction

The Stainless Steel Butt Weld Elbow is a premium pipe fitting designed to redirect pipeline flow at 45° or 90° angles. Manufactured from 304 or 316L stainless steel, it features a butt-welding connection that ensures a permanent, leak-proof joint with superior strength. Fully compliant with ASME B16.9 and GB/T 12459 standards, our elbows are widely used in oil and gas, chemical processing, power generation, and water treatment industries.

3. Applications

Our elbows are essential for directional changes in pipeline systems across multiple industries:

  • Oil & Gas: Crude oil, refined products, and high-pressure gas transmission.

  • Chemical Processing: Corrosive fluids including acids, alkalis, and salt solutions.

  • Power Generation: Steam and boiler feedwater lines under extreme temperatures.

  • Pharmaceutical & Food: Sanitary-grade pipelines for clean fluid transfer.

  • Environmental Engineering: Wastewater treatment and desalination plants.

4. Product Advantages

  • Corrosion Resistance: 304 grade offers excellent general corrosion protection; 316L with molybdenum addition provides superior resistance to pitting and crevice corrosion in chloride-rich environments.

  • High Strength & Reliability: Stainless steel delivers high tensile strength and toughness. The butt-weld joint eliminates threaded weak points, significantly reducing leakage risks.

  • Precision Manufacturing: Strict dimensional control ensures smooth internal surfaces, accurate angles, and minimal flow resistance.

  • Standard Compliance: Fully compliant with ASME B16.9 and ASTM A403, ensuring global compatibility.

  • Custom Solutions: We offer customized sizes, wall thickness, and surface finishes with competitive lead times.

5. Function

The elbow redirects fluid or gas flow at a precise angle while maintaining a smooth, continuous passage that minimizes turbulence, pressure drop, and erosion. Once welded, it becomes an integral part of the pipeline, capable of withstanding thermal expansion, vibration, and mechanical stress.

6. Usage Instructions

  • Preparation: Clean and bevel pipe ends; remove oil, rust, and debris.

  • Alignment: Properly align elbow with pipe axis to avoid misalignment.

  • Welding: Use TIG or MIG with matching filler metal (ER308L for 304, ER316L for 316L).

  • Post-Welding: Apply pickling and passivation; inspect weld quality via visual or NDT methods.
