Elbows

Steel Pipe Elbows

Our industrial steel elbows are precision-engineered to change the direction of fluid or gas flow within a piping system. Available in 45°, 90°, and 180° configurations, these fittings are manufactured to withstand high-pressure environments, extreme temperatures, and corrosive conditions across the oil, gas, and power sectors.

1. Technical Specifications

Degrees:45°, 90°, 180° (Short Radius & Long Radius).

Radius Types:*Long Radius (LR):Center-to-face distance is 1.5 times the nominal pipe size (R=1.5D).

Short Radius (SR):Center-to-face distance is equal to the nominal pipe size (R=1.0D).

Size Range:1/2" to 72" (DN15 – DN1800).

Wall Thickness:SCH 5S to SCH XXS.

2. Material Grades & Standards

We offer a comprehensive range of materials to ensure chemical compatibility with your pipeline:

Carbon Steel:ASTM A234 WPB, WPC; ST37.2, A105.

Stainless Steel:ASTM A403 WP304/304L, WP316/316L, 321, 310S.

Alloy Steel:ASTM A234 WP1, WP5, WP9, WP11, WP22, WP91.

Low Temperature:ASTM A420 WPL3, WPL6.

High Yield:MSS-SP-75 WPHY 42, 52, 60, 65, 70.

3. International Manufacturing Standards

All elbows are produced and strictly tested in accordance with global industrial requirements:

ASME/ANSI B16.9(Factory-Made Wrought Buttwelding Fittings)

ASME B16.11(Forged Fittings, Socket-Welding and Threaded)

DIN 2605(Steel Butt-Welding Pipe Fittings; Elbows)

JIS B2311 / B2312 / B2313

EN 10253(Butt-welding pipe fittings)

4. Key Features & Applications

Flow Efficiency:Smooth internal surfaces minimize friction and turbulence in high-velocity systems.

Versatile Connections:Available in Butt-Weld (BW), Socket-Weld (SW), and Threaded (NPT/BSPT) ends.

Surface Treatment:Provided with Black Vanish, Anti-rust Oil, Hot-dip Galvanized, or Pickled & Passivated finishes.

Broad Application:Critical for Petrochemical Refineries, Offshore Platforms, Power Generation, Water Treatment, and Shipbuilding.

5. Quality Control & Logistics

Testing:100% Dimensional Inspection, Ultrasonic Testing (UT), Magnetic Particle Inspection (MPI), and Hydrostatic Testing.

Certification:Fully compliant withMTC (EN 10204 3.1); third-party inspection (SGS, BV, TUV) accepted.

Packaging:Securely packed in seaworthy wooden cases or on pallets with protective wrapping to prevent transit damage.

Frequently Asked Questions

1. When do buyers usually debate between elbows and bends?

They usually debate it when flow behavior, layout space, and fabrication convenience are all in play. The right choice is often less about catalog names and more about what the pipeline needs to do in the field. Typical long-tail phrases include 90 degree carbon steel elbow, long radius elbow for process piping, and ASTM A234 WPB butt weld elbows.

2. Why can elbow prices vary so much for common sizes?

Variations often come from schedule, radius, forming route, testing scope, and whether the order is part of a larger matched fitting package. Buyers often underestimate the effect of those details. This price difference often shows up in 90-degree long radius elbow supply for oil and gas, refinery, or power plant piping.

3. What is the most useful buyer question before choosing long radius or short radius elbows?

A very useful question is whether installation space or flow smoothness matters more in the actual piping run. That usually settles the choice faster than comparing drawings in isolation. That question matters most in process piping, utility piping, and project MTO review for oil, gas, and water systems.

4. What do buyers most often miss when reviewing elbow offers?

They often miss whether the quoted elbows match the real schedule and piping family used elsewhere in the job. That alignment matters more than first-time buyers expect. Fit-up problems are common when butt weld elbow schedule and radius are not aligned with the actual piping line list.
