ASME B16.11 Street Elbow: Dimensions | Specifications | Material Grade | About Street Elbow | All Product Types

A Street Elbow is a 90-degree forged pipe fitting with one male and one female end, used to connect pipes in confined spaces without the need for a nipple. This unique configuration makes it highly efficient in space-restricted environments such as refineries, chemical plants, power stations, and marine piping systems. Street elbows are preferred where compact design, alignment, and ease of connection are crucial.

Manufactured in full compliance with ASME B16.11, BS 3799, and MSS-SP-79, these elbows are offered with Socket Weld (SW) or Threaded (NPT/BSP) ends. Available in sizes from ¼” to 4” and pressure classes of 2000#, 3000#, 6000#, and 9000#, our fittings are ideal for both standard and high-pressure applications.

What is a 90° Street Elbow, and how is it used in piping systems?

A 90° Street Elbow is a vital component in piping systems that is specifically designed to connect two pipes at a right angle (90°) with threaded connections. Unlike standard elbows, a Street Elbow has one male thread on one side and a female thread on the other, making it unique for connecting to pipes or fittings with corresponding thread types (such as NPT or BSPT).

These elbows are typically used in situations where a sharp directional change in the flow of liquids, gases, or slurries is needed in confined spaces. Due to their threaded design, they are popular in systems where welding isn’t feasible, and quick assembly and disassembly are essential.

Common industries that use 90° Street Elbows include:

  • Oil & Gas: For connecting pipes in drilling rigs, pipelines, and refinery systems.
  • Marine: In shipbuilding and offshore platforms where flexibility and resistance to corrosion are crucial.
  • Petrochemical: For redirecting fluid flows in reactors, heat exchangers, and pipelines.
  • Plumbing & HVAC: In residential and commercial installations to navigate tight spaces and redirect pipe flows.

The materials used for manufacturing these elbows—such as carbon steel, stainless steel, alloy steel, duplex, super duplex, and high-nickel alloys—ensure strength, durability, and resistance to harsh conditions like high pressure, extreme temperatures, and corrosive environments. Whether in high-pressure applications or standard low-pressure systems, 90° Street Elbows are reliable for ensuring a smooth, uninterrupted flow of materials while maintaining the integrity of the system.

Quality Assurance and Certifications of Street Elbows

At Nutech Overseas, every Street Elbow is manufactured under strict quality protocols to ensure long-lasting performance, precision, and compliance with global standards.

All Street Elbows are produced with complete traceability of raw materials, supported by Mill Test Certificates (MTCs) as per EN 10204 3.1 and 3.2, Third Party Inspection (TPI) reports (if applicable), and Hydrostatic/Pressure Test Reports. The fittings conform to international standards such as:

  1. ANSI/ASME B16.11
  2. BS 3799
  3. MSS-SP-79 / SP-83 / SP-95 / SP-97

Each fitting undergoes 100% visual inspection, along with:

  • Dimensional checks
  • Thread gauging for NPT/BSP compliance
  • Non-Destructive Testing (NDT) such as Ultrasonic Testing (UT) or Dye Penetrant Testing (DPT) as required

What is the Difference Between a Street Elbow and a Regular Elbow?

A Street Elbow differs from a standard elbow primarily in the connection type. While a regular elbow requires two female ends or two male ends for pipe connection, a Street Elbow features one male and one female connection. This unique design allows it to connect a male-threaded pipe to a female-threaded pipe, typically used in compact piping systems where space is limited, or in systems requiring an immediate directional change.

  • Applications: Common in low-pressure systems, plumbing, or light industrial applications.
  • Size Range: Typically available in smaller sizes, such as ¼" to 4".
  • Materials: Street Elbows are made from materials like carbon steel, stainless steel, and alloy steels, ensuring compatibility with various fluids and environments.

This design feature of a male and female threaded end makes Street Elbows highly versatile in applications that demand flexibility and space efficiency.

How Do Temperature and Pressure Affect the Performance of Street Elbows?

The performance of Street Elbows is significantly influenced by temperature and pressure conditions, making it critical to choose the right material and design for each specific application. The elbow's pressure rating is a key determinant, but it's also crucial to consider how temperature variations impact its ability to maintain structural integrity.

  • Temperature Effects: As the temperature rises or falls, the material of the Street Elbow expands or contracts. For stainless steel and alloy steels, high temperatures may reduce material strength, while low temperatures can make the material brittle, leading to potential cracking under pressure.
    • High-temperature environments (above 300°C) typically require alloy steels or high-nickel alloys such as Inconel or Monel, which have better resistance to thermal expansion and degradation.
    • Cryogenic temperatures (below -100°C) necessitate materials like carbon steel A350 LF2, which is designed for low-temperature resilience.
  • Pressure Effects: The internal pressure within the pipeline can increase the stress on the elbow. The higher the pressure, the more likely it is that the elbow will experience stress fatigue, especially in high-pressure applications where Class 9000 pressure ratings are required. For this reason, choosing a Street Elbow with a pressure rating that exceeds the expected system pressure is important to prevent failure.
