Medium 90° Long Radius Weld Elbow — BS 1965 / EN 10253-2
Engineered for high-performance pipework, the Medium 90° Long Radius Weld Elbow delivers a precise right angle directional change without compromising flow efficiency. centerline radius measures 1.5 times the nominal pipe diameter (R = 1.5D), producing a gradual, sweeping bend that minimizes turbulence, reduces pressure drop, and extends the service life of the pipeline compared to short-radius alternatives.
The medium duty wall thickness is designed to pair seamlessly with medium-weight steel tubes, including those formerly specified under BS 1387 / BS EN 10255 ensuring a structurally consistent connection throughout a system. Both ends feature a precision bevel finish, enabling direct butt-welding into the pipeline for a permanent, leak free joint that holds up under demanding operating conditions.
Manufactured to BS EN 10253-2, the current standard superseding the original BS 1965 specification, this elbow meets the rigorous requirements of pressure critical applications. It is a trusted component across oil and gas extraction, chemical & petrochemical processing, nuclear power generation, water & wastewater treatment, natural gas transmission, and general engineering fabrication. 

Summary: 

• Features a medium-duty wall thickness, typically designed to connect with medium-weight steel tubes (such as those formerly governed by BS 1387 / BS EN 10255)
• The ends of the elbow are beveled to allow direct butt-welding into the pipeline
• Creates a leak-free, permanent joint capable of withstanding full service
• Creates a smoother transition for materials passing through, which reduces turbulence, wear-and-tear, and pressure loss compared to short radius elbows

Applications: 
Commonly used in;

• Oil and gas extraction and refining
• Chemical and petrochemical processing
• Nuclear power generation
• Water and wastewater treatment
• Natural gas transmission
• General engineering & fabrication
