Buttweld 90-degree elbows are essential components in piping systems, offering efficient directional changes in fluid flow. Manufactured to precise dimensions as specified by ASME/ANSI B16.9, ASME B16.28, and MSS-SP-43 standards, these elbows ensure compatibility and reliability in various applications. They come in a wide range of sizes, from seamless elbows and ERW, welded, or fabricated elbows.
The types of buttweld 90-degree elbows include seamless, ERW, welded, and fabricated options, catering to different needs and applications. They are produced in various thicknesses, such as Schedule 5S to XXS, ensuring durability and performance under diverse conditions. Available forms include long radius (LR) and short radius (SR) elbows, suitable for different flow dynamics and spatial constraints.
These elbows boast several advantages, such as high strength, resistance to corrosion and pressure, and the ability to withstand extreme temperatures. Their smooth interior surface minimizes pressure drops and turbulence, enhancing flow efficiency. Buttweld 90-degree elbows are widely used in industries such as oil and gas, petrochemicals, power generation, pharmaceuticals, and shipbuilding, where reliable and efficient fluid conveyance is critical.
Their robust construction and adherence to stringent quality standards make buttweld 90-degree elbows a preferred choice for demanding applications. Whether for seamless, ERW, welded, or fabricated types, these fittings ensure long-lasting performance, contributing to the overall safety and efficiency of piping systems.

A 90-degree elbow is a pipe fitting used to change the direction of flow by 90 degrees. It is available in two types:
Long Radius (LR): Has a centerline radius 1.5 times the pipe diameter; ideal for smoother flow with minimal pressure loss.
Short Radius (SR): Has a centerline radius equal to the pipe diameter; used in tight spaces where flow efficiency is less critical.
