Product Description
We are trusted manufacturers, suppliers, and exporters of Buttweld 180° Pipe Elbows, also known as return elbows, which are designed to change the direction of flow by a full 180 degrees in a pipeline system. These fittings provide an efficient solution for space-constrained piping layouts and are widely used in process and control systems.
Our SS 304 Buttweld 180° Elbows are available in standard as well as customized sizes, offering greater flexibility and ease of installation. Engineered to perform reliably under a wide range of temperatures, pressures, and flow conditions, these elbows are manufactured in compliance with ANSI/ASME B16.9 standards.
We proudly export our stainless steel 180-degree elbows to clients in various sectors including chemical processing, engineering, power generation, and industrial infrastructure, across Africa, Europe, the Middle East, and Southeast Asia.
