We, HGFF GROUP CO., LTD., have an experience spanning for over three decades, producing and supplying best-in-class products, minimizing cost by getting manufacturing processes under one roof and delivering consignments on a daily basis only because of a diligent and dedicated team. We are manufacturers, suppliers, and exporters of Buttweld 180° Pipe Elbows, which are also known as ‘return elbows’, functioning to change the direction of the flow through a 180° angle. These SS 304 Buttweld 180 Degree Elbows are also available in customized sizes that give more elasticity and ease of handling in the process and control systems. Ancient to operate under a range of Buttweld 180 Degree Elbow, SS 180 deg. Elbow, 180-degree Buttweld Elbow extreme and actuating temperatures, our ANSI B16.9 180° Elbows are exported to many chemicals, engineering and industrial businesses in Africa, Europe, middle eastern and South East Asian countries.
