OVERVIEW

90deg Elbow

TUBA pride ourselves on being a leading manufacturer, exporter and supplier of a diverse range of Buttweld 90 Degree Elbow which is being produced using high quality raw materials. These Elbows has the corrosion resistance, dimensionally precise and accurate, durable, long-lasting in nature and rust-free properties in the water applications. We manufacture these 90° Long Radius Elbows by using the tested and the best quality of raw materials and offer these Elbows at the affordable prices to our esteemed clients.

The 90 degrees elbows is the most common among elbows. There are different types such as the 90 Degree Short Radius Elbow. The 90 degree 3d elbows has a 90 degree angle and a radius 3 times that of the pipe diameter. This helps the fluids or gases to gradually excerpt pressure on the walls rather than suddenly.

The function of a 90 Degree Long Radius Elbow is same as 90 degree long and short elbow, but the measurement and dimensions is different to that of a 90 degree long and the short elbow. There are low pressure and high pressure elbows with different variations such as the Schedule 10 short radius elbow. The short radius and long radius of the elbow could be marked as SS or LS respectively. The 90 degree elbow is used in Furnesses or other heating or cooling applications. Our pipe elbows are of high quality and offer a great resistance to corrosion. We have 90 degree elbow in materials like Stainless Steel 90 Degree Elbow, Hastelloy 90 Degree Elbow, Inconel 90 Degree Elbow, Monel 90 Degree Elbow, Duplex Steel 90 Degree Elbow, SMO 254 90 Degree Elbow etc.
