What Are Square Flange?


A asme b16.5 square flanges is made in our factory keeping in accordance with JIS B2291 / JIS F7806 standards. Generally a Hydraulic Square Flange is used between either a pipe to pipe or a pipe to components type of connections. These square shaped flanges are mostly used in a hydraulic systems line where there is a passage of fluids. As is typical of these flanges, the slip on square flange is made from two materials i.e. either steel or stainless steel.

how to use a flange square

How To Use A Flange Square?

In addition to this hydraulic square flange produced from grade 316 exhibits good welding properties, which is why our clients prefer using these flanges. As square flanges manufacturers in India, we discourage the use of larger loads on the flange, especially in those times when subjected to higher torque.


Why Hydraulic Lines Have Square Flanges

Just as the other Fittings and products that are manufactured in our factory, the asme b16.5 square flange has been produced using the finest quality raw material we procure from our vendors. And, the Hydraulic Square Flange also go through a rigorous quality check across all stages of production, which in turn ensures that our buyers get the best quality square base flange. A key feature of the 1 inch square floor flange is that this type of flange can be attached to pipes without having the need to weld. Although occasionally, there could be a requirement of a seal weld to be used on the welding flange square.
