Top Rated Manufacturer of Plate Flange in India, Available in Different Dimensions
There are many Plate flange manufacturers in India, but the one which is reputed and well-known in the market is regal sales coporation. ASME B16.5 Plate Flange has all the chemical and mechanical properties that make the product to work smoothly. It is the one where unique dimensions, weights and other specifications are provided. It is designed in the form of a plate or ring which connects two pipes and the parts of bolted together. We are an ISO certified firm with 20 years old organization. The raw materials used by us are of supreme quality and based on that the product is manufactured.
They are ANSI B16.5 flanges of class 150 made of plates and used in normal environment and come in different dimensions and types. These are made by using carbon steel and it is employed in chemical, sugar mills and distillary, fertilizer industries, cement industries and other section. These are tested with an advanced equipment and based on this the product is manufactured.
Flat faced plate flanges are not to be bolted to a raised face flange. These are used in chemical industry, plumbing, heating, oil and gas pipeline. These are available in different sizes. It has the gasket surface and in the same plane and this is used in order to remove the bending moment put on the flange when the bolts are torque.
