The use and characteristics of rolling flanges

Rolling flanges are widely used,and the scope of use is determined according to different characteristics.It is mostly used in the case of moderate media conditions,such as low pressure non-purified compressed air and low pressure circulating water.

The advantage of rolling flange is that the price is relatively cheap.The rolling flange is suitable for steel pipe joints with a nominal pressure not exceeding 2.5 MPa.The sealing surface of the rolled flange can be made into a smooth type,a concave-convex type and a grooved type.The smooth rolling flange has the largest application amount.Two other types of rolled flanges are also common in use.

Rolling flanges are available in many types and models.Welded steel flanges are used for flange and tube butt welding.They are mainly used in welding technology and have good performance characteristics.The structure is reasonable, and the strength and rigidity are large.It can withstand high temperature and high pressure, repeated bending and temperature fluctuation, and has reliable sealing performance. The rolled flange with nominal pressure of 0.25~2.5MPa adopts concave and convex sealing surface.The main application environment of the coiled flange is suitable, and it needs to be determined according to the specific conditions to ensure the specific use value and performance of the rolled flange, and to withstand high temperature and high pressure.
