The difference between the flange and carbon steel flanges

material is carbon steel flange is called carbon steel flange, is two large diameter pipe connection device, usually two flange and number of the bolt. Carbon steel flange is made of carbon steel flange. Low carbon steel and plastic good strength is low, after adding suitable amount of carbon becomes hard, plastic lower strength enhancement. Flange connection may need to bear very high tensile, compression, torsion, shear strength, the carbon steel flange is a better choice.
can live flange is activity of flange, generally is matching on the water supply and drainage fittings ( Expansion joints on the most common, manufacturer factory will each have a piece of flange on both ends of the expansion joints, directly with the engineering of piping, equipment, bolting. Is the kind of flange with movable set of general use on the pipeline, in that case, the pipeline on both sides of the loose bolts can rotate, can tighten again convenient dismantling pipeline.
