Precautions for use of SO Flange
SO Flange is the use of turning edge, steel ring and other flange set on the pipe end, the flange can move on the pipe end. Steel ring or rim is the sealing surface, the flange is to press them. Thus, SO Flange does not contact the medium because it is blocked by the steel ring or rim. Because the flanges are movable and are not directly connected to the pipes, they are called live sleeve flanges, and there is another saying called loose sleeve flanges. SO Flange has two kinds of Welding ring SO Flange and flip edge SO Flange . Assembly of sleeve flange and pipe. During the assembly, the flange is also placed on the pipe first, and then a turning ring is welded on the pipe end, or turning the edge is made directly at the pipe mouth. The end surface of the edge should be perpendicular to the centerline of the pipe, the width of the edge should meet the requirements, the surface should be smooth, straight, without wrinkles, cracks and other injuries. PVC tube tipping edge. When turning, use 130~140℃ of medium to heat the end of the pipe for 5~10min to make it soft, and then expand it into a trumpet, and then flatten it with the tire turning rim, and cool it down. In the assembly of SO Flange should be noted: must put the flange on the pipe, and then turn the edge or welding ring, otherwise it will not be installed on the flange, resulting in rework waste. One side of the inverted corners of the flange hole must be pressed on the turning edge or on the welding ring against the sealing surface of the welding ring. Turn edge SO Flangeflange copper tube flip edge, flip edge money should draw the length of the flip edge, and annealing treatment, make the pipe end becomes soft, and then set it on the flange with a small hammer small head evenly knock, put into a horn shape, and then with the hammer big head of the horn mouth can be flat. Lead tube edge, lead tube is soft, can be used oak or birch hammer directly knock the edge, its method is the same as copper tube edge method.
