Hebei Chiho doubled stainless steel pipe industry is short radius elbow stamping elbow R = 1.0D curvature also commonly used stamping elbow 90 degrees long radius R = 1.5D stainless steel stamping elbow elbow twice used in pipeline installation A connector with a pipe connecting two nominal diameter pipes the same or different, so make sure the line angle turn. 1. Material classified carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum, plastic, argon Ge Lek, PVC, PPR and so on. 2. production methods can be divided into pushing, pressing, forging, casting and so on. 3. manufacturing standards can be divided into GB, electricity standard, water standard, American Standard, the German standard, Japanese standard, the Russian standard and so on. 4. It is the radius of curvature of points: can be divided into long and short radius bend radius elbow. Long radius elbow refers to its radius of curvature is equal to 1.5 times the outer diameter of the tube, i.e., R = 1.5D. Short radius elbow refers to its radius of curvature is equal to the pipe diameter, namely R = 1.0D. (D is the diameter of the bend, R is the radius of curvature). Chiho Hebei Industry stamping elbow high pressure pipe connections, including a curved pipe, characterized in an arcuate elbow integrally connected with a shunt-through. The utility model has reasonable structure, make piping by force , thick-walled elbow piping system can be simplified, easy to operate walled elbow, can save investment, reduce the pipe resistance, optimized piping arrangement, and can help reduce the cost of running a balanced flow distribution, reduce the piping vibration, ensure that the equipment and The advantage of the safe operation of the pipeline elbow materials are cast iron, stainless steel, alloy steel, malleable iron, steel, nonferrous metals and plastics, and the pipe coupling methods are: direct welding (the most common way) flanged ., threaded coupling and socket type coupling, etc. in accordance with the production process can be divided into: welding elbow, pressing elbow, casting elbow 45 degrees elbow high pressure stamping technical requirements: 1. As the most used for welding pipe fittings, in order to improve the welding quality thick-walled seamless elbow, both ends of the car into the groove, leaving a certain angle with a certain edge, this one is also more stringent requirements, how thick edge angle of deviation has a predetermined number and surface quality and mechanical properties of basic and tubes are the same. In order to facilitate welding, pipe fittings and steel pipes to be connected is the same .2 that all the pipe pieces to go through a surface treatment, the inner and outer surfaces of the oxide scale spraying by shot peening off, and then coated with anti-corrosion paint. This is to export needs, moreover, in the country but also to facilitate transport to prevent corrosion oxidation, have to do this work .3 is on the packaging requirements for small fittings, such as exports, on wooden box needs to be done, about one cubic meter, the provisions in this case can not exceed the number of elbows about a ton, the standard allows suits that large sets of small thick-walled elbow 45 degrees, but the total weight is generally not more than 1 ton. For large y should a single package, like 24 "must be individually packaged other is the package label, the label is to indicate the size, steel number, lot number, manufacturer trademark thick-walled elbow |.
