Technical requirements of stainless steel elbow

　　Stainless steel elbow: in pipe system, two pipes with the same nominal diameter are connected, so that the pipe can be turned at a certain angle. The classification of elbow: according to the angle, the most commonly used are 45 degrees, 90 degrees and 180 degrees three, and according to the needs of the project can also include 60 degrees and other abnormal angle elbow. The way of connection with pipes is: direct welding (the most common way), flange connection, threaded connection and socket connection.

　　technical requirement

　　1.Because most of the ASTM B363 Stainless Steel Welded Pipe Fittings Elbow is used for welding, in order to improve the welding quality, the end is all turned into a slope, leaving a certain angle and with a certain edge. This requirement is also strict, the edge is thick, the angle is as much as the range and the range of the deviation are all stipulated. The surface quality and mechanical properties are basically the same as those of pipes. For the convenience of welding, the fittings of the pipe and the connected pipe are the same.

　　2 It is the requirements for the packaging for small pipes, such as the export, the need to do wooden cases, about 1 cubic meters, which stipulates that the number of bends in this box can not exceed one ton. The standard allows a suit, that is, a large set of small sets, but the total weight is generally not more than 1 tons. For large y, a single package is required, like 24 ', which must be packed individually. Another is the packaging mark, marking is the size, the steel number, the batch number, the manufacturer trademark and so on.
