304 / 304L, 316 / 316L, 310 / 310S Stainless Steel Butt Weld Elbow 30 degree, 45 degree, 60 degree, 90 degree, 180 degree In piping systems, elbows are fittings that change the direction of the pipe. According to the angle, there are 45 degree and 90 degree 180 degree three kinds of the most commonly used, in addition to engineering needs, including 60 ° and other non-normal angle elbow. Elbow materials are cast iron, stainless steel, alloy steel, malleable iron, carbon steel, non-ferrous metals and plastics. Pipe connection with the way: direct welding (the most common way) flange connection, hot melt connection, fused connection, screw connection and socket connection. In accordance with the production process can be divided into: welding elbow, stamping elbow, pushing the elbow, casting elbow, elbow and so on. Other names: 90-degree elbow, right-angle bend, love and bend and so on.

304 / 304L, 316 / 316L, 310 / 310S Stainless Steel Butt Weld Elbow 45 degree 90 degree 180 degree Technical Requirement :

1, the majority of 304 / 304L, 316 / 316L, 310 / 310S Stainless Steel Butt Weld Elbow 45 degree 90 degree 180 degree  for welding, in order to improve the quality of welding, the end of the car into a groove, leaving a certain angle, with a certain edge, this one is also more stringent requirements, how thick edge, how much angle and deviation The scope of the provisions. Surface quality and mechanical properties are basically the same as for pipes. For welding convenience, the pipe is the same type of steel as the pipe to be connected.
2, that is, all the 304 / 304L, 316 / 316L, 310 / 310S Stainless Steel Butt Weld Elbow have to go through surface treatment, the inner and outer surface of the oxide coating by shot peening spray, and then coated with anti-corrosion paint. This is for export needs. Moreover, it is also necessary to do the work in this area in order to facilitate the transportation and prevent rust oxidation in China.
3, that is, the packaging requirements For small tube, such as exports, you need to do wooden boxes, about 1 cubic meter, provided that the number of elbows in this box can not exceed about one ton, the standard allows the suit, However, the total weight of the general can not exceed 1 ton. For the large y will have a single package, such as 24 ” must be a single package. The other is the package mark, mark is to indicate the size, steel, batch number, trademark and other manufacturers.

How to maintain the 304 / 304L, 316 / 316L, 310 / 310S Stainless Steel Butt Weld Elbow 45 degree 90 degree 180 degree ?

1, Long-term storage of 304 / 304L, 316 / 316L, 310 / 310S Stainless Steel Butt Weld Elbow 45 degree 90 degree 180 degree , should be checked on schedule, often on the exposed surface to be kept clean, remove dirt, neatly stored indoors in a dry place, non-stacking or open storage. Always keep the stainless steel elbows dry and ventilated, the holder clean and tidy, stored in accordance with the exact method of storage.
2, the installation, 304 / 304L, 316 / 316L, 310 / 310S Stainless Steel Butt Weld Elbow 45 degree 90 degree 180 degree can be connected directly by the device installed in the pipeline, according to the use of the installation location. Under normal circumstances, can be installed in any position on the pipeline, but to facilitate the test of operation, pay attention to the flow of media until the end of the vertical stainless steel elbow valve should flow upward, stainless steel elbow can only be installed horizontally. Stainless steel elbow in the installation should pay attention to sealing, to prevent the emergence of leakage, affecting the normal operation of the pipeline.
3, 304 / 304L, 316 / 316L, 310 / 310S Stainless Steel Butt Weld Elbow 45 degree 90 degree 180 degree ball valve, globe valve, gate valve use, only for full open or fully closed, do not agree to do to adjust the flow to avoid erosion of the sealing surface, accelerated wear and tear. Gate valve and the thread shut-off valve within the inverted seal device, the hand wheel screwed to the top position, you can prevent the media leak from the packing.
4, 304 / 304L, 316 / 316L, 310 / 310S Stainless Steel Butt Weld Elbow 45 degree 90 degree 180 degree hand wheel, do not use the lever or other tools, so as to avoid damage to the valve. Handwheel clockwise closed, on the contrary is open. Sub-ah use justice, to ensure accurate use of methods and means.
5, 304 / 304L, 316 / 316L, 310 / 310S Stainless Steel Butt Weld Elbow 45 degree 90 degree 180 degree valve packing gland bolts should be tightened evenly, should not be pressed into a crooked state, so as to avoid bumps hinder stem movement or cause leakage.
6, 304 / 304L, 316 / 316L, 310 / 310S Stainless Steel Butt Weld Elbow 45 degree 90 degree 180 degree in the use of the process, should always be kept clean, the transmission screw lubrication must be regular, found that failure should be immediately discontinued to find out the reasons to clear the fault

Where to find 304 / 304L, 316 / 316L, 310 / 310S Stainless Steel Butt Weld Elbow 45 ° 90 ° 180 ° ?
