What should be paid attention to in the maintenance of stainless steel elbows

What should be paid attention to in the maintenance of stainless steel elbows? There are many things to pay attention to when using and maintaining stainless steel elbows. Users need to use them in a certain way, and use and maintain them in an accurate and fair way. Notes are as follows: 1. Stainless steel elbows stored for a long time should be inspected regularly, and the exposed processing surfaces should be kept clean, cleaned of dirt, and neatly stored in a ventilated and dry place indoors. It is strictly forbidden to store them in the open air. Always keep the stainless steel elbow dry and ventilated, keep the device clean and tidy, and store it according to the accurate storage method. 2. When installing, the stainless steel elbow can be directly installed on the pipeline according to the connection method, and installed according to the position of use. Under normal circumstances, it can be installed at any position of the pipeline, but it needs to be checked for easy operation. Note that the medium flow direction of the cut-off stainless steel elbow should be from the bottom of the vertical valve disc to the upper flow, and the stainless steel elbow can only be installed horizontally. When installing stainless steel elbows, pay attention to the tightness to prevent leakage and affect the normal operation of the pipeline. 3. When the ball valve, globe valve and gate valve of stainless steel elbow are used, they are only fully open or fully closed, and are not allowed to be used to adjust the flow, so as to avoid erosion of the sealing surface and accelerated wear. There are inverted sealing devices in the gate valve and the upper threaded globe valve. The handwheel is turned to the upper position and tightened to prevent the medium from leaking from the packing. 4. Handwheel should be used for stainless steel elbow, please do not use lever or other tools to avoid damage to valve parts. Turn the handwheel clockwise to close, and vice versa to open. Ziah should be fair when using it, and ensure accurate use methods and means. 5. The bolts of the stainless steel elbow valve packing gland should be tightened evenly, and should not be pressed into a crooked state, so as to avoid bumps that hinder the movement of the valve stem or cause leakage. 6. The stainless steel elbow should always be kept clean during use, and the transmission thread must be lubricated on schedule. When a fault is found, it should be stopped immediately, and the cause should be identified to clear the fault.

What is the allowable error of the standard wall thickness of malleable steel pipe fittings?

Malleable cast iron pipe fittings are produced according to GB/T3287-2011 "Malgeable cast iron pipe fittings". The GB/T 3287-2011 standard is the second Chinese national standard set in July 2009. When the standard was revised, the international standard ISO49: 1994 "Moldable Iron Pipe Fittings with ISO 7-1 Thread" and the European Standard EN 10242: 1994/A2: 2003 "Malgeable Iron Threaded Pipe Fittings" were adopted, which are equivalent to the above two advanced foreign standards. 1. The mechanical properties of the pipe fittings are tensile strength ≥330MPa; elongation ≥8%, which is better than the malleable cast iron of the KTH300-06 grade specified in GB/T9440-2010 "Moldable Iron Castings". 2. The structural dimensions of the pipe fittings conform to the provisions of Appendix A in the GB/T3287-2011 standard, and are consistent with the dimensions stipulated in the ISO49:1994 and EN 10242:1994/A2:2003 standards. 3. The thread of the pipe fitting adopts GB/T7306.1-2000 "55° Sealing Pipe Thread Part 1: Cylindrical Internal Thread and Conical External Thread" and GB/T7306.2-2000 "55° Sealing Pipe Thread Part 2: Conical Internal Threads and Tapered External Threads". It corresponds to the European Community pipe thread standards EN10226-1: 2004 (E) and EN10226-2: 2005 (E). It is the same as the pipe thread profile, size, tolerance and code specified in the international standard ISO7-1:1994. According to the national standards collected at present, all major industrial countries in the world except the United States, the European Community and most countries in the world have adopted the pipe thread standards stipulated by ISO7-1. Therefore, the threads specified in GB/T7306 are consistent with international standards, and can also be smoothly matched with the pipe threads of most countries in the world. 4. The hot-dip galvanized layer of the pipe fittings conforms to the requirements of GB/T3287-2011, ISO49:1994, EN10242:1994/A2:2003 and other standards. The quality of the surface zinc layer is not less than 500g/m2, the average thickness is 70μm, and the average thickness of individual samples is not less than 450g/m2, and the average thickness is 63μm.
