Stainless steel flange   designs the flange body and the socket as an integral structure, which avoids leakage due to the inability to align the welding port during welding and have a good sealing performance. The methods to deal with rust on stainless steel flanges: 1. Clean with emery cloth and wire brush. 2. Using a tungsten steel shovel to shovel away large areas of rust. 3. Using a file to remove welding slag and other protrusions and various burrs. 4. Using a scraper and a wire brush to remove the rust on the corners. 5. Using a clean cloth, or a cloth dipped in solvent to clean and apply primer in time. 6. Note that the toughness coating film that has not expired can be retained, and the surface of the old paint should be roughened with emery cloth, and the defect of the coating film should be polished into an axe shape, and the paint should be painted directly after cleaning.

Carbon steel elbow  is used to change the direction of the pipeline on the carbon steel pipe. There are threaded connection and welded connection. According to the angle, there are 45° and 90°180°.   here we briefly describe the application of carbon steel elbows: (1) It not need to take tube blanks as raw materials, which can save the cost of tube-making equipment and molds, and can obtain arbitrarily large diameter and thin carbon steel elbows. (2) Short the manufacturing cycle, which greatly reduced the production cost. And it does not require any special equipment that make it able to do on-site processing for large carbon steel elbows. 　　 (3) The blank is a flat plate or a developable curved surface, so the blanking is simple, the accuracy is easy to guarantee, and the assembly and welding are convenient. 　　 (4) Carbon steel elbows are good for pipeline series in petroleum, gas, chemical, hydropower, construction and boiler industries etc.
