 According to different production methods, seamless pipes (smls pipe) can be divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, and extruded pipes.Since seamless pipes are often in high temperature and high pressure conditions when they are used, seamless pipes are mainly used to make superheater tubes, reheater tubes, steam guide tubes, and main steam seamless tubes for high pressure and ultra-high pressure boilers. 1. Hot-rolled seamless tubes are generally produced on automatic tube rolling mills. The solid tube is inspected and cleaned of surface defects, cut to the required length, centered on the perforated end of the tube, and then sent to the heating furnace to be heated and pierced on the piercing machine. When the perforation continues to rotate and advance at the same time, under the action of the roller and the plug, a cavity is gradually formed inside the tube blank, which is called a capillary tube. And then sent to the automatic rolling mill to cont...

Common forging machines are rotary, link and roller. 　　2. Roller method: Place the core in the stainless steel tube, and use the roller to push the outside to process the round edge. 　　3. Stamping method: Use a tapered core to expand the pipe ...

 　　The downstream demand gradually recovered, the demand increased slightly, the activity of port traders increased, and the inquiries increased, which boosted the port coal price, and there was a jump of about 10 yuan/ton per day. 　　From the perspective of the number of ships, the anchor ships of the major coal ports in the Bohai Rim remain low, and actual demand and transactions at the ports are not much; in the Bohai Rim ports, the trading atmosphere of middlemen is active, while the terminal power plants are generally motivated. The main downstream power plants are not low in inventory, and the coal companies that pull the market are mainly chemical, cement and other companies, as well as traders who inquire about goods. Consignors with coal are reluctant to sell their goods, and high-calorie and low-sulfur coal is once again structurally tense; today, the coal price of 5,500 kcal is 630 yuan/ton, which is much higher than the index quotation, prompting a jump in coal prices. O...

 　　Beginning last week (March 1-7, the same below), with the acceleration of industrial enterprises’ resumption of work and increased demand for hedging coal at superimposed ports, power plants have entered the contract fulfillment period in March. The overall market activity has increased compared with the previous period. After the continuous decline, the price stabilized, stopped falling, and rose. From Wednesday to Friday, there was a daily jump of 10 yuan/ton. With the decline in demand and fewer anchored ships, it is expected that the increase in coal prices will narrow this week. 　　Beginning last Monday, the daily consumption of power plants has increased significantly, end-user inventories have declined slightly, the market has seen a watershed, and purchasing demand has increased; superimposed futures premiums have risen sharply, and the demand for spot selling in some parts of the market has also increased significantly, driving the rapid increase in coal prices in the po...

 　　1. In order to prevent the corrosion between the eyes due to the heating of the flange cover, the welding current should not be too large, the arc should not be too long, the interlayer cooling is fast, and the narrow weld bead is suitable. 　　2. The electrode should be kept dry when used to prevent the electrode from sticking to oil and other dirt, so as not to cause the weld to increase the carbon content and affect the quality of the weldment. 　　3. When welding stainless steel flanges, the carbide is precipitated by repeated heating, which reduces the corrosion resistance and mechanical properties. 　　4. If the weldment cannot be heat-treated after welding, stainless steel flange pipe electrode should be used. 　　5. In order to improve the corrosion resistance and weld-ability, an appropriate amount of stability elements is added appropriately, and the weld-ability is better than that of chrome stainless steel flanges. 　　The above is a brief introduction to the use of stainless ...
