Advantages of polyurethane insulation pipe

1. This kind of pipe has good thermal insulation performance, and the heat loss is very small during the transportation process, which is only one-fourth of that of traditional pipes compared with traditional pipes. In this way, long-term use of this energy-saving pipeline can save a lot of energy. 　　2. This kind of pipeline construction is very convenient, that is, the overall cost is relatively low, and it has strong corrosion resistance and impact resistance. 　　 3. Polyurethane insulation pipe has a particularly long service life. 　　4. Because of the particularity of polyurethane insulation pipes, in the production process, the production cost of polyurethane insulation pipes is very low, which leads to the price of polyurethane is also very suitable. During installation, if polyurethane insulation pipes are used, a lot of installation costs can be saved. related suggestion

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

There are many problems in the use and maintenance of stainless steel elbows, which require users to use them in a certain way, and use and maintain them in an accurate and fair manner. The considerations are as follows: 　　1. Stainless steel elbows stored for a long time should be checked in time, and the exposed surface should be kept clean, dirt removed, and stored neatly in a ventilated and dry place indoors. Stacking or open storage is strictly prohibited. Stainless steel elbows are always kept dry and breathable, and the holder is clean and tidy, and stored in accordance with accurate storage methods.   2. During installation, the stainless steel elbow can be directly installed on the pipeline according to the connection method, and the stainless steel elbow can be installed according to the location of use. Under normal circumstances, it can be installed in any position of the pipeline, but it requires easy-to-operate inspection. Note that the flow of the stainless steel elbow medium should flow under the longitudinal valve flap, and the stainless steel elbow can only be installed horizontally. When installing the stainless steel elbow, pay attention to sealing to prevent leakage and affect the normal operation of the pipeline. 3. When using stainless steel elbow ball valves, globe valves and gate valves, they can only be opened or closed, and the flow rate must not be adjusted to avoid wear of the sealing surface. The gate valve and the upper threaded globe valve are equipped with an inverted sealing device, and the handwheel is fastened to the top to prevent media Leakage from the filling point. 　　 4. Use the hand wheel to make stainless steel elbows. Do not use levers or other tools to avoid damage to valve components. Turn the handwheel clockwise to close, and vice versa. When using, we should be fair and ensure the correct use of methods and means. 　　5. The bolts of the stainless steel elbow valve packing cover should be evenly tightened, and should not be pressed into a bent state, so as not to interfere with the movement of the valve stem or cause leakage. 　　 6. The stainless steel elbow should be kept clean during use, and the transmission thread must be lubricated in time. Once a fault is found, it should be stopped immediately to find out the cause of the fault.
