Threaded Flange is a flange that connects threads to pipes. When it is designed, it can be treated by a loose flange. The advantage is that there is no need for welding, and the additional torque on the cylinder or pipe when the flange is deformed is very small. The disadvantage is that the thickness of the flange is large and the cost is high. It is suitable for the connection of high pressure pipe.
The threaded flange is made from the inner hole of the flange into pipe thread and connected with the pipe with thread, which is a non welded flange. Compared with the flat welding flange or butt welding flange, the threaded flange has the characteristics of convenient installation and maintenance, and can be used on some pipelines which are not allowed to be welded on the spot. Alloy steel flanges are of sufficient strength, but they are not easy to weld or have poor weldability. Threaded flanges can also be selected. However, if the temperature changes rapidly or the temperature is higher than 260 C below -45 C, it is recommended not to use threaded flange to avoid leakage.

China has nearly 3 million square kilometers of jurisdictional seas. These "blue lands" are huge treasure troves of resources and can provide more than 20% of oil and gas, about 70% of raw salt, and can also provide abundant coastal cities and towns with a population of several hundred million each year. Industrial water and domestic water. In addition, seawater, which is the largest mineral resource pool on the earth, also contains a large amount of important chemical elements such as magnesium, potassium, bromine, lithium, uranium, and thorium. Currently, seawater has been found to contain as many as 80 humans. Kind of chemical element.
The just-released "China Ocean Development Report" shows that by 2010 China's domestic marine crude oil production will exceed 50 million tons. The "Special Plan for the Utilization of Seawater" issued by the relevant authorities proposed that by 2010 China's seawater desalination capacity will reach 800,000 to 1 million cubic meters per day, and seawater direct utilization capacity will reach 55 billion cubic meters per year, actively developing seawater chemical resources. The comprehensive utilization of seawater utilization has contributed to 16% to 24% of the contribution to the problem of water shortage in coastal areas.
At present, the world is facing the problem of resource depletion and energy shortage. The ocean will become an important support for human survival and development. For our country with a large population, a serious lack of water resources, and resources and energy bottlenecks, the development and utilization of marine resources is more far-reaching.
