At the "Second Asian Shale Gas Summit (Shanghai) 2012" held on the 17th, many experts at the conference said that the development potential of shale gas in China is huge, and it is necessary to further improve the shale gas utilization facilities such as layout pipe network and gas storage. infrastructure. Tan Zhaodong, executive chairman of Hong Kong Mingyuan Energy Co., Ltd. and chairman of the Independent Power Producers Association (IPPF), said that China's shale gas development should learn from the experience of US market operation, especially in the process of shale gas production acceleration. It is put into production, so it is necessary to lay out the construction of supporting facilities such as pipe network in advance. Tan Zhaodong said that if the transportation problem is not solved, China's shale gas project may be difficult to attract a wide range of investments. At present, China's oil and gas pipeline network is mainly controlled by large state-owned oil companies such as PetroChina. In the future, the government should encourage more social capital and private capital to participate in the construction of oil and gas pipeline networks. Jiang Xinmin, deputy director of the Energy Development and Development Strategy Research Center of the National Development and Reform Commission, also believes that China should further improve the construction of supporting infrastructure for shale gas utilization. First, in the shale gas exploration and development zone with relatively complete natural gas pipeline network facilities, actively construct gas field gathering and transportation pipelines and input shale gas into natural gas pipeline network. The second is to build a small LNG (liquefied natural gas) or CNG (compressed natural gas) utilization device for exploration and development areas that are far away from natural gas pipeline network facilities and have small gas storage output to prevent waste. Third, according to the progress of exploration and development, timely construction of shale gas pipelines.
Wire thread inserts are helically coiled fastening devices that provide permanent, wear-resistant screw threads that exceed the strength of most parent material; the inserts are designed to protect tapped holes against failures due to stripping, seizing, corrosion, and wear.
Threaded inserts are typically used when the object in which a threaded fastener is being installed is made of a soft material. For hard materials, a screw or bolt can be often driven into the object without the need for a threaded insert. A simple solution is to use a threaded insert.
