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.

Analysis of the industry, the main reasons for the growth of Tianjin Port's oil drilling equipment exports:
First, China has gradually become an oil drilling equipment manufacturing base and has a price advantage. At present, China can export more advanced sets of more than 6,000 meters of variable frequency drive rigs and car-mounted drilling rigs that are adapted to polar temperatures of minus 60 degrees Celsius. In addition to the low labor cost in China, the price advantage in the international market is obvious. Taking export bulk products such as drill bits, solid pressure equipment, and drilling accessories as an example, China’s average is about 30% lower than similar foreign products, and some are even about half lower. In recent years, the production capacity of the international petrochemical general machinery manufacturing industry has gradually shifted to China. Enterprises in developed countries have outsourced their equipment production to China, and their production scale has continuously expanded.
The second is that the national policy promotes the progress of production technology. Since the late 1990s, the relevant authorities of the state have revised the industry standards for oil and gas drilling equipment, and have successively developed more than 20 varieties of oil and gas drilling machines to standardize the oil and gas drilling equipment in China. Breakthrough progress has been made in the level, manufacturing and research and development capabilities. AC frequency conversion speed-controlled electric drive oil drilling rigs and other products have reached the international advanced level in the same period, and have been recognized by users in the international market. In the “Eleventh Five-Year Plan†of the National Development and Reform Commission, the oil and gas exploration and drilling equipment manufacturing industry is also regarded as one of the industries, products, and technology directories that have been encouraged to develop, and the government has given preferential policies to encourage development.
The third is to expand the market through international operations. After the internationalization of China's petroleum industry, after the development in the mid to late 1990s, it has now shifted from the development of low-risk single-field oilfields to the development of oilfield production and technical services, refinery construction, and pipeline construction. This has resulted in the formation of North Africa and Central Asia - Four strategic development zones in Russia, South America and South Asia. By the end of 2006, China's oil companies had signed more than 40 oil contract projects with more than 30 countries. Internationalized operations have begun to take shape and have driven oil drilling equipment to the international market.
From January to April this year, the Tianjin port exported 1,149 sets of oil drilling equipment to the United States, an increase of 44.8%, which accounted for 71.8% of the total export volume of oil drilling equipment at the Tianjin Port during the same period. In addition, the Tianjin port exported 427 oil drilling rigs to Canada, which was basically the same as the same period of last year. Exports to India were 37, while only 2 were exported during the same period last year.

China has become an oil drilling equipment manufacturing base
With the encouragement of national policies, China's oil drilling equipment manufacturing technology has become increasingly mature, and gradually become a petroleum drilling equipment manufacturing base, which promotes the substantial growth of equipment exports. According to the statistics of Tianjin Customs, 1,734 oil drilling equipments were exported from Tianjin ports in January-April 2007, an increase of 16.9% compared with the same period of last year.
