China's welded pipe Tax ID fewer, more general, such as line pipe including a straight seam submerged steel pipe dimensions, straight seam high frequency welded pipe and spiral submerged arc welded pipe. In addition,the oil well casing pipe diameter range is very wide, from ф89mm to ф610mm. Steel pipe exports statistics show only line pipe exports, of which three kinds of tube type export the number does not show. Oil well pipe should be divided into a tubing and casing, casing should be according to the diameter of the group from the list a
single tariff lines.
In the classification of China's import and export customs statistics, import and export of welded statistics under the 7305 and 7306. In order to facilitate a
comparative analysis of the structure of export commodities, divided into four categories: the first category is the 7305 oil and gas pipelines, mainly refers to the
outside diameter greater than 406.4 mm for the transport of oil and gas and drilling pipe; second category is the large diameter longitudinally welded pipes under 7305
406.4 mm outside diameter greater than for other purposes; 7306 oil and gas pipelines under such smaller diameter oil and gas pipelines, there are some differences and
materials and 7305 oil and gas pipelines, including special Straight steel tube and pipe and tube catheter; 7306 under the fourth category for other purposes pipeline, this type of pipe outside diameter smaller or non-circular cross-section, involving a wide range of uses, low-tech. Of the four types of pipe, the first and third categories pipe is mainly used for pressure fluid transmission of oil and gas transportation, the production process requirements; the fourth pipe diameter smaller or Yixingguan the production process requirements are relatively low.
Related statistics show that China's welded pipe exports, first-class oil and gas pipelines and fourth pipeline is basically accounted for more than 90% of the total
exports of China's welded pipe. Changes in the proportion of these two categories of steel tube directly determine the trend of the commodity structure of China's welded pipe.
At present, China's Carbon Steel Pipesstructure of foreign trade is relatively simple, as the main way to export products, but mostly through intermediaries, directly few foreign customers. Another way, is built in the country of destination Steel Plant, so you can avoid the "double reverse". At present, China's steel enterprises have adopted this way, such as a tube of days in the United States to build seamless steel oil casing production line, Xuzhou halo Pipe Company in the United States built the pipe casing production line, pipe enterprises in Tianjin and Liaoning built in Vietnam, the Philippines, HFW pipe factory.
