Energy market context, especially long distance gas pipeline construction to promote the development of large LSAW pipes, the current market, domestic and foreign markets in the domestic demand for oil and gas pipelines from about 8 million T, the supply amount of year 1100 million t, the more intense market competition, the future development trend of straight seam submerged arc welded pipe:

1, in terms of land-use tube, single-tube gas volume to reach 50 billion m3 / a level, diameter 1422mm, steel grade X80, gas pressure 12MPa.

2, in the ocean pipe connection, to develop deep-sea gas pipeline (depth of 1500m above) direction lines; marine structures to high-strength pipe, large wall thickness of the development, for example φ610mm × 31.8mm X65 steel grade specifications.

3, in business management, integrated tube plate (Steelmaking - Continuous Casting - rolled plate - pipe) is a trend, more than a pipe unit after accompanying strip production line in Japan, India, China's Baoshan Iron and Steel Co., Ltd., Zhangjiagang Shagang Jinzhou pipeline Co., Tangshan Iron and steel Group Co., Ltd. etc. so.

4, high-grade structural tube to enter the market. An important problem of LSAW pipe enterprises in the construction of the production line equipment configuration to be considered as an important issue when you set the configuration to be considered before the expected welding, such as preheating before the expected welding equipment, heat-treated or disposed step is necessary; at the same time, the gradual introduction of network and information management.

5, in marketing, in addition to oil and gas, there are slurry transportation; mechanical structure tube, they shall be extended to use in the field of thermal power, nuclear power, hydropower, power, shipbuilding, chemical and other pipes, and pay attention to product diversification Personalise.

6, and the development of anti HIC Resistance to deformation tube, the ability to adapt and enhance the delivery of acidic gas pipe in adverse geological conditions (landslides, mudslides, earthquakes) case against external environmental damage.
