Welded steel pipe is made of steel belt or steel plate and bended into deformation shapes such as round, square and so on, whose surface is jointed. Since the 30s of last century, with the rapid development of high-quality strip steel rolling production and technology of welding and inspection, welding quality improves constantly. Welded steel pipe was developed with increasing specifications and replaced seamless steel tube in more and more fields because welded steel pipe has lower cost and higher production efficiency.
Statistics in Production and Marketing Demand and Investment Forecast Analysis Report of China Welded Steel Pipe in 2014-2018 released by Forward-looking Industry Research Institute showed that the welded steel pipe output in Tianjin was 1.326 million tons in October 2013, increasing by 7.10% compared with last year earlier. The welded steel pipe production in Hebei was 1.081 million tons, increasing by 6.40% than a year earlier. The welded steel pipe output in Tianjin and Hebei reached 23.176 million tons from January 1, 2013, to October 1, 2013. The two places produce large amount of welded steel pipe in China.
Forward-looking Industry Research Institute analyses that the demand market of welded steel pipe industry in China is oil and gas exploitation and transportation, water, water conservancy construction, metal pressure vessel, construction steel structure, etc., in which oil and gas exploitation and transportation is the main demand market.
The total length of the second line of West-East natural gas transmission project, for example, is 9035 kilometers. The application amount of welded steel pipe is 4.326 million tons, in other words, the average application amount of welded steel pipe is 478.8 tons per kilometer. China will strive to develop the oil and gas pipeline during the 12th Five-Year Plan period. The government has clearly put forward in the 12th Five-Year Plan outline that they will set in the construction of the second phrase of oil pipeline between China and Kazakhstan, the territory passage of China and Myanmar oil, the second phrase of central Asia gas pipeline, the third line and the fourth line of West-East natural gas transmission project and other backbone engineering. They will build the suitable lines and a complete set of regional and urban pipe network. The total length of oil and gas pipelines will exceed 150000 km until 2015.
Under the relevant development planning, it faces better development prospects for oil and gas pipe network, coal-gas pipeline, deep sea oil and gas pipeline, etc in the future, effectively promoting the development of welded steel pipe industry in China.
