130 years ago, the emergence of pipeline transportation had a profound impact on the development of the world economy. In the history of world pipeline construction, China’s long-distance pipeline construction has experienced a long process of development.

Dans 1958, the construction of the first long-distance pipeline Kedu Line entered a new development period. Up to now, China has built 395 long oil and gas pipelines, with a total length of 17000 kilometers. Pipeline transportation has played an important role in promoting the development of the national economy.

In the 1990s, new breakthroughs were made in the construction of long-distance pipelines in China. The construction speed of oil and gas long-distance pipelines was about 400 kilometers per year. A number of long-distance pipelines were built one after another, and the pipeline networks in Northeast, North and East China were gradually improved.

Long distance pipeline construction not only develops on land, but also extends to the sea and desert. In addition, the field of transmission medium is also expanding. The construction of offshore long distance pipeline is developed with the development and construction of offshore oil and gas fields.

In May 2012, Hebei Huayang Steel Pipe Co., Ltd. directly supplied 1500 tons of DN300-DN800 drinking water pipes to Islamabad Benazir Bhutto International Airport.
