In early 2004, Qingdao Haokun Heavy Machinery Technology Co., Ltd. was formally operated. At the beginning of the start, the product was designed and manufactured by the product of the steel pipe flat head and the static water pressure test machine. However, it soon undertook the full set of production lines of the domestic ERW610, and a gun was killed, thus establishing the position of the domestic steel pipe industry. Next, in 2007 and 2008, the ERW630 welded pipe units were designed and manufactured for domestic and foreign, and each set of crews made great technological progress compared to the previous.

Similarly, the domestic X80 high -steel SSAW1422 × 25.4mm spiral welding pipe crew was designed and manufactured by Hao Kun in 2007. After production, it attracted foreign orders due to good effect. The screw pipe unit was put into production as scheduled, winning the praise from the Malaysian oil industry.

Due to the "two -pronged approach" of straight seams and spirals, the business of Hao Kun has expanded rapidly. The annual output value of 2007 and 2008 exceeded 100 million yuan. On the basis of gaining benefits, Haokun has built a 13000m² plant and purchased various types of mechanical processing machine tools, which initially had the scale of processing and assembly.

In early 2009, 26 acres of land acquisition set up a R & D center. There are information intelligence rooms, direct sewing pipe research rooms, spiral tube research rooms, electrical hydraulic research rooms, cold curved steel research rooms, computer rooms, etc. The stress and strain of metal materials in the rolling process, the power parameters of the molding process, the cold -curved molding process, and the forming roller hole design are derived in depth, and then transformed into applicable technology The steel pipe production lines have continuously improved the level of steel pipe production in my country.

In the summer of 2009, Hao Kun levied 66 acres to prepare to build 14,400m² of modern industrial plant. In the factory, some of the welded pipe units independently developed by Hao Kun. On the one hand The production of steel pipes has continuously launched a new economic sectional steel industry chain to further improve the R & D -production -operation of one -stop model.

Over the past few years, Hao Kun has gone through the journey from starting to ultra -routine development. It not only achieved domestic units to update equipment domestic welding pipe companies, but also achieved the way out to develop an export -oriented economy, especially to cultivate a batch of batch of batch Excellent technical talents in the industry have created the Hao Kun team.

Hao Kun Company belongs to China and also belongs to the world. Hao Kun's tomorrow will be better.
