On April 13, 2016, Hunan Hualing Hengyang Steel Pipe (Group) Co., Ltd. produced 110 tons of 769 IPD marine engineering pipelines X65QOΦ114.3*4.77mm produced by a foreign company in the pipe processing plant 3# line heat treatment once Sexual success, successfully passed the rigorous test.
It is reported that this is the first time that Hengyang Hualing has produced such a thin line pipe for marine engineering. The average length of the pipe is more than 12.2 meters. The production is extremely difficult. It is difficult to control the dimensional accuracy of hot rolling, and the high temperature during heat treatment. The dimensional accuracy caused by the easy deformation is deteriorated, the bending is excessively poor, and the mechanical properties are difficult to control.
In order to ensure the smooth production of this contract, the 180 branch factory, pipe processing branch and technical center have optimized the composition from component design, heat treatment to final straightening process, tracking key processes to ensure process execution. In place.
In the end, this contract was successfully produced once, and the geometrical dimensions and mechanical properties were controlled within the appropriate range. This production not only broadens the product range of Hengyang Hualing high-quality offshore engineering pipe, but also enables Hengyang Hualing technicians to further accumulate experience in the production and tempering heat treatment of high-grade thin-walled pipes, and to follow the high-end offshore pipe market. The development laid a good foundation.
Double Iridium Spark Plug
Our company was set up in 2002.We are using the advanced cold punch technology to produce spark plug which is similar to NGK and Champion technology.With such technology, the metal shell and ceramic are better protected the quality of the spark plug are more stable to get avoid from air leaking and broken.Our spark plug products are ranged into more than 100 models with an anual out put of 6 million pcs. Besides the advanced technology,we also have a strong advantage of automatical production.Most of our production device is automatical that we have very high,efficiency and stable quality.Throughout such years of developing,we have gained a good reputation at domestic motorcycle manufacturer.Furthermore,our products have been exported to South East Asia, Middle East, Australia and so on. Revolution,refine and devotion are our principal of working.Welcome to visit us and raise your demand and your comments request are our target to strive.
