The company specializes in the research and development, production and sales of ABS grade A monohull steel seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has ABS grade A monohull steel five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,ABS grade A monohull steel rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.
Facing the new situation and facing new goals, the company revolves around the sixteen-character development policy of “prioritizing production preservation, society-oriented, market operation, and brand creation and efficiency”. Layout the country in accordance with the modern logistics model, and accelerate the establishment of a modern integrated steel enterprise integrating steel storage, transportation, processing, and distribution.
Try to use ABS grade A monohull steel high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the ABS grade A monohull steel temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.
The Seamless Pipe Q345D to Thailand. In November of 2015, Thailand OTTO group contacted with us from Internet. They are finding the trustable supplier of S355/2H seamless pipe for the cable car supporter. Due to the special using of the pipes, they are very careful and serious when choosing the supplier. After one months contact and discussion by email, they come to our company. We drive to the pipe mill for visit of 2 days. Through this visit, they are very confident with our production ability and products quality. Finally, they accept the grade we suggest Q345D. After back to office, they put the order of 1800 tons pipe to us directly.
