The company specializes in the research and development, production and sales of Sa573 grade 70 iron steel material chain 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 Sa573 grade 70 iron steel material chain five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,Sa573 grade 70 iron steel material chain rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.
Our company is located in the Central Plains, Zhengzhou City, convenient transportation. There is the largest Xinzheng airport, welcome customers from all over the world to visit our company. Our factories are all located near the port. The logistics is very convenient, which can save the delivery time.
Medium and high carbon alloy hot rolled plates are mainly used in cold rolling and calendering, saw blades and tool industries. The company has taken advantage of smelting, hot rolled Sa573 grade 70 iron steel material chain plate and coil finishing equipment and technical advantages, and has successfully developed a batch of high-carbon and its alloy steel and medium-carbon high-alloy Sa573 grade 70 iron steel material chain steel hot-rolled coils with the goal of replacing imports. The iron oxide scale is delivered and trusted by high-end users.
In April 8th, 2018, our Philiphine customer purchased 1008 Tons API 5L Gr.B ERW pipes &Q345B seamless steel pipe for offshore oildfield resources drilling project. This is a regular demand almost every two month, and we has been cooperated more than three times, totally around 2100 tons API 5L Gr.B steel pipeline since 2015 year. We can supply the relative certificated for the API 5L Gr.B ERW pipes products like SGS report, B/L &Form M, and mill test certificate.
