The company specializes in the research and development, production and sales of A709 grade 50W low alloy 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 A709 grade 50W low alloy steel five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,A709 grade 50W low alloy steel rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.
The full name of 304 stainless steel pipe is SUS304 stainless steel pipe. SUS304 stainless steel pipe belongs to the stainless steel pipe made of American trademark. It is equivalent to Chinese grade 0Cr19Ni9 stainless steel pipe, which is generally replaced by 0Cr18Ni9. The mechanism of stainless steel rust prevention is that the alloy elements form a fine oxide film, which insulates the touch of oxygen and prevents continued oxidation.
Alloy steel seamless pipe is a kind of high-quality seamless steel pipe with outstanding performance and characteristics. The alloy steel seamless pipe has excellent high-pressure resistance and can withstand greater pressure. Even under pressure, the A709 grade 50W low alloy steel, alloy steel seamless pipe is not easy to break, and it is more safe and reliable to use. It also reduces the loss of pipe material and reduces the maintenance work of pipeline.
How to distinguish the inferior steel plate? 1. The surface of the fake and inferior steel plate is easy to produce scab. 2. The material of fake and inferior steel plate is not uniform and there are many impurities. The surface of fake and inferior steel plate is often pitted. Pitting is an irregular and uneven defect on the surface of A709 grade 50W low alloy steel, steel plate caused by serious wear of rolling groove. Due to the pursuit of profit by the manufacturers of fake and inferior steel plates, the groove rolling often exceeds the standard.
