The production process of S550QL stahl

Ultrasonic flaw detection emits ultrasonic waves to the S550QL stahl steel plate under inspection. If there are defects in the steel plate, the ultrasonic waves will reflect, refract or deform waveforms due to the defects. By recording these changes, the type and shape of the defects are analyzed. Due to its high energy and good penetration performance, and the smoothness of the S550QL stahl steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.

For S550QL stahl ASTM A106 seamless steel pipe could transport fluids or gasses at high temperature and pressure levels, with 3 grades A, B, C, most common used ASTM A106 Grade B S550QL stahl is widely used in the projects of oil and gas refineries, power plants, petrochemical plants, boilers.

The technology center has always been focusing on application research, improving market realization and scientific and technological contribution rate; taking user demand as the goal, highlighting the personalized development of products; taking the joint development of industry, University and research, and technology integration as the means, improving the starting point and level of innovation, and realizing the breakthrough of core technology; taking advanced research as the guide, pursuing the leap of technological development; taking system and mechanism innovation as the driving force, Promote and realize the working concept of technological innovation.

The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the S550QL stahl principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.

we develop very well through those years even the external environment is not conducive to the whole steel industry. With the prosperity of our group, our company always bear its staff who contributes to its growth in mind, and always on the way to improve welfare and treatment. That makes us staff and work with pleasure. On the other way, they creat a better and stronger our group. That may be one of the key factors why we develop so rapidly those years. Here we can say proudly “we are family”.

As leading EN10025-6 S460QL structural steel plates supplier in China, our company has supplied hundreds of thousands tons S460QL steel plates to clients to assist them finish one after another S550QL stahl magnificent projects.
