Welcome to BBN High Strength Steels Factory
The company adheres to the management concept of "people-oriented, talent is concerned", develops business with the spirit of "believing strength, practical style, material S620QL professional service and dare to compete", and provides customers with "professional, value-added and effective" service support. For the company's development and take-off, we work together to move forward and create a better material S620QL tomorrow!
As we all know, steel pipes occupy more space in the process of transportation. If there is no good way of packing, the transportation cost for steel pipes will be a big expense. In view of this characteristic, our company is ingenious and adopts the nest package method to solve this problem perfectly. The premise of the nest package is that the diameters of the steel pipes are different, and the small diameter pipe is inserted in the large diameter pipe. This not only saves the volume, but also saves the transportation cost. It also reduces the loading and unloading workload by half, saves precious time, and enables customers to receive goods earlier.
Quenching is a common heat treatment process. It is the metal heat treatment process in which the material S620QL metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between material S620QL strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
We cooperated with the Peruvian government for many years. And supply them large diameter steel pipes and pipe fittings to support their Hydropower Station Projects. We do 100% UT, RT, Hydraulic test and so on tests for the material S620QL steel pipes. And do PT, MT and so on tests for the pipe fittings. We published "Welding Procedure Qualification report" after production. And our mill will keep the test record in the documentary department for 5 years. If meet any problems in following application, we can check the test record easily and assist to solve problems at the first time.
There are a lot of ASTM standards for pressure vessel steel plates. Such as ASTM A204, A285, A302, A387, A515, A516, A517, A537, A612, A841, etc. Those ASTM steel plates have different thickness ranges. material S620QL, ASTM A204 plates shall not thicker than 150mm. ASTM A285 plates shall not thicker than 50mm. ASTM A515 plates shall not thicker than 200mm. ASTM A517 plates and A537 plates shall not thicker than 150mm. ASTM A612 plates shall not thicker than 25mm. ASTM A841 plates shall not thicker than 100mm.
Our company was founded in 2009, and has been committed to steel business since its establishment. Over the years, the company's performance shows a good development trend, with a wide range of customers in the government, domestic and foreign markets. The company has always been in line with the tenet of "based on trust and win with quality", focusing on the market demand, with a long-term vision, with years of hard work and trustworthy operation, and the support of the majority of material S620QL businesses and customers, has won the unanimous praise and trust of the industry and customers!
