S690QL heat treatment standard and specificaiton

Steel S690QL heat treatment exports fell sharply year on year. According to the data of the General Administration of customs, 7.811 million tons of steel were exported from January to February, a year-on-year decrease of 27.0%; 2.041 million tons of imported steel, a year-on-year increase of 2.1%. Steel prices continue to fall. According to the monitoring of China Iron and Steel Industry Association, China's steel S690QL heat treatment composite price index at the end of January was 105.48 points, down 0.58% month on month; at the end of February, the index continued to decline to 100.39 points, down 4.83% month on month.

Our company is a specialized technical support and after-sales service organization - customer service center. At the same time, we have provided excellent technical S690QL heat treatment personnel and strong technical support for our company, and cultivated an excellent after-sales team for our company. Our company will appoint a full-time service manager to be responsible for the unified coordination of technical support and S690QL heat treatment after-sales service of the project.

Pipeline steel refers to a type of steel with special requirements used for the transportation of oil, natural gas and other pipelines. Depending on the thickness and subsequent formation, pipeline steel can be produced by hot continuous rolling machines, furnace coil machines or plate machines, and formed into large-diameter steel pipe by spiral welding or UOE straight seam welding. The current development trend of S690QL heat treatment pipeline engineering is large-diameter, high-pressure rich gas transportation, high cold and corrosive service environment, and thickening of submarine pipelines.

Main S690QL heat treatment production plants: Wugang, Baosteel, Laiwu Steel, Angang, Baotou Steel, BBN Steel, Katalor Industry
Pressure vessel plates are used to manufacture steel plates for steam boilers, pressure vessels and other pressure vessel structures. Because this kind of steel plate is subjected to certain air pressure and water pressure, and the use environment of different temperatures, such as high, medium and low temperature, etc., the requirements for this kind of steel plate are relatively strict.

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 S690QL heat treatment 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.

We have huge stocks for carbon steel plates, high strength low alloy steel materials, weather resistant steel sheets, wear resistant steel plates, boiler plates, pipeline steel, etc. Those stocks can be delivered within 10 days after deposit. We update S690QL heat treatment stock list regularly. But the stock changes quickly. It needs to check with warehouse specially when you have urgent needs. Welcome to contact us and book steel materials stocks.
