Analysis of fault layer problem of S690QL steel equivalent to grade 50

There are several grades of ferritic steel covered by A333 seamless and welded carbon and alloy steel pipe standard: Grade, Grade 3, Grade 4, Grade 6, Grade 7, Grade 8, Grade 9, Grade 10 and Grade 11. BBNsteel company provides ASTM A333 pipes made by the seamless or welded process with the addition of no filler metal in the welding operation except that Grade 4 shall be made only by seamless process. The pipe S690QL steel equivalent to grade 50 shall be furnished free of welding repair, either radiographically tested or ultrasonically examined.

Non-destructive flaw detection of steel plates is a test method for inspecting the S690QL steel equivalent to grade 50 surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used S690QL steel equivalent to grade 50 steel plate flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetration flaw detection, eddy current flaw detection, gamma-ray flaw detection, fluorescent flaw detection, color flaw detection and other methods. Physical flaw detection is non-destructive flaw detection without any chemical changes.

S690QL steel equivalent to grade 50, ASTM A302 Grade B/A302 Gr.B vessel plates boiler steel sheets are manganese-molybdeum-nickel alloy steel plates, which are widely used in petroleum, chemical industry, power station, boiler, etc, to make the reactor, heat exchanger, separator, spherical tank, liquefied gas, nuclear reactor pressure vessel, boiler steam drum steam, liquefied petroleum, hydropower station and so on.

First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers".
