Does API standard 650 self-anchored flat-bottom steel tanks have good toughness

BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of API standard 650 self-anchored flat-bottom steel tanks steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main API standard 650 self-anchored flat-bottom steel tanks production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.

Ningbo port has trade and transportation with more than 50 countries and regions, such as the United States, CIS countries, Europe, Africa, Japan and South Korea, Southeast Asia, the Middle East and Hong Kong. Ningbo port has initially formed an all-round three-dimensional collection and distribution network of expressways, railways, aviation, river sea intermodal transport, water to water transfer, etc.

S355J2 steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the API standard 650 self-anchored flat-bottom steel tanks rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of API standard 650 self-anchored flat-bottom steel tanks steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.

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 API standard 650 self-anchored flat-bottom steel tanks 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.

Q355B steel and API standard 650 self-anchored flat-bottom steel tanks steel
Both Q345B and Q355B are low alloy steels. The difference is that the yield strength of Q345B low alloy steel and Q345B low alloy steel is different. In Q345B low-alloy steel, q represents the yield strength of this material, and the latter 345 represents the yield value of this material is around 345mpa. Q in Q355B low-alloy steel also represents the yield strength of this material, and the latter 355 indicates that the yield value of this material is around 355mpa.
