National Bureau of Statistics: The production of natural gas has grown relatively fast, and the daily average month-on-month has remained stable. From January to February, the production of natural gas was 34.8 billion cubic meters, a year-on-year increase of 13.5%, an increase of 22.5% over the first two months of 2019, and an average increase of 10.7% over the two years. The average daily output was 590 million cubic meters, a decrease of 10 million cubic meters compared to December of the previous year.

In the whole steel structure and steel body, the medium and heavy plate is an important part, once the problem occurs, it is easy to fracture, collapse and occur explosion. So how to judge whether the medium and heavy plate, a283 grade D thickness is of high quality? First of all, check whether there are cracks on the surface of the a283 grade D thickness plate and how glossy it is. Secondly, to measure the thickness error of medium and heavy plate, it is better to use the instrument to measure the bending tensile value. Finally, observe the scale of the steel plate manufacturers, whether there are relevant qualification certificates, and how the production process is.
