With the development of multimodal transport in the international shipping market and the increase of the complexity of the integrated transport chain, modern ports, as the intersection of the three transportation modes of sea, land and air, are developing from traditional transfer and product distribution functions to all-round value-added services, becoming the central link connecting the world's production, exchange, distribution and consumption, and supporting the world economy and international trade An important part of the developed international circulation system.

A302 grade B pressure vessel steel sheet,Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.

In January, 2019, our South Africa customer purchased 669 tons S235J2+N carbon steel plates to use in their tank fabrication project S235J2 steel, as a non-alloy structural steel grade, is mainly used in structural projects and tanks J2 symbol -20 temperature impact test The client required CEV 038%, S≤001%, 100% UT, Charpy V-notch impact test at-20℃, Z25 for S235J2+N plates After they receiving the S235J2+N steel plates, the customer are very satisfied with the quality of this batch of products,A302 grade B pressure vessel steel sheet.
