Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the ASTM A573 structural steel plate 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 ASTM A573 structural steel plate 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.
The company is based on the principle of good faith, small profits and quick sales, and keeps forging ahead.
