During the construction of hot-dip SA588 Grade K atmospheric corrosion resistant structural steel galvanized pipe, the correct welding process shall be adopted, the inspection and acceptance shall be carried out in strict accordance with the specification, and the anti-corrosion treatment (zinc rich paint) shall be done timely after the welding is completed. It is feasible in the construction process of open and closed air conditioning system, which can improve the SA588 Grade K atmospheric corrosion resistant structural steel construction speed and the firmness of the pipe connection. Therefore, the hot-dip galvanized pipe can be welded and connected under the construction conditions and on the premise of relevant protection and anti-corrosion measures.
09CuPCrNi-A weather-resistant steel plate is one of weather-resistant steel (that is, atmospheric corrosion-resistant steel), used in sulfur-containing flue gas, air preheater, economizer, boiler air preheater, to prevent the vicinity of acid dew point, etc. Commonly used is low temperature weathering steel, which has a strong ability to resist low temperature corrosion. This type of steel SA588 Grade K atmospheric corrosion resistant structural steel has a protective effect against corrosion.
How to distinguish the inferior steel plate? 1. The surface of the fake and inferior steel plate is easy to produce scab. 2. The material of fake and inferior steel plate is not uniform and there are many impurities. The surface of fake and inferior steel plate is often pitted. Pitting is an irregular and uneven defect on the surface of SA588 Grade K atmospheric corrosion resistant structural steel, steel plate caused by serious wear of rolling groove. Due to the pursuit of profit by the manufacturers of fake and inferior steel plates, the groove rolling often exceeds the standard.
