Coating Defect Detection

Coating Defect Detection

In the protection of large structures such as bridges, storage tanks, and pipelines, coating systems act like a layer of "armor," effectively blocking external corrosion and extending the service life of the structure. However, if this "armor" has discontinuous defects such as pinholes or missed coatings, it becomes a "hidden entry point" for structural degradation—external oxygen and electrolytes can penetrate through these gaps to the substrate, causing corrosion of the metal base material and seriously affecting the safety and durability of the structure.

On-site Coating Engineer's List of Responsibilities

On-site Coating Engineer's List of Responsibilities

In industrial coating projects, the on-site coating engineer is the core role in ensuring coating quality. Their work spans the entire project cycle, from preliminary preparation to final acceptance, with every step affecting the coating's performance, lifespan, and project cost. Below are the detailed responsibilities and essential qualities of the on-site coating engineer.

How much do you know about fireproof coatings for steel structures?

How much do you know about fireproof coatings for steel structures?

Compensating for the fire resistance defects of steel structures: Although steel has high strength, it has strong thermal conductivity and easily heats up and softens when exposed to fire. Ordinary steel structures lose their load-bearing capacity in about 15 minutes during a fire, whereas fireproof coatings can form a protective layer through insulation or intumescent foaming, delaying the steel's temperature rise and buying time for evacuation and firefighting.

Corrosion protection: ISO 12944 standard from C1 to C5

Corrosion protection: ISO 12944 standard from C1 to C5

Corrosion is a phenomenon where materials (mainly metals) undergo chemical or electrochemical reactions with the surrounding environment, leading to performance degradation. In the fields of construction, industry, and marine engineering, corrosion prevention has always been a crucial topic. Whether it is towering steel structures or deep-sea marine facilities, corrosion issues can become sources of safety hazards.

Entering Sateri: Decoding the Excellence of the Company's Anti-Corrosion Engineering

Entering Sateri: Decoding the Excellence of the Company's Anti-Corrosion Engineering

On the road to pursuing excellent engineering quality, Jiangsu Chaohui Coating Engineering Co., Ltd. has always adhered to an open-minded and proactive attitude. Recently, the company's leadership personally led a team to the Chaohui Saiderli (Changzhou) project site to conduct a highly valuable learning and exchange activity. This learning focused on floor construction, acid-resistant brick anti-corrosion construction, and heavy anti-corrosion construction of acid-resistant granite, conducting a comprehensive and systematic in-depth exploration from the fine craftsmanship of anti-corrosion construction to the overall management methods of engineering.
