Dear K.Nikhom,
Refer to the attached photos, we found PSV (PSV-3058A/B, PSV-3049B) damage from sand blast and painted work that low quality performance and inconsistent to DeeLine procedure of surface preparation and painting control in paragraph 1.5.8, so please following the below details;
- TKIS allowed to sand blast and painted for manual valve only but TKIS not allowed to sand blast for PSV.
- Check how many of all painted valves and all damage valves
The problems of CE mark, tag valve data and all parts of valve have important for the handover and relate with time and cost increases, so you please inform how to solve the problem as soon as possible.
