استاندارد بازرسی پایپینگ برای خطوط تحت سرویس ، تعمیرات، و جایگزینی سیستمهای پایپینگ

Piping Inspection Code: In-service Inspection, Rating, Repair, and Alteration of Piping Systems

API 570 بدون شک، یکی از کاربردی ترین و مهمترین مراجع استاندارد واحدهای پایپینگ، و بخصوص سیستمهای لوله کشی که تحت سرویس (In-Service) هستند میباشد.

این استاندارد نکات فنی و ملزومات تعمیرات و جایگزینی صحیح سیستمهای پایپینگ را ارائه میدهد.
