טבלת עמידות חומרים כימיים
הטבלה מציגה את התאמת החומרים הכימיים השונים לחומרי מבנה של משאבות ואטמים.
דירוגים: A – מתאים | B – מתאים חלקית | C – מוגבל / תלוי ריכוז | D – לא מתאים
* הנתונים מבוססים על עמידות חומרים בתנאי טמפרטורת סביבה (≈25°C) ולחץ אטמוספרי.
יש לקחת בחשבון כי ריכוזים גבוהים, טמפרטורות קיצון או תנאי לחץ עלולים להשפיע על התוצאות בפועל.
המידע נועד כהכוונה כללית בלבד ואינו מחליף בדיקה הנדסית ייעודית.
