نحوه محاسبه ضخامت و قطر داخلی و خارجی لوله
لوله استوانه ای توخالی است که از آن برای انتقال یا نگهداری سایر مواد و مایعات استفاده می کنند. لوله ها می توانند از مواد مختلفی مثل آهن ، فولاد ، پلیمر ، شیشه و غیره ساخته شوند.از انواع اوله میتوان به لوله های فلزی و لوله های پلی اتیلنی که کاربرد فراوانی دارند اشاره نمود.
