Bend and elbow the most basic difference is that the elbow is relatively short. R=1 times to 2 times the elbow, and then a large multiples of the bend. In the production process of cold bend can be readily used straight pipe with a straight pipe bending machine, a one-time completion of the two anti-corrosion. But the elbow to the manufacturers custom, to do anti-corrosion, long order cycle. Elbow price than the bend to high but the price is than the bend to a much higher, without doing anticorrosion treatment bend is easy to damage is well-known, but because of cheap price in some of the requirements are not very high engineering use very much. ..
