What is a 45 degree pipe elbow used for?
A 45 degree elbow is the elbow which can change the flow direction in a 45 degree . As a joint, it is used between the two pipes which has this right angle. In the field of butt welding steel elbows, it looks like a half of the 90 degree elbow.
Why is it called Street 90?
