What is a large diameter elbow?

Large-diameter elbows, simply put, are pipe bends with a larger diameter, typically referring to elbows with a nominal diameter of DN300 and above. Some also include elbows with DN400, DN500, DN600, and even those exceeding 1000mm in diameter.

How to choose stainless steel elbow fittings?

First, determine the material flowing through the pipe. If the pressure in a general water plant pipeline is low, a straight seam elbow is more cost-effective. Straight seam elbows are made by pushing straight seam steel pipe. For high-temperature applications, seamless elbows are essential for better pressure resistance. If the pipe is used in chemical or corrosive equipment, stainless steel or alloy materials should be selected.
