Dobavljač cijevi od nehrđajućeg čelika Wenzhou Kaixin Kina
An elbow is the pipe fittings that are used extensively as a form of connections in between two lengths of pipes for the purpose of producing the change into the flow direction into the pipe, at the angle of 180 deg, 90 deg or 45 deg. Elbow pipe fitting is also called as the bend that is available in the ranges of materials including alloy steel, carbon steel, nerđajući čelik, nickel alloy, super duplex, duplex, and cupro-nickel, itd. 180° Long Radius Elbow is also termed as the return bend that permits the complete reversal of the flow. The distance in between the center line and end of the elbow is 3 x NPS.
Some qualities of it are High mechanical strength rugged construction, Smoothness in surface finishes, Perfect dimensional accuracy, Anti-corrosive body, and Pitting and oxidation resistance.
