AL-6XN® Alloy Elbows
With a variety of options to choose from, Central States Industrial (CSI) will help you find the elbow you need.
AL-6XN® elbows are available in 90º, 88°, 92°, and 45º options. You have a choice of butt weld or clamp style connections. Elbow connection styles come in several combinations: butt weld x butt weld, Tri-Clamp® x Tri-Clamp, and butt weld x Tri-Clamp.
For applications that require 3-A sanitary or ASME-BPE standards, CSI stocks 304 and 316L Elbows for Food, Dairy, & Beverage and BPE Elbows. We also offer Hastelloy® C-22® Elbows for more corrosion resistance.
Dimensions are consistent with industry standards.
CSI provides a comprehensive line of butt weld and Tri-Clamp components in AL-6XN® in sizes ½ – 4 inch, as well as made-to-order fittings. AL-6XN can be used interchangeably with other alloys such as 254 SMO®, 926, 904L, and duplex (2205 and 2507).
