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 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.

*32 µ-inch Max Ra is an approximate value and is not guaranteed. Surface finish roughness shall be physically examined for “P25” using a profilometer calibrated to standards traceable to NIST. Surface finish roughness shall NOT be subject to physical examination for “P7” or “7”.

**The interior surfaces shall be mechanically polished or as drawn to a 25 Ra µ-inch (0.6 µm) maximum finish for sizes ½ – 4 inch diameter. The electropolishing process may increase the Ra values post electropolishing and have areas of preferential etching (e.g. frosting, shadowing, etc.). Final Ra values for electropolished tubing and fitting shall not be used as criteria of acceptance for this product.
