Exotic Alloy Tubing & Fittings
Due to the demanding and complex nature of many of today’s sanitary processes, additional corrosion resistance is needed beyond the capabilities of conventional alloys. In order to solve this problem, Pureserve Systems is able to provide customers with AL-6XN and Hastelloy C-22 tubing and fittings.  Pureserve Systems supplies a complete line of sanitary tubing and fittings in AL-6XN alloy for the processing industries. AL-6XN alloy provides superior corrosion resistance where traditional 316L stainless steel components are inadequate. AL-6XN alloy is a super-austenitic metal designed to resist crevice corrosion, pitting, chloride-induced corrosion, and stress corrosion cracking. It can also withstand alkaline and salt solutions, protecting against metallic contamination of product and preventing rapid degradation of the fluid transfer system. Originally developed for seawater applications, AL-6XN is used successfully in food, pharmaceutical, and biopharmaceutical processes. The "superalloy" resists the attack of corrosive food and beverage products such as: sports drinks, ketchup, soy and barbecue sauce, and salsa. It is also beneficial in fine chemical, cosmetic and pharmaceutical (cosmeceutical), brewery, desalination, semi-conductor, aerospace, biopharm, pulp and paper, and gas handling applications.  Pureserve Systems offers customers polished-surface Hastelloy C-22 tubing with corrosion resistance superior to 304 and 316 stainless steels or AL-6XN alloy. Sanitary, polished tubing is manufactured in common industry dimensions from 0.5" through 1" O.D. Mill finish tubing is also available in 1.5" and 2" diameters. Tube fittings are available in the same sizes as the sanitary tubing, 0.5" through 2" ODs. Most fittings are offered in the standard BPE dimensions. Heavy wall tank ferrules are also available in larger sizes, since they weld directly to tank shells and heads and do not require tubing as a component. Most Hastelloy C-22 fittings are available in butt-weld form, Tri-Clamp, and I-Line. Custom fittings are available upon request. The standard finish on AL-6XN and C-22 fittings is 32 microinch RA ID and OD. Mechanical abrasive or electropolish finishes are also available with a 25RA max ID finish. Unpolished fittings may be available upon request. |
