High temperatures, low pH, and aggressive chemicals call for a material that exhibits the high corrosion resistance that traditional stainless steel alloys fail to attain. There are many alloys available to address the corrosion issues; but what makes super-austenitic stainless steel alloy AL-6XN® and nickel alloy C-22 the favorite materials for highly corrosive environments? Are the properties more attractive, or is the availability of the material in the required forms more desirable? Is one better than the other? Both AL-6XN and C-22 have a face-centered cubic lattice structure and contain...

Welding AL-6XN is a very similar process to welding other stainless steels, but there is one very important exception. This alloy requires an additional alloy to be consumed in the weld. The following video outlines these and other instructions for welding AL-6XN successfully.

Question: If I purchase AL-6XN alloy (N08367) tubing or fittings to the ASTM A270-S2 specification, will they meet the low sulfur requirements? Many end users in pharmaceutical industry require the ASTM A270-S2 (pharmaceutical quality) tubing for their application. However, sulfur requirements are commonly misunderstood, and the ASTM A270 specification covers...

When first considering your options for a new process design, one very important question to ask is: What’s the value of a skid system? There are many advantages to using a skid system, particularly for processing companies that intend to grow their business.  If the process is likely to be expanded in the future, the skid can be designed to accommodate...

A skid system is any process implement, operational device or system that can help a customer save time and money, or increase flexibility by assembling a group of modular pieces together as a single unit.  This includes: Pump carts Bio waste deactivation systems CIP systems Multi-story modular systems All of these systems fall under the broad umbrella of a...
