Mobile Cleanrooms vs. Modular Cleanrooms

July 1, 2021

Both manufacturers and researchers can find themselves in need of a temporary cleanroom for operations. The reasons can vary as much as the product or research involved, whether it’s to support a new clinical study, as an intermediate solution during planned cleanroom maintenance or as an interim stand-in while a new cleanroom is being constructed….

Comparing 2B Surface Finish With and Without Electropolishing

June 30, 2021

As we’ve written many times before in this blog, stainless steel is far more than just “corrosion resistant metal.” While it is true that its material strength and resistance to corrosion have made it versatile and the material of choice for many applications, it is also because it can be adapted to fit specific conditions….

Myth – Rouge is a Protective Layer

June 15, 2021

A recurring myth in some industries is that “rouge is a protective layer” that enhances, rather than degrades, stainless steel’s durability. This mistaken belief is primarily based on certain types of rouge being considered “stable” and remaining affixed to the surface – being perceived as acting similar to a coat of paint. “Stable” rouge is…

Visual Examinations for Corrosion and Damage

April 26, 2021

A key action that is taken to prevent corrosion or damage in stainless steel systems is also the most basic – a physical, visual examination. Depending on the component, its location as well as Current Good Manufacturing Practices (cGMP) regulations, the examination can be done with unaided  eyes and a light source, or it can…

How to Choose the Right Passivation Service Provider

February 18, 2021

It is a common misperception that stainless steel is corrosion-proof. The reality is that stainless steel is highly corrosion-resistant. This means that its passive layer – the surface of the stainless steel which protects the rest of the metal – must be regularly maintained and strengthened to ensure many years of reliable service. While we…

Benefits of On-Site Electropolishing

February 4, 2021

There will come a time when even the best maintained system will require work to ensure that its inner surfaces are properly smooth. This can be unplanned, such as due to pitting caused by chlorides attacking the surface of the stainless steel, or an agitator failing and scratching the sidewall. Or planned outages can take…

The Importance of Passivated Stainless Steel for Biopharmaceutical Applications

January 8, 2021

Contamination is the bane of almost any manufacturing process, but when the product being made is pharmaceuticals, even a small amount of contamination can have disastrous results. Because of its high resistance to corrosion, austenitic stainless steels such as 304L and 316L are frequently the go-to materials for construction of tanks, supply lines and other…
