If not finished correctly, stainless steel will sometimes develop specks of rust. That’s unsightly and can lead to customer complaints. Corrosion-resistant material isn’t supposed to suffer that problem, and it won’t if the right finishing techniques are used. Plating, electro-polishing and even grinding are some of the ways we prepare perforated tubes for service. Here’s a review of the options. Fitness for Purpose Perforated tubes are used primarily for filtration. As such, hole size, shape and “open area,” (the ratio…

There are few applications where perforated tubes can function as needed without some kind of cap or fitting at one or both ends. Fittings provide mounting and connection options while end caps ensure fluid passes through the perforations rather than out the end of the tube. Here’s an explanation of your options for perforated tube end caps and fittings. Making Connections There are two ways of joining one perforated tube to another tube or mounting point: the joint is either…

Imagine a filtration system that blocks or catches small stuff while allowing large objects through. If you think about how a filter works it seems impossible. Filters use a mesh or screen to trap everything too large to pass through the holes. How can a filter do the reverse and trap small particles while passing those that are larger? The answer lies in a clever application of perforated tubes. Read on for details.   Water Filtration In most US cities…

Fuel contamination in a car or truck is seldom fatal. In an aircraft it’s a different matter. Water can freeze and block fuel delivery lines, which will stop the engine or engines. Other types of contamination can be just as problematic. When particulates block fuel system components pilots lose control over the engines and an emergency landing is usually required. Two-stage coalescer-separators are designed to prevent this problem. These rely on cartridge-style filters made from perforated tubes. Here’s more detail…

A failed filter will wreak havoc in a hydraulic system. Particles that aren’t trapped in the filter media will cause wear, damage seals and block small orifices like those in servo valves. Without effective filters hydraulic equipment will fail prematurely, needing expensive repairs and causing costly downtime. That’s why every hydraulic pressure system is designed with filters. Two essential but often overlooked aspects of a hydraulic system filter are the inner support tube and the outer protective cage. These provide…

We’re not the only company who has their ISO 9001 certification. Where we think we differ is how we view it. Some companies see certification as a mark of achievement, and it is, but we view it more as a tool that helps us meet the expectations of our customers. Here’s a deeper dive into the topic to explain this attitude.   An Overview of ISO 9001   ISO is the International Standards Organization. It’s through their work, and that…

Given that there are at least three ways to make a metal tube, it’s reasonable to ask which is best. Each manufacturing method has advantages and disadvantages but which matter most depends on the end application. Here we’ll review the process used for making spiral welded tubes and identify the benefits that result.   Tube Manufacturing Methods   Rube Goldberg could probably come up with a dozen different ways to produce tubing, but there are only three that you’re likely…

    Our products might not be as diversified as it’s uses but we understand how crucial it is to have parts you can rely on to get the job done.  Our Process Mastery   We’d venture to say that perforated tubes are unlike any other fabricated product. When we started out we had to develop the production technology that makes them possible. As a result, we’d argue that today our expertise in every aspect of their manufacture is deeper…

Product differentiation is essential for business success. It protects against price competition and helps increase margins. For businesses that make a physical product, custom components are an effective way of achieving differentiation. Competitors all have access to the same parts catalogs but working with a custom manufacturer lets a business offer unique features and capabilities.   “Custom” Perforated Tubes The design requirements for any perforated tube product are usually quite complex. At the same time though, they usually come down…

According to the National Safety Council (NSC) flying commercial is just about the safest way to travel. Even so, many passengers have a fear of flying and for one rather obvious reason. Unlike in a car or on a train or boat, if a problem should occur you can’t just coast to a halt. This is why quality standards for aerospace components are so demanding: every component has to perform as expected and there’s no margin for error. Perforated tubes…
