Road Tubing

Posted on June 14, 2022June 24, 2022 by Caserta Marketing Team

If you drive regularly, chances are you’ve seen some of those small black tubes that often sit across a given roadway, whether on a construction site or in another area. Many of us have a similar question here: What exactly are those tubes, and what do they do?

At Thomas A Caserta, Inc., we’re your one-stop shop when it comes to numerous rubber products, including rubber tubing and cord. What exactly is that road tubing you’ll see, and what are some of its primary purposes? Here are several themes to consider.

What Road Tubing Is

First and foremost, what are we even talking about? Technically, the industry term for these small tubes found on the road that can be driven over is “pneumatic road tubes.”

Essentially, these tubes serve as sensors on the road. They send small bursts of air pressure along the tubing whenever a vehicle passes over them, which is then received and analyzed by a computer. This data can then be used to help determine traffic flow patterns, average speeds, and more.

This type of road tubing has become increasingly popular in recent years as a relatively low-cost way to collect data on traffic patterns. It will often be found in construction zones, as a way to help officials determine if the work being done is having an impact on traffic patterns (and, if so, what that impact is).

Primary Road Tubing Purposes

Here’s a rundown of the most common ways these road tubing products are used:

Traffic patterns: As we just touched on, one of the primary uses of road tubing is to help officials determine traffic patterns. This data can be used to make decisions on everything from traffic light timing to construction schedules.
Speeding: Road tubing can also be used to help enforce speed limits. Data collected by the tubes can be used to pinpoint areas where speeding is a problem, which can then be targeted by law enforcement.
Traffic counts: Road tubing can also be used to simply count the number of vehicles that pass over a given stretch of road. This data can be useful for planning purposes (for example, if a city is considering adding a new traffic light or stop sign).
Vehicle types or class: If two or more tubes are set up in close proximity to one another, they can be used for even more advanced data collection, such as determining the types or classes of vehicles that are using a given road. This data can be used for everything from marketing research to traffic planning.

As you can see, there are a variety of ways road tubing products can be used. If you’re in need of high-quality rubber tubing or cord, look no further than our team at Thomas A Caserta, Inc. Contact us today for more information on these or related materials!

Benefits of Working with an American Manufacturer

Posted on March 28, 2022March 28, 2022 by Caserta Marketing Team

American manufacturing has a long, proud history. In recent years, more companies are coming to understand the benefits of working with an American manufacturer, and they’ve turned away from offshore operations to take advantage of domestic high-quality products. By purchasing American-made and manufactured parts like rubber washers, gaskets, silicone tubing, and more, you reduce your shipping costs, speed up turnaround times, receive better quality, and support local communities all at the same time.

These are a few of the many benefits of doing business with an American manufacturer.

Quicker Turnaround Times

Offshore products must travel farther distances to reach their destination, lengthening lead times to months. Overseas shipments are also subject to global supply chain issues and other unexpected delays. When you order parts from an American manufacturer, your products don’t have to travel as far, taking only days or weeks to arrive. This is crucial in the modern e-commerce market, where consumers increasingly expect online orders to arrive quickly.

Higher Quality Products

Natural rubber manufacturers based in the United States are subject to American laws and manufacturing regulations. This includes higher safety standards for workers and environmental regulations to help companies reduce their carbon footprint. Furthermore, domestic manufacturing allows companies to oversee production directly and ensure stringent quality control measures. To achieve these high standards of excellence, U.S. manufacturers invest in high-quality equipment and extensive training for their employees.

Reduced Delivery Cost

Because your products don’t have to travel as far, the cost of delivery is much lower. Unlike overseas shipping, domestic shipping offers more options, so you can shop around to secure the lowest delivery cost while avoiding the customs fees and international taxes associated with purchasing from an offshore manufacturer. With no language barrier or cultural differences to navigate, you also reduce the risk of miscommunication and shipping or production errors.

More American Jobs

The ripple effect of buying American-made products is profound. You would be supporting the companies that provide jobs for people in this country. Local manufacturers often source materials locally as well, which creates a strong network of businesses that support American workers and their families across industries. As these communities develop more spending power, they also buy from other local businesses, supporting job creation in retail, transportation, distribution, technology, and more. As a result, American manufacturing stimulates local and national economic growth.

U.S. Manufacturers Pay U.S. Taxes

Offshore manufacturers often avoid paying certain U.S. taxes, which was part of the appeal of offshoring operations. But with overseas shipping costs skyrocketing, this is becoming less of a draw for manufacturers. Reshoring production is proving more fruitful, since paying U.S. taxes serves their community and country in a variety of ways, including improved infrastructure, education, and social programs.

Consumers Trust the “Made in U.S.A.” Stamp

U.S. consumers tend to trust products that are made in their home country, and a “Made in U.S.A.” stamp can be the selling point that encourages them to choose that product over another. The popular perception that American-made products are of a higher quality than foreign-made goods is accurate. As Americans become more aware of the social and environmental impact of their choices, they increasingly prefer to buy products from companies that prioritize safety and respect for their workers, reduce their carbon footprint, and give back to local communities.

Key Design Considerations for Gaskets

The installation of the wrong gasket can result in leaks, damage, and other issues in a fluid system. It can also cause the premature wear and failure of the gasket, which translates to frequent investment in gasket repair and replacement operations. With these consequences in mind, it is important to use the right gasket for the given application. Below we outline some of the factors to consider when designing a gasket to ensure it functions as intended.

Construction Material

The construction material chosen largely determines how the gasket will perform. As such, it is essential to consider what qualities are expected of the finished gasket and what materials fit these requirements. When vetting potential material options, some of the properties to keep in mind include:

Density: the material’s mass per volume (lbs./ft.³)
Hardness: the material’s ability to resist plastic deformation resulting from indentation, penetration, and other mechanical forces
Elasticity: the material’s ability to return to its shape and size after experiencing deformative forces

These properties are critical to the sealing performance of the gasket. However, the levels required depend on the system in which the gasket will be installed. For example, sponge rubber (both open-cell and closed-cell) generally exhibits lower density and better elasticity than solid rubber, which makes it suitable for some—but not all—applications. It may be helpful to acquire samples of materials to determine which one best fits a given system.

Some of the most common materials used in the manufacture of gaskets are:

Silicone: Silicone is a highly versatile and resilient material that is available in solid, foam, and sponge variations. It does not react with or deteriorate when exposed to many chemical substances. It is often used for gaskets due to its ability to form a tight seal, remain flexible in high or low temperatures, and resist water, shrinking, and UV and ozone damage.
Neoprene: Neoprene is a synthetic rubber compound that exhibits good durability, resisting damage and degradation stemming from exposure to UV radiation, ozone, chemical and corrosive compounds, and oils and other petroleum-based products. It also remains flexible in temperatures as high as 120° C and as low as -40° C.
Nitrile: Nitrile is a synthetic rubber that finds use in a wide range of applications. However, it is particularly suitable for environments exposed to grease, oil, and water.

The design of a gasket depends on the system in which it will be installed. Tailoring the gasket to fit snugly between the mated components is essential; otherwise, it will not function as intended. The design elements to consider include:

Shape: the geometric form of the gasket (from the face)
Cross-section: the geometric form of the gasket (from the profile)
Thickness: the distance between the gasket’s faces

Application Environment

The operating and environmental conditions to which the gasket will be subjected affect what construction materials and gasket designs are appropriate. When determining the above two factors, it is critical to keep in mind the following:

What temperature ranges are expected?
What operating pressures ranges are expected?
What chemicals will the gasket be exposed to during operations and maintenance services?

The above list of questions is not all-inclusive. There are many other operating and environmental factors that can affect a gasket’s performance. Partnering with an experienced and knowledgeable gasket supplier can help determine which gasket materials and designs are suitable for a particular application.
