Engineers Sharpen Skills at Cargo Tank Training

Recently, two of our engineers, Will Norton and Gary Gathright, attended the NTTC Cargo Tank Test & Inspection Course, which was held in St. Louis by the National Tank Truck Carriers (NTTC). The course was designed to educate participants on the inspection and recertification of cargo tanks, especially those used for on-road transportation.

At Ledwell, we manufacture tankers under specific regulations set by the American Society of Mechanical Engineers (ASME), specifically DOT 407/412 vacuum tanks. These regulations are revised every few years, so our team must stay up-to-date. The course was a refresher for Gary, who is already a certified design engineer, and an important step for Will to become a design-certifying engineer.

The training emphasized ensuring that the designs and processes we use for our tankers meet the latest safety and legal standards. By staying current with these regulations, we ensure that the vacuum tanks we build are compliant with the law and safe for everyone on the road.

ASME Code vs Non-Code Vacuum Tanks: Understanding the Difference

ASME Code vs Non-Code Vacuum Trucks - Understanding the Difference

Vacuum tanks are pressure vessels designed to operate under negative pressure conditions. They are commonly used in various industrial applications requiring a vacuum, such as the chemical, pharmaceutical, and food processing industries.

There are two types of vacuum tanks: ASME code and non-code. Follow along to understand the difference between ASME code vs non-code vacuum tanks.

ASME Code Vacuum Tanks

The American Society of Mechanical Engineers (ASME) is a professional organization that sets standards and codes for the design, fabrication, and inspection of pressure vessels, including vacuum tanks. ASME code vacuum tanks are designed and built according to the ASME Boiler and Pressure Vessel Code (BPVC), which provides guidelines for their safe construction and operation.

ASME code vacuum tanks are subject to rigorous design, fabrication, and inspection requirements. A qualified design-certifying engineer must design these tanks. They must also be fabricated by an ASME-certified manufacturer and inspected by an ASME-approved inspector before being put into service.

Non-Code Vacuum Tanks

Non-code vacuum tanks, on the other hand, are not designed or built according to any specific code. Although their designs follow many of the same features, they do not require design and fabrication by certified manufacturers. One noticeable difference is that, unlike ASME code tanks, non-code vacuum tanks don’t have to include roll-over bars at the top.

While non-code vacuum tanks may be less expensive than ASME code tanks, they may also pose a greater risk of failure or rupture. Non-code tanks are not subject to the same rigorous inspection requirements as ASME code tanks, and they may have different levels of quality control during fabrication.

Which Vacuum Tank is Right for You?

When choosing a vacuum tank, consider your application and the level of safety and reliability required. If your application involves hazardous materials, high-pressure differentials, or critical process conditions, an ASME code vacuum tank may be the best choice. ASME code tanks offer higher safety and quality assurance and are designed to meet strict performance standards.

However, if your application is less demanding or requires a lower level of performance, a non-code vacuum tank may be a more cost-effective option. Non-code tanks are typically less expensive than ASME code tanks and may be more suitable for applications that do not require the same level of regulatory compliance.

When choosing between ASME code vs non-code vacuum tanks, consider your application and the level of performance and safety required to ensure that you select the right tank for your needs.

ASME Certification Continues

In 1916 ASME began its program for certification to companies in the pressure equipment industry. This program was developed to certify quality control systems for the design, fabrication, assembly, and inspection of boiler and pressure vessel components during construction.

Products manufactured by ASME BPVC certificate holders include a certification mark in accordance with the applicable certified section also known as a “U” stamp. A company can also be certified to make repairs or alterations to pressure vessels under the National Board of Boiler and Pressure Vessel Inspectors under an “R” stamp.

Ledwell began building pressure vessels, or in our case DOT Cargo Tanks, in the spring of 2010. This past May, we successfully completed our 5th joint review for ASME and National Board certification.

The purpose of the review is to evaluate the quality program and ensure the implementation for each product manufactured for fabrication, alterations, and repairs. Each assessment ensures the applicant’s quality program is implemented successfully and complies with requirements based on the ASME standard.

Certificates are granted after a review of the previous 36 months of work, verification of record-keeping requirements, personnel training, and required knowledge of pressure vessel design and fabrication rules.

Partnership leads to new tracked hydroexcavator

In 2019, we had the opportunity to manufacture one of our vacuum tanks combined with a crawler carrier that could change an industry.

This project was similar to others- taking an idea and turning it into reality.

To provide a solution.

In Ledwell fashion, we ran towards the opportunity.

The Opportunity

When a hydro-excavation contractor needs to perform work in hard-to-reach or environmentally sensitive areas such as swamps or marshes, it is often difficult to use large trucks.

Mats can sometimes be placed down for the trucks to drive over to protect the environment from any damage the heavy machines may cause.

Those mats are heavy, bulky, and expensive, though, and they take additional time to utilize.

The Solution

However, through a collaborative effort with Ledwell & Son, PRINOTH and Pipeline & Utility Rental Equipment (PURE), the pipeline and utility industries have a new tool to make digging easier.

The TrakVac is a compact hydro excavator built by Ledwell and mounted on a PRINOTH crawler carrier buggy. It combines the agility of a crawler carrier to access hard-to-reach areas with low-impact vacuum technology where traditional digging is more difficult, especially close to underground utilities and pipelines.

The idea was to get a more compact hydro-excavation unit into some of the harder-to-reach or environmentally sensitive areas of pipeline construction.

“The total package of hydroexcavation with the ability to ‘Go Anywhere’ (which is PRINOTH’s slogan) makes the TrakVac a true initiative and an answer to the growing demands of the pipeline industry,” says Gary Gathright, Ledwell engineer.

An industry first, the TrakVac provides a solution for unique job sites. After countless hours of engineering, manufacturing, and perfecting, we are proud to share this innovation with the world.

Dig Different’s March issue features this unique machine as a Product Spotlight. Read more about it in Dig Different’s Product Spotlight.

Robotic Welder Plays Key Role in Production

In the industrial world, a big word is efficiency – especially when it comes to manufacturing. One needs to be able to get parts, pieces, and products out fast and accurately. People are and will always be the key, but sometimes they need a little help to keep up with customer demands. That’s why Ledwell would like to introduce you to a new addition to our team – our Computer Numerical Controlled (CNC) Robotic Welder.

Our Robotic Welder is currently being used to produce over 30 types of parts – for example, our hydraulic cylinders.

We’ve decreased the time it takes to weld together a cylinder in half due to this innovation. The robot program knowledge is growing and soon will handle the output of our most highly produced parts.

This machine can move roughly three to four times faster than the average person with the accuracy and precision Ledwell requires. Where it might take a person 20 minutes to weld a single part, it would take the robot five.

The operator has two options in controlling this machine. They can either control it Offline, meaning they present a 3D model and provide commands, or they can teach the machine and guide its every movement. Either way, the Robotic Welder is non-stop.

The continuous movement is really what gives the machine an extra edge and makes it cool to watch!

Top 5 Tips on Telematics

The future is digital, and that includes how we keep track of equipment. Whether in the rental industry or construction, you want to know where your equipment is and how it’s performing. Rental Equipment Register put together a few industry experts’ tips on utilizing the most out of telematics and software.

What is telematics?

Telematics is a technology that monitors and gathers the logistics of a vehicle or an entire fleet. Telematics utilizes computer systems to collect data from various operation points, including location, driver behavior, fuel, and overall health.

Why should I consider using telematics?

There is always room for improvement, and we think these tips on telematics are just the way to help you do your job better.

1: Make the right IT investment decision:

says Loren Carlson, operations manager, Star Rentals. “Once made, it is very costly to rectify,” Carlson says. “Make sure you have a clear understanding of the pain points of the current system, or lack of system. Establish a clear understanding of what you intend to improve, and how you will measure success. The best way to do this is to solicit input from every level and area of the company.” Once completed, this serves as the basis for evaluating IT options and helps to keep the evaluation discussion focused.

2: Create an implementation roadmap:

Once the IT decision is made, invest time in configuring it before it’s rolled out, to make the user interface as intuitive as possible, says Carlson. “It may be capable of great things, but if users struggle to adapt to it, your returns will be delayed while you waste time and energy pushing users to use it. The same applies with back-end system integration. Creating an implementation Roadmap ahead of time will ensure you realize the benefits as quickly as possible.”

3: Focus on impact, not just ROI:

As you evaluate IT options, think about who and what will benefit from technology first, says Martin Roath of ZTR Control Systems. “Some benefits will be easy to quantify, while others may be more financially intangible,” Roath says. “For example, technology benefits could affect culture or customer experience in undeniable ways that are difficult to measure in dollars.”

4: Consider application flexibility:

As time passes, requirements for IT can change so be sure to look for solutions that don’t limit your future, says Roath. “As you think about your people, processes, and other business systems, be sure to consider integration capabilities that connect your business systems together,” he says.

5: Develop a training support structure:

Make the structure accessible to everyone in the company. “This can be scaled to any size business, but the key is to have expert level assistance readily available,” Carlson says.

These five tips are just the beginning. Over two dozen experienced industry professionals helped put together 50 telematics tips. We hope these help your company become more effective. Learn how even the slightest change with telematics and software can make a world of difference.

Read about all 50 tips from Rental Equipment Register.
