Testing for Leaks in Pressure Vessels

If you need to contain gases or liquids at a pressure level higher than the ambient one, you need a high pressure vessel. These vessels are used in various industries, including petroleum refining, chemical processing, and boiler and storage tank manufacturing. 

One of the challenges encountered by facilities that use these vessels is material leakage. If there’s leakage, the pressure will decay, the gases will get contaminated, and the whole vessel will be at risk of becoming damaged. Leakes can also cause increased operational costs, decreased system efficiency, and heightened toxic emissions. 

To counter this issue, leak testing is done. And there are various ways in which a pressure vessel manufacturer can perform leak testing and ensure that their products are fit for service. Here are the seven most commonly used methods: 

Helium Leak Testing. In helium leak testing, this inert gas is used to pressurize the vessel. Then, a special device will be placed inside the vessel to trace and measure the size of leakage. Because this testing is more sensitive than most other methods, it can detect even if the size of the leakage is small. Only qualified helium leak testing services should be considered for this task.

Pressure Decay Testing. One of the most used leak tests, this method is done by using a pressure decay tester to pressurize the vessel with a non toxic gas (typically air). The gas inside the vessel is then tracked to check the amount of decay or pressure loss. From the elapsed time and the amount of decay, the leak rate can be calculated. 

Vacuum Decay Testing. In this test, a certain level of vacuum is achieved by removing all media within the vessel. Once the desired vacuum degree is attained, any increase in pressure will be monitored and recorded. Again, the amount of pressure increase, and the elapsed time will be used to determine the leak rate. 

Hydrostatic Testing. Like pressure decay testing, this technique subjects a high-pressure vessel into pressurization. However, instead of air, incompressible water will be used to pressurize the unit and subsequently determine the leak location and flow rate. Water is commonly used because it won’t impact the future functionality of the vessel. Companies that specialize in pressure vessel fabrication would most likely conduct hydrostatic testing on vessels they make for clients

Ultrasonic Testing. When there’s a pressure leak, the sound waves within the vessel are affected. Using this principle, this test involves sending ultrasound waves to the vessel. If these introduced waves are disrupted, it means that there’s a leak in the vessel. Professional personnel will estimate the leak’s location and its size. 

Radioisotope Testing. The media inside the vessel is combined with a radioisotope (e.g. Sodium-24, krypton-85). A special device is used to check if any of the radioisotope escapes the vessel. If any of the radioisotope being used has seeped out, it means that there’s a leak in the vessel. Though pricier than other tests, this type of test yields more accurate results. 

Dye Penetrant Testing. This test involves applying a white substance called a developer on one side of the vessel. A fluorescent dye is also applied on the opposite side. A vessel with a leak will enable the dye to penetrate and the wall, appearing on the side where a developer was applied.

Kitchen Islands That Please the Eye and The Chef

Installing kitchen islands is a popular way of making kitchens more functional. These islands add more storage areas and counter spaces to prepare, cook, and even eat meals. Not only that, but they also boost the aesthetic value of this part of your home. However, not all kitchen peninsula ideas can be successfully turned into reality. 

Because kitchen islands are typically the focal point of kitchens, they should be well-designed and optimally incorporated into your layout. Various factors also affect their size and shape — from how busy and spacious your kitchen is to how many you are in the household. 

Materials, island height, and other features are also key considerations. But to help you out, we’re listing a few of the top kitchen island features that you should consider. When executed right, all of these features can please the ordinary eye and even the chef in your home. 

Base cabinet. This is one of the most basic elements of your kitchen island design. The anatomy of a base cabinet is comprised of the framework, any electrical or plumbing components, the actual cabinetry and countertop material. To this base cabinet structure, you can design in a seating area, a handwashing station, some small appliance storage and even a wine chiller.

If you’re looking for kitchen island designs with seating and you have a huge amount of available space, in-kitchen dining can be ideal for you. It’s a built-in island that can host 2-4 stools for countertop dining. Depending on how spacious your kitchen is, you can add a couple more seats so you can do away with a separate table for your dining pleasure. 

U-shaped island. A busy kitchen requires ample preparation space. This kitchen island type provides you with just that. Because of the extra counter space it offers, you can also add some countertop appliances to make it more functional. It also provides more storage space. However, because it takes up space, this island is generally recommended for a kitchen that is already large and airy in the first place. A smaller kitchen can be designed in a U shape but probably not include an island. Perhaps some kitchen peninsula ideas would work in your smaller kitchen,

L-shaped island. If you want to have a unique island while addressing limited kitchen space, one of your options is going for an L-shaped one kitchen island with stools. Though it’s less bulky than U-shaped islands, it can still provide ample counter and storage space. 

Looking for a unique kitchen island design? Perhaps a crescent shaped kitchen island is right up your alley. A departure from the common shape of an island, this is ideal if you wish to have bar-style seating in your kitchen. Compared with the two previously mentioned island shapes, this provides more room to maneuver and go around your kitchen. 

Double-tiered island. How about a double island kitchen layout? This type of island is recommended for home cooks who want to have separate counter space for cooking and preparing, and another one for dining. If you’re fond of hosting parties and welcoming guests into your home, this is the most suitable layout for you.

Alignment Technology for Structural Engineers and The Military

For a structure or a whole system to function as its designers and engineers envisioned it, alignment is critical. Alignment refers to components’ geometric orientation. Devices such as theodolites assist in ensuring that each component is placed in its proper position. 

Optical alignment tools have several applications. They can be used to monitor bulges and distortions in dams or bridges. They can also be used to measure a building’s sway in the wind or during an earthquake. They also play a vital role in aligning surfaces and radars on ships and aircraft. 

Two of the most popular applications of alignment technology are in structural engineering and the military. 

Alignment in Structural Engineering

In the world of engineering, even a seemingly small error can lead to huge and costly consequences. Structural engineers, in particular, are concerned with proper alignment as it can affect the structural soundness of buildings, bridges and roadways. 

They rely on a number of tools to check if a component has accurate orientation and position. These include precision optical instruments, which provide better accuracy when examining the alignment of an object. For instance, theodolites can be used to measure the vertical and horizontal angles of a particular subject. 

These devices aren’t just helpful in the construction phase of a certain structure. Engineers also use them when monitoring and detecting alignment shifts. For instance, if a truck crosses a bridge, they use alignment tools to check how it impacted the alignment of the components of the said bridge. 

If a dam has become susceptible to base erosion, engineers can also use these instruments to inspect the structure for any distortion. If an earthquake hits a certain area, these tools are helpful in assessing the impact of the sway of a building on its structural integrity. 

Alignment in The Military

Optical alignment tools also have various military applications.

One is surveying and navigation. The telescopic alidade is an optical device that is typically mounted on navy ships to see objects in the distance. Even back in the late 19th century, the earliest iteration of this tool has been helpful in mapping the topographical features of certain areas. 

There are also optical tools designed to make sure that radar system components are manufactured and installed accurately. These rather sensitive components are critical parts that enable radars to accurately determine the range, angle, as well as velocity of approaching or surrounding objects. 

In assembling different structures in a military vehicle, these devices provide that much-needed aid in guaranteeing that various components fit the required position and angle specifications of the design. Military personnel also use these instruments to determine the alignment of a specific structure in relation to the rest of the ship of aircraft. 

There are also optical systems that are used to calibrate rocket artillery and other firearms mounted on military fighting vehicles. Military boresights help check the accuracy of these large guns found on military vehicles. 

But whether it’s for military or structural engineering, the importance of these instruments remains the same: They ensure precise alignment, which can maximize the functionality and lifespan of a structure. Calibration and instrument repair services like Warren Knight can help keep your equipment in tip top shape.

Key Elements of Dispatching Software

In a fast-moving society, having a reliable radio dispatch system is essential for organizations with delivery operations. From food and beverage businesses to e-commerce ventures and other logistics providers, many rely on radio dispatch or a PTT over IP system to deploy their drivers cost-effectively and promptly to the field. 

A dispatching software is designed to help with driver routing and vehicle tracking. It’s helpful not only in making operations more efficient but also in enhancing the overall customer experience. This article discusses the key elements of dispatching software. 

Tailored dispatching

Most organizations that perform dispatching have unique needs. These depend on several things, including the current size of their fleet and roster of drivers, dispatch locations, and other delivery requirements. 

With a digital dispatch system, dispatching decisions can be customized depending on your current considerations. It also allows for both automated and manual dispatch options, so you can intervene manually whenever needed. For instance, there’s a customer with a unique query that must be addressed immediately. 

Automated scheduling

Automation is an often heard word when it comes to optimizing various business operations. Automation technology is also beneficial for appointment scheduling. If this aspect is digitized, you can easily track vehicle progress and send timing updates to customers that may have requested SMS updates.

For instance, if your customer selected a 24-hour delivery option, you’ll automatically know that a specific product has to be delivered in one day to that customer. Instead of dealing with customer calls and manually keying in data to a database, an automated scheduling feature can help you significantly save time and effort. 

Optimized route selection

Groups that use a radio dispatch system and software also benefit from the element of optimized routing. This tool allows you to determine the most efficient route for your fleet, taking into account various factors such as distance, current traffic conditions and time needed to complete various delivery phases. 

Together with route optimization, this software also has a smart batching element that collates orders that fall in the same delivery windows. This will make your dispatching more streamlined and cost-effective. 

Easy tracking across the delivery process

From the time an order is taken out of inventory to the point that it gets fulfilled, your drivers could face several (unexpected) barriers. Dispatch software can help facilitate easier tracking across the various points in your delivery flow.

You can also use this tool to alert or notify your customers (e.g., the exact location of your driver, estimated time of arrival, unavoidable cause of delay, and what you are doing to cope with it). This helps improve their overall experience of doing business with you. 

Reliable communications

If you have a digital dispatch system, it’s imperative to have a strong communications system as well. Today, push to talk (PTT) over Internet Protocol (IP) is being used by many clients because of its accessibility, interoperability with cellular systems, and scalability. With a simple press of a button, one of your staff can directly communicate with another person. 

Every device with access to your PTT software will be able to talk through it. In addition, its reliability is highly commendable because PTT software has a short latency time (down to 100 ms if you have a 4G network). Meaning, you can easily reach out to a person out in the field and relay any information, critical or not.
