SSP Blog How Tube Fittings Affect Energy Consumption Posted by John Comi on Jul 24, 2014 7:30:00 AM Energy consumption is an increasingly important issue to both domestic and foreign companies. In addition to the direct energy costs, environmental regulations and the associated taxes and penalties are becoming significant issues for companies and governments seeking to have companies reduce their carbon footprints. Toward Leak-Tight Systems Tube fittings can have a significant impact on energy consumption by reducing system leaks. The logic is straight forward. Properly installed high-quality tube fittings and tubing can reduce leakage to near zero. Fewer leaks mean less fuel is consumed in production. Less fuel consumption means fewer emissions. A Cascading Affect While direct energy losses, through leaks in steam, hydraulic and pneumatic systems, are one consideration, the effects of leaks on process control and automation may have an even more significant affect on companies’ energy consumption. Instrumentation Systems In process instrumentation, leak-tight tube fitting connections are critical to achieving accurate pressure and flow measurements. Fewer leaks can also mean tighter control over process temperatures and pressures reducing the fuel consumption needed to deal with system inconsistencies. Better temperature and pressure control can also lead to higher yields. In addition, higher yields mean that less energy is expended in making products that must be discarded or remanufactured. In analytical sampling systems, leak-tight systems ensure that the required sample purity and quantity are delivered to that analyzer. Better analysis can mean more reliable system adjustments leading to better quality and lower energy costs. Automation Reducing leaks can make pneumatic and hydraulic equipment more reliable. Higher reliability can mean that automated processes can be optimized to be more efficient and the cost to run pumps and compressors can be reduced. Higher quality can also reduce maintenance costs as automated tools are operated at their designed pressures and because fewer cycles are required to meet production schedules. Using Tube Fittings to Save Energy Better efficiency is achieved in the following ways. Use tube fittings whenever possible to replace pipe fittings. Pipe fittings, especially interference-type fittings such as NPT and ISO tapered thread are more difficult to install and more susceptible to system dynamics than tube fittings. In addition, because tubing can be bent, fewer fittings are uses reducing the number of potential leak-points in the system. Ensure leak-tight tube fitting installation Leak-tight is the product of quality tube fittings , tubing selection and proper installation. via How Tube Fittings Affect Energy Consumption.
Interchanging and Intermixing Tube Fittings, Part 2 Posted by David Brown on Jul 31, 2014 7:30:00 AM inShare 0 Intermixing Tube Fittings In a previous blog, I wrote about interchanging tube fittings. In this blog, I will discuss a more controversial topic - intermixing tube fitting components. Intermixing stainless steel tube fittings means using the components (body, ferrules or nuts) from one manufacturer with the components from another manufacturing. Some Issues Most manufacturers discourage this practice. Their logic is easy to understand. While most tube fittings seal using the same basic principles, each tube fitting design is unique and each tube fitting components is specifically designed to work with the other components to achieve a seal can increase dramatically. The more dissimilar the design; the more likely it is that they tube fitting will leak or fail. In order to work as designed, the components from one manufacture would have to be identical in geometry and function as the intermixing brand. Even then, it would be advisable to conduct testing to ensure that the tube fitting combinations sealed properly. So why do companies intermix tube fittings. The basic reasons are: Many different tube fittings are available at their facilities. OEM equipment, site built systems, contractor supplies and other sources might increase the number of tube fitting designs in a plant. Installers and maintenance people are not able to tell the difference between tube fittings tube fitting designs. Purchasing may change suppliers and, by extension, change their tube fitting supplier. When maintence orders new fittings to repair a system, they order the current tube fitting carried by their supplier. The current tube fitting vendors carry only one tube fitting design and that design is not compatible original fitting. Done incorrectly, intermixing can lead to leaks, productivity and quality problems. At worst, it can lead to safety and environmental problems. Possible Solutions It seems that the solutions might be straight forward. Maintenance and Purchasing Departments must recognize that they have a variety of tube fitting designs in their facilities and that it is nearly impossible to change this. Purchasing should establish channels to obtain replacement components for each brand. Establishing a mulit-line source for most or all of your tube fitting replacements will reduce handling and inventory costs and stocking issues. Train maintenance and installers on the proper identification and replacement of tube fitting components. Check to see the tube fitting components have been tested to intermix with the current component. Conclusions Intermixing tube fitting presents problems for maintenance and production. The best course of action is to address these situations inadvance by recognizing tube fittng brands and having a source that can supply components that are completely intermixable with the original brand. via Interchanging and Intermixing Tube Fittings, Part 2.
Intermixing Tube Fittings This is the first of a two articles focused on interchanging tube fittings and intermixing tube fitting components. Part one deals with interchanging tube fittings. Part two will take up the issues in intermixing tube fitting components. The Problem Creating leak-tight systems is important to most manufacturing process. The integrity of instrumentation and control systems have significant impact on: Safety and the environment Product quality Productivity and costs When tube fittings leak, it is usually due to improper installation, tubing quality, or product selection. Other times leaks are caused when the components of tube fittings are mixed when making up a fitting. This is called intermixing tube fittings. We will talk about this in my next blog. Interchanging tube fittings is when one tube fitting brand is substituted for another. While this usually happens during maintenance, especially when OEM equipment or original system installation need updates or replacement. It can also occur when an individual maintenance worker or contractor substitutes the brand specified by the system designer with another brand. This usually happens because: The current or specified brand is not available at the time of installation The installer or owner company prefers a different tube fitting brand based on cost and/or experience with the brands. Some Considerations Installers and desigers can be confident when interchanging tube fittings if: They know the replacement brand is a “drop-in” replacement in terms of both size and performance for the current component. Installers are familiar with assembly and installation practices. The fittings have the necessary approvals and meet the performance standards for the application and for material traceability. And Some Guidelines Therefore, when choosing a substitute tube fitting brand, installers and purchasing agents should choose brands that: Are drop-in substitutes for the current brand in terms of size and installation practices. This means that the distance between the points where tubing seats into the tube fitting are identical. Have documented performance demonstrating that the tubei fittings meets or exceed the performance of the current tube fitting brand. Offer documentation and certification that meet material and traceability requirements for the industry and application. Conclusion Designers, installers and OEMs having service issues or are who simply looking for a replacement or backup for their current tube fitting brand can save a lot of engineering and maintenance time, installation problems, and dead inventory by following a few simple guidelines. via Interchanging and Intermixing Tube Fittings.
