pressure gauge | Pressure Instruments | Oil & Gas | sour gas

This article is based on a white paper written by John Carissimi and Jeremy Payne in 2015 and rewritten on May 6, 2024. Sour gas and crude oil operations involve harsh conditions with a high risk of corrosion. Metals and alloys used in environments with hydrogen sulfide (H2S) are especially prone to corrosion and stress cracking, which can lead to material failure and dangerous fluid leaks in your system. To enhance safety and prevent equipment failures, the National Association of Corrosion Engineers (NACE) established control standards for any instrumentation used in these types of applications. As the Product Marketing Leader for process gauges at Ashcroft, a global leader in pressure and temperature instrumentation, I have spent the past 15 years answering questions and guiding customers on the importance of ensuring compatibility between your instruments and process media. In this article, you will get an overview of the NACE standards that specifically address corrosion that can occur with exposure to sour gas or sour crude. You will also learn what to look for when selecting pressure and temperature instruments for your sour gas and crude applications. When you are done reading, you will be able to access additional resources to help make informed decisions about selecting instrumentation for corrosive operations.

measurement instrument accessories | manifold valves

This article was originally published on January 10, 2022, and was updated on March 13, 2024. If you work in the oil and gas or chemical industry, or even in a power plant, you know that a manifold valve blocks the flow of fluid in your system so the process media will be isolated from pressure instrumentation. You also know that a block-and-bleed manifold blocks the upstream process media from the instrumentation while allowing the bleeding off (venting) of the remaining fluid from the system on the downstream side of the manifold. But when you need to know which manifold valve is the right one for your specific process, that's where we can help. Ashcroft is a leading authority in pressure instruments and the accessories that help them operate at peak performance. As the senior product manager for this segment of our line, I have had the opportunity to train many customers and distributors on this very subject. Read this article to learn the various manifold valves, how they are different and the mounting options you can choose from. When you are done, you will also find additional resources that may be of interest to you.

pressure gauge | Pressure Instruments

This article was originally published on June 9, 2021, and was updated on March 4, 2024. Pressure gauges play a critical role in your process applications. They accurately and reliably measure and monitor pressure to determine if process systems are working effectively and efficiently, or if you need to make system alterations or adjustments. This helps ensure the safety of your personnel, the efficiency of your processes and the quality of your products. But what happens when your pressure gauges stop working? Your entire operation is at risk. That's why periodic instrument audits are good practice. Ashcroft has been conducting comprehensive instrument audits for 10 years. As the product lead for process gauges, I see the results of these audits and can tell you why instruments fail in the first place. The good news is that most of these “instrument killers” we've identified can be prevented if you know the warning signs. In this article, you will learn the primary indicators that tell you your pressure gauge may be failing and the 6 most common pressure gauge problems and solutions that we found in our instrument audits. When you are done reading, you will know what to look for and be prepared to address any of these issues ahead of time. Armed with this information, you will be able to keep your processes running safely, smoothly and effectively.

pressure gauge | absolute pressure | vacuum pressure

This article was originally published on December 13, 2021, and was updated on February 4, 2024. Different industrial applications require different types of gauges to measure pressure at various points of the process. Mechanical pressure gauges, for example, can be used to measure absolute pressure, vacuum pressure and compound pressure. If you’re not selecting the appropriate kind of pressure to be measured, your gauge may not provide you with the required “readable” pressure scale. Ashcroft has been manufacturing pressure and temperature instrumentation since 1852 and as the senior product manager for process gauges, I have been fielding questions on the subject for the past 15 years. In this article, I will take you through the various types of pressure and review the different gauges and transducers available to meet your specific pressure needs.

Pressure Instruments | cryogenics

Liquefied gases, such as nitrogen, oxygen and helium, are used in many cryogenic applications. To measure pressure in these situations, your pressure instruments must be able to stand up to very low temperatures. So, how can you effectively measure process pressure when your pressure gauge is not rated for such a low cryogenic temperature? In this article, I will discuss cryogenic applications, and the different mounting options and accessories available that can help protect your pressure instruments from the effects of very low temperatures.

Product Selection | pressure gauge | overpressure

If your application can experience overpressure, your pressure gauge needs to withstand those negative effects. Pressure line spikes and “water hammer” may introduce pressure beyond the operating range of the instrument and cause damage. How can you protect your pressure gauge from the impacts of overpressure? This article will discuss some of the options available for overpressure protection to keep your application running, even in harsh environments.
