How to Keep Contaminants Out During Pressure Calibration
Sand, dirt, natural gas liquids (NGLs), water and other liquids can be a serious problem when calibrating pressure instruments on oil or natural gas pipelines. When liquid is mixed in with gas it can contaminate pressure instrumentation and introduce measurement errors. This is particularly a problem when measuring low pressures or differential pressures as any liquid can increase measurement uncertainty. To help reduce measurement uncertainty and to prevent solids and liquids from contaminating your pressure instruments Ralston Instruments has introduced two helpful products.
Taking Better Gas Samples From Low Pressure Gas Wells
Taking gas samples from low producing wells or low flow pipelines is a challenge. Ralston Instruments has created a solution to this problem.
Regulating Compressed Gas Just Got A Lot Easier
Our new Pressure Regulation Kits come with everything you need right out of the box to connect to a compressed gas cylinder, control gas pressure quickly and precisely and connect your hose quickly to the device being calibrated.
Ralston Instruments Awarded ISO 9001:2008 Certification
As a result of several years of effort Ralston Instruments has been awarded ISO 9001:2008 certification. This certification is one of the most widely recognized international quality system standards. This has several real benefits to our customers.
Adapting a Pressure Calibrator from Medium Pressure Connections to Quick-test and Quick-test XT just got easier
Do you have pressure calibrators, hand pumps or comparators with Medium Pressure fittings but cannot find the right adapter for your application? Do you connect to Medium Pressure fittings in the field or in the lab? Do you have trouble getting the correct Medium Pressure adapter due to limited pressure range, expense or lack of selection? If the answer is yes to any of these questions then we have the solution for you.
Ralston Male NPT Quick-test Fittings make periodic calibration of pressure instruments as easy as can be
Do you need to periodically calibrate pressure instruments in the field in harsh environments? Do you have to check pressures of systems that are under pressure? Do you need the reliability of a dual pressure seal system?
Calibrate Multiple Pressure Instruments At Once
Do you need to switch between different sizes or types of process connections when calibrating pressure instruments? Do you need to calibrate large quantities of pressure devices in an environmental chamber?
Calibrating DP Pressure Transmitters Just Got A Lot Easier
Get in and out quickly with a DP Transmitter Adapters. Ralston DP Transmitter Adapters make calibrating pressure transducers a snap.
Ralston Block and Bleed Valves Make Your Gas Last Longer
Ralston Block and Bleed Valves make pressure calibration even easier. Save compressed gas and make calibrations go more quickly with the Ralston Block and Bleed Valve.
More Testing. Less Taping
Female NPT Quick-connect adapters convert any NPT connection to Quick-test. Quickly switch between many devices under test without using a wrench or thread tape.
How Ralston Quick-test Adapters Save Time
Make a high pressure connection to Swagelok, Parker, SSP or other tube fittings without a nut and ferrules or a wrench.
The Higher the Pressure the Tighter the Seal
Watch the video of how our NPT Male Quick-connect Adapter makes a bubble tight seal on any female NPT port without thread tape or a wrench.
How to keep contaminants out of your gas pressure calibration system
In many gas pipelines, chemical plants and refineries there are contaminants in the process line. These contaminants can pose a threat to the pressure calibration system regardless of whether they are corrosive gases, natural gas liquids or water. By working proactively to keep contaminants out of your pressure calibrator you can extend the life of your equipment and reduce your maintenance costs. But what is the best way to do this?
Why We Calibrate Pressure and Temperature Transmitters
Like all markets, the oil and gas industry has buyers and sellers. Buyers want to make sure they are getting what they pay for and sellers want to ensure they are getting paid for what they are providing. But how does each party know exactly what is changing hands when the commodity is something that is difficult to isolate and measure --like a gas? How can each party feel good about the transaction if they can't see or weigh the goods that are being sold?
Ralston Instruments releases a new Gas Sampling Pump
The new SP0V Gas Sampling Pump can pull natural gas from low producing wells and boost it up to a pressure that can be used in a sample cylinder easily and quickly.
Ralston Instruments Releases New Connect Catalog
Ralston Instruments has released a new, updated Connect Catalog which is greatly expanded. It also has interesting application notes, illustrations and reference information on how to select the best Quick-test hose or adapter for the job.
Ralston Instruments Achieves CE Certification for Nitropak and Exceeds Standards by 60%
Ralston Instruments has passed the rigorous testing scheme for CE certification in the European market.
Ralston Instruments Introduces New Quick-test Hose Configurator
The new Ralston Instruments Quick-test Hose Configurator allows you to customize the exact hose you need for a very specific job. When our standard hoses do not meet your exact criteria, our custom hoses provide you with additional flexibility to help you get exactly what you need for your job.
Ralston Instruments tube adapters make connecting to tube fittings quick and leak-free, all without a wrench
Traditionally, tube fittings have been designed to be made up at 1.25 turns. However, when they are disassembled and reassembled they often get tightened beyond 1.25 turns. Over time, this pattern of excessive tightening results in the front ferrule digging into the tube and making it bulge out in a way that puts excessive wear and tear on the fitting. Not only does this cause leaks but it also makes the nut harder and harder to spin thus reducing the life of the fitting. Now there is a better way to connect to a tube fitting.
Ralston Instruments Introduces 90 Degree Elbows
Ralston Instruments introduces new 90 Degree Elbows. Connect to transmitters in hard to reach places.
