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 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.
