Blanketing gases such as nitrogen and carbon dioxide are commonly used as protective atmospheres in storage tanks and vessels containing flammable liquids or solids to prevent fire or explosion. These gases are also used to maintain a dry inert atmosphere to prevent corrosion of cleaned piping and vessels.
Whether you have a fired heater, furnace or pipeline that has become dirty or new piping that needs cleaning, we offer a complete line of cleaning and drying services that can be tailored to each of your individual projects. An engineering analysis will determine which option will meet your cleaning and dew point specifications in the most cost-effective way possible.
Leak Detection -
Damaged pipes not only leak gas but profits and productivity. That’s why we provide a comprehensive suite of accurate and reliable technologies and services that are designed to fit the needs and budget of your business, and are backed by the best experience and reputation in the industry.
Pressure Testing -
New piping and vessels often need their mechanical integrity proven prior to use. Existing vessels and piping can require a similar test as part of an asset integrity program or for re-rating at a higher pressure. We offer both pneumatic testing and hydrostatic testing methods to satisfy these needs. Pneumatic Pressure Testing of equipment is undertaken by safely using air or nitrogen.
Tool Propellant -
Tool propellant is used for pigging with pressurized nitrogen gas as the propellant. Inline inspection tools can also be pushed through pipelines. Also, Pneumatic pressure testing of equipment is undertaken by safely using air or nitrogen.
Praxair nitrogen-assisted displacement provides a safe, fast and inexpensive means of removing product from a pipeline, whether for repair, product changeover or for product recovery when a pipeline is deactivated. In a single step, product is removed and the line is left dry and inert. Whether the line contains natural gas, crude oil, gasoline, diesel, liquid petroleum gas, ethylene or other liquid or gases, our detailed analysis of the line profiles and project conditions allows for the most efficient displacement.
We use nitrogen to safely purge potentially explosive fuel and air mixtures from vessels, transfer lines and equipment. Crude petroleum pipeline is one of the most common examples where purging and pigging operation is done by use of nitrogen.
Temporary Supply of Nitrogen, Oxygen & Argon -
When your current supply of industrial gases are unable to meet the flow, pressure or temperature of your temporary requirements, or your supply has been interrupted with a fleet of pumpers, vaporizers, transport tankers and tube trailers, we can help satisfy your temporary supply needs.
