Petrochemical Life Cycle - Exploration and Production

Petrochemical Life Cycle Exploration and Production

The content in this phase of the Petrochemical Life Cycle (see pages 22-23) focuses on the numerous transfer applications in the oil and gas field. Featured are the Dixon® products used within the Exploration/Production segment.

Please refer to the Dixon Product List or dixonvalve.com for specific part numbers and various other products used in the transfer and control of liquids, gases and dry materials.

Dixon's couplings and retention devices are designed to work safely for their intended use. The selection of the proper hose, coupling, and retention device, and the proper application of the coupling to the hose are of utmost importance.

Users must consider the size, temperature, application, media, pressure, and hose and coupling manufacturer's recommendations when selecting the proper hose assembly components. Dixon recommends that all hose assemblies be tested in accordance with the Association for Rubber Products Manufacturers (ARPM) recommendations and inspected regularly (before each use) to ensure they are not damaged or loose. Visit ARPMINC.com for more information.

Where safety devices are integral to the coupling, they must be working and utilized. The use of supplementary safety devices such as safety clips or safety cables are recommended.

If any problem is detected, couplings must be removed from service immediately.

Dixon is available to consult, train, and recommend the proper selection and application of all fittings we sell. We strongly recommend that distributors and end users make use of Dixon's testing and recommendation services. Call 877.963.4966 or click dixonvalve.com to learn more.
