From extreme temperatures to flammable and explosive environments, electrical connectors used in oil and gas applications face a number of challenges. So, what should be considered when choosing connectors that can overcome these challenges and keep these applications running at peak efficiency?
Envirnmental factor
When choosing a connector, the first factor to consider is the different areas the connector will be used in.
In the Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR), Zone 0 is defined as a persistently explosive atmosphere, Zone 1 means a frequently present explosive atmosphere, and Zone 2 means a rarely explosive atmosphere. The UK Health and Safety Executive (HSE) explained that "the main purpose of zoning is to facilitate the correct selection and installation of equipment for safe use in that environment, taking into account the properties of the flammable materials that will be present."
In the worst case, if the current through the connector comes into contact with flammable liquids and gases in the environment, it can become a source of ignition. Therefore, all connectors used in explosive atmospheres must comply with the IECEx international standard, which regulates the installation and use of electrical equipment in these environments.
Connector Features
Next, consider any additional features that can improve efficiency. For example, powering down a system to disconnect a device (possibly in a hazardous environment) can be time-consuming and negatively impact productivity. This can be overcome by installing connectors with thermal disconnect capability, allowing customers to disconnect and reconnect devices without shutting down the entire system.
Another way to maximize efficiency is to consider the ease and speed of connector assembly. PEI-Genesis offers connectors that can withstand the challenges of the oil and gas industry, such as the Trolex Falcon 25 series, which is known for its quick-mating and locking mechanisms that take only a few minutes to assemble. The company is also an ATEX certified assembler for Amphenol Star-Line EX and Amphe-Ex, which are among the most popular oil and gas connectors due to their rugged design and plethora of configuration options.
