Smith Flow Control’s Key Interlocks for PIG Launchers and Receivers
Interlocks safeguard against improper process execution
Smith Flow Control’s interlocks are single or dual-keyed mechanical locking devices used to control the sequence in which process equipment may be operated. Using a ‘key transfer’ principal, operational control over safety-critical processes can be ensured. The use of interlocks is recommended by a number of internationally recognised standards for specific process applications, causing wide acceptance by many of the world’s oil, gas and chemical majors. SFC’s products are used on some of the longest pipelines in the world.
SFC interlocks are constructed of stainless steel and lubricated for life. Each interlock is quickly installed on any standard sized valve or associated equipment with no modifications required. SFC also offers customised solutions to customers with specialised requirements.
