AUTOMATED PIG LAUNCHER SYSTEMS

WeldFit specializes in the design, engineering, manufacturing and quality testing of automated pigging systems that can be utilized to perform four separate pigging functions: liquid recovery, cleaning, batching and in-line inspections. The SureLaunchTM automated pigging system can launch any type of pig individually at pre-set launch intervals through the use of a logic-driven control system and an electrical drive system. The horizontally oriented automatic launcher design is loaded with multiple pigs in one loading operation that allows the launching of a single cleaning pig, batching pig or spherical pig for both liquid and gas pipeline service applications.

KEY FEATURES & BENEFITS:

  • Horizontal design eliminates access platforms and lifting equipment to reduce safety risks, transportation costs and field installation costs
  • The mechanical launch mechanism ensures pig launches in high and low flow conditions
  • The flow-through barrel design of the automated pigging system removes the need to open and close valves for each pig launch, resulting in an increase of the valve operating service-life and a reduction of maintenance costs, environmental emissions and safety risk exposure
  • The electric drive system can be powered by 115 VAC or 24 VDC Class 1, Division 1 & 2 compliant power to eliminate supply gas, supply gas treatment and emissions
  • Launch system is controlled by drive system that allows any type of pig to be launched to meet operator’s specific pigging requirements
  • Standard automated pig launcher is designed to accommodate up to seven cleaning pigs or length of typical in-line inspection tools
  • Standard receiver is designed to accommodate up to eight cleaning pigs or length of typical in-line inspection tools
  • Primer coated ready for customer desired paint system or painted to customer’s paint specification
  • Quick opening closure standard on all units
  • Designed with the appropriate quantity and size of nozzles for vents, pressure gauges and drains
  • Data Package provided for code compliance
  • Hydrostatic pressure tested in accordance with the applicable codes
  • All units are skid mounted
  • Ethernet/IP address for remote access capabilities
  • Designed to applicable safety design factor
  • Inspected and designed in accordance to the applicable pipeline codes (B31.8, B31.4, B31.3, Sec. VIII Div. 1)

OPTIONS:

  • Semi-automated capabilities without logic-driven controls
  • Semi-automated systems can be equipped with electric drive motor or can be manually operated when electric power is not available
