Services Rendered

Fabrication & Installation of permanent piping modifications for the Field and Transmissions lines (4”-8”) for the Early Grove System(s) along with (11) Anomaly Verification Digs throughout the (2) systems.

Fabrication, Removal, & Installation of a permanent launcher/receiver to existing piping to facilitate pigging. Work includes, but is not limited to, removal, concrete pier installation, barrel installation, fabrication of auxiliary piping (Kicker/equalizer/source control), pipe support installation, pressure testing, drying, painting and coating, and restoration of the construction work area. These modifications are to be performed on (4) separate lines within (2) piping systems (Field & Transmission); one is high pressure, the other is low pressure. Low Hydrogen Welding included in this Scope of Work.
