Breakthrough pigging tech allow more than one pig launching along with standard pipe gear. Existing pipe systems alongside the installation of new lines over great distance and in extreme environments has increased demand for breakthrough pipeline equipment.

Pipe pigging system equipment is essential to remove blockages whilst also collecting sample fluids. Also, for making sure flow is maintained and corrosion minimised. Pipeline pig activities are time consuming that can interrupt production and operations.The UK oil and gas industry Technology Facilitator released a statementfor technology proposals to grow production capacity . Submitters viewed consistent flow techniques as essentail.

Cleaning up accumulated pipe liquids withpigging systems replacing conventional sphere-launching methods has improved natural-gas flow efficiencies to over than 90% from 15% in 200 miles of a high-pressure gathering system. The increased efficiencies grew capacity ...
... on two legs of the system by above 20 MMcfd and allowed operators to shift gas amongst three processing plants in the the region. This gas-flow shift grew plant throughput and reduced operating cost.

Integrity management is also inherent to maximizing pipeline equipment. The first part of two articles (OGJ, 2008) described the three steps of this procedure: Assesment, Quantification and Identification. Assessment - A simple finite-element analysis. Quantification - Ultrasonic thickness measurement and Scan B results. Step 3 - A magnetic-flux leakage intelligent pig report.

A simple economic procedure applied to NGL pipelines can help operators determine-based on the type, shape, and position of any abnormalities detected during periodic magnetic-flux leakage pigging- whether to shut the pipeline for repair or continue operations.The first part of two articles (OGJ, , 08, page 80) described the three steps of this procedure: Identification. A magnetic-flux leakage intelligent pig report and ultrasonic Scan B test identified the defect. Quantification. Scan B results use gammagraphic inspection to find the problem size and location on the pipe wall.
