Fossil-Fuel-Refinery

Fossil Fuel Services

This is a challenging time to own and operate fossil fuel production, refining and power generating facilities. The majority of facilities are over 30 years old, and almost all were originally designed for much lower throughputs. This aging and stressed infrastructure can create significant risks to personnel, the environment, worker safety and profitability. In addition, environmental requirements, reduced maintenance budgets, staff reductions, and fewer and shorter outages further complicate an already difficult operating environment. WaveTrue understands that effective non-destructive equipment integrity inspection is one of the critical keys to a facilities long-term viability. Our existing technologies fit perfectly into an inspection program that supports smooth operations with no unplanned downtime or dangerous equipment-failure-related upsets. Not only are our existing technologies a perfect fit for the industry, we are constantly working with our clients to refine and develop inspection services that address the dynamic needs of today’s complex facilities.

Inspection Services

External

WaveTrue’s External Inspection Method is similar to RADAR in the way that it works. Electromagnetic waves are launched into the space between the pipe and jacketing or casing using pipe surface attached injectors and a receiving probe. The waves travel down the tube or pipe and reflections occur at sites of anomalies such as corrosion, water, coating or insulation damage. The location of the anomaly is determined and data at the location is processed in order to further characterize the anomaly. The range and resolution of the measurement are interrelated and depend on factors such pipe and casing/jacketing diameter and insulation material, the particular mode used for the inspection (TE or TM) and the frequency scan range and step size used. The types of anomalies that can be detected are corrosion, water, coating and insulation or jacketing/casing damage and electrolytic shorts. In general, any anomaly that would cause a change to a uniform condition within the external pipeline system could be detected if its size is such that its response is above the threshold for the particular anomaly. WaveTrue is continuously improving this tool by implementing new methods for data acquisition and analysis and by evaluating new equipment as it becomes available.

Internal

WaveTrue’s Internal Inspection Method is also similar to RADAR in the way that it works. Electromagnetic waves are launched into the hollow space of a tube or pipe using a cylindrical stub antenna. The waves travel down the tube or pipe and reflections occur at sites of anomalies such as sludge or cracks. The location of the anomaly is determined and data at the location is processed in order to further characterize the anomaly. The range and resolution of the measurement are interrelated and depend on factors such as the tube or pipe diameter and its material, the particular mode used for the test (TE or TM), the frequency scan range and step size used, and the product flowing in the line. The types of anomalies that can be detected are sludge or plaque buildup, water in a natural gas pipeline, cracks, and wall loss due to corrosion or other means. In general, any anomaly that would cause a change to a uniform condition within the pipeline could be detected if its size is such that its response is above the threshold for the particular anomaly. WaveTrue is continuously improving this tool by implementing new methods for data acquisition and analysis and by evaluating new equipment as it becomes available.
