New Construction Pipeline Inspection Services

MISTRAS offers a robust suite of available non-destructive evaluation (NDE) inspection services, ranging from traditional NDE to high-tech pipeline crawlers.

Our key pipeline NDE services include:

Our pipeline NDE solution help us to accurately identify locate, and size girth material weld defects, monitor discontinuities over successive inspection intervals, calculate growth rates of discontinuities, and plan repair or replacement activities.

We supply highly-trained and certified NDE technicians, who can also perform pipeline inspection services with RT and UT external crawlers.

MISTRAS Automated Radiographic Inspection (ART) Pipeline Crawler

MISTRAS has designed and manufactured a computed radiography (CR) crawler for pipeline inspections in hard-to-reach areas, complete with the ability to inspect lines through insulation and those with product flowing through them.

The crawler can detect defects as small as .031”, at higher speeds than traditional inspection techniques. The unit excels in lieu of inline inspection runs, as its non-intrusive application allows it to inspect unpiggable lines.

Other benefits of the ART Crawler include:

  • Real-time inspection data
  • Unlimited range, restricted only by obstacles on the pipeline itself
  • Detection of easily missed inconsistencies, such as shallow pits or moisture content
  • DICONDE-compliant images
  • No insulation stripping or re-installation
  • Single X-ray can monitor large portion of pipeline

Pipeline Integrity Assessment Services

After your pipeline has been in operation for several years, MISTRAS performs pipeline integrity inspections & assessments to ensure it continues to operate safely. Our pipeline integrity assessment solutions include:

  • Aboveground Survey Direct Assessments
  • Pipe-to-Soil Potential
  • Corrosion Measurements
  • Coating Inspections
  • Inline Inspection (ILI) Services
  • AUT Inspection of Dead Legs
  • Remote Auditing
Inline Inspection (ILI) Services

MISTRAS provides inline inspection services for small-, medium- and large-bore pipelines, including those that were previously considered unpiggable. We use combination inspection tools with high-resolution sensors in both free swimming and tethered configurations. Our tools identify and record all pertinent pipeline data, including metal loss defects and pipeline-specific geometry features.

Pigging refines the inline inspection process and produces accurate data. Our technology enables us to determine whether damages are to the internal or external pipe body wall, offering a high level of insight to enable more effective maintenance planning. Though inline inspection often requires multiple runs by multiple contractors, our tools can gather all relevant inspection data in a single run, saving time and money.

Pipeline Integrity Direct Assessments

Direct assessments are used to evaluate external corrosion during pipeline integrity assessments, often performed in conjunction with inline inspection (ILI) or hydrostatic pressure testing. They are typically conducted to evaluate external corrosion, internal corrosion, and stress corrosion cracking (SCC). Direct assessments consist of reviewing pipeline operating data, indirect and direct examinations, and a post-assessment evaluation to determine the appropriate action.

MISTRAS supplies pipeline integrity experts to perform external corrosion direct assessments (ECDA).

ECDAs are used to comply with government and regulatory body regulations. These regulations require pipeline operators to gather more definitive information regarding the extent and types of damage in the piping system in a timely fashion after internal defect has been found.

MISTRAS takes advantage of our wide range of available NDE solutions and pipeline engineering expertise to complete direct assessments.

Searching for internal and external corrosion, stress corrosion cracking (SCC), long-seam anomalies, and third-party mechanical damage, MISTRAS completes multiple NDT technologies and other tests, including:

  • Chemical Analysis
  • Magnetic Particle (MT)
  • Penetrant Testing (PT)
  • Radiography (RT)
  • Soil pH Level Recordings
  • Topographical Land and Land-Usage Categorizations
  • Ultrasonic Testing (UT)
  • Visual Inspection (VT)

All of our pipeline integrity reporting is performed in the field using electronic reporting formats that enable the down loading of electronic data from our inspection equipment to our field computers. Our report is standardized, concise, and thorough.

Hard-To-Reach Pipeline Access and Inspection Solutions

Many pipelines, especially offshore subsea and buried lines, are difficult to access for regular inspection and maintenance, but long intervals between inspections can allow damages to worsen.

MISTRAS provides unmanned drones, trained divers, inspection crawlers, and condition-monitoring solutions to ensure that pipeline operators stay aware of their asset’s conditions at all times.

Unmanned Drone Pipeline Inspection Services

Aerial drones are useful to quickly and safely conduct pipeline right-of-way inspections in hard-to-reach areas, and as emergency response tools to pinpoint underground gas leaks with infrared sensors. Our subsea drones prevent the need to take a pipeline out of service by using high-resolution cameras, UT, and sonar, which can check for blockages in high-turbidity liquid.

Pipeline Integrity Data Management Software

Effective and accurate data management is the key to any pipeline integrity management (IM) program. Many pipeline operators rely on spreadsheets and paper files to document pipeline inspection and integrity data throughout its lifetime, but this inefficient method of data storage potentially increases the possibility of overlooking data that may predict a pipeline failure.

Through our Plant Condition Management Software, PCMS®, MISTRAS centralizes new construction inspection and pipeline integrity data, enabling pipeline operators to make more informed decisions on their pipeline maintenance.

During the pipeline integrity phase, the centralized data hub reflects the dates and types of any previous inspection, maintenance services, and monitoring data, for a complete picture of the pipeline’s integrity.

Combining PCMS’ advanced engineering capabilities with access to historical inspection data, MISTRAS works with clients to prioritize potentially high-risk problem areas.

As a OneSource asset protection solution provider, MISTRAS works with our clients to implement and execute a comprehensive pipeline IM program, including providing:

  • Engineering input on pipeline design and construction
  • NDE inspections for newly-constructed lines and direct assessments
  • Coating, insulation, corrosion mitigation, and other light mechanical services to repair and prevent defects
  • Remote monitoring systems and services to provide early warning of potential damage areas
  • Storage, organization, and analysis of all inspection and integrity data in a central inspection data management software (IDMS), utilizing a risk-based assessment algorithm custom-tailored for the properties of an individual pipeline.
Risk-Based Pipeline Criticality Assessments

Our PCMS and pipeline engineering experts work with our clients to develop asset-specific, risk-based pipeline integrity management (IM) programs. These risk-based criticality assessments help to maximize the safety and integrity of a pipeline by assessing an asset’s criticality by analyzing the probability and consequence of failure.

Pipeline risk-based criticality assessments can only be performed through the use of an advanced data management software capable of performing complex engineering calculations.

To determine an identified defect’s probability and consequence of failure, PCMS takes into account multiple factors, including:

  • Population Near the Affected Segment
  • Material of Construction
  • Pipeline Age
  • Type of Product
  • Soil Type
  • Likely Damage Mechanism(S)
  • Previous Repairs
  • Maximum Allowable Operating Pressure (MAOP)

Based off the answers, operators are able to determine how critical a repair is for the identified defect, optimizing maintenance planning.

MISTRAS’ value-added, OneSource pipeline protection programs provide an integrated, one-stop shop from start to finish. With multiple inspection, deployment, and data management solutions available during every operational phase, MISTRAS has an answer for any pipeline problem.
