Overview

During the 41+ years that we have been in the non-destructive testing (NDT) and non-destructive evaluation (NDE) field, JANX built and maintained a reputation for reliable, responsive service.

For the 785 clients they worked with during the last several decades, that devotion to excellence, coupled with extensive experience and knowledge, has consistently resulted in the precise, accurate, and timely data they needed to effectively manage and protect their assets.

Today, JANX provides NDT and NDE in 43 of the country’s 50 states. And with every project, on every scale, we stand behind our work.

The JANX Difference

  • The capacity to staff up quickly—we report to work sites within 24 to 48 hours of service calls, often in less time.
  • A full-time staff of mechanics who build onsite darkrooms and retrofit our trucks for your project’s requirements to make sure you get prompt, effective service.
  • 350+ vehicle fleet with no vehicles older than five years old, so you can count on us to get where you need us, on time and ready to work.
  • Conventional and cutting-edge evaluation methods, including the use of proprietary and highly advanced technologies.
  • Knowledgeable technicians and team leaders with an extensive understanding of our customers’ needs and the industries we serve.
  • A relationship-based approach to business—many of our customers have been with us for years, and several have been returning to JANX since we were founded in 1981.
Products & Services
Radiographic NDT Testing

Radiographic Testing, one of our core areas of expertise, calls for using X-rays or gamma radiography to perform a full volumetric inspection to validate the integrity of welds and other components. Radiography is one of the oldest and most widely used non-destructive testing methods.

In most cases, radiographic NDT inspection is used for the testing of welds on pipelines, pressure vessels, piping, storage containers, and structures. JANX’s qualified radiographers interpret radiographs to applicable codes and standards such as API, ASME, and AWS while complying with required customer specifications.

JANX regularly provides high-production weld inspection services on major pipeline construction projects using both Real-Time Radiography and Conventional Film Radiography services, including internal crawlers.

Radiography is performed by applicable NRC, agreement states, or jurisdictional requirements.

Available radiographic equipment includes:

  • Gamma Sources – Iridium 192, Selenium 75, and Cobalt 60
  • External X-ray Tubes – 150kV to 300kV and can be used for various applications.
  • Internal X-ray Crawlers – 100kV to 300kV with pipe diameter ranges of 6” to 56”

JANX utilizes a wide range of radiographic techniques including:

  • Conventional Radiography (RT)
  • Gamma Radiography
  • Computed Radiography (CR)
  • Real-Time Radiography (Digital RTR)

Benefits:

  • Provides a permanent record: Ensure compliance with codes and standards
  • Allows for full volumetric inspection: Allows customers to make informed decisions about weld or component integrity.
  • High probability of detection: Can detect porosity, inclusions, cracks, and voids in the interior of welds.
  • Provides accurate location of defects: Customers can quickly proceed with repairs, avoiding costly project slowdowns.

We are there when you need us

Because we’re equipped to mobilize radiographic testing services across the United States, our customers can get their inspections done whenever and wherever they need them. That includes pipeline operators working in remote environments or extreme conditions. Our technology and more than 35 years of experience mean customers can rely on us for thorough, detailed, and rapid inspection results.

Magnetic Particle Testing Service

Magnetic particle testing (MPI) detects surface and slightly subsurface discontinuities in ferromagnetic parts (susceptible to magnetization) such as carbon steel, iron, nickel, and some of their alloys. The process involves inducing a magnetic field on a component, and dry or wet magnetic particles are applied.  At an area where there is a flux leakage (or interruption of the magnetic field), the particles visibly gather, and we evaluate them to applicable codes, standards, and client specifications.

We offer MPI for a wide range of applications, including testing services for welds, piping, and other components such as shafts and structures.

Magnetic Particle Testing techniques include:

  • Dry powder inspection – Multiple colors available for high color contrast.
  • Wet non-fluorescent inspection
  • Wet fluorescent inspection

MPI is also a valuable means of checking for cracking, including:

  • Stress corrosion cracking
  • Fatigue cracks
  • Corrosion-related flaws
  • Surface and near-surface discontinuities

Benefits:

  • Cost-effective
  • Quick inspection
  • Portable
  • Reliable in critical defect detection
  • Our highly trained technicians can mobilize portable inspection units (AC or DC yoke) anywhere in the United States.

Wherever You Need Us

Because we’re equipped to mobilize testing services across the United States, our customers can get their inspections done whenever and wherever they need them. That includes pipeline operators working in remote environments or extreme conditions. Our technology and more than 35 years of experience mean customers can rely on us for thorough, detailed, and rapid inspection results.

Liquid Penetrant Testing NDT

Liquid penetrant (PT) testing of materials is an effective non-destructive testing (NDT) technique for detecting surface defects. It’s commonly used to inspect a wide range of materials and welds where the properties of the material limit the use of other NDT methods.

During this process, the penetrant is applied and allowed to dwell or soak for a determined amount of time. Once the part has had ample time for the penetrant to dwell it is removed carefully, and the developer is applied. The penetrant bleeds through the developer, which produces a visible or fluorescent indication that we evaluate to applicable codes, standards, and client specifications.

Liquid Penetrant Testing techniques include:

Type I – Fluorescent penetrant examination

  • Method A – water washable
  • Method C – solvent removable

Type II – Visible penetrant examination

  • Method A – water washable
  • Method C – solvent removable

Benefits:

  • Mobile
  • Cost-effective
  • Portable
  • Sensitive to critical defects
