Explosion-Proof TV Inspection

We can safely inspect sewers where Volatile Organic Compounds (VOCs) are present. National Industrial Maintenance offers a full line of explosion-proof video inspection services for petrochemical and other industries. All equipment used is listed and labeled for explosion-proof operations. Using flame path technology and inert gas pressurization, we are able to safely inspect pipelines with Class 1, Division 1, Group C & D atmospheres and ATEX Zone 1 and 2.

Explosion-Proof Camera Mounted Tractors

Specialized Maintenance uses a wide range of camera transports to inspect pipelines and confined spaces that require an explosion-proof rating. These include tractors, referred to as crawlers, with variable speed controllers. Our explosion-proof video cameras are mounted on specially designed transports that allow for the thorough and safe inspection of jet fuel lines, natural gas pipelines, oil and hydrocarbon transmission lines, or any other pipeline with explosive atmospheres. All cameras produce sharp, full color, quality images

Our larger crawlers are steerable and are used in pipelines in which a person cannot enter. The smaller crawlers are capable of traveling and inspecting up to 1,000 linear feet of pipeline from a single entry point. identifying oil sheens on the water.

Pan & Tilt Camera Systems

The operator points the camera and lighting assembly at the area to be inspected and can then pan, as well as rotate, the camera head a full 360 degrees. These important features enable us to provide a very detailed inspection of interior pipe walls, borehole and drilled shaft walls, or any other confined area. The resolution and image quality of our cameras is second to none in the industry and are capable of even

Deep Tunnel Inspection Camera System

The deep tunnel inspection camera is specifically designed for the inspection of very large diameter subsurface tunnels. This base system can be adapted to meet the specific needs of each project. This system is completely explosion-proof for Class 1, Division 1, Group C & D environments.

Mini-Cameras Inspections

Our operators use push rod, mini-cameras to inspect small diameter pipelines. Pipelines from 2 inches up to 500 feet in length can be inspected with these camera systems. Using specialized Twin-View mini-cams we can inspect 4 inch to 8 inch pipe. These units are rated for working in Class 1, Division 1, Gas Groups C & D, Temperature 3 Environments. We also have the capability to inspect 1 inch to 4 inch pipes using mini-cameras that are intrinsically safe and rated for working in Class 1, Division 1, Gas Group A, Temperature 6 Environments.

Common uses are jet fuel transmission lines, gas pipelines, propane storage caverns, boreholes, and others. This system uses a self-upright positioning camera. This feature insures the picture always appears upright on the screen even if the camera should flip over.

WinCam Software

Our WinCam software produce the most sophisticated – yet user friendly, data collection, analysis reporting and archiving software available in the industry. With this technology, we can provide the most comprehensive reporting possible, including;

• Data Collection
• Video Capture
• Picture Capture
• Video Sequence
• Manhole Inspection/Reporting
• Data Importing/Exporting
• Text Capture

Project information, pipe section observation and photos can be directly analyzed on screen. Data is recorded on our computer hard drive and can be stored on DVD or any hard drive storage device and can be retrieved in seconds. To make engineering decisions even easier, a wide variety of statistics, manhole and pressure test protocols are available.

Our experts have helped petrochemical and other facilities across the country comply with EPA regulations. Working under the direction of your engineers, we can handle all or any part of your sewer correction program, from beginning analysis through the rehabilitation of your entire system Our services include Infiltration Control, Analysis, Sewer System Evaluation Surveys, GPS Mapping, Manhole Inspection, and Archive Data Collection.

All operators are factory trained and authorized to operate our camera systems in pipelines with explosive atmospheres.
