Remote Visual Inspection (RVI) is a technique to visually inspect tube. RVI can be useful to obtain information about defect geometry and the possibly present degradation mechanisms in a tube. For more information, please visit http://www.dacon-inspection.com การตรวจสอบทางสายตาจากระยะไกล (Remote Visual Inspection – RVI) เป็นเทคนิคที่ใช้ในการตรวจสอบท่อขนาดเล็กทุกประเภทด้วยการมองเห็น RVI ไม่สามารถบอกความลึกของจุดบกพร่องได้ แต่มีประโยชน์ในการหาข้อมูลเกี่ยวกับรูปร่างของจุดบกพร่องและการเสื่อมสภาพที่เกิดขึ้นในท่อขนาดเล็ก ซึ่งจะสามารถถ่ายภาพจุดบกพร่องได้และสามารถบันทึกวิดีโอรูปท่อขนาดเล็กทั้งท่อได้ ดูข้อมูลเพิ่มเติมได้ที่ http://www.dacon-inspection.com

Remote Visual Inspection
• Remote Visual Inspection (RVI) is a system of using remote controlled cameras to
inspect hard to reach areas that are otherwise inaccessible.
• Some cameras are suitable for short distances and other more powerful cameras can
crawl many meters into pipelines. Both small and large cameras offer excellent visual
inspection capabilities and are widely accepted inspection techniques.
• In this presentation you will learn about which camera is suitable for which application
and will find a visual representation of the results each camera can perform.
• All cameras come in different size and length variations to accommodate most
requirements.
• Camera limitation can depend on the object being inspected and for pipelines it can
be restricted by the number of bends that need to be navigated.

Dacon Video Probes
Dacon has a wide range of video probes ranging in size from 7mm camera heads up
to 10mm camera heads.
Dacon Video Probes come with varying lengths of control cables ranging from 3 meters
in length up to 10 meters in length.
Dacon stocks the largest selection of video probes in Asia and we have cameras with
both fixed heads and also special articulated heads that can look in all directions
vertically and horizontally.
Video probes are suitable for inspecting small piping and tubes as well as inspecting
inside mechanical devices and machine engines which are hard to reach. All have
electronic image capturing capability and real time video viewing capability.

Dacon-XL Vu Camera
DACON XL-Vu video scope contains a 6.1 mm camera head with flexible stainless steel
cable with a 4.5 meter length. XL-Vu is suitable for small piping/tube inspection and
mechanical device s, machine engines and gas turbines. It is particular useful in the
aviation industry for detailed inspection of engine parts and the energy industry for
inspection of turbines.
XL-Vu is able to inspect in all directions using an articulated head controller.
XL-Vu runs from its own power source and there is no need to connect to computer for
recording video and picture as this is done within the unit itself. Image capture, video
capture and real time video viewing are all standard features.

Dacon Micro Camera
Dacon Micro Cameras offer high resolution images for larger pipeline diameters. As the
camera is larger and less controllable than the Dacon Video Probe it is therefore best
suited to medium diameter pipelines of 4” to 10”.
The Micro Camera is housed inside a tube that can be pushed into the pipeline. The
housing has LED lights surrounding the camera which allow the pipeline interior to be
flooded with light and allow for very clear imagery. The advantage over the video
probe is the additional light and higher definition pictures .
The camera runs from its own power source and is connected to a computer for
recording video and images. There is a restriction with how many bends the micro
camera can pass inside a pipe (generally a maximum of 2 bends).

Dacon Special Purpose Cameras
• Dacon special purpose cameras are custom made solutions tailored to meet specific
client requirements.
• An example is special long range crawler systems for penetrating many kilometers
inside large bore pipelines and tunnels.
• Another example is a custom built camera that mounted on a helium balloon to float
up and down inside the circular legs of an offshore oil platform to allow for close visual
inspection in an otherwise inaccessible area.
• All requirements can be met and built with the wide array of in-house expertise and
engineering capabilities at Dacon.

Dacon Explosion Proof Cameras
• These cameras have specially designed housings for the video camera and
electronics to ensure that they meet ATEX standards for explosion proof environments.
• Various camera systems are available both for onshore and offshore environments
covering all industries.
• High definition results available by video capture and for live viewing via computer
screen

Dacon Video Pig
• The in-line camera inspection pig is a unique instrument, which allows you to see the
inside of your pipelines.
• You can determine the quality of internal coating, check T-bars, internal corrosion,
valves and valve seats, leakage or verify inspection data.
• The camera inspection pig is also used to check the effectiveness of cleaning
programs. And identify blockages and other non conformities inside a pipeline.
• Unique in its kind, the system is 100% autonomous; no umbilical is required, so unlimited
lengths of pipeline can be inspected.
