Sewer network inspection services

Among the various types of activities in the industrial field, inspection has a special place in the industry. The inspection process includes checking and ensuring the quality of manufactured products, as well as awareness of damages to industrial facilities during operation and prevention of crises in other industrial processes.
Facility inspection or in-service inspection or, better said, operational inspection is a tool for collecting data related to the status of industrial facilities in order to prevent crises or heavy overhaul costs by knowing them with the help of an appropriate preventive maintenance program (PM). Inspection in industrial facilities has various types, from destructive inspections and tests to non-destructive tests and inspections.
In non-destructive inspections (NDT), which do not damage or harm the inspected facility, there are various types, including visual inspection (VT), liquid penetrant testing (LT), magnetic particle testing (MT), radiographic testing (RT), ultrasonic testing (UT), and phased array ultrasonic testing (PA), etc.
In the water and wastewater industry, inspection is non-destructive and visual, which is why it is sometimes called Videometry. Videometry is the measurement and visual inspection (along with recording images and video) and the collection of other information about the dimensions, size and quality of defects and damages by recording their location.
In general, with the advancement of science and industrial achievements and the need for greater accuracy in the production of products and the quality of services on the one hand, and the improvement of human safety standards on the other, the need to use robots has become more and more felt in the industry. In other words, in situations where either inspection by humans is not possible due to access restrictions, small dimensions, lack of sufficient light, etc., or due to the presence of hazards such as toxic and explosive gases, it is not safe for human work, the robot replaces the human to complete the inspection operation robotically.
When performing robotic videometry operations, by using various sensors, other parameters such as temperature, pressure, slope, and double track width can be measured. Videometry in the water and wastewater sector is also performed with the help of other tools for various purposes. These tools include cable or spring inspection cameras (PushRod) as well as manhole inspection cameras, which are known as quick view and zoom cameras in the sewage sector, and videometry using deep well inspection cameras in the water sector.

Sewer Inspection Robot

The sewer network inspection robot is one of the most practical tools in the field of sewer inspection, which is used continuously and continuously in the sewage field today, because on the one hand, direct human inspection in these facilities is not recommended due to the presence of dangerous gases, and on the other hand, in many parts of the sewer network, human visual inspection without equipment is not possible due to the small diameter of the facilities.

The most important purpose of videometry in this field is the maintenance of wastewater networks, because inspecting the lines and their minor repairs prevents serious damage to the wastewater lines in the long term and even the contamination of groundwater. In other words, the only tool for collecting information on the network status for planning a preventive maintenance program is these videometric inspection robots. According to international and domestic laws and standards such as the WRC standard and the 677 regulation of the Management and Planning Organization, wastewater collection networks must be inspected and videometrically inspected annually. Also, by inspecting new wastewater lines, the health of the wastewater network can be fully ensured before operation.

Company Services
Kavosh Mechanized Technology Company, as the most experienced and largest videometry contractor in the country with several thousand kilometers of videometry experience in all parts of the country, with several videometry robot devices manufactured by Kavosh Company, standard software, an experienced and specialized executive team in the form of several videometry teams, is ready to provide videometry services for sewage network lines in various dry and operational conditions and in various diameters from 125 to 2200 mm to its customers.

FloatBot Floating Robot

In high-diameter sewer lines where the amount of fluid flowing in the pipe increases, ordinary inspection robots do not have the required efficiency for two reasons: first, the strong flow of fluid makes it difficult for the robot to control the puller, and second, the large volume of water increases the rate of robot failure and reduces performance. Therefore, robots that can float are used in this category of inspections.
This company also provides all sewage inspection and videometry services in transmission tunnels with diameters of 1000 to 3000 mm and containing fluid that cannot be blocked or diverted. Also, the mechanized exploration of the technology is aimed at providing more comprehensive information on the condition of such lines in cooperation with foreign companies that produce high-tech floating systems.

With the possession of a floating inspection robot, the company has the ability to provide videometry services for large diameter lines using a floating videometry camera.

Quick View Camera (Zoom Camera)

Quick View cameras, also known as manhole cameras and zoom cameras, are another visual inspection tool for quick inspections of sewer lines. These cameras also have a laser rangefinder sensor to measure distances to obstacles in the path.
The Quick View camera has a zoom capability of 10 to 70 meters and is sometimes equipped with an anti-shake system during video recording to clearly display objects. The operation of this camera is very simple, fast and easy and is very suitable for quickly checking the overall condition of sewer lines.

Cable Inspection Camera

Push rod cameras or branch cameras are another visual inspection tool in the sewage field. Due to the smaller diameter of these cameras compared to inspection robots, they can be used in pipelines with small diameters and also curved paths due to the flexibility of the camera movement. Depending on whether the push rod camera is rotatable or fixed and axial, the efficiency of this inspection device varies.
The relative advantage of these cameras compared to inspection robots is that they are very easy to carry, do not require a specialist operator, and are also very affordable. Push rod cameras can usually be used in sewage networks up to a maximum diameter of 350 mm. The disadvantages of push rod cameras include the inability to measure temperature, slope, pressure, and laser measurements compared to network inspection robots.

Videometry equipment in the water sector

Deep Well Videometer Camera

Deep well videometer camera is one of the most widely used equipment for examining the condition of water wells. Today, this device has been able to provide useful videometer information, helping well specialists a lot.
Well videometer cameras, with information such as the complete condition of the pipe wall, the type of sediments inside the well, and the complete structural condition of the well at different depths, have also provided more accurate decision-making for specialists in this field. In addition to filming and photographing, these cameras have the ability to measure the physical and chemical characteristics of water such as water hardness, salinity, pH, and also examine the types of sediments in the well.
Water well videometer cameras are also produced by this company in different classes, including single-axis camera, single-rotation camera, and four-camera.
