How The Pipeline Inspection Crawler Camera Works

Pipeline Inspection Crawler Camera is suitable for surveying and testing inside residences, small-scale commercial establishments, special factories and municipal engineering pipelines, including slender, narrow and curved transformation pipelines that cannot be accessed by other inspection instruments. Its simple operation, powerful, wide application.

Pipe Inspection Crawler Camera is composed of an integrated main controller, a flexible push rod cable tray, and a high-precision and durable camera. The flexible push rod cable is used to push the front camera into the pipeline, and the camera is combined with an image automatic return function and integrated. The LED lighting, preview and record the internal image of the pipeline, so as to achieve the purpose of detection. The Pipe Inspection Crawler Camera is used for quick video survey and acceptance of sewers or pipe networks, and census evaluation. The PipeSight Pipeline Video Interpretation Report Software can be used to interpret the inspection videos, generate professional inspection reports and intuitive electronic maps.

What Is The Working Principle Of The Rebar Detector?

Portable and fast-response rebar detector  can quickly detect and measure concrete depth and rebar diameter and position over a large area. This method of non-destructive testing is especially useful for repair and restoration work.  How It Works Concrete element sizing or rebar placement is best done using two techniques — pulsed magnetic induction or electromagnetic waves. 
It is advisable to use rebar detector before drilling, sawing or coring from ready-made reinforced concrete at depths of up to 300 mm. The combination of magnetic induction / radar technology with three-dimensional scanning allows you to detect voids, as well as foreign inclusions, including: metal and plastic pipes; fiberglass cables; wood. Based on the test results, the quality of concrete is checked, including an assessment of the curvature of the element, the uniformity of density, the depth of the reinforcement. Rebar detector can also function as wire detectors.  Typical concrete reinforcement locator device: Ground penetrating radar that uses radar pulses to generate an image. Receiving and transmitting antenna. Unit for transformation of magnetic impulses into a stereoscopic image. Power supply. Screen for viewing scan results. The flow of electromagnetic radiation is used to register reflected signals from internal structures that have different density indices than the base material. The radar method uses the effect of reflection of waves that meet an obstacle in their path in the form of reinforcing rods or hidden pipes. Technological Capabilities To ensure the structural performance and durability of reinforced concrete, the location of reinforcement and its depth are critical variables. Therefore, it is important to establish the applicable range, the characteristics of the measuring device, the measurement procedure, and the necessary precautions. 
When using reinforcement locators in concrete, which implement the electromagnetic induction method, the depth of the reinforcing bars usually does not exceed 200 mm, and the radar depth does not exceed 100 mm. The height and nature of the relative position of the reinforcement rods do not matter. The main standard sizes of induction locators of domestic and foreign production are adapted to the detection of steel rods with a diameter of 3 ... 50 mm. 

What Is A Pipeline Underground Water Leak Detector And How To Use It?

In modern industry, pipeline laying is essential. Whether it is ordinary water supply, heating mains or oil pipelines, whether in daily life or in industry, pipeline communication is ubiquitous.
The use of modern materials makes the pipe very reliable, but nothing is permanent. All materials have a service life. And we don’t know what factors will affect its durability.
Risk of leakage
Leaks are one of the most unpleasant water supply failures. Sometimes, when water gushes from the ground, it can be confirmed visually, but sometimes it is impossible. In order to eliminate the accident, it must first be accurately detected.
In the past, in order to determine the leak, people had to dig the ground in the so-called accident area, but this did not always bring the expected results. These activities are not only labor intensive, but also cause a lot of trouble to the people around them-water supply interruption, road blockage, etc.
Sometimes the leak is so small that no one knows. To eliminate such failures, you need to spend a lot of time and effort.
The slight drop in pressure in the system is the first sign that not everything on our production line is in order. Over time, this will develop into a serious leak, so it is necessary to take measures to eliminate the leak as soon as possible.

Leak detection method
Several methods can be used to determine the location of the leak:
If a metal pipe is used, use a signal generator to determine the fracture of the water pipe. It is installed on the highway and sends signals and is received by the receiver. Nowadays, plastic systems are mainly used, so this method is of little significance.
You can fill the pipeline with a safe gas mixture. Usually 95% nitrogen and 5% hydrogen. The gas will escape from the cracks, seep into the soil, asphalt or concrete layer, and then escape the ground. Viewed from above, the leak was determined by the gas analyzer, and the gas analyzer determined the damage.
Two cylinders can be used to determine the breakthrough of the water supply. They are inserted into the test area from both sides. Air is forced into the pipe. If the pressure drops, the damage in the area between the cylinders remains unchanged-check the next area.
You can also use a special device-a underground water leak detector. Regardless of the pipeline laying conditions, the device can detect leaks with an accuracy of 1 m to 10 cm.
The working principle of the Underground Water Leak Detector is based on the sound vibration of the test soil, liquid or pipe wall. These vibrations are converted into electrical or acoustic signals, which are monitored by the operator.
The signal can be sent to the computer monitor via a cable or wireless channel.

A more stringent underground water leak detector can not only detect the fault, but also determine its degree, so that the fault can be eliminated with minimal loss.
