Leakage of pipelines and pressurized fittings
Pressure leakage Online Leak sealing is a way of eliminating leakage in pipelines and pressure equipment during the production process, thereby eliminating the loss of capital that can be caused by unintended shutdown or prolonged The repair time was prevented by the imposed set.
Alborz Petro Idea Toos is proud to have successfully operated pressure-relief operations in a wide range of pressures (Vacuum to 300 bar) and temperatures (0 ° C to 520 ° C).

Some very leak-proof materials:
• ValvePacking: This method is the most commonly used pressure-relieving method applied to types of industrial valves with leakage problems.
• In this technique, which is found in many cases, without the need to shut down or isolate the milk, it is only by direct injection of a special SealantCompound that is very similar to the original sealant used in the milk itself, in a short time Solved the problem.
• Flange Joint Leaks: There are many different types of flange leaks available, depending on the working conditions at the pressure and temperature and the distance between the two flanges, the “gap” can be used. In cases where the gap between the two levels of the “gap” flange is less than 8 mm, a wiring harness can be used. This method is especially effective in lowering the pressure.
• In other cases, different types of two-piece or three-piece clamps can be used, which are designed according to the available geometry and pressure and working temperature.
• Elbow Leaks / Weld Leak / Pinhole: This type of leakage can also be performed using appropriate proportional clamps and direct injection of SealantCompound, whose reliable and reliable results have been proven.
• It should be noted that the use of this method (Box Clamp / Sealant Compound) is also applicable in many other cases, such as Reducer, T-Joints and other connections, which are referred to below as an example:
Construction and installation of clamps:
• Cutting and machining of sheets according to the construction plan and the size taken from the position.
• Supply and install the nipple and plug valve and Elbow with a size of 10mm and a grade # 3000 for holes mounted on the clamp for injection. (It needs to be explained that Elbow attempts to block the clamp hole for situations where the Gun can be changed and the plug for the situations where there is no access to the hole)
Clamp installation at leak site:
• Due to the fact that the clamp is two or more pieces, before installing the first half, the nipple and the corresponding valves must be installed on the existing holes of the clamp so that the valves that are located in the leakage side are open to allow the fluid to come out from the inside out. To be transferred.
• The first half of the clamp is in the place where the leakage is minimal.
• In the second half, the clamp must be carefully installed and the screws on the sides close quickly. At the time of work, it should be ensured that the sides are folded to the appropriate size.
• Install the injection gun on the opposite nipples of the leak and connect it to the jack and the components of the injection device.
• Place the compost in the injection gun and inject it into the Clamp. It is important to note that at the time of injection, the valves should be opened first and after each injection should be closed even if the injected component is not thrown out due to the pressure inside the Clamp.
• In the first injection, take some injection that, firstly, the leakage situation has been reduced to some extent, and the possibility of using a hydraulic jack is hardly possible.
• After this stage, the position of the gun is displaced and the place where the fluid is removed from the nipple clamp is installed and again the operation is repeated.
• Injection operation from the holes embedded in the same way until complete leakage is complete.
• After a few hours, the leak may reappear after a few hours, just refill a small amount of the component to clear the leak.
• Before closing the injection gun, clamp all the volcanoes.
Safety tips at runtime:
• Use the face shield to protect the fluid from leakage and prevent the possibility of throwing small pieces of compost out.
• Use resistant and suitable gloves.
• If leakage is of the hydrocarbon type, use a nitrogen or water parachute whenever it is used for drilling, milling or hammering.
• When placing the component inside the infusion gun, be sure to “take care of your fingers to prevent their injury.”
• When opening the hoses of the machine, make sure their oil is not pressurized.
• If leakage is in the vicinity of the oxygen line, make sure that the injection device is leaking and safe.
