Leakproofness tests. Role and importance
The tightness of welded joints is a very important issue from the point of view of functionality and safety of using various elements. Due to the great technical complexity of such an enterprise, various methods and techniques of control and research have been developed. The analysis results make it possible to detect possible leaks in advance, i.e. material irregularities throughout the checked object. Which leak testing method works best?Leak Control Characteristics
Leakproofness tests of pipes and other materials are carried out more and more frequently and are carried out by professional companies. On the other hand, it is a big mistake that such observations are carried out after the completion of work, when it is impossible to make constructive adjustments and so on.Also, the design does not always take into account the requirements related to the tightness class of the installation. Designers mistakenly assume that pipes are always sealed. However, this property is of particular importance in terms of installation efficiency and heat loss. The hermetic installation helps to increase the comfort and safety of users. This is exactly what specialized tests are conducted for.In the course of research activities, a leak detector and negative pressure are used. Small fluctuations in the pressure level along with negative pressure make it possible to detect any inhomogeneities in the material. Such tests are carried out on all those tanks, assemblies and pipelines that must have perfect tightness. Only the appropriate tightness class allows the use of this object.Bubble-vacuum method - is it worth it?
Currently, the most recommended method of leakproofness testing is bubbling. It is implemented by well-known technical laboratories. Using this technique reduces testing time as much as possible, so it can be implemented without disrupting other production operations. It is used, among other things, to check the tightness of installations (for liquid or gaseous media) and tanks.There are many different suction cups, so it is easy to test different types of welds. The vesicle-vacuum method has many advantages, the most important of which are:easy to implement,
low access requirements (only one weld surface is tested),
clean operation,
immediate leak indication directly on the specified surface.
Monitoring using this technique works especially in cases where RT diagnosis of welds is impossible, and ultrasound is too expensive for the enterprise. What does a leak test look like?
During the tests, a special vacuum chamber in the form of a suction cup is used, equipped with rubber gaskets. The selected joint area is smeared with a foaming solution. Then a chamber is placed above this section, inside of which a low negative pressure is created.If there is indeed a leak in the joint being examined, air passes through it into the chamber. A sign of this phenomenon is the soap bubbles appearing on its surface. 1Win offers new customers an industry-leading 500% welcome bonus up to €1,025 spread across their first four deposits.
