Applications

Leakage test on gas pipes (leak and load test)

The technical regulation for gas installations (in short: TRGI) is a binding and at the same time important regulation for skilled trade. The TRGI governs how gas installations are to be planned, designed, serviced and maintained. This applies to all gas installations. This regulation is taken care of by the German Association for Gas and Water (DVGW). The TRGI 2008 is the current version. Amongst other things, this states that gas pipes are to be tested according to the construction phase (basic shell, completion, and repairs). The following inspections particularly play a role in the application stated here:

Load testing
During testing, the material is tested for stability and the connections for service life; this takes place prior to plastering over or concealment of the gas pipes. During load testing, the newly installed pipe, without fittings or gas appliances, is put under 1 bar pressure. The testing medium is air or inert gas. There must not be a drop in pressure during the test, which lasts at least 10 minutes.

Leak test
This test is for checking the pipe for leaks, without fittings and gas appliances. The measuring instrument must not register a drop in pressure during the minimum 10 minute testing period (depending on the system volume); the test pressure is 150 mbar (previously 110 mbar).

Leakage test on gas pipes in the boiler room

A gas installation set up according to the legal provisions of the German Association for Gas and Water (“DVGW”) and the TRGI 2008 is the prerequisite for proper, long-term operation. However, while in operation, operating conditions or other general conditions may affect the safety of the gas installation. Technical systems are subjected to wear and contamination in their daily use. Only an expert can identify, assess and repair these kinds of safety-related changes. The leak test (or more aptly, serviceability test, also known as leakage measurement) for the pipeline system is to be repeated every 12 years using a measuring instrument and recorded in a test results report. The operator thus has a technical expert report. Some buildings insurers include these inspections and certificates/reports in their general insurance terms. For the serviceability test or leakage measurement, the gas pipe is always tested in operating conditions/with operating pressure (no increased test pressure). During this test, a measuring instrument detects whether gas is leaking from the pipe and how much.

Measuring pressure on burners (nozzle pressure, gas flow pressure, etc.)

Standard readings taken during services of domestic heating systems include checking the gas pressure on the burners. This involves measuring the gas flow pressure and gas resting pressure. The flow pressure, also called supplied pressure, refers to the gas pressure of the flowing gas and resting pressure of the static gas. If the flow pressure for gas boilers is slightly outside the 18 to 25 mbar range, adjustments must not be made and the boiler must not be put into operation. If put into operation nonetheless, the burner will not be able to function properly, and explosions will occur when setting the flame and ultimately malfunctions; the burner will therefore fail and the heating system will shut down.

Measuring temperatures on radiators

When measuring temperatures on radiators, the flow and return temperature are recorded in particular and assessed by the tradesman. The flow temperature is defined as the temperature of the thermal transfer medium (e.g. water) that the system is supplied with. The temperature of the medium flowing out of the system is accordingly called the return temperature. To prevent losses within the heat distribution system and achieve a better level of efficiency spot recording of flow and return temperatures are necessary. Implementation of relevant measures ultimately leads to hydraulic adjustment on the basis of knowledge about the flow and return temperatures. This defines a procedure with which every radiator or heating circuit of a flat radiator within a heating system is supplied at a set flow temperature with the precise amount of heat needed to achieve the ambient temperature required for the individual rooms. Flawed operating conditions will result in considerable excess consumption of electricity and heating energy. The German Energy Saving Regulation (EnEV) therefore requires hydraulic adjustment for systems being set up or overhauled for this very reason.

Pressure tests on water pipes (drinking and waste water)

According to the legal regulations of DIN EN 806-4, DIN 1988-7 and DIN 1610, drinking and waste water pipes are to be tested for leaks before being put into service by means of a pressure test with air, inert gas, or water; they are also to undergo load testing with air or inert gas. However, for reasons of hygiene, it is best if the pipes remain dry until shortly before commissioning and do not undergo a leak test using water. A pressure test with air is also recommended to prevent metallic materials from corroding. The pressure test is split into two pressure-related parts where test pressure and time depend on the target (load or leak-proof). Leaks can usually be heard very quickly. If it is difficult to locate the leaks, the usual auxiliary tools and materials for gas pipes are used (spraying or painting on foaming solutions).
