Installation of district heating pipes and natural gas pipelines often require pipe installation work inside buildings. KVL-Tekniikka holds all the permits, method tests and welding instructions required for internal installations, including for PED category pipelines.
KVL-Tekniikka has the ISO 3834-2 certification of welding quality management.
On the basis of method tests, we have also drawn up pWPS welding instructions for the use of our employees. According to the welding instructions, every installation inside a property is implemented in an appropriate and sustainable way with a high level of quality.
