The stainless steel pipes and filters are manufactured with longitudinal weldings made in full penetration with the PLASMA (PAW) process, while the circular weldings are produced with an automatic MIG process with a minimum penetration of 90% of the thickness.
The welding procedures indicated have been drawn up and tested to minimize the deterioration of the alloy steels to avoid the formation of intergranular corrosion phenomena and keep the mechanical characteristics of the base material as unaltered as possible.
All welding processes, carbon steel and stainless steel, are done in compliance with the Welding Procedure Qualification Record WPQR performed by qualified personnel and certified by TUV Italia.
