Vahterus is the biggest manufacturer of ASME compliant pressure equipment in Finland, both in terms of quantity and tonnage. This became apparent in the end of last year, after the ASME audit that is carried out every three years. The chief auditor was from the UK and the two other members of the team were from Finland.
We can now stamp our products with the ASME U and R symbols for another three years. Vahterus has had authorisation to stamp its products manufactured in Kalanti with the U symbol since 2004. Stamping repaired heat exchangers with the R symbol is been permitted since 2010. The American ASME system is widely used globally, for example in the United States, Canada, South America and South Korea.
