German olefin producer had a major shut-down at their ethylene cracker in September 2012 and some valves were sent for service to Metso Automation’s service center in Horgau, Germany. This was already the second time that this customer sent their valves for service to our valve factory. Are these valves not working well? Let’s see what our German colleague Raimar Hellwig, Business Manager of Mapag® butterfly valves has to say about this:
Raimar: “Actually the valves are working very well and they do this already for more than 10 years. To mention one example: despite the very challenging fluid of cracked hydrocarbons, all the ethylene cracker valves which are installed until today provide very safe and reliable operation without any known case of jamming during opening or closing. This service was part of the scheduled shut-down for the ethylene cracker that takes place every 6 years. This is the typical frequency that these kind of valves should be maintained and spare parts can be changed.
