PAPER AND PULP MILLS
Refinec is experienced manufacturer for paper and pulp mill industries. We consider the demands of processes and optimize solutions based on those. We do not always search for the most economical option, our first goal is to offer high quality, safe and durable products to our clients.
Pulp mill special process conditions requires and demands that manufacturing materials are picked up invidually, based on the special needs of each device. In heat exchangers in pulp mills there can be matters which are very dirty, have special viscocity, are corrosive and consistency may vary. Besides these temperatures and pressure can be high, so all heat exchanger features are very important – also other than just thermo dynamics.
Few examples for materials we use with high skills:
– different carbon steels
– different stainless steels
– Creep Resisting Steels
– duplex-steel
– super austenitic stainless steels (6Mo)
– titanium
– aluminium
– copper alloys
– nickel alloys (for example Alloy 825, Alloy 625, Monel 400)
– compound-materials
Besides the correct material also welding method is important to ensure the highest quality.
In production we invest all the time to the latest manufacturing methods to guarantee the highest possible manufacturing quality. As an example of this we can mention our new orbital welding station and Finland’s first hybrid welding station.
Refinec delivers all kinds of products, for example:
– tube heat exchangers
– coolers
– heat exchangers
– pre-heaters
– feed water and other tanks
– reactors
– colums
– dryers
– demisters
– steam batteries
Refinec uses approved welding methods for various materials and process demands. In planning we use vibration analysis for mathematic modeling and FEM method (Finite Elemet Method)for strenght calculation.
Our delivery projects are carefully documented and we keep especially our focus in keeping dead lines and clients informed.
