Delivery problems: EPT tubes are delivered in subsequent conditions (very first image lists prior designation, the new one according to EN is in brackets):
BK ( C) Cold finished/hard (chilly concluded as drawn).
No warmth treatment after last cold forming procedure.
BKW ( LC) Chilly concluded/delicate (frivolously cold labored).
Following previous heat therapy there is a light finishing go (cold drawing).
BKS ( SR) Cold concluded/stress relieve annealed.
Right after the last chilly forming approach the tubes are pressure alleviate annealed.
GBK ( A) Annealed.
Right after the final chilly forming method the tubes are annealed in a managed environment.
NBK ( N) Normalized.
Soon after the last cold forming process the tubes are annealed earlier mentioned the higher transformation point in a controlled ambiance.
Assessments: all tubes are checked according to the pertinent production stXiHu (West EPT) Dis.Hu (West EPT) Dis.rdsupplementary/optional checks are available on request chemical mechanical and technological tests are produced according to appropriate stXiHu (West EPT) Dis.Hu (West EPT) Dis.rd
Certificates: in accordance to EN 15714 3.1
