Supply circumstances: EPT tubes are shipped in subsequent problems (first symbol lists prior designation, the new one according to EN is in brackets):
BK ( C) Chilly concluded/tough (cold completed as drawn).
No heat therapy right after previous chilly forming approach.
BKW ( LC) Cold completed/comfortable (flippantly chilly worked).
After final warmth therapy there is a mild ending move (cold drawing).
BKS ( SR) Cold finished/anxiety reduce annealed.
Right after the final chilly forming method the tubes are tension minimize annealed.
GBK ( A) Annealed.
Following the final chilly forming method the tubes are annealed in a managed environment.
NBK ( N) Normalized.
Soon after the final cold forming process the tubes are annealed earlier mentioned the higher transformation level in a controlled atmosphere.
Exams: all tubes are checked in accordance to the relevant creation stXiHu (West EPT) Dis.Hu (West EPT) Dis.rdsupplementary/optional assessments are offered on request chemical mechanical and technological exams are manufactured according to pertinent stXiHu (West EPT) Dis.Hu (West EPT) Dis.rd
Certificates: in accordance to EN 15714 3.1
