Supply circumstances: EPT tubes are shipped in pursuing situations (very first symbol lists preceding designation, the new 1 according to EN is in brackets):
BK ( C) Cold finished/difficult (chilly completed as drawn).
No warmth treatment after last chilly forming procedure.
BKW ( LC) Chilly completed/comfortable (lightly cold labored).
After last heat therapy there is a mild ending pass (cold drawing).
BKS ( SR) Cold completed/pressure alleviate annealed.
Right after the closing cold forming process the tubes are stress reduce annealed.
GBK ( A) Annealed.
Following the last cold forming process the tubes are annealed in a managed environment.
NBK ( N) Normalized.
Following the ultimate cold forming process the tubes are annealed previously mentioned the higher transformation level in a controlled environment.
Assessments: all tubes are checked according to the appropriate manufacturing stXiHu (West EPT) Dis.Hu (West EPT) Dis.rdsupplementary/optional tests are accessible on request chemical mechanical and technological checks are made according to pertinent stXiHu (West EPT) Dis.Hu (West EPT) Dis.rd
