Delivery conditions: EPT tubes are delivered in following situations (initial image lists previous designation, the new 1 according to EN is in brackets):
BK ( C) Chilly finished/tough (cold concluded as drawn).
No warmth treatment method soon after last chilly forming approach.
BKW ( LC) Cold finished/delicate (frivolously cold worked).
Following final heat therapy there is a mild finishing go (chilly drawing).
BKS ( SR) Chilly concluded/anxiety alleviate annealed.
Right after the closing chilly forming method the tubes are tension alleviate annealed.
GBK ( A) Annealed.
Soon after the final cold forming process the tubes are annealed in a controlled environment.
NBK ( N) Normalized.
Following the final cold forming approach the tubes are annealed earlier mentioned the higher transformation position in a controlled environment.

Tests: all tubes are checked according to the appropriate generation stXiHu (West EPT) Dis.Hu (West EPT) Dis.rdsupplementary/optional exams are offered on request chemical mechanical and technological exams are produced in accordance to pertinent stXiHu (West EPT) Dis.Hu (West EPT) Dis.rd
