Shipping and delivery conditions: EPT tubes are sent in pursuing circumstances (initial symbol lists earlier designation, the new one according to EN is in brackets):
BK ( C) Chilly finished/difficult (cold completed as drawn).
No heat treatment method right after last chilly forming method.
BKW ( LC) Cold completed/comfortable (frivolously chilly labored).
Soon after last heat remedy there is a light finishing go (chilly drawing).
BKS ( SR) Cold concluded/tension alleviate annealed.
After the final cold forming process the tubes are tension relieve annealed.
GBK ( A) Annealed.
Right after the ultimate cold forming approach the tubes are annealed in a managed environment.
NBK ( N) Normalized.
After the final cold forming process the tubes are annealed previously mentioned the upper transformation stage in a managed atmosphere.
