Delivery conditions: EPT tubes are sent in pursuing problems (very first image lists preceding designation, the new one particular according to EN is in brackets):
BK ( C) Cold concluded/hard (chilly concluded as drawn).
No heat therapy after very last chilly forming method.
BKW ( LC) Cold completed/delicate (frivolously chilly worked).
Soon after very last warmth treatment there is a gentle ending go (chilly drawing).
BKS ( SR) Cold finished/anxiety alleviate annealed.
Following the closing chilly forming approach the tubes are stress alleviate annealed.
GBK ( A) Annealed.
After the last cold forming process the tubes are annealed in a managed environment.
NBK ( N) Normalized.
Right after the last cold forming approach the tubes are annealed previously mentioned the higher transformation level in a controlled ambiance.
Exams: all tubes are checked according to the pertinent manufacturing stXiHu (West EPT) Dis.Hu (West EPT) Dis.rdsupplementary/optional checks are available on ask for chemical mechanical and technological checks are manufactured according to related stXiHu (West EPT) Dis.Hu (West EPT) Dis.rd
Certificates: in accordance to EN 15714 three.1
