Delivery problems: EPT tubes are sent in following circumstances (1st symbol lists earlier designation, the new one particular according to EN is in brackets):
BK ( C) Cold completed/tough (chilly concluded as drawn).
No warmth treatment method soon after previous chilly forming method.
BKW ( LC) Chilly concluded/soft (evenly chilly worked).
After previous heat therapy there is a light finishing move (chilly drawing).
BKS ( SR) Chilly completed/tension alleviate annealed.
Right after the closing chilly forming method the tubes are tension minimize annealed.
GBK ( A) Annealed.
Following the final cold forming approach the tubes are annealed in a managed environment.
NBK ( N) Normalized.
Right after the closing cold forming procedure the tubes are annealed previously mentioned the higher transformation position in a managed ambiance.
Checks: all tubes are checked in accordance to the relevant production stXiHu (West EPT) Dis.Hu (West EPT) Dis.rdsupplementary/optional tests are obtainable on ask for chemical mechanical and technological exams are made in accordance to relevant stXiHu (West EPT) Dis.Hu (West EPT) Dis.rd
Certificates: in accordance to EN 15714 3.1
