Supply problems: EPT tubes are delivered in following problems (initial image lists previous designation, the new one according to EN is in brackets):
BK ( C) Chilly concluded/tough (cold concluded as drawn).
No warmth treatment method soon after very last chilly forming method.
BKW ( LC) Cold completed/gentle (flippantly cold labored).
After final warmth treatment there is a light finishing go (chilly drawing).
BKS ( SR) Chilly finished/stress reduce annealed.
Following the closing cold forming process the tubes are tension relieve annealed.
GBK ( A) Annealed.
After the final chilly forming method the tubes are annealed in a managed ambiance.
NBK ( N) Normalized.
Right after the last chilly forming method the tubes are annealed over the upper transformation point in a managed ambiance.
Assessments: all tubes are checked according to the relevant manufacturing stXiHu (West EPT) Dis.Hu (West EPT) Dis.rdsupplementary/optional tests are offered on request chemical mechanical and technological tests are created in accordance to related stXiHu (West EPT) Dis.Hu (West EPT) Dis.rd
Certificates: in accordance to EN 15714 3.one
