Dimensions of the galvanized tubes for hydraulic and pneumatic lines
 
Outside diameter ranges from 6 to 350 mm and the wall thickness ranges from 0.8 to 30 mm.
Precision steel tubes are delivered according to EN 10305-4, DIN 2391-1, STN 42 6711 and 42 6712, ČSN 42 6711 and 42 6712.
 
Synopsis of Process Routing
DIN highly accurate cold drawn bright seamless steel tube is used as the tube to be galvanized, the outer wall is electroplated, caps are covered at two ends of tube to prevent from the dust.
Main Features
Different color of zinc such as white, yellow, army-green, black is evenly distributed in the surface of the tube, good brightness and antirust and antisepsis could improve after zinc coated.
 
Length of the galvanized tubes
in diameter <= 16 mm  >=6000 + 100 mm
in diameter >= 16 mm  <=24000 + 50 mm
 
Tolerances of the zinc coated tubes
 
- tolerances of the outside diameter:

diameter between 4 - 30 mm

±0,08 mm

diameter between 35 - 38 mm

±0,15 mm

diameter above 42 mm

±0,20 mm

 
  • tolerances of the inside diameter are according to EN 10305-4

Final supply conditions
 

Designation

Symbol

Description

Cold finished (hard)

BK

Tubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation.

Cold finished (soft)

BKW

The final heat treatment is followed by cold drawing involving limited deformation. Appropriate further processing allows a certain degree of cold forming (e.g. bending, expanding).

Cold finished and stress-relieved

BKS

Heat treatment is applied following the last cold forming process. Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degree.

Annealed

GBK

The last cold forming process is followed by annealing in a controlled atmosphere.

Normalized

NBK

The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.

Applications
 
Zinc coated precision steel tubes (galvanized tubes) are destined for hydraulic and pneumatic pressure distribution (so called HPL tubes), production of automobile components, utility vehicles as well as for production of machine products such as fittings and joints. Cold drawn precision tubes are used as the semi-finished product and they are made from rolled seamless tubes. Precision tubes HPL types are made from carbon and alloyed steel.
