Precision seamless galvanized steel tube
Pipes are used in hydraulic cystems, like automotive shock absorbers, Hydraulic circuits, pneumatic lines or hand flares etc.
Applications:
* automotive shock absorbers
* Hydraulic pillar
* pneumatic lines
* automotive steering shaft

Standard:
DIN 2391, EN10305-1, EN 10305-4, DIN 1630, DIN 2445
St30al, st37.4, st 37, st45, st52, st52.3, 37Mn5 etc.

Size:
OD from 4mm to 127mm
WT from 0.7 to 10mm

Advantage:
The pipes enjoy high wear-resistance and concentricity, The inner and outer surface is smooth like a mirror. These tubes can be bent at any angle and bear the impact of high pressure, cold bending, flaring, flatting, and tensile force without cracks and breaks, without oxidized residual substances on either inner or outer surface of tubes. Additionally, blockage to pneumatic, hydraulic and oil routes shall never occur. The elongation rate and tensile strength are in high standard.

Process way:
Precision cold rolled or precision cold drawn

Delivery condition:
BK, NBK(Bright)

Additional Processing:
Oiling, cleaning, cutting, beveling

Surface:
Silver galvanized, yellow galvanized, blue-white galvanized, olive green galvanized
