SSID / DOM Cold Drawn Welded Tube Honed Tube For The Hydraulic / Pneumatic Cylinder
SSID/DOM TUBE
Detailed Product Description
With the aid of a special drawing technique, the cold drawn welded tube with a inside smooth and
compressed surface can directly used for the hydraulic and pneumatic cylinder application ( ready-to-use). The hoing or burnishing is not required. Compared to the seamless tube, the advantage of
the SSID reduce the wall thickness deviation and the material cost.
Specification:
EN10305-2 , DIN 2393, ASTM A513 Type 6
ID tolerance: H9
ID roughness: Ra ≤ 0.80u
Concentricity < 3%
Delivery status: BK or BKS
Honing or Burnishing process can be provided after SR on SSID tubes with H8 tolerance.
The welded tubes were approved by eddy current testing and ultrasonic testing.
Hydraulic cylinders were also approved by eddy current test.
Finished tubes are also tested by UT and ET,
Ultrasonic Test (EN10246-7),Eddy current test(EN 10246-3)
