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)

11. Tube Ends
Tube ends shall cut square to the tube axis and be free from excessive burrs.
Both ends protected with Plastic caps.

As the result of stress relieved annealing after the final drawing, residual stresses are reduced, forming within defined limits is made possible, and dimensional changes during/after machining are minimized.
