Hydraulic tubing and instrumentation tubing

Hydraulic tubes and instrumentation tubes in a comprehensive range of corrosion-resistant stainless steels and nickel alloys covering outside diameters from (OD) 1.59 to 50 mm (0.0625 to 1.968 in.). All sizes are supplied with smooth surfaces and close dimensional tolerances reducing the risk of leakages when connecting tubes with couplings.

Standard delivery form for Sandvik hydraulic and instrumentation tube is straight lengths of 6 meters, but our tubes can also be delivered as coiled tubing, contributing to reduced installation costs.

Tubes with high cleanliness

Sandvik hydraulic tubes and instrumentation tubes are characterized by high cleanliness, and tubes with OD larger than 5 mm (0.196 in.) are delivered with plugged ends for transport protection against inside contamination.

1) Either flaring or flattening test depending on tube size.
2) Eddy Current or hydrostatic test at option of Sandvik.
3) Also product analysis of a billet or tube from each heat.
4) Sandvik performs EN ISO 3651-2 Method A.
5) Sandvik performs ASTM A262 PrE.
6) Sandvik performs hardness test.

Coiled tubing

Coiled tubing

Sandvik stainless hydraulic tubes and instrumentation tubes can also be delivered in coils, contributing to reduced installation cost due to:

  • Fewer connections
  • Higher degree of materials utilization
  • Improved system integrity
