Hydraulic 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) 3 to 50 mm (0.118 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.) can be delivered with plugged ends for transport protection against inside contamination.
Materials and standards
The tables show Sandvik's standard grades for hydraulic and instrumentation tubing. Other grades can be offered on request.

1) Either flattening or ring expanding test
2) Hydrostatic test is replaced by Eddy Current 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 (DIN 50914)
5) Sandvik performs ASTM A262 PrE
5a) Sandvik also performs ASTM A262 PrE
6) Sandvik performs hardness test
7) Also according to DIN 17458 TC1
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
Tubes with outside diameter (OD) up to and including 30 mm (1.18 in.) are supplied bright annealed. Tubes with OD larger than 30 mm are supplied in the annealed and pickled condition. For information about maximum working pressure for each size and grade, use our pressure calculation tool.
