Stainless steel hydraulic tubing

Hydraulic tubing and instrumentation tubing

Tube, pipe, fittings and flanges

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.

Hydraulic tubing and instrumentation tubing

Standard delivery form for hydraulic and instrumentation tube from Alleima 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

Our 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.

The tables show Alleima's standard grades for hydraulic and instrumentation tubing. Other grades can be offered on request.

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

Alleima 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
