Hydraulic & Instrumentation Tubing

Alleima offers an extensive range of seamless Hydraulic & Instrumentation (H&I) tubing engineered to provide high system integrity in critical fluid and pressure-control applications.

Available in corrosion-resistant austenitic stainless steels, duplex and super-duplex stainless steels, high-alloy materials and nickel alloys, Alleima H&I tubing combines smooth surfaces with close dimensional tolerances to support secure tube connections and reduce the risk of leakage. The range is available in straight lengths as well as coils for suitable applications.

Typical applications include:

Instrumentation Lines | Hydraulic Systems | Process Control | Chemical Injection | Gas Systems | Utility Systems | Offshore Installations | Analytical & Process Measurement

Advanced Materials for Demanding Environments

Different applications demand different levels of corrosion resistance, mechanical strength and environmental performance. Alleima's extensive materials portfolio enables customers to select tubing according to the specific operating conditions of the system.

Key materials available across the H&I and tube portfolio include:

• 304 / 304L – for general-purpose tubing requirements.

• Alleima® 3R65 / 316L – proven 316L stainless steel for instrumentation and hydraulic applications.

• Alleima® 3R60 – higher-alloyed 316L with controlled chemistry for enhanced corrosion performance.

• SAF™ 2205 – duplex stainless steel combining corrosion resistance with high mechanical strength.

• SAF™ 2507 – super-duplex stainless steel for highly corrosive and demanding offshore environments.

• Alleima® 254 SMO – high-alloy austenitic stainless steel developed for seawater and aggressive chloride-bearing environments.

• Sanicro® 41 / Alloy 825 – nickel alloy suited to sour, acidic and chloride-containing environments.

• Sanicro® 35 – advanced high-performance alloy combining excellent corrosion resistance with high strength for severe environments.

High-Pressure Tubing

For applications operating under extreme pressure, Alleima provides seamless high-pressure tubing engineered to combine high yield and tensile strength, corrosion resistance and good elongation characteristics.

Applications include:

High-Pressure Hydraulic Systems | Test Benches | Waterjet Equipment | Chemical Processing | Gas Systems | Industrial Pressure Systems

Applicable high-pressure tubing can also undergo autofrettage treatment to improve fatigue life and pressure-cycle durability.

Coiled Tubing & Long-Length Solutions

Alleima has extensive experience in the production of stainless steel tubing in coils and on spools, including long-length precision tubing.

Long continuous lengths can help minimise the number of connections and welds required during installation, supporting reduced installation time and improved system integrity.

Alleima's coiled tube capabilities extend across:

Hydraulic & Instrumentation Tubing | Chemical Injection Lines | Control Lines | Umbilical Tubing
