Manufacturers and suppliers of 304L Stainless Steel Seamless Hydraulic Tubes & Instrumentation Tubes, engineered for precision fluid power, control lines, and sensitive instrumentation systems requiring excellent dimensional accuracy, high-pressure, and hygienic service environments.
Our 304L Stainless Steel Seamless Hydraulic Tubes & Instrumentation Tubes
are engineered for precision fluid power and control systems where superior
corrosion resistance, dimensional accuracy, and long-term reliability are essential.
Manufactured from low-carbon AISI 304L / UNS S30403 stainless steel, these tubes
offer excellent resistance to oxidation, general corrosion, and intergranular
attack, particularly in welded and high-hygiene service environments.
The seamless, high-precision construction ensures uniform wall thickness and a
smooth internal bore, reducing pressure drop and improving system responsiveness
in hydraulic circuits, pneumatic lines, and sensitive instrumentation applications.
These tubes maintain structural integrity under varying pressures and temperature
conditions, ensuring consistent, leak-free performance.
Widely used in oil & gas control systems, chemical and petrochemical plants, power
generation facilities, pharmaceutical and food & beverage equipment, and industrial
automation, our 304L stainless steel seamless tubes are manufactured and tested to
meet international standards, delivering a durable, hygienic, and cost-effective
solution for precision piping and fluid handling needs.
Our 304L Stainless Steel Seamless Hydraulic Tubes & Instrumentation Tubes are trusted across major industrial cities in India, including Mumbai, Chennai, Pune, Ahmedabad, and Hyderabad, supporting chemical processing, automation, fluid handling, power generation, and large-scale infrastructure and EPC projects.
In the Middle East, we supply the UAE, Saudi Arabia, Qatar, Kuwait, Oman, Bahrain, Jordan, Iraq, and Lebanon, where our 304L stainless steel tubes are relied upon for oil & gas control systems, water treatment facilities, industrial piping networks, and precision instrumentation in demanding service environments.
Across Europe—including Germany, Italy, France, Spain, the United Kingdom, Turkey, and Eastern European markets—our tubes are valued for their dimensional accuracy and corrosion resistance in manufacturing, pharmaceutical, food processing, and industrial automation systems. In Africa, the Americas, and the Asia-Pacific region, our products support marine, chemical processing, power generation, mining, and large-scale industrial projects operating in corrosive and high-pressure environments.
Wherever you operate—Doha, Dubai, London, Moscow, or New York—Seminox Pipes & Tubes delivers premium-quality 304L Stainless Steel Seamless Hydraulic Tubes & Instrumentation Tubes, manufactured and certified to international standards for traceability, durability, and long-term performance in precision piping and pressure service applications worldwide.
AISI 304L / UNS S30403 stainless steel offers enhanced resistance to intergranular corrosion, making these tubes ideal for welded hydraulic and instrumentation systems in corrosive and hygienic service environments.
Cold drawn and hot finished seamless processes ensure uniform wall thickness, tight dimensional tolerances, and a clean, smooth internal bore for reliable performance in hydraulic, pneumatic, and precision control lines.
Provides strong resistance to general corrosion, oxidation, and scaling, enabling long-term service in chemical processing, pharmaceutical, food-grade, and industrial automation environments.
Smooth internal surfaces reduce contamination, pressure drop, and flow turbulence, ensuring precise signal transmission and consistent performance in sensitive measurement and control applications.
Designed to withstand moderate to high operating pressures and thermal cycling, providing dependable performance in hydraulic circuits, pneumatic systems, and industrial fluid handling networks.
Available in a broad range of diameters, wall thicknesses, and custom cut lengths, with optional polishing, bending, and special surface finishes to meet EPC, OEM, and project-specific requirements.
304L Stainless Steel Seamless Hydraulic and Instrumentation Tubes are produced using precision cold drawing and hot finishing processes, followed by solution annealing and pickling or bright annealing. The low-carbon austenitic microstructure ensures excellent weldability, resistance to intergranular corrosion, smooth internal surfaces, and tight dimensional tolerances required for clean service, hydraulic, and precision control systems.
Every tube undergoes comprehensive quality control procedures including Eddy Current Testing (ECT), Hydrostatic or Pneumatic Pressure Testing, Positive Material Identification (PMI), chemical composition analysis, mechanical property testing, dimensional verification, surface condition checks, and 100% visual inspection. These measures ensure reliable performance in high-pressure, hygienic, and precision instrumentation environments.
Manufactured in accordance with ASTM A269, ASTM A213, ASTM A511, and EN 10216-5 standards under ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 quality systems. Tubes are supplied with EN 10204 3.1 / 3.2 Inspection Certificates, ensuring full material traceability, regulatory compliance, and acceptance for EPC, OEM, pharmaceutical, food processing, and industrial automation projects worldwide.
