Manufacturers and suppliers of 304 Stainless Steel Seamless Hydraulic Tubes & Instrumentation Tubes, engineered for fluid power systems, control lines, and precision instrumentation applications requiring excellent dimensional accuracy, and corrosive service environments.
Our 304 Stainless Steel Seamless Hydraulic Tubes & Instrumentation Tubes
are engineered for precision fluid power and control systems where dimensional
accuracy, clean internal surfaces, and consistent mechanical performance are critical.
Manufactured from premium AISI 304 / UNS S30400 stainless steel, these tubes offer
excellent resistance to oxidation, general corrosion, and scaling in a wide range
of industrial and commercial environments.
The seamless, high-precision construction ensures uniform wall thickness and a
smooth internal bore, reducing pressure loss 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 long-term operational reliability.
Widely used in oil & gas control systems, chemical processing plants, power
generation facilities, pharmaceutical and food & beverage equipment, and
industrial automation, our 304 stainless steel seamless tubes are manufactured
and tested to meet international standards, delivering a durable, hygienic,
and cost-effective solution for precision piping and pressure service needs.
Our 304 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 serve the UAE, Saudi Arabia, Qatar, Kuwait, Oman, Bahrain, Jordan, and Iraq, where our 304 stainless steel hydraulic and instrumentation tubes are relied upon for oil & gas control systems, water treatment plants, industrial piping networks, and precision fluid transfer 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 consistent performance in manufacturing, process automation, and industrial equipment 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 304 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.
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 instrumentation systems.
AISI 304 / UNS S30400 stainless steel provides strong resistance to general corrosion, oxidation, and scaling, making these tubes suitable for a wide range of industrial, commercial, and indoor/outdoor service environments.
Smooth internal surfaces minimize contamination, pressure drop, and flow turbulence, ensuring precise signal transmission and consistent performance in sensitive control, sensing, and measurement lines.
Designed to withstand moderate to high operating pressures and thermal variations, ensuring dependable service in hydraulic circuits, fluid power systems, and industrial piping networks.
Available in a broad range of diameters, wall thicknesses, and custom cut lengths, with optional bending, polishing, and surface finishes to meet project and OEM specifications.
Durable metallurgy and consistent quality help reduce downtime and lifecycle costs in chemical processing, power generation, automation, and precision fluid control applications.
304 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. This ensures a uniform austenitic microstructure, smooth internal surfaces, tight dimensional tolerances, and consistent mechanical properties required for precision fluid control, hydraulic systems, and instrumentation lines.
Each tube undergoes comprehensive quality checks including Eddy Current Testing (ECT), Hydrostatic or Pneumatic Pressure Testing, Positive Material Identification (PMI), chemical composition analysis, mechanical property testing, dimensional inspection, surface roughness verification (on request), and 100% visual inspection. These procedures ensure reliable performance in high-pressure, clean service, and precision control environments.
Manufactured in accordance with ASTM A269, ASTM A213, ASTM A511, and EN 10216-5 standards, and supplied under ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 quality systems. Tubes are delivered with EN 10204 3.1 / 3.2 Inspection Certificates, ensuring full traceability, regulatory compliance, and acceptance for EPC, OEM, and industrial automation projects worldwide.
