Manufacturers and suppliers of 304LN Stainless Steel Seamless Hydraulic Tubes & Instrumentation Tubes, engineered for precision fluid control, high-pressure systems, and reliable performance in demanding industrial and process service environments.
Our 304LN Stainless Steel Seamless Hydraulic & Instrumentation Tubes
are engineered for high-precision fluid control and demanding high-pressure
service environments where superior corrosion resistance, enhanced mechanical
strength, and long-term operational reliability are essential.
304LN is a low-carbon, nitrogen-alloyed austenitic stainless steel grade that offers
improved yield strength and excellent resistance to intergranular corrosion and
stress corrosion cracking, particularly in chloride-bearing and chemically aggressive
environments. The addition of nitrogen enhances mechanical performance while
maintaining excellent ductility and formability for precision tubing applications.
The seamless, high-precision manufacturing process ensures uniform wall thickness,
tight dimensional tolerances, and a smooth internal surface, reducing pressure drop
and improving flow accuracy in sensitive instrumentation lines, hydraulic systems,
and high-pressure process piping. These tubes are widely used in oil & gas facilities,
chemical and petrochemical plants, power generation, OEM equipment, and industrial
automation systems where safety, consistency, and performance are critical.
Our 304LN Stainless Steel Seamless Hydraulic & Instrumentation Tubes are trusted across major industrial hubs in India and throughout the Middle East, including the UAE, Saudi Arabia, Qatar, Kuwait, Oman, and Bahrain, supporting oil & gas facilities, power generation projects, chemical processing plants, water treatment systems, and large-scale EPC and infrastructure developments.
In Europe, we supply Italy, Germany, Spain, the United Kingdom, France, Turkey, and Eastern European markets, where our 304LN precision tubes are valued for dimensional accuracy, enhanced mechanical strength, and reliable performance in high-pressure instrumentation, automation, and high-temperature process environments.
Across Africa, the Americas, and the Asia-Pacific region, our 304LN stainless steel seamless tubes support refineries, power plants, OEM manufacturing, marine systems, and industrial automation projects, delivering dependable performance in corrosive, high-pressure, and mission-critical service conditions.
Wherever you operate—Doha, Dubai, London, Houston, Singapore, or Sydney— Seminox Pipes & Tubes delivers premium-quality 304LN Stainless Steel Seamless Hydraulic & Instrumentation Tubes, manufactured and certified to international standards for durability, full material traceability, and long-term performance in critical process control and fluid handling applications.
Manufactured using hot finished and cold drawn seamless processes to achieve uniform wall thickness, tight dimensional tolerances, and smooth internal surfaces for accurate flow control and reliable performance in critical hydraulic and instrumentation systems.
The addition of nitrogen improves yield strength and structural stability without compromising ductility, allowing safe operation in high-pressure and vibration-prone service environments.
Low-carbon 304LN chemistry provides excellent resistance to general corrosion, intergranular attack, and stress corrosion cracking, particularly in chloride-bearing and chemically aggressive process conditions.
Smooth bore finish minimizes pressure drop and turbulence, improving signal stability and response accuracy in sensitive instrumentation, control lines, and precision fluid handling systems.
Maintains mechanical integrity and dimensional stability under elevated temperatures and fluctuating pressures, making it suitable for power generation, refineries, and high-temperature process piping systems.
Designed for extended operational life with reduced inspection and replacement requirements, delivering cost-effective performance in oil & gas facilities, chemical plants, OEM manufacturing, and industrial automation applications.
304LN Stainless Steel Seamless Hydraulic & Instrumentation Tubes are manufactured using precision cold drawing and hot finishing processes, followed by controlled solution annealing and pickling or bright annealing. The nitrogen-alloyed, low-carbon austenitic structure ensures enhanced mechanical strength, excellent resistance to general and chloride-induced corrosion, and superior dimensional accuracy for critical hydraulic, pneumatic, and high-pressure fluid transfer applications.
Each 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, and 100% visual inspection. These measures ensure full compliance with ASTM A213, ASTM A269, EN 10216-5, and ASME SA213 standards for safety, reliability, and long-term performance in demanding instrumentation and hydraulic systems.
Manufactured in accordance with ASTM A213 / A269 / A632, ASME SA213 / SA269, EN 10216-5, ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and PED 2014/68/EU directives. Tubes are supplied with EN 10204 3.1 / 3.2 Mill Test Certificates (MTC), ensuring full material traceability, regulatory compliance, and acceptance for EPC, oil & gas, power generation, automation, and high-integrity instrumentation projects worldwide.
