With excellent formability, high surface quality, and reliable resistance to oxidation and chemical attack, these tubes deliver consistent flow control, system safety, and extended service life in critical hydraulic and instrumentation applications.
Our 1.4306 Stainless Steel Seamless Hydraulic & Instrumentation Tubes,
also known as AISI 304L, are engineered for precision fluid and gas
control systems where corrosion resistance, cleanliness, and long-term reliability
are essential. The low-carbon composition of EN 1.4306 (X2CrNi19-11)
significantly reduces the risk of intergranular corrosion, particularly in welded
and heat-affected zones, ensuring superior structural integrity in critical
instrumentation and hydraulic applications.
The seamless, cold-finished construction provides uniform wall thickness and
exceptionally smooth internal surfaces, minimizing pressure loss and promoting
consistent, contamination-free flow. These properties make the tubes ideal for
high-purity and high-precision environments where system accuracy, safety, and
performance must be maintained under continuous operation.
Widely used in chemical processing, pharmaceutical and food & beverage industries,
oil & gas systems, and industrial automation, our 1.4306 stainless steel seamless
tubes offer excellent formability, weldability, and resistance to oxidation and
mild chemical attack. Manufactured and tested to international standards, they
provide a durable, hygienic, and cost-effective solution for corrosion-sensitive
and precision-driven service environments.

Across Africa, the Americas, and the Asia-Pacific region—including the United States, Canada, Brazil, Mexico, South Africa, Nigeria, Singapore, Malaysia, Thailand, Vietnam, and Australia—our 1.4306 Stainless Steel Seamless Hydraulic & Instrumentation Tubes are trusted in chemical processing, food and pharmaceutical manufacturing, power generation, offshore operations, and industrial automation systems.
Wherever you operate—Doha, Dubai, London, Houston, Singapore, or Sydney—Seminox Pipes & Tubes delivers premium-quality 1.4306 Stainless Steel Seamless Hydraulic & Instrumentation Tubes (AISI 304L), manufactured and certified to international standards to ensure full traceability, consistent surface quality, and long-term performance in critical fluid control and precision instrumentation applications worldwide.
Produced using advanced cold drawing and seamless forming processes to achieve uniform wall thickness, tight dimensional tolerances, and smooth internal surfaces for reliable fluid transfer and precise instrumentation performance.
The low-carbon chemistry of 1.4306 / AISI 304L minimizes the risk of intergranular corrosion in welded and heat-affected zones, ensuring strong, durable joints and long-term structural stability in hydraulic and instrumentation systems.
Provides reliable resistance to oxidation, moisture, and mild chemical attack, making these tubes suitable for chemical processing, food & beverage, pharmaceutical, and industrial service environments.
Precision-finished internal surfaces reduce friction, minimize pressure drop, and promote stable, contamination-free flow in sensitive measurement and control systems.
Excellent ductility and workability allow for easy bending, flaring, and welding, enabling efficient fabrication and installation across complex hydraulic and instrumentation layouts.
Engineered for extended durability, reduced downtime, and lower lifecycle costs in precision manufacturing, process industries, and clean-service applications requiring dependable, corrosion-resistant tubing.
1.4306 Stainless Steel Seamless Hydraulic & Instrumentation Tubes are manufactured using precision cold drawing and cold rolling processes, followed by controlled solution annealing and pickling or bright annealing. This produces a fully austenitic, homogeneous microstructure with excellent surface quality, reliable corrosion resistance, and tight dimensional tolerances for clean-service, hygienic, and precision fluid control applications.
Each tube undergoes comprehensive quality control including Eddy Current Testing (ECT), Hydrostatic or Pneumatic Pressure Testing, Positive Material Identification (PMI), chemical composition verification, mechanical testing, dimensional inspection, and 100% visual examination. These procedures ensure full compliance with ASTM A213 / A269 and ASME SA213 / SA269 standards for safe and reliable performance in corrosion-sensitive and precision instrumentation environments.
Manufactured in accordance with ASTM A213, ASTM A269, ASME SA213, ASME SA269, EN 10216-5, DIN EN 10088-2, 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 traceability, regulatory compliance, and acceptance for EPC, pharmaceutical, food processing, chemical, oil & gas utility, and industrial automation projects worldwide.
