Manufacturers and suppliers of 316H Stainless Steel Seamless Hydraulic & Instrumentation Tubes, designed for high-temperature and high-pressure service in oil & gas, petrochemical, power generation, and process industries.
Our 316H Stainless Steel Seamless Hydraulic & Instrumentation Tubes
are engineered for high-temperature and high-pressure industrial environments
where elevated mechanical strength, thermal stability, and long-term
operational reliability are critical. The high-carbon
316H grade delivers improved creep resistance and enhanced
tensile strength at elevated temperatures, making these tubes ideal for
demanding service in petrochemical, power generation, and process industries.
The seamless, high-precision construction ensures uniform wall thickness and
smooth internal surfaces, minimizing pressure losses and maintaining consistent
flow performance in critical hydraulic and instrumentation systems. These tubes
perform reliably under sustained heat exposure, thermal cycling, and extreme
operating pressures.
Commonly used in oil & gas processing units, refineries, chemical and
petrochemical plants, offshore platforms, power generation facilities, and
high-temperature control and instrumentation networks, our 316H stainless
steel seamless tubes are manufactured and tested to international standards
to provide a durable, heat-resistant, and cost-effective solution for
harsh and high-temperature operating environments.
Our 316H Stainless Steel Seamless Hydraulic & Instrumentation Tubes are trusted across major industrial cities in India and throughout the Middle East, including the UAE, Saudi Arabia, Qatar, Kuwait, Oman, Bahrain, Iraq, and Jordan. These regions rely on our high-carbon, heat-resistant tubing solutions for oil & gas operations, refineries, petrochemical plants, power generation units, and large-scale infrastructure and EPC projects that demand reliable performance in high-temperature and high-pressure service environments.
In Europe, we supply Italy, Germany, Spain, the United Kingdom, France, Turkey, Greece, and Eastern European markets, where our 316H stainless steel seamless tubes are valued for their elevated-temperature strength, dimensional precision, and consistent performance in demanding hydraulic, marine, and high-temperature instrumentation applications.
Across Africa, the Americas, and the Asia-Pacific region, our 316H Stainless Steel Seamless Hydraulic & Instrumentation Tubes support offshore platforms, marine systems, chemical and petrochemical plants, power generation facilities, and heavy manufacturing industries—delivering dependable performance in corrosive, high-pressure, and high-temperature operating conditions.
Wherever you operate—Doha, Dubai, London, Moscow, or New York—Seminox Pipes & Tubes delivers premium-quality 316H Stainless Steel Seamless Hydraulic & Instrumentation Tubes, manufactured and certified to international standards for precision, traceability, and long-term performance in critical fluid control, heat-resistant, and instrumentation applications worldwide.
Produced using advanced cold drawing and seamless forming processes to ensure uniform wall thickness, tight dimensional tolerances, and smooth internal surfaces for consistent fluid flow and accurate instrumentation performance.
The high-carbon 316H grade provides improved creep resistance and mechanical strength at elevated temperatures, making these tubes ideal for high-heat service in petrochemical, refinery, and power generation applications.
Designed to withstand high internal pressures and mechanical loads, maintaining structural integrity in critical hydraulic systems, control lines, and precision fluid transfer networks.
Precision-finished internal surfaces reduce friction and pressure loss, enhancing flow stability and measurement accuracy in sensitive instrumentation and process control systems.
Maintains corrosion resistance and structural performance under high temperatures, cyclic pressure, and aggressive chemical and oxidizing service conditions.
Engineered for long-term durability, minimized downtime, and lower lifecycle costs in oil & gas processing, marine systems, chemical plants, and high-temperature industrial environments.
316H Stainless Steel Seamless Hydraulic & Instrumentation Tubes are produced using precision cold drawing and cold rolling processes, followed by controlled solution annealing and pickling or bright annealing. The high-carbon composition promotes a fully austenitic, homogeneous microstructure with enhanced high-temperature strength, improved creep resistance, and excellent surface finish, ensuring tight dimensional tolerances for high-pressure and elevated-temperature hydraulic and instrumentation service applications.
Each tube undergoes rigorous quality control including Eddy Current Testing (ECT), Hydrostatic or Pneumatic Pressure Testing, Positive Material Identification (PMI), chemical composition verification, mechanical and elevated-temperature property testing, dimensional inspection, and 100% visual examination. These procedures ensure compliance with ASTM A213 / A269 and ASME SA213 / SA269 standards for safe and reliable performance in critical hydraulic, instrumentation, and high-heat service environments.
Manufactured in accordance with ASTM A213, ASTM A269, ASME SA213, ASME 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 traceability, regulatory compliance, and acceptance for EPC, oil & gas, petrochemical, power generation, marine, and offshore projects worldwide.
