Manufacturers and suppliers of 317H Stainless Steel Seamless Hydraulic & Instrumentation Tubes, engineered for high-temperature, high-pressure, and highly corrosive service environments in petrochemical plants, refineries, power generation facilities, and chemical processing systems..
Our 317H Stainless Steel Seamless Hydraulic & Instrumentation Tubes
are engineered for demanding high-temperature and highly corrosive environments where
superior mechanical strength, enhanced creep resistance, and long-term operational
reliability are essential. The high-carbon composition of Grade 317H
improves structural stability at elevated temperatures, while the increased
molybdenum and chromium content delivers exceptional protection against pitting,
crevice corrosion, and stress corrosion cracking in aggressive chemical and
chloride-rich service conditions.
The seamless, precision-manufactured construction ensures uniform wall thickness and
smooth internal surfaces, reducing pressure losses and improving flow efficiency in
critical hydraulic and instrumentation systems. These tubes maintain performance
under high pressure, thermal cycling, and continuous heat exposure, making them ideal
for safety-critical fluid control and precision measurement applications.
Widely used in petrochemical and chemical processing plants, refineries, power
generation facilities, offshore and marine systems, and high-temperature industrial
operations, our 317H stainless steel seamless tubes are manufactured and tested to
international standards to deliver a durable, high-performance, and cost-effective
solution for harsh, heat-intensive, and corrosive service environments.
Our 310L Stainless Steel Seamless Hydraulic & Instrumentation Tubes are trusted across major industrial cities in India, including Mumbai, Chennai, Pune, and Ahmedabad, supporting petrochemical plants, refineries, power generation facilities, and critical infrastructure projects that demand reliable, high-temperature and corrosion-resistant tubing solutions.
Throughout the Middle East, we supply the UAE (Dubai, Abu Dhabi, Sharjah, Ajman, and Ras Al Khaimah), Saudi Arabia, Qatar, Kuwait, Oman, Bahrain, Iraq, Jordan, and Lebanon. Our 310L stainless steel seamless tubes are widely used in oil & gas processing, water treatment facilities, and EPC projects operating under extreme heat, pressure, and corrosive service conditions.
In Europe, our tubes serve Italy, Germany, Spain, France, the United Kingdom, Turkey, Greece, Austria, and Eastern European markets, where precision engineering and high-temperature performance are essential. Across Africa, the Americas, and the Asia-Pacific region—including the United States, Canada, Brazil, Mexico, South Africa, Nigeria, Singapore, Malaysia, Thailand, and Australia—our 310L Stainless Steel Seamless Hydraulic & Instrumentation Tubes support chemical processing plants, power stations, offshore platforms, heavy manufacturing, and thermal processing industries.
Wherever you operate—Doha, Dubai, London, Houston, Singapore, or Sydney—Seminox Pipes & Tubes delivers premium-quality 310L Stainless Steel Seamless Hydraulic & Instrumentation Tubes, manufactured and certified to international standards to ensure precision, full traceability, and long-term performance in critical fluid control and high-temperature instrumentation applications worldwide.
Manufactured 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 higher carbon content of 317H stainless steel improves high-temperature strength and creep resistance, making these tubes ideal for heat-intensive and high-pressure hydraulic and instrumentation systems.
The increased molybdenum content provides excellent resistance to pitting, crevice corrosion, and chloride-induced attack, ensuring long-term performance in aggressive chemical, marine, and petrochemical environments.
Precision-finished internal surfaces reduce friction, minimize pressure loss, and enhance flow stability for sensitive instrumentation and process control systems.
Maintains mechanical integrity and corrosion resistance under extreme temperatures, thermal cycling, and oxidizing industrial service conditions.
Engineered for extended durability, reduced downtime, and lower lifecycle costs in petrochemical plants, refineries, power generation facilities, and high-temperature process industries.
317H 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 enhanced high-temperature strength, superior corrosion resistance, and tight dimensional tolerances for high-pressure, high-heat hydraulic and instrumentation service 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 and high-temperature performance 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 critical, corrosive, and elevated-temperature 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, petrochemical, power generation, refinery, chemical processing, and offshore projects worldwide.
