Manufacturers and suppliers of 904L Stainless Steel Seamless Hydraulic & Instrumentation Tubes, engineered for extremely corrosive, high-purity, and chemically aggressive service environments in chemical processing plants, petrochemical facilities, pharmaceutical units, and power generation systems.
Our 904L Stainless Steel Seamless Hydraulic & Instrumentation Tubes
are engineered for extremely corrosive and chemically aggressive environments where
superior purity, long-term reliability, and exceptional resistance to localized
corrosion are essential. The super austenitic composition of Grade 904L,
featuring high levels of nickel, chromium, molybdenum, and added copper, delivers
outstanding protection against pitting, crevice corrosion, and stress corrosion
cracking in chloride-rich, acidic, and high-purity process service conditions.
The seamless, precision-manufactured construction ensures uniform wall thickness and
ultra-smooth internal surfaces, minimizing contamination risk, reducing pressure
losses, and improving flow efficiency in critical hydraulic, instrumentation, and
chemical transfer systems. These tubes maintain performance under continuous
exposure to aggressive acids, elevated temperatures, and demanding pressure cycles,
making them ideal for safety-critical and high-integrity process applications.
Widely used in chemical processing plants, petrochemical facilities, pharmaceutical
and biotech industries, desalination systems, offshore platforms, and power
generation units, our 904L stainless steel seamless tubes are manufactured and tested
to international standards to deliver a durable, corrosion-resistant, and
high-performance solution for the most challenging industrial environments.
Our 904L Stainless Steel Seamless Hydraulic & Instrumentation Tubes are trusted across major industrial cities in India, including Mumbai, Chennai, Pune, and Ahmedabad, supporting chemical processing plants, petrochemical facilities, pharmaceutical manufacturers, power generation units, and critical infrastructure projects that demand ultra-high corrosion resistance, material purity, and long-term performance in aggressive service environments.
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 904L stainless steel seamless tubes are widely used in oil & gas processing, desalination plants, chemical handling systems, water treatment facilities, and EPC projects operating under extreme heat, pressure, and highly corrosive chemical exposure.
In Europe, our tubes serve Italy, Germany, Spain, France, the United Kingdom, Turkey, Greece, Austria, and Eastern European markets, where precision engineering, high material purity, and superior resistance to acids and chlorides 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 904L Stainless Steel Seamless Hydraulic & Instrumentation Tubes support chemical plants, offshore platforms, pharmaceutical production units, power stations, heavy manufacturing, and high-integrity process industries.
Wherever you operate—Doha, Dubai, London, Houston, Singapore, or Sydney—Seminox Pipes & Tubes delivers premium-quality 904L Stainless Steel Seamless Hydraulic & Instrumentation Tubes, manufactured and certified to international standards to ensure precision, full traceability, and long-term reliability in critical fluid control, high-purity, and highly corrosive service 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 highly accurate instrumentation performance.
904L is a super austenitic stainless steel with high nickel, chromium, and molybdenum content, providing exceptional resistance to pitting, crevice corrosion, and general corrosion in highly aggressive chemical, acidic, and chloride-rich environments.
Designed to perform in sulfuric, phosphoric, and other harsh chemical processing conditions, these tubes offer superior protection against stress corrosion cracking and chemical attack in critical service applications.
Precision-finished internal surfaces reduce friction, minimize pressure loss, and enhance flow stability for sensitive instrumentation, dosing, and high-purity process control systems.
Low carbon content and stabilized chemistry improve weldability and reduce the risk of intergranular corrosion, ensuring strong, clean weld joints in pharmaceutical, chemical, and high-integrity piping systems.
Engineered for extended durability, reduced downtime, and lower lifecycle costs in chemical plants, desalination facilities, offshore platforms, and high-purity industrial process environments.
904L 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 super-austenitic, homogeneous microstructure with exceptional resistance to strong acids, chlorides, and stress corrosion cracking, along with tight dimensional tolerances for high-purity, high-pressure, and highly corrosive 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 (Ni, Mo, Cu, Cr content), mechanical and corrosion resistance 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 highly corrosive and chemical-intensive 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, chemical processing, pharmaceutical, power generation, and offshore projects worldwide.
