1.4404 Stainless Steel Seamless Hydraulic & Instrumentation Tubes
Leading manufacturers and suppliers of 1.4404 Stainless Steel Seamless Hydraulic & Instrumentation Tubes , ideal for high-purity and corrosion-sensitive applications. The low-carbon, molybdenum-alloyed grade resists intergranular, pitting, and crevice corrosion for reliable service.
1.4404 Stainless Steel Seamless Hydraulic & Instrumentation Tubes
Our 1.4404 Stainless Steel Seamless Hydraulic & Instrumentation Tubes (AISI 316L)
are designed for high-purity, corrosion-sensitive, and high-pressure applications where
superior cleanliness, enhanced weldability, and long-term performance are critical. The
low-carbon molybdenum-alloyed composition of Grade 1.4404 significantly
reduces the risk of intergranular corrosion after welding while maintaining excellent
resistance to pitting, crevice corrosion, and aggressive chloride environments.
The seamless, precision-manufactured construction ensures uniform wall thickness and
smooth internal surfaces, minimizing pressure drop and supporting efficient, contamination-free
flow in sensitive hydraulic and instrumentation systems. These tubes perform reliably
under continuous service, vibration, and elevated pressure conditions, making them ideal
for safety-critical and clean-service operations.
Commonly used in pharmaceutical and food processing plants, chemical and petrochemical
facilities, offshore platforms, semiconductor manufacturing, and industrial automation
systems, our 1.4404 stainless steel seamless tubes are produced and tested in accordance
with international standards to provide a durable, compliant, and cost-effective solution
for demanding and hygienic service environments.
