Nickel alloy seamless steel pipe INCOLOY 925, UNS NO9925, ALLOY 925 AP Seamless tube
Huashang
7507120000
This technical-focused INCOLOY 925 UNS NO9925 Nickel Alloy Seamless Steel Pipe is engineered for precision-critical applications demanding tight dimensional control and enhanced resistance to specific corrosive mechanisms. The alloy's microstructural stability, achieved through careful heat treatment and seamless manufacturing, ensures consistent performance in challenging operational conditions.
Advanced Corrosion Mechanism Resistance: The alloy's chromium content forms a protective oxide layer against oxidation, while molybdenum and copper work synergistically to combat pitting in chloride solutions. Titanium stabilizes the grain boundaries, preventing carbides from forming and reducing the risk of intergranular corrosion during welding.
High-Pressure Tolerance: With a minimum yield strength of 380 MPa and excellent creep resistance at elevated temperatures, this seamless pipe is suitable for high-pressure systems, such as subsea pipelines and refinery process lines where failure could have catastrophic consequences.
Precision Dimensional Control: Manufactured using cold-drawn or hot-rolled processes, the pipe meets stringent dimensional standards (e.g., ASTM B16.19 for tubing), with wall thickness tolerances within ±10% and outer diameter variations controlled to minimize installation issues.
Non-Magnetic Properties: INCOLOY 925's low magnetic permeability makes it ideal for applications sensitive to electromagnetic interference, such as in scientific instruments and certain marine navigation equipment.
In the energy sector, this pipe is used in enhanced oil recovery (EOR) projects, where it withstands the combined stresses of high-pressure CO₂ injection and corrosive reservoir fluids. In the pharmaceutical industry, its non-reactive surface and compliance with FDA standards make it suitable for handling active pharmaceutical ingredients (APIs) and corrosive cleaning agents in sterile environments. The marine renewable energy sector benefits from its use in tidal and wave energy converters, which are constantly submerged in abrasive seawater. Additionally, it is employed in the nuclear industry for secondary cooling systems, where resistance to chloride-induced SCC and long-term reliability are paramount.
Down-hole and surface well components for sour (containing hydrogen sulfide) crude oil and natural gas production.
Our pipe factory has 296 employees ,including 4 senior engineers, 18 engineers and 38 professional technicians .
We can produces 30,000tons of austenitic steel and duplex steel and nickel alloy pipes annually with 18 seamless production lines and 3 perforation production lines .
Our pipe factory has been certified to the ISO9001:2015 quality management system and certified by various classification societies (such as BV, ABS,CCS,DNV/GL,TUV,LR,KR etc)
