High-Precision Hastelloy C276 Tubes: ASTM B622/B619 Standard &
Custom Sizes for Demanding Chemical Processing
Introduction to High-Precision C276 Alloy Tubing
In the most aggressive industrial environments, where failure is
not an option, high-precision Hastelloy C276 tubing stands as a
benchmark for reliability. These tubes are not merely conduits;
they are critically engineered components manufactured to exacting
dimensional tolerances and metallurgical standards. Specifically
designed for applications involving severe corrosive challenges,
such as those found in chemical processing, pollution control, and
pharmaceutical industries, precision C276 tubes ensure system
integrity, safety, and longevity. This product information sheet
details our range of ASTM B622 (seamless) and ASTM B619 (welded)
high-precision tubing, emphasizing our capability to deliver
custom-sized solutions for your unique operational requirements.
Unmatched Material Properties: Why Hastelloy C276?
Hastelloy C276, a nickel-molybdenum-chromium superalloy with added
tungsten, is the material of choice for combating the most
formidable corrosive agents. Its exceptional performance stems from
a unique composition that provides:
Broad-Spectrum Corrosion Resistance: Excellent resistance to both
oxidizing and reducing media, including hot hydrochloric and
sulfuric acids. It is highly resistant to localized attack such as
pitting and crevice corrosion, and to stress corrosion cracking
(SCC) caused by chlorides.
Superior Thermal Stability: Maintains outstanding mechanical
properties and corrosion resistance over a wide temperature range,
from cryogenic temperatures up to 1000°C (1832°F).
Excellent Fabricability: Can be readily formed and welded using
standard techniques, making it suitable for fabricating complex
systems.
Compliance with Stringent ASTM Standards: B622 & B619
Our high-precision tubing is produced in strict compliance with
internationally recognized ASTM standards, guaranteeing material
quality, chemical composition, and mechanical properties.
ASTM B622: This standard covers seamless nickel and nickel-cobalt
alloy pipe and tube. Tubes produced to this standard are ideal for
high-pressure applications, offering homogeneous structure and
superior strength with no risk of weld-seam contamination.
ASTM B619: This standard covers welded nickel and nickel-cobalt
alloy pipe and tube. Utilizing advanced electric resistance welded
(ERW) or laser welding techniques, these tubes offer a
cost-effective alternative for many applications while maintaining
excellent corrosion resistance and dimensional precision.
Our manufacturing process ensures full traceability from melt to
final product, with each batch accompanied by a Mill Test
Certificate (MTC) certifying compliance to the required standard.
Our Manufacturing Capabilities: Delivering Precision and
Customization
We understand that off-the-shelf sizes rarely meet the precise
needs of complex engineering projects. Therefore, we specialize in
providing custom-sized high-precision tubing to your exact
specifications.
Key Capabilities Include:
Custom Outer Diameter (OD) and Inner Diameter (ID): We can produce
tubes to meet specific dimensional requirements for your system
layout.
Precise Wall Thickness: Control over wall thickness is critical for
pressure rating and flow dynamics. We manufacture to tight wall
thickness tolerances.
Multiple Lengths: Supplied in random, cut-to-length, or long single
lengths to minimize welds in your installation.
Surface Finish: A variety of finishes are available, including
annealed and pickled, mechanically polished, or bright annealed, to
meet hygienic or process-specific needs.
Rigorous Quality Assurance and Testing
Every length of tubing undergoes a comprehensive battery of tests
to ensure it meets the highest standards of quality and
performance. Our quality assurance protocol includes:
Dimensional Inspection: Verification of OD, ID, wall thickness, and
ovality using laser micrometers and ultrasonic testing.
Non-Destructive Testing (NDT): Eddy Current Testing (ECT) for
surface defects, followed by hydrostatic or pneumatic pressure
testing as required.
Chemical Analysis: Verification of alloy composition via spark
spectrometry.
Mechanical Testing: Determination of tensile strength, yield
strength, and elongation.
Critical Applications in Chemical Processing and Beyond
The combination of extreme corrosion resistance and high-precision
manufacturing makes our C276 tubes indispensable in numerous
sectors:
Chemical Processing Industry (CPI): Reactor coils, heat exchanger
tubes, condenser tubes, and feeder lines handling hydrochloric
acid, sulfuric acid, chlorine, and other aggressive catalysts.
Flue Gas Desulfurization (FGD) Systems: Absorber towers, mist
eliminators, and ducting that resist the corrosive sulfites and
chlorides in scrubber environments.
Pharmaceutical and Bio-Tech: Process piping and instrumentation
tubing where ultra-high purity, cleanability, and resistance to
corrosive sterilants are paramount.
Oil & Gas Production: Downhole instrumentation umbilicals, process
piping, and components exposed to sour gas (H2S), CO2, and
seawater.
Waste Incineration and Treatment: Handling aggressive combustion
by-products and chemical waste streams.
