1. What grades of Inconel are available and what are their main differences?
Answer:
We supply Inconel 600, 601, 625, 718, and 751:
Inconel 600: Excellent corrosion resistance, suitable for oxidizing environments, moderate strength.
Inconel 601: Good oxidation resistance at high temperatures (up to 1200°C), commonly used in furnaces.
Inconel 625: High strength, outstanding corrosion resistance, widely used in chemical and marine industries.
Inconel 718: High strength, creep and fatigue resistant, suitable for aerospace and power generation.
Inconel 751: Similar to 718, but with improved machinability and stress-corrosion cracking resistance.
2. What sizes and thicknesses are available?
Answer:
Our seamless and welded tubes/pipes are available in the following specifications:
Lengths: 2m, 2.5m, 4m
Wall thickness: 3mm, 6mm
Outer diameters: Customizable upon request to meet your engineering requirements.
We also provide cut-to-length options and can supply both hot-finished and cold-finished tubes.
3. What industries typically use these Inconel tubes and pipes?
Answer:
These nickel alloy tubes are used in high-performance and corrosive environments:
Aerospace: Engine components, heat exchangers, exhaust systems.
Chemical & Petrochemical: Piping for acids, caustics, and high-temperature reactions.
Power Generation: Boilers, turbines, nuclear systems.
Marine & Offshore: Subsea pipelines, desalination plants, and seawater equipment.
4. How are these Inconel tubes tested for quality?
Answer:
We ensure high quality through:
Chemical composition verification (spectroanalysis)
Mechanical testing: tensile, yield, elongation
Non-destructive testing (NDT): ultrasonic, eddy current, or hydrostatic pressure tests
Dimensional inspection: wall thickness, OD, straightness
Surface inspection: for defects like pits, cracks, or scale
5. How are Inconel tubes and pipes delivered and stored?
Answer:
Tubes/pipes are supplied cleaned, pickled, and oiled to prevent oxidation.
Packed in wooden crates or steel bundles, with protective plastic caps.
Stored in a dry, ventilated environment to avoid moisture and corrosion.
Custom packaging is available for long-distance shipping or marine transport.
