HASTELLOY C-276（UNSN10276） PIPE / TUBE
Nickel-Chromium-Molybdenum-Tungsten Alloy for Severe Corrosive Environments
HASTELLOY C-276 pipe and tube are used in corrosive fluid handling, chemical processing, and heat exchange services where resistance to pitting, crevice corrosion, and chloride stress corrosion cracking is critical. The alloy also performs well in wet chlorine, hypochlorite, and chlorine dioxide environments.
As a professional Chinese nickel-based alloy manufacturer, we supply HASTELLOY C-276 pipes and tubes with stable chemistry, consistent mechanical properties, and flexible dimensional customization for global industrial users.
Typical supply range (custom sizes and tolerances available upon request):
Item | Range / Options | Notes |
Outside diameter (OD) | 6 – 610 mm | NPS sizes available; specify OD tolerance if critical. |
Wall thickness (WT) | 0.5 – 30 mm | Sch schedules by request; define minimum/maximum tolerance. |
Length | Up to 12 m | Fixed length or random length; cut-to-length by agreement. |
Type / process | Seamless / Welded | Seamless for critical service; welded available by size. |
End preparation | Plain end (PE) / Bevel end (BE) | End caps and protection available. |
NDT / testing | UT / ET / Hydro (as required) | Define inspection level for projects and code compliance. |
Delivery condition | Solution annealed (standard) | Pickled/bright depending on surface requirement. |
Dimension definition: OD × WT × LENGTH.
