A nickel-iron-chromium alloy, Incoloy 800 pipe is designed to be strong, resistant to corrosion and
long-lasting at high temperatures. Even under extreme circumstances it is resistant to oxidation and
carburization. Preston Pipes and Alloys manufactures and supplies Incoloy 800 pipe, alloy 800 pipe, and
their high-performance variants worldwide. The stability and durability of the alloy are credited to the
controlled amounts of carbon, manganese, silicon, iron, chromium, aluminum-titanium and nickel in its
chemical composition. It is a trustworthy option for harsh condition because it provides good elongation
along with high tensile and yield strength.
Incoloy 800 pipe offers high-temperature strength and stability, making it a trusted choice for furnace
components and heat exchangers. Its corrosion resistance protects against acids, alkalis, and
chloride-rich environments. The alloy resists oxidation and carburization, which often damage metals in
hot settings. It is also weldable and machinable, easing fabrication. Strong creep and stress rupture
properties help it perform under high temperature and pressure for long periods. Reactors in chemical
processing, steam turbine parts in power plants, furnace tubes and heat exchangers for petrochemicals
and vital nuclear plant pipes are among the common applications. It also finds use in pulp and paper
industries and heat treatment equipment.
In accordance with ASTM/ASME B407, B514, B515 and comparable SB grades, we offer high quality Incoloy
800 pipe. We offer a wide range of pipes including seamless, welded, ERW, fabricated, CDW, and 100%
X-ray welded types. Sizes range from 6 mm OD to 914.4 mm OD, with up to 24” NB. Thickness schedules
cover SCH 5 to SCH XXS. Ends are available as plain, beveled, threaded one end, or threaded both ends.
Length options include single random, double random and cut to length. Depending on the needs of the
client, finishes can be bright polished, annealed, pickled, or 2B and No. 1. We also stock Incoloy 800H
pipe, Incoloy 800HT pipe, and their alloy 800H pipe and alloy 800HT pipe variants in multiple sizes.
Every incoloy 800 pipe and incoloy 800ht pipe undergoes strict quality checks before dispatch.
Destructive and non-destructive testing, visual inspection, PMI, chemical and mechanical reports and
100% radiography are among the tests. We provide EN 10204/3.1B, 3.1, and 3.2 mill test certificates
along with NABL-approved lab reports and third-party inspection if required. Using wooden boxes, crates,
pallets, cartons and shrink-wrap for safe transportation, the packaging satisfies export requirements.
As an experienced incoloy 800 pipe supplier we ensure timely delivery and dependable quality for every
order.
