Nickel alloy Butt weld pipe fittings are used extensively
in applications where heat resistance and/or corrosion resistance
is required. Nickel Alloy Buttweld Pipe Fittings Manufacturers and Suppliers in this class are
designed to resist failure from both of these mechanisms. Nickel alloy
Butt weld pipe fittings are not suitable for high temperature sulphur
rich environments.This nickel alloy Butt weld pipe fittings
are frequently sold under trade name specifications but most are listed
in the Unified Numbering System. Common trade names are HASTELLOY,
INCOLOY, INCONEL, NICROFER, NICROM and NIMONIC. Nickel alloys Butt weld pipe fittings have higher strength
and longer life at elevated temperature than most alloys. The designer
however, must determine the expected life of each component and use
the appropriate creep and rupture strength in the design before selecting
Butt weld pipe fittings .
Nickel alloy Butt weld pipe fittings
are used in many applications where they are subjected to harsh environments
at high temperatures. Nickel alloys Butt weld pipe fittings offer
excellent corrosion resistance to a wide range of corrosive media.
However, as with all types of corrosion, many factors influence the
rate of attack. Nickel alloy Butt weld pipe fittings found to have
a profound effect on the thermal expansion of iron.

alloy for jet engine applications
Some corrosion-resistant variants in the Ni-Cr-Fe system include.
Nickel Alloy 625 Butt weld pipe fittings - The addition of 9% Mo plus 3% Nb offers
both high-temperature and wet corrosion resistance; resists pitting
and crevice corrosion.
Nickel Alloy G3/G30 (Ni-22Cr-19Fe-7Mo-2Cu) Butt weld pipe fittings -The increased
molybdenum content in these alloys offers improved pitting and crevice
corrosion resistance.
Nickel Alloy C-22 (Ni-22Cr-6Fe-14Mo-4W) Butt weld pipe fittings -Superior corrosion
resistance in oxidizing acid chlorides, wet chlorine, and other
severe corrosive environments.
Nickel Alloy C-276 (17% Mo plus 3.7W) Butt weld pipe fittings -Good seawater corrosion
resistance and excellent pitting and crevice corrosion resistance.
Nickel Alloy 690 (27% Cr addition) Butt weld pipe fittings -Excellent
oxidation and nitric acid resistance; specified for nuclear waste
disposal by the vitreous encapsulation method.
Iron-Nickel-Chromium Alloys Butt weld pipe fittings . This series of alloy Butt weld pipe fittings
has also found extensive use in the high-temperature petrochemical
environments, where sulfur-containing feedstocks (naphtha and
heavy oils) are cracked into component distillate parts. Not only
were these Butt weld pipe fittings resistant to chloride-ion stress-corrosion cracking,
but they also offered resistance to polythionic acid cracking.
Some alloys of commercial importance include:
Nickel Alloy 800 (Fe-32Ni-21Cr) Butt weld pipe fittings -The basic alloy in the
Fe-Ni-Cr system; resistant to oxidation and carburization at elevated
temperatures.
Nickel Alloy 800HT Butt weld pipe fittings -Similar to 800H with further modification
to combined titanium and aluminum levels (0.85 to 1.2%) to ensure
optimum high-temperature properties.
Nickel Alloy 801 Butt weld pipe fittings -Increased titanium content (0.75 to 1.5%);
exceptional resistance to polythionic acid cracking.
Nickel Alloy 802 Butt weld pipe fittings -High-carbon version (0.2 to 0.5%) for
improved strength at high temperatures.
Nickel Alloy 825 (Fe-42Ni-21.5Cr-2Cu) Butt weld pipe fittings -Stabilized with
titanium addition (0.6 to 1.2%). Also contains molybdenum (3%) for
pitting resistance in aqueous corrosion applications. Copper content
bestows resistance to sulfuric acid.
Nickel Alloy 925 Butt weld pipe fittings -Addition of titanium and aluminum to
825 composition for strengthening through age hardening.
Nickel alloys Butt Weld Pijpe Fittings are used for a wide variety
of applications, the majority of which involve corrosion resistance
and/or heat resistance. Some of these include:
