relevance

Thanks to the optimal technological and operational parameters, the HN77 TUR pipe copes with the hardest work and actively resists the influence of most harmful industrial factors, ensuring the reliability and durability of the operation of important equipment. Alloys based on nickel and chromium have long been a fundamental material for many manufacturing industries.

Composition and properties

The chrome nickel alloy tube ХН77ТЮР differs with a whole complex of high performance characteristics, due to the perfectly balanced composition.

Percent composition according to GOST 5632−72
Alloy FROM Mn Fe P S Ni AT Cr Al Ti Si Pb Impurities
ХН77ТЮР ≤0.07 ≤0,4 ≤1 ≤0.015 ≤0.07 70--77,4 ≤0.01 19−22 0.6−1 ≤0,02 2.4−2.8 ≤0.6 ≤0.001 ≤0.015

In addition, it should be noted that nickel in the alloy KhN77TYUR provides a sufficiently high ductility, which facilitates the processing and installation of equipment. Such pipes are highly resistant to corrosion and significant heat resistance, which allows them to be used at elevated temperatures and the presence of an aggressive environment in the exploitation zone.

Application of

The scope of this type of pipes is quite diverse, they are used for the manufacture of various pipe fittings, the production of heat exchangers. Pipes brand ХН77ТЮР are used in the pulp and paper, oil and gas and processing industries for the production of elements of increased strength, designed to work in an aggressive environment. In the engineering industry, such pipes are relevant for the manufacture of parts of gas turbine engines, designed for use at operating temperatures up to 750ºC. In addition to the industrial sphere, durable and beautiful material has proven itself in everyday life. Excellent hygienic qualities make it possible to widely use such pipes for water supply systems.
