HN35VT alloy tube, circle
Metal industrial construction today are forced to work in very hard conditions. Steel brand HN35VT (EI612) refers to a high-alloy chromium-nickel superalloy basis. Used for the production of lightly loaded parts, designed to operate at t ° 900−1000 ° C. This steel limited weldability. Welding products should be performed after heating to 250 ° C with the final heat treatment.

By manufacturing precision tube may be conventional and improved accuracy. Temperature semi pull the shoes produced in the range 1170 — 850 ° C, cooling takes place in air. Rolled tubes: seamless, hot-rolled, heat and cold, which are used for industrial pipelines and building structures. Electro Pipe HN35VT hard welded. For high quality weld is required preheating up to 250 ° C with a final annealing to relieve residual stresses. Recommended for manual arc welding electrodes KTI-762. The tubes can be: profile with a rectangular, oval or square cross-section. Pipe Manufacturing is standardized by the following guests: 30 245−2003, 10 706−76 10 705−80, 380−94, 8639−82, 13, 663−86, 1050−88, 8645−68, 8642−68. Each standard stipulates the characteristics of one product, such as a pipe with a specific section.
HN35VT pipes are relevant to the processing industry and the petrochemical industry. Advantages alloy can produce the product long life, operated at temperatures up to 850 ° C. When a stronger heating at the surface begins to form scale. Trubs of the alloy used in all areas for feeding gas or liquid heat exchange assembly systems.
Depending on the customer pipe may be heat-treated with different kinds of threads: a cylindrical knurled or cut thread and the unthreaded. Dimensions of pipes, as well as their range of products correspond to GOST 3262−75. The tube may have different lengths. Measuring length — 12.4 m, a multiple dimensional length — tube whose length is calculated in the dimensional limits, at the same time for each cut to 5 mm made allowance, and longitudinal deviation of the pipe over the entire length should not exceed 10 millimeters. pipes also produces random length within dimensional.
