Pipe heat-resistant heat-resistant
Supplier — AvekGlob Company — offers at a reasonable price from the manufacturer a pipe made of heat-resistant heat-resistant steels It is guaranteed timely delivery of metal products to any address specified by the consumer /
Pipes from heat-resistant grades of steel are used in those cases when the critical value for the working capacity of the product has an elevated temperature. Heat-resistant and heat-resistant steels are wear-resistant and exhibit increased resistance to large temperature fluctuations that can occur in pipelines. Characteristics of heat-resistant steel include corrosion resistance, creep resistance, oxidation resistance and reduced brittleness in a reducing environment, and with constant exposure to extremely high temperatures.
Urgency of application
Industrial applications of pipes made of heat-resistant and heat-resistant steels include flue and gas pipes of heating furnaces, pipes of heat exchangers and incinerators where the temperature can reach 1100 ° C.
Heat-resistant steels used for the production of pipes
An obligatory component of such materials is nickel and titanium, which together provide the necessary for long-term operation temperature characteristics. Most popular heat-resistant steels, which are commonly found in the oil and gas and petrochemical industry, have an optimal percentage of chromium (provides excellent corrosion resistance of steel) and molybdenum (for greater tensile strength and heat resistance),
Physical and mechanical properties
Features of physical and mechanical properties of heat-resistant and heat-resistant pipes are:
Maximum values of specific heat in the operational temperature range;
Minimum values of the coefficient of thermal conductivity, slightly changing with increasing operating temperature of the product;
The smallest changes in the values of the coefficient of thermal expansion;
Sufficient values of the temporary resistance limit (especially when pumping viscous media);
High values of the yield strength of the material;
Elevated values of impact strength.
Manufacturers of pipes from heat-resistant and heat-resistant steels supply products in a wide range of seamless and welded pipes. The material of such products should have good weldability.
Supplier — AvekGlob Company — offers to buy pipes from heat-resistant and heat-resistant steels in a wide range of brands and profiles at prices formed on the basis of European and world standards of production. Buy these products can be wholesale and retail. For regular customers, there is a flexible system of discounts.
