The inner part of the heating pipe manufacturer directly affect the quality of the electric heating tube life spans
Single-head heating tube heating wire as the inner part of the electric heating tube, his choice directly affect the quality of the electric heating tube life spans. To we said yesterday, as can be used in the electric heating tube electrothermal SiDou is a must request, specific requirements: single-head heating tube electric heating tube is introduced to the requirement of internal heating wire, so today, let's say, if meet the requirement of electric heating wire, and how to choose for different electric heating tube.
In single head heating tube electric heating tube manufacture process, now the domestic first for the resistance wire of electric heating tube choose 2 broad categories: nichrome wire and iron chromium aluminum wireNichrome wire and iron chromium aluminum wire says below:
1, nickel chromium heating wire primary advantages and disadvantages:
Low interest: high temperature strength is relatively high iron chromium aluminum, under high temperature and use is not easy to deformation, its structure is not easy to change, plasticity is good, easy to revise, its high emissivity, nonmagnetic, strong corrosion resistance, long life.
Low faults: because choose metal material is relatively scarce, so the price is higher than that of iron chromium aluminum products of this series up to a few times, use the temperature was lower than those of iron chromium aluminum.
2, iron chromium aluminum heating wire primary advantages and disadvantages:
Low interest: iron chromium aluminum heating wire used high temperature, the highest use temperature can reach 1400 degrees, cr21a16nb (0, 0 cr27a17mo2, etc.), using the full length, high surface load, good oxidation resistance, high resistivity, low price, etc.
Low low faults: first is the high temperature strength, followed by using temperature increases its plasticity, components easy to deformation, not easy to bend and corrections.
