How many years can the old cast iron heater be used?

In the north of China is very cold, this direction of the city's winter is longer, basically every household has to use to the heating, to be able to peacefully winter. Heater is the most common equipment in winter home heating, it can be divided into many types according to different materials, such as cast iron heater, steel heater, aluminum heater and so on. Among them, the cast iron heater is the oldest and most ancient heater shape.

Lifespan: its service life is about 30 years; price and corrosion resistance are better, but under the impact of new products, it has been outdated. Its service life is also related to many factors, and the environment at the time, and the protection measures at the time have a lot to do.

As a pressure vessel, the higher the pressure capacity, the safer. The new cast iron heater is made of rare earth cast iron, so the highest hot water working pressure of up to 1.0Mpa, fully meet the heating pressure requirements of medium and high-rise buildings, more safe and reliable. Than the traditional cast iron heater working pressure (generally 0.5Mpa, the highest 0.8Mpa) increased by at least 60-100%. At the same time it can also be used for steam heating system when used for steam system, the highest working pressure can reach 0.2Mpa.

Cast iron heater on the one hand, long service life, on the other hand, high recoverability, can be repeated recycling. Pig iron in the form of heaters to save, even if broken, can be used as raw materials back to the furnace smelting, high value retention, is a typical green building materials. And steel, aluminum and other heaters in the end of life, reuse value is very low.
