Stainless round steel pipes are a kind of hollow long strip round steel, mainly used in petroleum, chemical and other industrial pipeline and mechanical structure components. In addition, the bending and torsional strength of the same weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures.
Alkali metals have a corresponding [Noble gas] ns 1 electronic configuration. They occupy the first column of the periodic table. Alkali elements are Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Ru), Cesium (Cs) and Francium (Fr) occupying successive periods from first to seven. Francium is a radioactive element with very low half-life.

3/8/2015· CHEMICAL PROPERTIES OF ALKALI METALS. Posted on August 3, 2015 by Administrator. Alkali metals exhibit very high chemical reactivity because—. i) Low IE1, so they form M+ easily. ii) Low heat of atomisation so their vapour are formed easily. iii) High heat of hydration, so a lot of energy is available to break existing bonds.

The working fluid of a high temperature heat pipe is generally alkali metals, and their evaporations of latent heat are very large, and the saturation pressure is smaller at high temperature, then the case strength is not a problem. The high and super high temperature heat pipe can work over 500°C, 1000°C, 1500°C or much higher.
