The material of the reservoir for the reservoir
1. copper tube: T2 is mainly composed of 99.9% copper, and drawn copper tube GB/T17791-1999. The melting point of copper is 1083 degrees, and it has good plasticity, electrical conductivity and thermal conductivity. The linear expansion coefficient is 900 degrees 19.3/ 10, and the processing technology is electrolytic copper-smelting-copper ingot-peeling-extrusion-drawing.

2. Steel plate: SPCC, ST 12, ST 14, SPHC deep-drawn steel plate, with plasticity greater than 28% and tensile strength greater than 270MPa. Melting point 1400- 1500 degrees, linear expansion coefficient 1000 degrees or more 17.6/ 10.

3. Steel pipe: SPCC high frequency welded pipe, Q 195. Processing technology: steel plate-longitudinal shearing-coiling-high frequency welding-debonding-forming.

4. Mesh: stainless steel wire 0Cr 18Ni9, GB/T5330-2003, mesh number (25.4mm mesh number).
