WSA-湿式法による硫酸 — 酸除去用スパイラルチューブ（酸除去用スパイラルチューブ WSA CONDENSER – メインチューブブロック1用ガラス製スパイラル）

The acid removal tube in the WSA wet acid production technology system is made of quartz glass, which has the following key property advantages: Excellent resistance to thermal shock: The coefficient of linear expansion is extremely small and is only 1/10-1/20 of the coefficient of borosilicate glass, so when operating, cracks or pipe breakage are practically excluded. High heat resistance: The normal operating temperature reaches 1200°C, and the limit is 1300°C. Thoughtful acid resistance: Effectively resists acid corrosion, with long-term operation on the surface does not form clogs.
