[PTFE] Rubber bellows expansion joints “good helper for sulfuric acid pipeline”

The official website of Shanghai Songjiang shock absorber Group Co., Ltd. introduces to you: [PTFE] Rubber bellows expansion joints “good helper for sulfuric acid pipeline” information. Songjiang group provides strong acid-base resistant Rubber bellows expansion joints products for sulfuric acid pipeline system of many chemical plants. It is mainly made of PTFE lining material, which plays a real role in acid and alkali resistance, and does not affect the original shock absorption, noise reduction, displacement and other effects of Rubber bellows expansion joints.

[PTFE] Rubber bellows expansion joints

Performance introduction of [PTFE] Rubber bellows expansion joints: it does not melt at the temperature of 250 ℃ and does not become brittle at the ultra-low temperature of – 260 ℃. PTFE is so smooth that even ice can’t match it; Its insulation performance is particularly good. A thick film of newspaper is enough to withstand 1500V high voltage. PTFE maintains excellent mechanical properties in a wide temperature range of – 196 ~ 260 ℃. One of the characteristics of PTFE polymer is that it remains brittle at low temperature. Chemical corrosion resistance and weather resistance PTFE is hardly corroded by any chemical reagent except molten alkali metal. For example, when boiled in concentrated sulfuric acid, nitric acid, hydrochloric acid or even aqua regia, its weight and properties do not change, and it is almost insoluble in all solvents. It is only slightly soluble in total alkanes (about 0.1g / 100g) above 300 ℃. PTFE is non hygroscopic, non combustible, extremely stable to oxygen and ultraviolet light, so it has excellent weather resistance.
