One-time enameling and low-temperature firing glass lining glaze for oil field pipeline corrosion prevention, as well as preparation method and applications

Abstract

The invention belongs to the technical field of glass lining glaze, and specifically discloses a one-time enameling and low-temperature firing glass lining glaze for oil field pipeline corrosion prevention, and a preparation method and applications thereof. The glass lining glaze is prepared from the following components in percentage by weight: 30 to 50% of SiO2, 5 to 20% of B2O3, 1-5% of Al2O3,2-5.5% of Li2O, 4 to 16.5% of K2O and Na2O; 1-6% of CaO, 1-1.5% of MnO2, 0.3 to 2% of CoO, 0.5 to 2% of NiO, 1 to 8% of CaF2, 1.2 to 7.5% of TiO2, 0.5 to 4% of ZrO2, 0.5 to 5% of ZnO, 0.5 to 5% of SnO2, 0 to 4% of MoO3, 0 to 3% of SrO, 0 to 2.5% of CeO2 and 0.5 to 8.5% of BaO. The highest firing temperature of the glass lining glaze is lower than 800 DEG C, an anticorrosive coating layer can be manufactured through one-time enameling, the production efficiency of the pipeline anticorrosive coating layer can be greatly improved, and the glass lining glaze is suitable for corrosion prevention ofoil field pipelines.

Description

technical field [0001] The invention belongs to the technical field of glass-lined glaze, in particular relates to the anticorrosion of metal pipelines used in oil fields, and specifically discloses a glass-lined glaze for oilfield pipeline anticorrosion with one-time enamel and low-temperature firing as well as its preparation method and application. Background technique [0002] At present, the commonly used glass-lined anti-corrosion chemical equipment generally has two layers of bottom glaze, and the firing temperature is high, generally above 900°C, which is easy to cause high-temperature deformation of the pipeline and waste fuel; the bottom glaze needs to be fired several times, and the production time is long. The production speed is slow; the glaze slurry needs to be sprayed, then dried and fired, and the production process is complicated. Therefore, lowering the firing temperature of glass-lined anticorrosion equipment, increasing production efficiency, and simplif...
