Embodiment Construction

[0010] See figure 1 , the pipe (1) is a steel pipe body, including the inner wall re-lined with glass-lined glaze (1.1) and the flange surface (1.2) with through holes around it, according to the glass-lined process flow, the inner wall of the pipe (1) is sprayed Dry after spraying glass-lined (1.1) glaze slurry.

[0011] See figure 2 After spraying the glass-lined (1.1) glaze slurry and drying the pipe (1), after connecting its two ends with a special burning rack (4), hoist it into a new type of horizontal electric heating furnace that can be opened and closed by a mechanical crane ( In 2), it is positioned on the mechanical device (3) that can be rotated at both ends, and the glass-lined glaze is sintered while being rotated and heated, a new technology manufacturing method, and a large-scale glass-lined lined pipeline is manufactured.

Abstract

The present invention relates to a large-size glass lining pipe and its production method, belonging to the field of pipeline for transmission of media of petroleum, chemical material, natural gas and water source, etc. It is characterized by that the inner wall of steel pipe is lined with glass-glaze, so that said glass lining utilizes its firm binding capacity, smooth surface and good chemical stability free from electrostatic adsorption effect to effectively ensure smooth transmission of media of natural gas and water source, etc.

Description

technical field [0001] The invention relates to a pipeline for conveying mediums such as petroleum, chemical industry, natural gas and water source. In particular, it refers to a large glass-lined lined pipe and its manufacturing method. technical background [0002] With the construction of long-distance transmission pipeline projects such as natural gas and water sources in my country. Its transmission capacity is large, the main line of the pipeline is several thousand kilometers long, and the investment project is a large construction project with tens of billions of dollars. At present, epoxy powder or phosphorus sheet is used as the anti-corrosion layer of the inner wall of the pipeline, and the pipeline has a large diameter and a long length. Combining the excellent chemical stability and strong bonding force of glass-lined, it should be the most ideal anti-corrosion material. Due to the limitation of processing technology, only medium and small pieces of glass-line...
