Glass Lined Pipe Fitting manufacturer

Glass lined pipe fittings are widely used equipment components in industries such as chemical, pharmaceutical, and food. Their characteristic is that the surface is coated with a layer of glass glaze, which enhances the corrosion resistance and smoothness of the pipe fittings. Below, the  glass lined pipe fitting manufacturer will introduce their material composition, which mainly includes the following aspects:
1、 Base material

The substrate is usually made of metal pipes, which can be steel pipes, cast iron pipes, or stainless steel pipes. The substrate material of these glass lined pipe fittings has good mechanical properties and pressure resistance, which can provide stable support for the glass lined layer.

2、 Enamel glass layer material
The core part of the enamel glass pipe fittings is the enamel glass layer, which is made of high borosilicate glass material. High borosilicate glass has excellent chemical stability, corrosion resistance, wear resistance, and high temperature resistance. In the manufacturing process, molten borosilicate glass is lined into the preheated inner wall of a metal pipeline using a special method, so that the glass firmly adheres to the inner wall and is in a certain compressed state, thus forming a composite structure of steel and glass.
3、 Material selection and standards
The selection of materials should strictly follow the relevant national or industry standards. The substrate material should ensure a smooth surface, free from rust, oil stains, and other impurities, and undergo appropriate pretreatment to improve the adhesion between enamel glaze and metal substrate. The material of the enamel layer should have high purity and good processing performance to ensure the quality and performance of the enamel pipe fittings.
4、 Additional processing materials (if any)
In certain specific application scenarios, glass lined fittings may require additional treatment to improve their performance. For example, anti-corrosion treatment or other protective layers can be applied to the outer surface of the enamel layer to extend its service life. The selection of these additional processing materials should also be determined based on specific application requirements and standards.
In summary, the material composition of glass lined pipe fittings mainly includes substrate materials, glass lined layer materials, and possible additional processing materials. The selection and processing techniques of these materials are crucial for ensuring the quality and performance of glass lined pipe fittings.
