The Construction: How Glass Lining Works

Okay, so we know what it is, but how is it made? The manufacturing process of glass lined stainless steel pipes is pretty fascinating, combining craftsmanship and technology. First, you start with the stainless steel pipe, typically chosen for its strength and resistance to external corrosion. Then comes the magic: the glass lining. This is applied in several stages. The inside of the pipe is meticulously cleaned and prepared to ensure a strong bond between the steel and the glass. Next, a specially formulated glass powder is applied. This powder is usually a mixture of silica, boric oxide, and other compounds designed to withstand specific chemical environments. After the glass powder is applied, the pipe is heated in a furnace to very high temperatures. This process, called firing, fuses the glass powder to the steel, creating a seamless, durable lining. The precise temperature control and the duration of the firing are crucial to ensure a uniform coating and a strong bond. The pipe then undergoes rigorous testing to verify the integrity of the glass lining. This includes spark testing to check for pinholes or imperfections and other tests to assess its resistance to thermal shock and chemical attack. The result? A pipe with an incredibly smooth, corrosion-resistant interior. The careful construction ensures reliability in demanding applications.
