Glass Lined Spacers
Glass Lined Pipes and tower
section:
The glass-lined tube is sprayed on the surface of the metal-steel blank by a silicon-containing
enamel glass glaze. After baking at a high temperature of about 900℃，the enamel glass glaze is
tightly bonded to the metal substrate, and the thickness of the metal substrate is uniformly covered
with a thickness of 0.8 to 0.2. The component of the glass-lined layer of mm. Pipe fittings are an
important component of material transfer. The surface of the glass-lined glassware is smooth and has
chemical stability similar to glass. It can withstand the corrosion of hydrofluoric acid and all
inorganic acids and organic acids other than hot phosphoric acid. The dissolution of all organic
solvents has sufficient rigidity and strength compared to the metal base of the glass-lined pipe
fittings, which avoids the secondary hazard caused by the brittle failure of glass-like pipe
fittings. The tight bond between the bismuth glass layer and the metal substrate does not cause the
non-metallic layer to fall off like a steel-lined PTFE pipe even under high temperature and high
vacuum conditions. Therefore, the glass-lined pipe is widely used in chemical, petrochemical,
pharmaceutical, dye, pesticide, food manufacturing, national defense and other industrial production
and scientific research where corrosion and cleanliness are required, which plays an irreplaceable
role effect.
The glass-lined pipe assembly can be divided into two categories: the first type consists of steel-
lined glass pipes, which form the main body of the glass-lined pipe assembly, such as glass-lined
tubes and elbows (including 30°, 45°, 60°,90°,180°elbow), three-way (including equal-diameter
tee and reducer tee), four-way (including equal-diameter four-way and reducer four-way), reducer
(including concentric Diameter pipe, eccentric reducer, reducer flange, spacer and flange cover; the
second type is the connection and sealing components of non-glass glass, such as glass-lined
equipment, loose flange, glass-lined Equipment gaskets, fasteners (including bolts, nuts, washers),
etc., the function is to complete the combination and assembly between the glass-lined pipe fittings
or the glass-lined pipe fittings in other pipes (equipment), so that they can be connected to
realize the pipeline Features.
Our
productivity and advantages:
1) It can produce DN25~DN2000 glass-lined pipe fittings and tower sections (DN250 and below are
generally less than 2000mm; DN300 and above can be up to 4000mm), and related enamel glass
accessories.
2) All glass-lined pipe fittings adopt a cold spray process, which requires workers to repeatedly
grind and refine the billet and glass glaze powder, and the moisture in the glass glaze powder is
naturally dry. The glass-lined tube under the operation of the technology has a large number of
firings, the porcelain layer is thin, the thickness of the porcelain layer is uniform, the bismuth
glass layer is tightly combined with the metal substrate, and the phenomenon that the dark foam and
the whole porcelain surface fall off are not easy to occur.
3) The simmering process carried out by the factory is the world's leading level, which can produce
national standards and more stringent European standards and DIN standards.
4) The factory has established a long-term cooperative relationship with the well-known European
enamel factory, and has long-term procurement of world-class enamel to ensure the firing of enamel
glass. The parts can be used stably for a long time under severe conditions such as chloroacetic
acid.

Pipe fitting is an important component of material transmission. The surface of glass lining layer of glass lining pipe fitting is bright and clean, with chemical stability similar to that of glass. It can withstand the corrosion of all inorganic and organic acids except hydrofluoric acid and thermal phosphoric acid. It can withstand the dissolving action of all organic solvents. Compared with glass pipe fittings, the metal of glass lined pipe fittings basically has enough rigidity and strength, which can avoid the secondary damage caused by the brittle failure of similar glass pipe fittings. Compared with steel lined tetrafluorocarbon pipes, due to the close combination of glass lined layer and metal matrix, it will not be like steel lined tetrafluorocarbon even under high temperature and vacuum conditions The non-metallic layer of the pipe falls off like that. Therefore, glass lined pipes are widely used in chemical industry, petrochemical industry, medicine, dyestuff, pesticide, food manufacturing, national defense and other industrial production and scientific research for their excellent performance, playing an irreplaceable important role.
