Compared to glass pipe fittings, glass lined steel pipes and fittings feature higher strength and durability. Therefore, glass lined piping system is widely applied in various industries including chemical, petrochemical, pharmaceutical, dyes, pesticides, food, etc., and plays an vital role in scientific research tasks where corrosion and clean work environment are two most important criteria.
We have the capability to apply silicon-containing enamel to steel surface. Through approximately 900°C high temperature firing, the uniform and dense enamel layer is permanently bonded on the metal surface, thickness of the layer ranges from 0.8mm to 2mm.
Qianqiao has established long-lasting partnership with European well-known porcelain enamel manufacturers. The reliable quality porcelain enamel supplied by these manufacturers enables our glass lined pipes and fittings to be stably used even in the harsh environments like chloroacetic acid.
