What is the Surface Polished Process?

The surface polishing process of metal pipeline is to polish the surface of pipeline by mechanical or chemical methods to improve its appearance quality and performance. The polishing process can be categorised into mechanical polishing and chemical polishing.

Mechanical polishing consists of a multi-stage grinding and polishing step in which grinding wheels or polishing heads of different particle sizes are used to progressively buff the metal surface until the desired smoothness and lustre are achieved. This process usually employs abrasives and grinding media, and polishing is achieved by rotating or vibrating devices.
Another method is chemical polishing, which is achieved by applying an acidic or alkaline chemical solution to the metal surface to eliminate oxidised layers and uneven surface impurities. This method is commonly used for certain metal materials such as stainless steel, copper and aluminium.
The polishing process improves the quality of the appearance of metal pipes by enhancing their lustre and smoothness. This not only makes them more decorative and aesthetically appealing, but also improves their corrosion resistance, ease of cleaning and availability for specific applications.



Polished Stainless Pipe

Polishing process is an indispensable step in the manufacturing process of stainless steel pipes. With materials such as grinding wheels, cloth wheels and polishing pastes of different coarsenesses and finenesses, the craftsmen are able to precisely control the finish and luster of the polished pipes. From a rough, frosted finish to a smooth, mirror-like luster, stainless steel polished pipes are available in a wide range of surface options to meet the needs of different applications.

 

Stainless steel polished pipes are used in a wide range of applications. In the chemical and petroleum industries, their excellent corrosion resistance makes them ideal for the transportation of corrosive liquids. In the food and beverage industry, the smooth surface of polished pipes helps to clean and sanitize, meeting stringent hygiene standards. In addition, stainless steel polished pipes are widely used in decorative and architectural applications, such as hotel lobbies and shopping mall display cases, adding beauty and ambience to the space with their elegant appearance and modernity.
