Main reasons for stainless steel press fittings pickling：
Removal of oxidized skin and rust spots: in the production and processing of stainless steel pipe fittings, the surface often generates a layer of oxidized skin and rust spots on the surface of press fittings, and these substances will affect the appearance and performance of the products. Pickling is an effective way to remove these surface impurities.
Removal of welding oxides: stainless steel propress fittings in the welding process will generate some high-temperature oxides, these oxides, if not removed, will affect the quality of welded joints and corrosion resistance.
Removal of other impurities: oil, dust, metal debris and other impurities that may remain in the pipe fittings production process also need to be removed by pickling to ensure a clean surface.
Role
Improve surface finish: Pickling can significantly improve the surface finish of stainless steel lpipes and fittings , making it smoother and more aesthetically pleasing, which is especially important for decorative applications.
Enhances corrosion resistance: The removal of oxidized skin and impurities from the surface of stainless steel propress fittings and welded pipes restores its natural resistance to corrosion and extends its service life. Pickling also removes iron impurities from the surface, reducing the generation of corrosion spots.
Improve welding performance: the clean surface of stainless steel plumbing fittings after pickling facilitates subsequent welding operations and improves the quality and consistency of welded joints.
Preparation for further processing: pickling is the pretreatment step of many surface treatment processes (such as electroplating, painting, etc.), a clean surface can ensure the effect of subsequent processing and adhesion.
Removal of surface contaminants: During the manufacturing process of stainless steel pipe fittings, the surface may be contaminated with oil, metal dust and other contaminants, which can be completely removed by pickling to ensure a clean surface.
Automatic pickling production line of Franta company.
Franta has introduced fully automated production lines. These automated pickling lines have the following features and advantages:
Efficient and Stable: The automated equipment is able to carry out the pickling operation continuously and efficiently, ensuring that each workpiece can achieve a consistent treatment effect.
Precise control: The automated system can accurately control the pickling time, acid concentration and temperature to optimize the pickling effect and reduce the error caused by human operation.
Environmental protection and safety: The modernized pickling production line is equipped with advanced waste liquid treatment system, which can effectively treat and recycle the waste liquid generated during the pickling process, reduce environmental pollution and improve safety.
Cost reduction: By improving production efficiency and product quality and reducing scrap rate, automated production line can significantly reduce production costs.
Increase production capacity: The automated production line can significantly increase production capacity to meet the market demand for high quality stainless steel fittings and pipes.
Through the introduction of fully automatic pickling production line, Franta not only improves the product quality and production efficiency, but also enhances the competitiveness of the enterprise in the stainless steel press fittings and thin wall pipes products industry.
