Details of pickled phosphate seamless steel pipes commonly used in industrial projects

Pickled phosphate seamless steel pipes and steel pipes treated with pickled phosphates both involve the surface treatment technology of steel pipes. The following is a detailed introduction to these two types of steel pipes:

First, pickled phosphate seamless steel pipes

Pickled phosphate seamless steel pipes are steel pipes obtained by pickling and phosphating in the production or reprocessing of seamless steel pipes.

- Pickling: The main purpose of pickling is to remove scale, rust, and other dirt on the surface of the steel pipe, and to expose the metal on the surface of the steel pipe through the reaction of acid and metal, providing a good foundation for subsequent surface treatment (such as phosphating).

- Phosphating: Phosphating is the process of forming a layer of phosphate conversion film on the surface of the steel pipe. This conversion film has good adhesion and corrosion resistance, which can further improve the rust resistance and coating performance of the steel pipe.

Second, pickled phosphated steel pipes

Pickled phosphated steel pipes refer to the two surface treatment technologies of pickling and phosphating for the steel pipes that have been produced.

- Processing process: Similar to pickled and phosphate seamless steel pipes, this type of steel pipe also needs to be pickled to remove surface dirt, and then phosphate to improve its anti-rust and coating performance.

- Application scenarios: Pickled and phosphate steel pipes are widely used in various occasions that require anti-rust and coating treatment, such as refrigeration equipment, cold storage pipelines, hydraulic systems, etc.

Third, common characteristics and advantages

- Improve anti-rust performance: Pickling and phosphating can effectively improve the anti-rust performance of steel pipes and extend their service life.

- Enhance coating adhesion: The phosphating conversion film has good adhesion, which can enhance the bonding between the coating and the steel pipe surface and improve the coating effect.

- Beautify the appearance: The surface of the steel pipe treated with pickling and phosphating is smoother and more beautiful, which improves the overall quality of the product.

Fourth, precautions

- Processing quality: The quality of pickling and phosphating directly affects the anti-rust and coating performance of the steel pipe. Therefore, the processing process and quality need to be strictly controlled during the production process.

- Environmental protection requirements: Wastewater, waste gas, and other pollutants may be generated during pickling and phosphating. Therefore, corresponding environmental protection measures need to be taken during the production process to ensure compliance with environmental protection requirements.

In short, both pickled and phosphate seamless steel pipes and pickled and phosphated steel pipes are widely used on various occasions due to their excellent anti-rust and coating properties.
