Why and how to do the antiseptic treatment for seamless pipe manufacturer

Although the performance of the seamless steel pipe is relatively good, since the seamless steel pipe is continuously used in the state of use, it is necessary to pay attention to protection and maintenance for the seamless steel pipe. One of the most prominent problems is the maintenance that everyone said. Because of the maintenance of seamless steel pipes, we must pay attention to various problems. For corrosion protection, we must take various measures to prevent them. Why should we prevent corrosion for seamless steel pipes? What is the specific process of anti-corrosion?

First: why the seamless steel pipe is preserved
Seamless steel pipe is a relatively high-end steel pipe, the price is very expensive, but after all, the raw material is also iron, it will also be long rust, which also affects the service life in the pipeline, so the seamless steel pipe anti-corrosion must be done before the pipeline construction. A process, for the seamless steel pipe is mainly to do 3pe anti-corrosion or epoxy coal bitumen anti-corrosion, the following notes on the anti-corrosion of seamless steel pipe.

Second: seamless steel pipe anti-corrosion process
Anti-corrosion of steel pipe according to the requirements of the drawings, epoxy tar pitch paint is used to cover the glass wire cloth, and the exterior coating is coated with anti-corrosion;
Outer wall construction process: pipe descaling → primer → first coat → second coat → wrapped glass cloth → top coat → top coat;
Inner wall construction process: pipe derusting → primer → first coat → second coat → third coat;

Seamless steel pipe anti-corrosion process flow chart
1. Pipe rust removal
Before the primer is applied, the surface of the pipe shall be cleaned of grease, ash, rust and iron oxide. The quality standard of sandblasting and rust removal is Sa2.5.

2. After the surface of the pipe is rusted, the primer is applied, and the time interval is not more than 8 hours. When the primer is applied, the base surface should be dry. The primer is evenly and satisfactorily coated, and there must be no clots or blistering. The ends of the tube shall not be painted within the range of 150 to 250 mm.

3. After the primer is dry, apply the topcoat and wrap the glass cloth. The time between the primer and the first coat should not exceed 24 hours.

Seamless steel pipe is a kind of important anti-corrosion type. In normal times, it is necessary to strengthen various technical advantages and anti-corrosion methods to avoid corrosion, so that seamless steel pipe will have better performance and use!
