Although the performance of seamless steel tube is better, the protection and maintenance of seamless steel tube must be paid attention to because of the continuous use of seamless steel tube in service. One of the most prominent problems is what everyone says about maintenance. Due to the maintenance of seamless steel tubes, we must pay attention to various problems. In order to prevent corrosion, we must take various measures to prevent them. Why should seamless steel pipe be prevented from corrosion? What is the specific process of anti-corrosion?


First: Why do we keep seamless steel tubes?
Seamless steel pipe is a relatively high-end steel pipe, the price is very expensive, but after all, the raw material is iron, it will also grow rust, which also affects the service life of the pipeline, so seamless steel pipe must be anticorrosive before construction. First, the process, for seamless steel pipe is mainly to do 3PE anti-corrosion or epoxy coal tar pitch anti-corrosion, the following attention to seamless steel pipe anti-corrosion.


Second: Seamless Steel Pipe Antiseptic Technology
According to the requirements of the drawings, epoxy asphalt paint is used to cover glass fibre cloth, and the outer coating is coated with anticorrosive agent.
Exterior wall construction technology: pipeline rust removal primer first layer second layer wrapping glass cloth topcoat topcoat;
Internal wall construction technology: pipeline rust removal primer first layer second layer third layer;


Flow chart of anticorrosion technology for seamless steel pipe
1. Pipeline Rust Removal
Before using primer, grease, dust, rust and iron oxide should be cleaned on the surface of pipeline. The quality standard of sand blasting rust removal is Sa2.5.


2. After the surface of the pipeline is rusted, primer is applied, and the time interval is not more than 8 hours. When using primer, the bottom should be dry. The primer is uniformly and satisfactorily coated and must be free of clots or bubbles. The end of the tube should not be coated in the range of 150 to 250 mm.


3. After the primer is dried, coat it with paint and wrap it with glass cloth. The time between the primer and the first coating should not exceed 24 hours.


Seamless steel pipe is an important anti-corrosion type. In peacetime, we should strengthen various technical advantages and anti-corrosion methods to avoid corrosion, so that seamless steel pipe has better performance and use!
