International standards:According to international standards, the allowable deviation value of seamless pipe wall thickness should comply with the following regulations:1. For seamless steel pipes with wall thickness > or = 20mm, the allowable deviation value should be within plus or minus 10%;2. Fo

1. Coatings: Applying protective coatings on the carbon steel pipe's surface can help prevent corrosion. Coatings like epoxy, polyethylene, or fusion bond epoxy (FBE) provide a barrier against moisture and corrosive substances.2. Cathodic Protection: This method involves using a sacrificial anode or

1. Location: The storage area should be well-ventilated, dry and protected from the elements. It should also be easily accessible for inspecting, handling, and loading/unloading the pipes.2. Stacking: Pipes should be stacked in a way that prevents deformation or damage. They should be supported even

In the construction of water supply pipelines, plastic-coated steel pipes are widely used because of their good corrosion resistance and long service life. As an important component, coating materials play an important role in protecting steel pipes and extending their service life. The following wi
