Application of plastic-coated steel pipes

Plastic-coated steel pipes are used everywhere in life, such as building water supply pipes, fire water supply pipes, special pipes for coal mines, hot spring anti-corrosion and thermal insulation pipes, and cable protection pipes commonly seen in modern life. Common steel-plastic composite pipes are actually mainly plastic-lined steel pipes and plastic-coated steel pipes. The following […]

Safety Precautions For Anti-corrosion Steel Pipe Construction

3PE anti-corrosion steel pipe spraying technology, most domestic 3PE anti-corrosion steel pipe production technology adopts the production and processing technology of “epoxy powder spraying, adhesive and polyethylene lateral extrusion, winding rolling”, because the powder and electrostatic thermal spraying method does not require rolling system, thus solving the problem of thin weld coating of spiral structure […]

Características e inspección de tubos de acero con revestimiento interior y exterior de plástico

Internal and external plastic-coated steel pipes for water supply have the following characteristics: First, the inner surface of the internal and external plastic-coated steel pipes has a plastic coating, which can keep the inside of the pipe smooth, reduce the resistance to water flow, and increase the flow of water. In addition, because the water […]

Storage Standards For Anti-corrosion Steel Pipes

I believe many people have doubts about the storage of anti-corrosion steel pipes. Let’s take a look at the storage of anti-corrosion steel pipes. 1. The appearance of anti-corrosion steel pipes entering and leaving the warehouse needs to be inspected as follows: ① Inspect each root to ensure that the surface of the polyethylene layer […]

Drying Temperature Of Hot-dip Galvanized Steel Pipe

When plated parts need to be stacked closely together for storage and transportation, adequate precautions should be taken to prevent white rust. Maintaining a low humidity environment around the plated parts and ensuring adequate ventilation between stacked plated parts can prevent white rust. Minimize it. Specific precautions are described below. one. Surface treatment can be […]

“Zinc flowers” Of Hot-dip Galvanized Pipes

The hot-dip coating surface of seamless steel pipes will have crystallization patterns of the coating metal during solidification. This crystallization pattern is especially obvious for galvanized seamless pipes, showing the appearance of beautiful zinc crystals, thus becoming the appearance of hot-dip galvanized seamless pipes. This important feature is usually called “zinc flower”. When the galvanizing […]

Características de las capas galvanizadas convencionales

Productos de zinc puro por inmersión en caliente, el código es GI. Las características de los productos de zinc puro por inmersión en caliente son una superficie bonita, una buena resistencia a la corrosión y una buena procesabilidad. Se divide en dos tipos, uno es de flores de zinc normales, y el otro es sin flores de zinc. Los productos galvanizados en caliente anteriores siempre tenían algunas salpicaduras de zinc en la superficie porque [...]

Características e inspección de tubos de acero con revestimiento interior y exterior de plástico

Los tubos de acero revestidos de plástico internos y externos para el suministro de agua tienen las siguientes características: En primer lugar, la superficie interior de la tubería de acero revestida de plástico interna y externa tiene un revestimiento de plástico, que puede mantener el interior de la tubería lisa, reducir la resistencia al flujo de agua, y aumentar el flujo de agua. Además, como el agua [...]
