The function of the pipeline is mainly to transport liquids or other solids. It can be said to be the most commonly used equipment in our lives. 3 treatment methods for pipeline anti-corrosion. 1. What are the treatment methods for pipeline anti-corrosion? 1. Pipeline external anti-corrosion design Petroleum asphalt is the oldest pipeline anti-corrosion layer, […]
Before hot-dip galvanized steel pipe welding, the hot-dip galvanized steel pipe is mainly heated, and welding begins after temperature control for 30 minutes. The heating, solid layer temperature and heat treatment process of welding are automatically controlled by the temperature control cabinet of the heat treatment process. The far-infrared crawler heat treatment furnace is used […]
The buried pipeline uses plastic-coated steel pipe for the transmission line tower, which is composed of towers connected by tower pole devices. The pole tower is made of steel. The surface of the tower pole steel and the inner and outer surfaces of the tower pole are hot-dipped with a modified polyethylene plastic layer. The […]
1. Galvanized pipes and fixtures should be cleaned of foreign objects such as oil, residual salt, paint, etc. before heat treatment; 2. The fixtures used in the vacuum furnace for the first time should be degassed and purified in advance at a vacuum degree not lower than the required degree of the workpiece; 3. Workpieces […]
The transmission line tower of the buried pipeline adopts plastic-coated steel pipe, which is composed of towers connected by tower pole devices. The pole tower is made of steel. The surface of the tower pole steel and the inner and outer surfaces of the tower pole are hot-dipped with modified polyethylene plastic layer. The plastic-coated […]
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 […]
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 […]
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 […]
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 […]
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 […]
