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 […]
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 […]
There is a cleaning and cleaning step in the maintenance of internal and external plastic-coated steel pipes, so the cleaning step is also very important. How can it be implemented well? Steel Pipe has some detailed introduction in these aspects. I hope everyone can learn this. Cleaning of internal and external plastic-coated steel pipes uses […]
Hot-dip pure zinc products, the code is GI. The characteristics of hot-dip pure zinc products are beautiful surface, good corrosion resistance and good processability. It is divided into two types, one is normal zinc flowers, and the other is no zinc flowers. Previous hot-dip galvanizing products always had some zinc splatter on the surface because […]
급수용 내외부 플라스틱 코팅 강관은 다음과 같은 특징이 있습니다: 첫째, 내부 및 외부 플라스틱 코팅 강관의 내부 표면은 플라스틱 코팅이되어있어 파이프 내부를 매끄럽게 유지하고 물 흐름에 대한 저항을 줄이며 물의 흐름을 증가시킬 수 있습니다. 또한 물이 [...] 때문에 [...]
