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 [...]

용접 기술 측면에서 직선 심 강관은 저항 용접 직선 심 강관과 서브 머지드 아크 용접 직선 심 강관으로 나눌 수 있습니다. 저항 용접 직선 심 강관은 고주파 용접 직선 심 강관, 중주파 용접 직선 심 강관 및 저주파 용접 [...]으로 더 나뉩니다.
산화는 강철이 가열되면 용광로 가스에서 CO2, H2O, O2의 작용으로 인해 산화되어 산화철 스케일을 형성하는 것을 의미합니다. 강철의 약 0.5%-3%가 가열 될 때마다 산화되어 산화철 스케일을 형성하여 (즉, 연소 손실) 수율을 감소시킵니다. 에서 [...]
