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 […]

In termen van lastechnologie, kunnen de rechte buizen van de naadstaal in weerstand gelaste rechte buizen van de naadstaal en ondergedompelde booggelaste rechte buizen van de naadstaal worden verdeeld. Weerstand gelaste rechte naad stalen buizen zijn verder onderverdeeld in hoge frequentie gelaste rechte naad stalen buizen, gemiddelde frequentie gelaste rechte naad stalen buizen en lage frequentie gelaste [...]
Oxidatie betekent dat wanneer staal wordt verhit, het wordt geoxideerd tot ijzeroxidehuid door de inwerking van CO2, H2O en O2 in het ovengas. Ongeveer 0,5%-3% van het staal wordt bij elke verhitting geoxideerd tot ijzeroxideschilfers (dat is verbrandingsverlies), waardoor het rendement daalt. Bij [...]
