♦ Difference
The black annealed pipe is a relatively common type of steel pipe, and it is also a type of steel pipe with a thin annealed density. Its physical properties are soft, and it can achieve the effect of not cracking and flaring. Galvanized steel pipe is the reprocessing of welded steel pipe, which is made into galvanized steel pipe by hot-dip galvanizing of welded steel pipe. For water supply, it is mainly galvanized pipes used. It is actually a steel pipe with a zinc coating. Adding zinc makes pipes more durable and also increases resistance to corrosion. Galvanized pipes have a property where the zinc starts to flake off after a while. That’s why it’s not suitable for carrying gas, as this zinc causes pipe chokes. It is very durable and lasts for over 40 years, which is why it is widely used as railings, scaffolding and all other construction projects.
