Types of steel pipes D40
With size D40, we see that there will be many popular types of steel pipes below:
Galvanized steel pipes D40
This type of steel pipe is produced from black steel pipes. Then hot-dip galvanized. The outer zinc layer helps protect steel pipes from environmental corrosion. Thanks to increased endurance and durability, D40 hot-dip galvanized steel pipes have a long lifespan.
Black steel pipe
Black steel pipes (D40) are not galvanized. It has a high bearing capacity. However, because there is no outer protective layer, it is susceptible to corrosion. This is also the reason it is recommended for use in indoor projects or places with stable, not-too-harsh weather conditions.
Electrolytic galvanized steel pipes
This type of pipe has a production process similar to hot-dip galvanized steel pipes. However, instead of going through a hot-dip zinc process, it will be electrolytically galvanized. The outer zinc layer has a thinner thickness than the hot-dip galvanizing method. Therefore, the corrosion resistance is also worse than that of hot-dip galvanized pipes.
Seamless steel pipes
D40 seamless steel pipes are cast from monolithic steel. It has a solid structure, so it is sturdy and has a high bearing capacity. At the same time, the pressure resistance and durability are also great.
Welded steel pipes
With a diameter of D40, this steel pipe is produced by the welding method. This type of pipe has a hollow structure, a lower bearing capacity, and a lower corrosion resistance than cast pipes. Therefore, processing welded steel pipes is also easier and faster. This is also the reason why the price of welded pipes is always cheaper than seamless steel pipes.
How much does the D40 steel pipe cost? Is it expensive?
According to what Bao Tin Steel has learned, currently, the price of D40 steel pipe is in the range of 17,000 VND/kg to 25,000 VND/kg.
