Welded steel DN300 is generally divided into two types straight welded black pipe and spiral welded black pipe. Using spiral coil technology and high-frequency welding to create the most durable steel pipe products.
Advantages of Welded steel pipe DN300
Welded steel DN300 has the advantage of high durability, and has many diameters suitable for each different project. At the same time, the price of the products is relatively cheap, so it will reduce the construction costs for the contractor.
Welded steel pipes are also divided into many types to suit each project, such as:
–Industrial pipes: A type of pipe frequently used in construction works, pipes used to conduct oil and gas according to API standards, the technical standards of this steel pipe product are SS400, S540, STK400
–Fabricated steel pipe: a type of steel pipe used in mechanical engineering, processing to produce tables and chairs, machine details…This type of steel pipe requires certain toughness to be able to bend processing. or crush…
Easy to install, easy to use: Welded steel pipe DN300 is produced with many different specifications and thicknesses and the thread, weld, and flange are easy to adjust as required, so this type of steel pipe is very flexible in use.
The process of installing black steel pipes is not too complicated, but also very easy when moving and installing at construction sites. Therefore, depending on each project, customers can use round steel pipes of different lengths for threading or flange connection.

Technical use: DN300 welded steel pipe is used in welded steel frames that are subjected to loads from different directions. In construction, scaffolding made of the metal always meets industry standards. Because there is no need to nail or install screws, assembly and dismantling times are quick and easy. Steel scaffolding can withstand large weights and is safe for users.
Used in automobile production: Currently on the street, the number of cars is increasing day by day, in automobile manufacturing enterprises. There are many parts of the car that need to use steel pipes, including black pipe, stainless steel, stainless steel, and galvanized steel …
Producing everyday items: Welded steel pipe is used as a cabinet frame, a bed, a knife handle, a kitchen utensil handle, a panhandle, etc.
Based on the above classifications, we can also know that steel pipe is not only used in the construction industry, but also in furniture manufacturing, machine building, automobile manufacturing, ships, and irrigation. …..
