Welded steel pipe DN300

Welded steel pipe DN300 has a hollow structure inside, and the wall thickness is thin or not too thick, but the advantage is that the bearing capacity is also quite good. Depending on the size of the pipe, welded pipes are applied in different projects, for small or medium-sized pipe products, they will be applied in civil works, prefabricated houses, and trusses. teachers, lighting poles, traffic light poles….

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.
