Welded steel pipe DN500 standard ASTM A106/ASTM A53

Welded steel pipe DN500  is used a lot in simple projects because of its low cost. The identifying feature of welded pipe steel is that it has a weld seam that connects the tree along the tree or twisted the whole tree, which is often used in the simple construction industry.

Welded steel pipe DN500 As one of the products in the steel pipe group, welded steel pipe is the name to distinguish it from cast steel pipe and galvanized steel pipe. This is one of the popular materials used to make drainage pipes, used in the design of cars, bicycles, motorbikes, or used in construction and interior design. With such advantages, welded steel pipes are also manufactured with many different types to suit the needs of each project and field of construction and chemical industries.

Welded steel pipe DN500  has a hollow structure inside, the wall thickness is thin or not too thick, but the advantage is that it has a good bearing capacity. Depending on the size of the pipe, welded pipes are applied in different projects, for small or moderate sized steel pipe products, they will be applied in civil works, prefabricated houses, trusses. Churches, lighting poles, traffic light poles….

Welded steel pipe is generally divided into two types of 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.

Production standard of welded steel pipe DN500

Standard: ASTM A106 Grade B, ASTM A53-Grade B, API 5L, GOST, JIS, DIN, GB/T, ANSI, EN

Application: DN 550 steel pipe is used for oil and gas pipelines, for construction, pressure boilers, and for manufacturing hooks.

Welded steel pipe production process

Steel is refined through a complex manufacturing process of welded steel pipes requiring high technique and technology, then the raw materials are cast into ingots. Then the billet continues to melt to form welded steel pipe products. welded steel pipe has a long cylinder, the size of welded steel pipe varies depending on the purpose of use.

– Round welded steel pipe is manufactured on modern technological lines, according to the standards of ASTM A106, A53, X52, X42, A213-T91, A213-T22, A213-T23, A210-C,,,  API-5L, GOST , JIS , DIN , ANSI , EN . With sizes from phi 10 to phi 610 (Ø10 -> Ø610). Standard steel pipe length 6m or 12m (imported steel pipe).

– In welded steel pipes, there are many types to adapt to diverse needs of users: alloy cast welded steel pipe, carbon cast welded steel pipe, straight welded steel pipe, spiral welded steel pipe, galvanized welded steel pipe , black welded steel pipe.

Advantages of DN500 . welded steel pipe

Welded steel pipes have the advantage of high strength, many diameters suitable for different projects. 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: is a type of steel pipe used in mechanical engineering, processing to produce tables and chairs, machine details… This type of steel pipe requires a certain toughness to be able to process bending. bend or crush…

Easy to install, easy to use: Welded steel pipes are manufactured in many different specifications and thicknesses, and the thread, weld, and flange are easy to adjust according to requirements, 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.

Application of DN500 . welded steel pipe

Technical use: Welded steel pipes are used in welded steel frames that are subjected to loads from different directions. In construction, scaffolding made of metal always meets industry standards. Because there is no need to nail or install screws, assembly and dismantling time is quick and easy. Steel scaffolding can withstand large weight and is safe for users.

Used in automobile production: Currently on the street, the number of cars is increasing day by day, automobile manufacturing enterprises. There are many parts on the car that need to use steel pipes, including black pipe, stainless steel, stainless steel, galvanized steel …

Producing everyday items: Welded steel pipe is used as a cabinet frame, a bed, a knife handle, a kitchen utensil handle, a pan handle, 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, irrigation. …..
