EN 10025 Carbon Steel Seamless Pipe Manufacturer, Supplier in India

EN 10025 Steel Pipe refers to a set of European standards specifying the structural steel pipes' technical delivery conditions. It is widely used in various industries for structural applications due to its excellent mechanical properties and durability. EN 10025 steel pipes are known for their high strength, which allows them to withstand heavy loads and provide structural integrity.

These pipes exhibit good weldability, enabling ease of fabrication and installation. Additionally, EN 10025 steel pipes offer excellent resistance to corrosion, making them suitable for indoor and outdoor applications. They are available in different grades, each with specific characteristics to meet diverse structural requirements. Overall, EN 10025 steel pipe is valued for its strength, durability, weldability, and corrosion resistance, making it a reliable choice for various structural applications.

What are the standard specifications and dimensions for EN 10025 steel pipe?

The standard specifications and dimensions for EN 10025 steel pipe are outlined in the European standard EN 10025-2:2004. This standard provides guidelines for the technical delivery conditions of non-alloy structural steels, including steel pipes. EN 10025-2 specifies various steel grades, such as S235, S275, S355, and S450, each denoting different yield strengths and impacting properties. The dimensions of EN 10025 steel pipe vary depending on the specific grade and application requirements.

Commonly, the pipe sizes range from small (e.g., 21.3mm) to larger (e.g., 508mm), with corresponding wall thicknesses that meet specific structural demands. The standard also provides details on tolerances, chemical composition, mechanical properties, and other relevant factors to ensure the quality and performance of EN 10025 steel pipe. These specifications and dimensions are essential guidelines for manufacturers, engineers, and users in selecting and utilizing EN 10025 steel pipe for their structural projects.

Rolling and welding

Firstly, the carbon steel strips are made to gone through various quality checks and are trimmed at edges. They are then fed to the tubes mill by carbon steel pipe manufacturers in India. The strips pass through the number of rollers as per the required size. In the tubes-mill, the strip is gradually converted into the tubular shape. The fitted welding machine is then used to weld trim edges of the strip using TIG welding process. The scraps and inside weld bead are removed instantaneously by the Tibo machine. In this way, rolled pipes and tubes are formed.

The cleaning and heating phase

The rolled carbon steel seamless pipes thus manufactured are cut to the required lengths depending upon the industrial demand. These stainless pipes and tubes are then subjected to cleaning to remove the dirt. Further, a heat treatment is given to these rolled pipes and tubes to remove the stresses that may occur due to welding and formation processes. Heat treatment is given on the continuously rolling hearth furnace. The furnace is fitted with temperature recorders and controllers. After the heat treatment process, the SS tubes and pipes are straightened and subjected to pickling for removing scales from the surface.

Cold- drawing process

In some cases, the required size may not be obtained from the mill directly. Then, the cold operation process can be used to obtain the desired size. In cold drawing process, the tubes or pipes are coated with oxalic and soap solution. This solution acts as a lubricant to reduce friction while cold drawing operation. In the cold drawing process, the tube or pipe is drawn over the bench using Die plugs.

Finishing process

The drawn-out tube or carbon steel pipe is then subjected to cleaning, heat treatment, pickling and straightening. The computerized ink jet marking machine is used to do the marking on the finished pipes or tubes. The pipe or tube is marked with grade of material, size, heat number and the stamp of third party inspection before passing on to carbon steel pipe exporters. The stainless tubes or pipes thus produced will undergo certain testing and quality checks. This process is followed by proper packing and dispatch. There are numerous numbers of carbon steel pipe applications, these pipes and tubes are used thereafter for.
