Carbon Steel Rectangular Pipe

Carbon Steel Rectangular Pipe Manufacturer, Supplier in India

Carbon Steel Rectangular Pipe is a hollow, long-shaped tube made from carbon steel, a widely used alloy known for its strength and durability. This specific shape of the pipe, characterized by its rectangular cross-section, offers unique advantages in various applications. The primary applications of carbon steel rectangular pipe include construction and infrastructure projects, such as building frames, bridges, and highway barriers. It is also utilized in manufacturing furniture, automotive components, machinery, and equipment. The rectangular shape provides structural stability, making it suitable for load-bearing purposes, while the inherent strength of carbon steel ensures its ability to withstand heavy loads and external forces. Moreover, carbon steel rectangular pipes can be easily welded, allowing for efficient and cost-effective fabrication in different industries.

How is carbon steel rectangular pipe manufactured, and what are the common sizes and specifications available?

Carbon Steel Rectangular Pipes are manufactured through a process known as welded or seamless production, depending on the desired characteristics and application requirements. In the welded manufacturing process, flat carbon steel sheets are formed into a rectangular shape and then welded along the edges to create a continuous pipe. On the other hand, seamless manufacturing involves the extrusion of a solid carbon steel billet to form a seamless tube, which is subsequently shaped into a rectangular configuration.

Common sizes of carbon steel rectangular pipes vary depending on industry standards and specific project needs. However, some typical dimensions include widths ranging from 10mm to 500mm and heights ranging from 20mm to 300mm. The thickness or wall thickness can also vary, ranging from 1mm to 20mm. These dimensions may be subject to regional or international standards such as ASTM, DIN, or JIS, which provide specifications for tolerances, material grades, and mechanical properties. It is important to consult the appropriate standards or communicate with manufacturers to determine the precise sizes and specifications that meet the intended application requirements.

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 stainless 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 ss 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.
