What are the boxes and tubes of all kinds according to size?
Box steel is steel with a hollow structure, thin-walled, of light weight with box shape, which may be square, rectangular or round. Steel boxes and tubes are made of a mixture of steel and some carbon content to increase durability and bearing. In order to increase the durability and corrosion resistance of the steel layer, people often galvanized or poorly hot-dip steel tubes and boxes.
Like other steel products, canned steel possesses good qualities of steel materials such as high strength, high pressure resistance. Therefore, box steel is always the most ideal product for projects that require high pressure resistance.
Pipe steel usually has a thickness of 0.7 – 6.35mm, diameter ranges from 12.7mm to 219.1mm. The needs to use each project, each project as well as the requirements of each industry are often different. Therefore, to meet such diverse needs, steel boxes and tubes are divided into various types with different box sizes and sizes.
Types of boxes and steel pipes used in industry are quite diverse such as rectangular box steel, square box steel, spiral welded steel pipes, galvanized steel pipes, high-rise welded steel pipes, straight welded steel pipes, carbon cast steel pipes, etc. ..
Process of manufacturing boxes and steel pipes according to their sizes at Manh Ha Steel
Over the years, Vietnam has developed a strong and sustainable economy. This increases the number of scale works, projects, the demand for boxes and steel pipes is increasing. To meet the high demand for quality steel boxes and pipes, Manh Ha Steel is equipped with modern machinery systems, possessing the most advanced technology. The process of manufacturing boxes and steel pipes according to dimensions at Manh Ha Steel is a closed process, strictly controlled at each stage.
Specifically, the process of producing boxes and steel pipes at Manh Ha Steel includes the following steps:
Step 1: Select ingredients
This is the most important step in the process. Whether or not the quality of a box, steel pipe product depends largely on the selection of raw materials.
Crude steel is made by heating raw materials and adding alloys and removing impurities. Then, the molten steel material is transferred to continuous casting machine to make steel plates.
The steel plate is heated to a high temperature of up to 2,200 ° F, cleaning the rust layer with specialized equipment with high pressure. The steel is then hot rolled into thin, narrow strips of steel called skelp. Skelp is soaked with sulfuric acid, washed with water and rolled into large rolls as a raw material for making tubes.
Based on the width of the skelp, we can determine the diameter of the pipe that can be made. Before production, raw materials will be tested and tested to ensure the quality of boxes and steel pipes.
Step 2: Put raw materials into the band sawing machine
After checking, the material of steel pipe production is put into the modern banding machine. Sawn tape will be sorted and put into warehouse.
Step 3: Straighten the billet
Next, sawed tape is fed into the high-tech pipe mill line. The billet is rolled and stretched through grooved and stacked rollers to form seamless steel pipes.
Step 4: Shaping boxes, steel pipes
After straightening the billet, boxes, steel pipes are shaped, adjusted, welded in the shape of customers’ requirements such as square pipe, rectangular tube, round tube, elliptical tube ….
Step 5: Cut the box, steel pipe
After forming, the pipe is cooled and straightened through the machine. Based on customers’ required size, workers will cut boxes and steel pipes as required.
To increase the durability of boxes, steel pipes, workers dipped in the zinc tank for a while. Poor code protection helps protect the inner steel section, preventing external rusting without the use of paint.
Step 6: Handing over customers
Boxes, steel pipes are strapped, sorted, cooled and checked. Then, Manh Ha Steel packed and handed over to customers.
