Short Description:

Stainless steel square tube

Rectangular tube is a name for square coffin and rectangular coffin, that is, steel tubes with equal and unequal side lengths. It is made of strip steel after process treatment. Generally, the strip steel is unpacked, flattened, crimped, and welded to form a round tube, and then the round tube is rolled into a square tube and then cut to the required length.

Stainless steel rectangular tube is a kind of hollow long strip of steel with a rectangular section, so it is called a rectangular tube.

Main Application

Stainless steel square tubes are widely used in construction, manufacturing, transportation and other industries. Due to its strength, durability, and corrosion resistance, stainless steel square tubing is often used in challenging environments where other materials cannot.

One of the most common applications for stainless steel square tubes is construction. They are often used to make strong and durable frames for buildings, bridges and other structures. Stainless steel square tubing can withstand heavy loads and resist corrosion caused by weather and environmental elements, making it ideal for these applications.

Stainless steel square tubes are also commonly used in manufacturing. They can be made in a variety of shapes and sizes, making them ideal for making machinery, equipment and industrial parts. Stainless steel square tubes are commonly used in the manufacture of conveyor systems, automotive components and kitchen equipment, among many other products.

Another application of stainless steel square tube is transportation. They are used to build structures for airplanes, ships and other vehicles. Stainless steel square tubes are light in weight yet high in strength, making them ideal for transportation related applications where weight is important.

Stainless steel square tubes are also used in the food and beverage industry. They are used in the manufacture of equipment, such as stainless steel tubes, pipes, and storage tanks, for the transport and storage of various fluids and products. Stainless steel square tubes are easy to clean, which is essential in the food industry where hygiene is a top priority.

Process of Production

The production process of stainless steel pipe needs to go through: stapling → calendering → annealing → slicing → pipe making → polishing
1. Tape booking: Prepare raw materials of steel tape in advance according to demand
2. Calendering: Use calendering machine to press the roll plate like rolling noodles and roll the roll plate to the required thickness.
3, annealing: due to the rolling plate after calendering, physical properties can not reach the standard, toughness is not enough, need to annealing, restore stainless steel properties.
4. Strip: According to the outer diameter of the pipe produced, strip it
5. Pipe making: Put the divided steel strip into the pipe making machine with different pipe diameter molds for production, roll it into the corresponding shape, and then weld it
6. Polishing: After the pipe is formed, the surface is polished by the polishing machine.
