Square tubes and rectangular tubes,
Rectangular and Square tubes are manufactured using the finest quality steel tubes,
Square and rectangular tubes are widely used in welded steel frames,
which are subjected to loads from multiple directions.
Tubing profiles are suitable for multi-axle loading having uniform geometry along with two or more transverse axes.
This enhances the uniform strength of these tubes, making them a better choice for poles.
It is manufactured by a process of slowly changing the shape of the flat steel plate to achieve roundness as the edges are submitted for welding.
Next, the edges are welded together to form the main tube, and this main tube passes through,
Also referred to as a mother tube, a series of forming holders form the final square or rectangular shape.
Longitudinally welded rectangular tubes are manufactured from black sheet in different sizes from 0.80 mm to 7.11 mm thickness.
The main differences between square tubes and rectangular tubes
The cross section of the square tube differs, as it is square, while the cross section of the rectangular tube is rectangular.
Various uses of square tubes and rectangular tubes:
Square tubes are used in many purposes in construction, machinery manufacturing,
steel construction projects, shipbuilding, solar arches, steel structure engineering,
Also power engineering, power plants, agricultural and chemical machinery, glass walls, automobile chassis, airports,
Boiler construction, highway guardrail, building construction, pressure vessels, oil storage tanks, bridges, power station equipment.
As for rectangular tubes, a large number of them are used to transport liquids, such as petroleum, natural gas, water, gas, steam, etc.
In addition, when the bending and torsional strength are the same, the weight is light, so it is widely used in the manufacture of mechanical parts, engineering structure.
It is also used to produce a variety of conventional weapons, barrels, and shells, and soon.
The coverage range of square tube, which is a variant of rectangular tube, varies.
There are two main methods for producing rectangular tubes, namely cold rolling and hot rolling.
The rectangular tube is also hot-rolled by rolling the hot-rolled strip.
As for cold drawn or cold rolled precision tube, cold rolled tube is cold drawn or cold rolled precision tube of mechanical structure,
The equipment is hydraulic with high dimensional accuracy and good surface finish.
Also, many defects in square tube occur in the hole, so blank tube punching is a basic procedure for square tube production.
The main difficulty of high ingot holes is the low punching performance.
In order to ensure quality, it is necessary to logically determine the deformation parameters of the perforation.
