Management of the weight table Rectangular Pipe Rectangular process characteristics

Like other steel pipe materials, the production of rectangular steel pipes is also based on national standards or industry standards, so width, height and wall thickness are generally some common sizes. Rectangular square tube refers to a hollow metal section with a rectangular or square cross-section. It is used in construction, machinery manufacturing, shipbuilding, hardware, steel structure engineering and other industries. Based on the common market, rectangular steel tube specifications, someone produced a rectangular table-side management on weight and rectangular steel pipe technology features. Xiao Bian gave you an introduction here.

Rectangular steel pipe theoretical weight calculation

According to the principle of weight = density x volume, the formula for rectangular steel pipe is as follows:

Theoretical weight (kg/m) = (width + height) * 2 * wall thickness * 0.00785, where width, height, and wall thickness are in units of homme.

For example, for a 100*80*4 rectangular square tube, the weight per meter is (100+80)*2*4*0.00785=11.304KG.

Rectangular steel pipe technology requirements

1 Rectangular straight pipe must be made on the dedicated inlet line to ensure the accuracy of the air duct and the tightness of the air duct.

2 The blank feeding of the rectangular duct fittings should be fully automated using computer software on imported special machines, and the automatic plasma cutting process should be completed on the imported sheet metal special plasma cutting machine.

3 The mouthpiece connection of the rectangular air duct should adopt the imported automatic articulator for the bite joint process.

4 The connection between the rectangular air duct body and the plug flange shall be made using rivetless connection technology and the imported equipment shall be used for the rivetless connection process.

5 The connection flange of the rectangular air duct should be connected with the connecting flange and the plug flange. When the length of the large side of the air duct is less than or equal to 2000mm, the common flange connection mode should be adopted. The long side length of the air duct is greater than 2000mm When the sum is less than or equal to 2500mm, the form of the plug-in flange should be used. The rectangular duct should be mechanically pressed to strengthen the ribs. The spacing between stiffeners is about 300mm.

Rectangular steel pipe process features

(1) Advanced technology: The use of world-class numerical control equipment for pipe management, computer software programming, just enter the relevant data of the wind pipe shape, after a few seconds will be able to automatically generate the shape of the parts, the composition of the number and data connection to the plasma cutting The machine automatically feeds.

Software programming, automatic cutting duct has the following advantages:

The form of hurricane pipes is diversified. Complete specifications, this brings convenience to the design choice, to meet the needs of different HVAC engineering systems.

⊕ Good interchangeability: accurate dimensions, standard pipe fittings, easy replacement. The appearance and inner wall of the bowl are smooth and smooth. From the standpoint of the appearance of the product, the appearance is smooth and beautiful. From the standpoint of the performance of the air duct, the air duct has a small wind resistance due to its smooth inner wall and streamline shape.

Summary: The relevant information about the rectangular management theory weight table and the rectangular steel pipe process features was introduced here for everyone. I hope this article will be helpful to everyone. If you still have something you don't understand, you can leave a message to Xiaobian at the bottom.
