Product Advantage
1. Uniformity
It provides regularity in size, shape, and tolerances, making it a popular choice for original equipment manufacturer (OEM) applications.
2. Low cost
Compared to other types of mechanical pipes, square pipes require less process. Therefore, it can reduce the cost of low budget items.
3. Create Metal Structure
You can easily bend, punch or drill a square tubing to bind it to itself or any other material. These characteristics of square pipes make it very easy to build metal structures.
APPLICATION
Black pipe, looks black from appearance. The dark color comes from the iron-oxide formed on its surface during manufacturing. Black steel pipe refers to ordinary iron pipe and are mainly used for gas lines, it is also used to connect appliances to their supply lines. It is the pipe that is used by businesses and residential homes to convey their supply of natural or propane gas.
Black steel pipe is also used for fire sprinkler systems because of its strong resistance to heat. It is usually joined by welding or by using mechanical couplings. It can even be used instead of galvanized pipe in projects other than carrying water for drinking.
Black iron pipe is actually made of a low-grade "mild steel" compound. This gives it much better corrosion resistance than traditional cast iron piping. There are few standards that all black iron pipes adhere to. However, they are all made to handle natural and propane gas, which usually stay below 60psi. The standards that black iron pipe must conform to guarantee a pressure rating of at least 150psi, if installed properly.
Packing &Shipping
Packaging black steel pipe
Black pipes should be grouped before being loaded into packaging materials. The tied combination can relieve the pressure caused by friction and collision, and can also prevent the steel pipe from rolling or moving during transportation. After that, place the steel pipe and foam board in the center of the card, fold the card in half so that only the folds on the surface of the steel pipe can be touched by hand, and finally fix it. This can ensure that the steel pipe will not separate from the card during transportation, or cause deformation and damage due to fluctuations.
