Product Advantage
1. Uniformity
It provides regularity in size, shape, and tolerances, making it a popular choice for original equipment manufacturer (OEM) applications.
2. Strength
square tubings have high tensile strength and are therefore extremely resistant to extreme temperatures and pressures.
3. Low cost
Compared to other types of mechanical pipes, square pipes require less process. Therefore, it can reduce the cost of low budget items.
APPLICATION
Black steel pipes are commonly used for gas lines, water supply, and fire sprinklers. Proper inspection ensures safety and longevity.
Packing &Shipping
Black steel pipe is a common building material, playing an important role in construction, manufacturing and other fields. If you need to transport steel pipes, safe, stable and reliable transportation is essential.
1. Transportation preparation
Before loading the black metal pipes into the packaging materials, some necessary preparations should be done to reduce the risk of damage during transportation.
2. Screening and inspection
The steel pipes must be screened and inspected before transportation. Adequate lighting and a magnifying glass should be used to check whether there are pits, dents or other surface damage on the surface of the black steel pipes. If the steel pipe is found to be bent or deformed, it should be marked to avoid misuse. At the same time, check the size and shape of the steel pipes to ensure that they fit tightly to prevent friction and damage caused by movement between the steel pipes.
