Product Advantage
1.Easily corroded
Although the oxide layer on the surface of black steel pipes can prevent corrosion, it is particularly susceptible to corrosion if it is exposed to moisture or corrosive chemicals, putting water and gas pipelines at risk of leakage and contamination. Therefore, black steel pipes must be regularly maintained and anti-corrosion measures taken during use.
2.Weight
Black steel pipes tend to be heavier than other materials such as PVC or aluminum, which makes handling and installation time-consuming and laborious. Due to the excessive weight, black steel pipes also need to pay additional support costs.
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 steel pipes are commonly used for gas lines, water supply, and fire sprinklers. Proper inspection ensures safety and longevity.
Packing &Shipping
Steel pipes must be screened and inspected before transportation. The surface of the black steel tubes should be inspected for pits, dents, or other surface damage using adequate lighting and a magnifying glass that increases detail. If steel pipe is found to be bent or deformed, it should be marked to avoid careless use.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.
