Black structural pipe

1. What is black structural pipe?

Black structural pipe refers to a structural pipe with a black oxide layer on its surface. The dark color comes from the iron oxide formed on its surface during the manufacturing process. When a steel pipe is forged, black oxide scale forms on its surface.

Structural pipe is a professional pipe used in building structures. It is mainly used for the support, connection and reinforcement of building structural structures. It is made of high-strength steel and has high load-bearing capacity and earthquake resistance, ensuring the safety and stability of the building.

Black structural welded steel pipes are used in steel structures, bridge supports, building structure pipes, pile foundation pipes, etc. Generally, the greater the pressure-bearing and pressure-resistant capabilities required for structural pipes, the thicker the wall thickness used. The main material of structural pipes is carbon steel, which has the characteristics of high strength and durability. The main parameters of structural welded steel pipes include diameter, wall thickness, length, welding technology, whether surface anti-corrosion and heat preservation treatment is required, etc.

2. The difference between black structural pipes and fluid pipes

The main differences between black steel structural pipes and fluid pipes are design uses, materials, manufacturing processes and performance. The following is a detailed introduction:

(1) Design purpose

Structural pipes are mainly used for structural support in construction projects and bear static loads to ensure the stability and safety of buildings; fluid pipes are mainly used to transport fluids such as gases and liquids and bear dynamic loads.

(2)Material

Black structural pipes generally use materials such as steel pipes and concrete pipes. The manufacturing process is relatively simple and can be fixed by welding, riveting, crimping, etc.; fluid pipes need to consider the transportation of fluids, and are generally made of plastic pipes, glass fiber reinforced plastic pipes and other materials. At the same time, Consider factors such as the internal smoothness of the pipe and the tightness of the pipe connection.

(3)Manufacturing process

The manufacturing processes of structural pipes and fluid pipes are also different. Structural pipes are mainly produced through welding, hot rolling and other processes, while fluid pipes need to go through multiple processing processes, such as pickling, oil immersion, cold drawing, annealing and other procedures. Ensure the surface finish and internal quality of the pipe.

(4)Performance

Structural pipes have higher cost requirements and need to have good pressure-bearing capacity; fluid pipes require good sealing performance.

3. How to choose black steel structural pipe?

When selecting structural pipe, there are several key factors to consider.

(1)Material

Materials commonly used for structural pipes include iron, steel aluminum alloy, polyvinyl chloride (PVC), etc. Different materials have different properties and benefits, so selections need to be weighed against specific needs.

(2)Easy to maintain and install

Structural duct systems should be easy to install and maintain, which reduces labor and time costs. Additionally, ductwork system scalability and flexibility should be considered to accommodate future needs.

(3)Life span

Quality structural pipe materials and workmanship ensure the longevity and safety of your piping system. Therefore, when choosing a black steel structural supplier, you should choose a reliable partner and comply with relevant safety standards and regulations.
