Is the steel pipe flexible or rigid
Release time:
2025-04-25
As flexible pipes, steel pipes are often used in scenarios that need to adapt to geological changes, such as crossing settlement areas or seismic zones.
Steel pipes are flexible pipes, and their classification is mainly based on industry standards and actual engineering characteristics:
Specification Definition
According to the "Construction and Acceptance Specifications for Water Supply and Drainage Pipe Engineering" (GB 50268-2008), flexible pipelines will undergo significant deformation under external loads, and their stability depends on the joint action of the pipe and surrounding soil, while rigid pipelines mainly rely on the strength of the material to resist deformation.
Comparison of Engineering Characteristics
Rigid pipelines (such as reinforced concrete pipes)
The deformation is extremely small and sensitive to foundation settlement. The failure mode is the rupture of the pipe wall.
Flexible Pipes (such as steel pipes, ductile iron pipes)
It can disperse loads through deformation and adapt to foundation settlement. The failure mode is mostly excessive deformation rather than rupture.
Application Scenarios
As flexible pipes, steel pipes are often used in scenarios that need to adapt to geological changes, such as crossing settlement areas or seismic zones.

Steel plates are alloyed products of iron, and they meet the needs of different industrial scenarios through composition and process optimization. If corrosion-resistant or high-strength materials are required, stainless steel plates or special steel plates are more suitable; pure iron is mostly used in laboratories or special electromagnetic fields.

Is the steel structure the main structure?
The core function of the main structure is to transfer loads and ensure overall safety. If the steel structure is only used for decoration or local reinforcement (such as adding a mezzanine), it does not have the function of the main structure.

Raw material composition: Molten iron is the main raw material, supplemented by scrap steel, slag-making materials (lime, fluorite, etc.) and deoxidizers (ferrosilicon, ferromanganese, etc.).

Is carbon steel plate a cold rolled plate?
The specific production process of the cold-rolled plate includes multiple rolling and annealing treatments at room temperature to obtain steel plates with a thickness of less than 4 mm. This process not only improves the surface quality and dimensional accuracy of the steel plate, but also gives it good mechanical properties and machining properties. Therefore, there are obvious differences in production process and performance between cold-rolled plates and carbon steel plates.

The coiled steel will be inspected, cut (sliced to specified sizes) and packaged, and will eventually become a finished product for easy storage and transportation.

Difference Between Rebar and Steel Rod
The choice of rebars or steel bars should be based on project requirements. Rebars are suitable for concrete reinforcement, while steel bars are used for large steel structures that require higher bearing capacity. For more information about specific models (such as 20MnSi rebars or SNCM220 round steel), please refer to relevant standards or manufacturer data.
