Core advantages of ERW pipes
1. High strength and reliability
ERW pipe adopts high-frequency resistance welding process. The weld is directly fused by the base material and the stress is eliminated by online heat treatment. The strength of the weld is equivalent to that of the base material, and some performance is even better than that of seamless steel pipe. Its precise molding process ensures uniform wall thickness of the pipe, and its outstanding resistance to pressure and deformation makes it suitable for load-bearing structures such as high-rise buildings and bridges.
2. Corrosion resistance and durability
The surface of ERW pipe is smooth and burr-free, which is convenient for painting and anti-corrosion treatment. Through galvanizing, plastic coating and other processes, the corrosion resistance can be significantly improved and the service life can be extended. Especially in humid environments or underground projects, the chemical corrosion resistance of ERW pipe is far superior to that of traditional pipes.
3. High precision and convenient construction
ERW pipes have high dimensional accuracy (wall thickness deviation ≤ ±0.2mm), no elliptical deformation of the pipe mouth, and are easy to quickly connect and install. The standardized interface design reduces on-site cutting, reduces construction losses, and improves efficiency by more than 30%. In construction, workers can connect pipes more easily and quickly, saving time and labor costs.
4. Economical and environmentally friendly
ERW pipes have low energy consumption in production, high yield rate, and comprehensive costs 15%-20% lower than seamless steel pipes. At the same time, their lightweight characteristics reduce transportation and hoisting costs, meeting the sustainable development needs of green buildings. Choosing ERW pipes can not only save money for the project, but also contribute to environmental protection.
Typical application scenarios in the construction field
1. Steel structure frame
When building large commercial complexes and sports stadiums, ERW pipes are often used to make load-bearing components such as beams, columns, and trusses. Moreover, ERW pipes have high straightness and a smooth surface. In some architectural designs that pursue a simple industrial style, they can be directly exposed as decorative structures.
2. Pipeline transportation system
Water supply and drainage pipelines: Whether it is a municipal water supply system or a sewage treatment plant drainage pipeline, the high pressure resistance and corrosion resistance of ERW pipes can ensure the stable operation of the pipelines.
HVAC ducts: The inner wall of ERW pipes is smooth, which can effectively reduce the resistance of the fluid in the pipes, reduce the energy consumption of the HVAC system during operation, and improve the overall energy efficiency of the system.
Fire sprinkler piping: In emergency situations such as fire, the proper functioning of the fire sprinkler system is critical.
3. Building Envelope
In modern buildings, curtain wall keels, canopy supports and other enclosure structures are often made of ERW pipes. ERW pipes have sufficient strength to support the weight of curtain walls and canopies, and can achieve beautiful effects through surface treatment, adapting to various complex architectural designs.
Conclusion
ERW pipes are reshaping the selection criteria for building materials with their comprehensive advantages in performance, cost and environmental protection. Whether as the main structural material or the core of the piping system, ERW pipes provide reliable support for the safety, efficiency and sustainability of modern buildings. In the future, with the continuous upgrading of process technology, ERW pipes will be more widely used in the construction field.
