S355 JR Spiral Steel Pipe For Sewer Line

S355 JR Spiral Steel Pipe Strength and Versatility

 S355 JR spiral steel pipe is manufactured using advanced technology and high-quality steel to combine strength and versatility in a single product. These pipes are designed to withstand extreme pressures, making them suitable for a wide range of applications. Whether used to transport water, oil or natural gas, these pipes offer impeccable performance and durability.

Strong structure and structural integrity

 One of the most notable features of S355 JR spiral steel pipe is its sturdy construction, which ensures structural integrity. These pipes feature spiral seams that ensure maximum strength while minimizing the risk of leakage or failure. This advanced design enables the pipeline to withstand heavy loads and harsh weather conditions, making it ideal for critical infrastructure such as bridges, tunnels and high-rise buildings.

Mechanical Property

Chemical Composition

Hydrostatic Test

Each length of pipe shall be tested by the manufacturer to a hydrostatic pressure that will produce in the pipe wall a stress of not less than 60% of the specified minimum yield strength at room temperature. The pressure shall be determined by the following equation:
P=2St/D

Permissible Variations In Weights and Dimensions

Each length of pipe shall be weighed separately and its weight shall not vary more than 10% over or 5.5% under its theoretical weight, calculated using its length and its weight per unit length
The outside diameter shall not vary more than ±1% from the specified nominal outside diameter
Wall thickness at any point shall not more than 12.5% under the specified wall thickness

Resistant to corrosion and environmental factors

 In any construction project, the longevity and reliability of materials are crucial.  S355 JR spiral steel pipes excel in this regard as they are highly resistant to corrosion and environmental factors. The steel used in production is specially treated to increase its resistance, making these pipes suitable for both above- and below-ground installations. This resistance not only ensures the integrity of the pipeline, but also significantly reduces maintenance costs, making it a cost-effective option.

Increase sustainability and eco-friendliness

 Faced with global concerns about climate change and environmental impacts, the construction industry is actively seeking sustainable solutions.  S355 JR spiral steel pipe is highly recyclable and contributes to this sustainable approach. These pipes can be reprocessed and reused, minimizing waste and conserving natural resources. Additionally, their long service life greatly reduces the need for replacement, further reducing their overall environmental footprint.

Adhere to strict quality standards

 S355 JR spiral steel pipe is carefully manufactured according to strict quality standards. This ensures that each pipe performs consistently and complies with required safety regulations. Whether it’s critical projects like oil and gas pipelines or transportation infrastructure, these pipelines provide reliability, trust and peace of mind to engineers, contractors and project owners.

In conclusion

 To sum up, S355 JR spiral steel pipe has become an integral part of modern infrastructure due to its superior strength, versatility and overall performance. Its sturdy construction, corrosion resistance and compliance with quality standards make it ideal for a variety of construction projects. Furthermore, their sustainability and eco-friendliness add value and contribute to a green future. As we continue to witness advancements in the construction industry, it is clear that S355 JR spiral steel pipe will continue to play a vital role in shaping the world we live in.
