a. The deoxidation method is designated as follows: | ||||||||
FF: Fully killed steel containing nitrogen binding elements in amounts sufficient to bind available nitrogen (e.g. min. 0,020 % total Al or 0,015 % soluble Al). | ||||||||
b. The maximum value for nitrogen does not apply if the chemical composition shows a minimum total Al content of 0,020 % with a minimum Al/N ratio of 2:1, or if sufficient other N-binding elements are present. The N-binding elements shall be recorded in the Inspection Document. |
Product description
Our fire protection pipes are made using a meticulous process that continuously bends high-quality steel strips into a spiral shape and then precision welds the spiral seams. This innovative manufacturing technique produces long, continuous pipes that are not only strong and durable, but also extremely reliable for a variety of applications. Whether you need to transport liquids, gases or solid materials, our pipes are carefully designed to withstand the rigors of harsh environments, ensuring safety and performance.
In addition to their primary function of fluid and material transfer, our spiral welded pipes are also ideal for structural and industrial applications. Their versatility makes them a top choice for construction projects, fire safety systems, and other critical infrastructure needs.
When it comes to safety, our reliable fire pipe line are the trusted solution. We understand the importance of building reliable systems, especially in high-risk environments. That’s why we prioritize quality and reliability in every product we manufacture.
Product Advantage
1. Firstly, their durability ensures they can withstand extreme conditions, giving you peace of mind in critical situations.
2. The spiral design increases the strength of the pipe, allowing for efficient flow and reducing the risk of leaks. This is especially important in fire safety applications where every second counts.
3. Our commitment to quality means our fire protection piping meets strict industry standards, ensuring compliance and reliability. By choosing our products, you are not only investing in safety, but also in solutions that improve operational efficiency.
Product shortcoming
1. A significant disadvantage is the initial installation cost, which may be higher than alternative materials.
2. The welding process, while ensuring durability, can introduce weaknesses if not done properly.
3.Regular maintenance is also necessary to prevent corrosion and ensure longevity, which can increase overall operating costs.
