A fire fighting system must ensure continuous water supply, stable water pressure, and immediate response capability. Any leakage, pipe failure, or pressure drop may cause significant safety risks. Ductile iron pipe provides the reliability and strength required to support these mission-critical conditions. Key Advantages of Ductile Iron Pipe for Fire Fighting Systems High Pressure Resistance Fire fighting networks often operate under high water pressure, particularly in high-rise buildings, municipal fire mains, and industrial fire protection loops. Ductile iron pipe demonstrates stable performance under both normal and surge pressure, ensuring consistent flow delivery during fire emergencies.

DI jacking pipe possess high strength, so it can bear large jacking force. During pipeline construction, the advantages of non-excavation, no destroy on surface buildings and no impact on traffic, enable the pipes to be used in almost any climate and environment. Such kind of pipe can meet the requirements of saving operation time, higher efficiency, high safety and low cost. Application Field: Jacking pipes are applied when the pipeline is needed to cross obstructions such as roads, railways, rivers and buildings, while trench excavation is not allowed or difficult to prepare on the construction site. Jacking pipe adopts T-type flexible joint. It features sound sealing performance, faster installation, more reliable internal and external anti-corrosion coating, and is adaptive to various soil environments and different transmitted media.

Ductile iron pipe is a type of cast-iron pipe made by adding magnesium to molten iron, which changes the graphite structure from flakes to spheroids. This transformation gives the pipe a much higher tensile strength, impact resistance, and flexibility compared to traditional gray cast iron pipes. 1.The standard of pipe: ISO 2531, EN545 , EN598. 2. Pipe class: K9, C40, C30, C25, etc. 3. Pipe joint: push-on joint(Tyton joint), , self-restrained joint 4.

The non-rotating wire rope is safe to use, reliable, and evenly stressed. It runs smoothly and is not prone to wire breakage. Even if the wire is broken, it will not be uplifted. It will still lie in the original position, so that it will not scratch the rope wheel or drum, and will not affect others. The normal work of the steel wire is safe, reliable, and the force is even. It is not easy to break the wire when it runs smoothly. Why use the multi-strand non-rotating steel wire rope to name: Let’s take a look at the working principle of the non-rotating steel wire rope. The inner and outer layers are twisted in opposite directions. When the outer layer is subjected to a force in the opposite direction, since the inner and outer strands have opposite twist directions, the rotation of the outer strands will be restricted. This will appropriately reduce the angle of rotation of the load-bearing object in the air, but when the free end of the wire rope rotates in the opposite direction to the twisting direction of the outer strands, the inner rope will be tightened, which will shorten the inner strands and shorten the outer strands. Extend, but because both ends of the rope head have been tightened, the outer strands will be forced to bulge, causing the inner and outer strands to separate. If the separation is severe, the structure of the wire rope will be damaged, causing the load to concentrate on the inner strands and reducing the safety factor of the wire rope. , The service life will be greatly reduced.

Stainless steel wire rope has many characteristics such as high temperature resistance, good fatigue resistance, excellent breaking force, long service life, and durability. It is widely used in coal, petroleum, metallurgy, chemical industry, ships, bridges, electric power, rubber, military industry, tourism, and water conservancy. , Light industry and other industries, products can be produced in accordance with international and foreign advanced standards such as ISO, BS, DIN, JIS, ABS, LR, etc. The following is about Stainless Aircraft Cable related, I hope to help you better understand Stainless Aircraft Cable. 1. In the equipment reform of the chemical, fertilizer, chemical fiber and other industries, stainless steel wire ropes are used in the deployment of their updated equipment. 2. The widely used stainless steel welding rod and a large number of stainless steel components, springs, abutting parts, etc., all use stainless steel wire rope.
