The shield to protect safety-gray iron/ductile iron fire fighting equipment shell casting, tough and reliable, casts a life defense line.

The shield of fire line is cast in the heart-high performance gray iron/ductile iron fire equipment shell casting, escorting the life passage

 In the fire rescue against time, every second is about life and death.

What supports all this is not only the heroic firefighters, but also the obscure but vital core component behind it-the fire equipment shell.

We focus on building high-quality gray iron (HT250/HT300) and ductile iron (QT450-10, QT500-7, etc.) fire-fighting equipment shell castings, providing a solid and reliable "first line of defense" for the fire-fighting system with excellent material properties and precision casting technology. 

Why is gray iron/ductile iron the ideal choice for fire protection shell?

Gray Iron: 

It has excellent shock absorption, wear resistance and good casting fluidity, and is suitable for parts such as valve body, pump shell and interface shell which require high sealing and stability, effectively suppressing running noise and improving the silent performance of the system. 

Ductile Iron: 

The strength is close to that of steel, while retaining the casting advantages of cast iron.

It has high tensile strength, good toughness and impact resistance, and is especially suitable for key pressure-bearing parts such as high-pressure fire hydrants, hose joints, fire extinguishing system main shells, etc., and it is still rock-solid even under extreme temperature or sudden impact. 

Core advantage High strength & high sealability:

the dense structure ensures no leakage after long-term use and meets the strict standards of high-pressure fire protection system. 

Corrosion resistance & high temperature resistance:

After surface anti-rust treatment (such as phosphating, epoxy coating, etc.), it can adapt to various harsh environments such as humidity, salt spray and outdoor. 

Accurate size & high consistency: adopting resin sand/coated sand technology and strict process control to ensure strong interchangeability of batch products and worry-free assembly. 

Meet international certification: support fire protection industry standards such as UL, FM, CE, GB, and help customers quickly pass the whole machine certification. 

Widely used scenarios Indoor and outdoor fire hydrant shell
