Steel Guardian of Safety —— Yong'an Fire Extinguishing Cylinders

Date:2025.11.28

In the modern fire safety system, fire extinguishing gas cylinders, as the core component of fire extinguishing systems, undertake the important mission of storing fire extinguishing media and responding quickly to fires. As a professional manufacturer of fire-fighting equipment, Yong'an's series of fire extinguishing cylinders have become a reliable choice in the field of fire safety due to their advanced manufacturing processes, strict quality control and comprehensive specification coverage. This article will take you to fully understand the technical characteristics, product advantages and application value of Yong'an fire extinguishing cylinders.

I. Product Positioning: A Reliable Backing in the Professional Fire Protection Field

Yong'an's series of fire extinguishing cylinders are specially designed for various fire-fighting scenarios, integrating advanced manufacturing processes and high-quality material selection, with excellent pressure resistance and structural stability. Whether it is small portable fire extinguishing equipment or large fixed fire extinguishing systems, Yong'an fire extinguishing cylinders can provide stable and reliable medium storage solutions, offering key guarantees for fire response.

The product family is mainly divided into two series:

• Portable seamless steel cylinders for CO₂ fire extinguishing: Suitable for portable fire extinguishing equipment, flexibly responding to various initial fires.

• Large-capacity seamless steel cylinders for fire protection: Covering 30L-130L specifications, suitable for fixed fire extinguishing systems and large fire-fighting equipment.

II. Technical Advantages: Meticulous Quality Assurance

1. Selection of High-Quality Materials

Yong'an fire extinguishing cylinders strictly control the selection of materials, choosing the most suitable materials according to different application scenarios:

• The portable series adopts 34CrMo4 alloy steel, which has excellent strength and toughness, and can withstand high pressure and external impact.

• The large-capacity series adopts HP345 material, which balances high strength and good processing performance, ensuring the stability of the cylinder body in various environments.

• All materials have undergone strict quality inspection and meet the requirements of relevant national standards.

2. Strict Pressure Standards

Pressure performance is the core indicator of fire extinguishing cylinders, and Yong'an's products perform excellently in this regard:
