With four core advantages of бат бөх чанар, health safety, intelligence and sustainability, brass fittings have become the standard configuration for water supply and drainage, HVAC, fire protection and smart water systems in modern cities, and their market penetration keeps rising steadily.

Manufacturing of Гуулин холбох хэрэгсэл

The manufacturing of brass fittings is a systematic engineering integrating materials science, precision forming, mechanical processing and surface engineering. Its craftsmanship level directly determines the fitting’s sealing performance, даралтын эсэргүүцэл, corrosion resistance and service life.

Our products are mainly manufactured by adopting the above processes.

They have obtained global drinking water contact certifications, орно NSF/ANSI 61, WRAS and GB 18145, complied with pressure grade standards PN16/PN25 and seismic specifications FM/UL and passed green building material evaluation, forming a closed loop of performance verification – certification testing – market access.

Performance and Advantages of Brass Fittings

Core Performance

1. Mechanical strength: Tensile strength of 300–500 MPa; elongation of 15%–40%; excellent resistance to water hammer impact.
2. Зэврэлтэнд тэсвэртэй: Resistant to fresh water, gas and atmospheric oxidation; alloyed with As/Sb/P to inhibit dezincification.
3. Thermal stability: Thermal conductivity of 100–120 W/(m·K); melting point approx. 900–940℃; thermal expansion coefficient approx. 19×10⁻⁶/℃.
4. Biosafety: Slow release of copper ions at 0.1–0.5 mg/L; inhibits Escherichia coli, Legionella and biofilm formation.
5. Electrical & electromagnetic performance: Conductivity approx. 28% IACS; outstanding grounding continuity and anti-electromagnetic interference capability.

Comprehensive Advantages

1. Үйлчилгээний хугацаа & засвар үйлчилгээ: Service life of 30–50 years; maintenance-free or low-frequency replacement, with lower full life-cycle cost.
2. Safety level: Fireproof, explosion-proof, water hammer-resistant and seismic flexible joints are well-developed. It enhances the safety redundancy of urban lifelines, suitable for gas, fire protection and emergency systems.
3. Construction compatibility: Compatible with thread, push-fit and press-fit connections; controllable torque; complete BIM component library. Friendly to prefabricated and modular construction, shortening the construction period by 20%–30%.
4. Pressure resistance grade: Өндөр даралтын эсэргүүцэл, plus water hammer resistance and copper ion bacteriostasis, extends pipeline service life and reduces water leakage rate.

The Role of Brass in the Sustainable Development of Modern Cities

Brass has evolved from a traditional basic connecting material into a core carrier for sustainable development strategies in modern cities and industrial systems.

1. Environmental Sustainability

As a copper-based alloy, brass features a low melting point (approximately 900℃) and high metallurgical stability. The energy consumption for remelting recycled brass is only 15%–20% of that required for primary ore smelting, with an end-of-life recycling rate exceeding 90%. Recycled brass maintains consistent performance without degradation, enabling a high-efficiency closed-loop recycling system.

Үүнээс гадна, the full-life-cycle carbon emission of brass is lower than that of stainless steel and some engineering plastics, delivering superior low-carbon performance. From the perspective of modern urban sustainable development and public health, its high thermal conductivity improves the COP of heat pumps and floor heating systems, while its low flow resistance reduces water pump energy consumption by 10%–20%. Non-toxic and harmless, brass serves as a typical practical material for the urban mineral strategy.

2. Economic Sustainability

Long-service-life assets and full-lifecycle cost optimization

Application of Гуулин холбох хэрэгсэл

Our products are mainly applied in water supply and drainage systems.
