I. Project Background
This project is a large-scale centralized heating system renovation project for urban communities in Mongolia, covering the underground heating network and heat exchange station units of a large residential area. Mongolia experiences long, harsh winters, with temperatures reaching as low as -40°C. All heating pipelines are directly buried, placing stringent requirements on valves for freeze protection, temperature difference resistance, zero leakage, and long service life. The existing old-style segmented ball valves had many welds and were prone to leakage and freezing after being buried underground, leading to frequent heating outages and severely impacting residents' winter heating needs. The client learned about Yuming Valves' extensive experience in supporting heating networks in cold northern regions through online channels. They sent their procurement requirements via email. After technical communication and drawing selection, both parties purchased Yuming fully welded ball valves in bulk for use in the community's underground heating main and branch networks and heat exchange station units. The entire set of products was successfully installed, commissioned, and put into operation for heating.
II. Customer's Core Operating Conditions and Procurement Needs
Low-Temperature Operating Conditions: Valves are buried underground for extended periods and must withstand extreme cold in winter and large temperature differences in summer, preventing valve body cracking and media leakage;
Operating Cycle: The cost of excavating and maintaining underground pipelines in communities is extremely high, requiring an integrated sealing structure for the valve body, eliminating external leakage points and requiring no maintenance;
On-the-Site Services: Support for moisture-proof and reinforced export packaging in wooden crates, simultaneous provision of product drawings and pressure test reports, and provision of installation technical guidance;
Factory Quality Inspection: All valves undergo 100% shell strength and sealing water pressure testing.
III. Core Product Supply: Fully Welded Thermal Ball Valves
This project utilizes Yuming's integrated fully welded ball valves, specifically designed for centralized heating networks in high-altitude and cold regions:
Integrated Fully Welded Valve Body Structure: No separate flanges, no exposed leakage points, perfectly compatible with underground direct burial installations, completely solving the common problem of freezing and cracking at the flanges of traditional two-piece ball valves;
High and Low Temperature Resistant Sealing: The valve seat uses high-temperature and low-temperature resistant composite materials, ensuring stable sealing performance within a temperature range of -45℃ to 200℃, preventing leakage even with frequent start-stop cycles during the heating season;
Integrated Insulation Structure:The valve body can be matched with insulation layers of the same specifications for the heating pipelines, resulting in aesthetically pleasing and uniform pipeline splicing on-site, reducing heat loss;
Full Specification Coverage:Covers the entire range of large-diameter main pipelines in communities and small-diameter branch pipelines in buildings, with unified pressure standards, compatible with heat exchange stations and underground pipe networks, facilitating future spare parts inventory.
IV. Project Implementation Guarantee
1.
Rigorous Full-Scale Factory Testing
Each fully welded ball valve undergoes a 1.5 times rated pressure test on the shell and a bidirectional zero-leakage sealing test after leaving the production line. All test data is archived.
2.
Standardized Export-Oriented Moisture-Proof Packaging
Valve are individually wrapped with anti-rust film and paired with a custom-made solid wood fumigated crate, providing adequate cushioning and protection suitable for long-distance land transportation and open-air transshipment, avoiding damage from bumps and corrosion during transport.
V. Project Operation Results and Customer Feedback
After the entire fully welded ball valve system was put into operation for a full heating season, there were no leaks or malfunctions in the community's underground heating network, completely eliminating the problems of frequent excavation and repairs and temporary heating outages that existed in previous years. The integrated fully welded structure is impervious to the extreme cold winters of Mongolia, and the insulation design significantly reduces heat loss in the network, resulting in a significant improvement in the stability of the community's heating system. Feedback from the client's on-site project manager: The extremely low temperatures of Mongolia's winters pose a significant challenge to heating valves. Yuming's fully welded ball valves, with their one-piece molding and leak-proof construction, adhered to strict factory quality control standards and included complete documentation. The entire process, from sea freight to on-site installation, was seamless. Yuming is a reliable valve supplier suitable for local centralized heating projects, and we will continue to deepen our cooperation on similar community construction projects in the future.
VI. Project Summary
The Mongolian community centralized heating project is a typical example of Yuming's fully welded ball valves used in underground direct-buried heating pipelines in high-altitude and cold regions. Relying on its integrated leak-proof welded structure, product design resistant to extreme temperature differences, standardized factory quality control, and one-stop overseas delivery service, the project precisely addresses the industry pain points of easy leakage and difficult maintenance in Mongolia's frigid heating pipelines, fully demonstrating Yuming's professional supporting capabilities in the field of municipal heating and high-altitude heating pipeline valves.
