Case Study: Boming Weixing Ink Technology's DN1800 Ultra-Large Diameter Pipe Repair Project a Complete Success
Recently, Bomingwei Technology's wholly-owned subsidiaryXingmo TechnologyWe provided DN1800 large-diameter UV-CIPP repair hoses for a pipeline renovation project in the central urban area of Shanghai, along with Bomingwei's self-developed UV curing repair equipment, which helped the project successfully complete the trenchless repair of ultra-large diameter drainage pipelines.
「 Project Background 」
Recently, Bomingwei Technology's wholly-owned subsidiaryXingmo TechnologyWe provided DN1800 large-diameter UV-CIPP repair hoses for a pipeline renovation project in the central urban area of Shanghai, along with Bomingwei's self-developed UV curing repair equipment, which helped the project successfully complete the trenchless repair of ultra-large diameter drainage pipelines.
「 Technical challenges 」
Large diameter + large wall thicknessWide-width weaving, resin impregnation, uniformity, waterproof outer membrane lamination, etc.The requirements are extremely high; ordinary materials are prone to delamination, lack of adhesive, and insufficient local wetting.
Large-diameter pipes have higher requirements for UV light intensity and coverage. Precise control of light intensity, temperature and travel speed is necessary to avoid insufficient curing or overheating damage, which would affect the quality of the repair.
The city center is plagued by heavy traffic and limited work space. Located under an overpass, construction is only permitted for short periods from 9:00 PM to 6:00 AM the following day, putting significant pressure on the project schedule and safety management.
Large-diameter pipe repair procedures are complex.
Large diameter pipes need to be prepared in advanceHigh-pressure airbagSealing and stopping water; the material discharge well opening is too small and needs to be enlarged and the top of the well chamber needs to be dismantled, and the pipeline to be repaired continues to be invaded by external water, requiring additional water pumping, which increases the number of procedures and lengthens the construction period; at the same time, the requirements for the hose to be pulled into place, inflated and fitted, and the stability control of the whole process are extremely high.

"Benchmark Significance"
The successful repair of the DN1800 in this first-tier city marks a significant achievement for Xingmo Technology.extra-large diameter pipeUVCIPP Materials and ConstructionThe field has reached a new level:
▶ VerificationDN150–DN2400 Total pipe diameterReliability of self-developed material systems
▶ Strengthen integrated delivery capabilities of materials, equipment, and technical services
▶ Provides a replicable benchmark case for trenchless repair of ultra-large diameter main pipelines.
In the future, Xingmo Technology will continue to focus on the field of trenchless repair materials, serving key municipal projects across the country with higher standards, more stable quality, and stronger delivery, and helping to upgrade urban underground pipe networks to a high standard.
