SOE Benchmark.
Setting an SOE Benchmark: Intelligent Zonal Temperature Control and Full Data Traceability Empower High-quality Production of Large-scale Infrastructure Segments
[Project Background]
Project: Langfang, Hebei — CCCC Prefabricated 182-acre green industrial base
Equipment: NDG low-pressure steam generator + zone intelligent temperature control + slide-type insulated curing tents
Product: Tunnel segments, rail transit & municipal precast elements; annual capacity 220,000 m³ concrete
Client: China Communications Prefabricated Building Technology Co., Ltd. — SOE precast production base
Pain point
Manual temperature control across multiple zones → large variance, cracks, high rejection rate
01 Non-special equipment
No boiler room, no annual inspection, simplified plant safety management
02 11 independent zones
Each with custom 4-stage curing curve; eliminates temperature-variance cracking
03 Insulated tents lock temperature & moisture
Boosts early strength, accelerates mold turnover
04 Fully automatic, unattended
One-touch start; no dedicated steam-curing operator
05 Full data traceability
Auto-logged curing curves meet SOE quality & audit requirements
Client feedback
Safety & environmental compliance passed on first inspection
Tent + hose combo eliminated fixed piping investment
Clean, dust-proof container unit — minimal daily maintenance
Highlight
SOE benchmark — standardized segment curing solution, replicable for high-end infrastructure with strict quality control..
