Water Supply & Drainage

Tank-type non-negative pressure water supply equipment, also known as pipe network stacked pressure water supply equipment, is a secondary pressurized water supply system designed to connect directly to municipal water networks. These units utilize the residual pressure of the municipal pipe network to add pressure in series, ensuring that the municipal network's pressure never falls below a set protection level—typically no lower than 1.2kg.

Applications:These systems are essential for providing secondary pressurized water to residential communities, high-rise buildings, and municipal zones where the direct municipal pressure is insufficient. Key components requiring precision manufacturing include non-negative pressure buffer tanks, vacuum suppressors, pump units, and stability compensators.

Manufacturing Hurdles:

• Extensive Welding Scope: A single system requires high-volume welding across buffer tanks, stability compensators, and multiple pipe-to-flange connections for inlets, outlets, and butterfly valves.
• Manual Inefficiency: Relying on manual labor results in low production efficiency and long manufacturing cycles that struggle to meet market demand.
• Quality Inconsistency: Manual welding often leads to inconsistent weld quality and poor repeatability, which can compromise the structural integrity of the pressurized units.
• Risk to Service Life: Since these units operate under constant pressure, weld quality is the primary factor determining the equipment's sealing reliability and overall service life.
• Labor Bottlenecks: The heavy reliance on skilled welders creates a high risk of human error, such as welding deviations or missed welds, particularly during large-scale production.

• Efficiency Surge: Manufacturers have achieved an overall welding efficiency increase of more than 60%.
• Enhanced Precision: Automation has significantly reduced the occurrence of manual errors such as missed welds or leakages.
• Cycle Time Reduction: The streamlined automated process drastically shortens production cycles and speeds up delivery to market.
• Technical Stability: The equipment maintains a very low failure rate and provides stable, consistent weld formation that meets the highest technical standards.
