For a long time, many ultra-high voltage operation teams focused their management on the ultra-high voltage main equipment, paying little attention to the wear resistance of the transmission pipes. They believed that if the outer layer wore through, they could simply replace the pipe without much loss. However, as ultra-high voltage projects grow larger and the operating environment becomes more complex, the premature wear and tear of a single ordinary ultra-high voltage resin pipe not only incurs the purchase cost of the pipe itself but also disrupts the workflow and requires re-laying the pipeline. The labor and time losses from a single downtime are often ten times the cost of the pipe purchase.

 

Now, more and more ultra-high voltage engineering teams are incorporating wear-resistant ultra-high voltage resin pipes into their core maintenance list. By improving the wear life of the pipes, they directly drive improvements in the overall project efficiency, significantly reducing the comprehensive operation and maintenance costs of the project from a full lifecycle perspective.

 

From Frequent Pipe Replacement to Dedicated Preventative Maintenance for Wear-Resistant Working Conditions

 

Traditional ultra-high pressure pipe management involves replacing pipes only after the outer layer is completely worn through and the pipe has failed. This approach not only results in significant material waste but also poses a high risk of accidental pipe bursts. The current mainstream maintenance approach has shifted to preventative maintenance based on wear-resistant working conditions: an independent usage log is established for each wear-resistant ultra-high pressure resin pipe based on the ground roughness, dragging frequency, and operation duration of different work scenarios. This log records the cumulative dragging distance and operation duration, and corresponding outer layer wear inspection cycles are pre-set.

 

During routine inspections, maintenance personnel can use simple outer layer thickness measurements and visual inspections to promptly detect early problems such as excessive localized wear and sheath displacement. These issues are addressed before wear damage penetrates the internal reinforcement layer, preventing sudden pipe failure during operation. This approach can increase the overall service life of the pipes by more than 30% and reduce the probability of sudden downtime in ultra-high pressure operations by 70%.

 

Supporting scenario-based services further unlock the value of wear-resistant pipes

 

The mature wear-resistant ultra-high pressure resin pipe supply system now goes beyond simply delivering pipes; it extends to providing comprehensive scenario-based support services. For different high-wear scenarios such as ship rust removal, building demolition, and mine blockage clearing, it provides corresponding selection guidance, wear-resistant sheath installation specifications, and operation and maintenance training. This helps on-site personnel avoid common mistakes such as scratching from sharp objects during pipe dragging and excessive bending, further slowing down the wear rate of the pipes.

 

In some scenarios, customized pre-assembled assembly services can also be provided. Standardized crimping of pipes and ultra-high pressure connectors is completed in advance, and pressure testing and wear resistance performance sampling are performed on each pipe before delivery. Direct on-site installation and use are possible, eliminating the need for on-site processing. This complete support from product to service transforms wear-resistant ultra-high pressure resin pipes from consumables in high-wear scenarios into a core support for ensuring long-term efficient operation and cost reduction in ultra-high pressure operations.
