核心服务

Core service

Full‑range Trenchless External Inspection and Diagnosis

——Comprehensive physical examination of the pipeline exterior

Equipped with full‑set detection devices, non‑excavation full‑line scanning performs:
1. Anti‑corrosion coating integrity detection, damage localization & insulation evaluation
2. Pipe‑to‑soil potential test, cathodic‑protection effectiveness assessment & failure‑section identification
3. Soil corrosiveness, AC/DC stray‑current full‑range scanning & interference quantification
4. Corrosion‑rate monitoring, pipeline corrosion‑speed judgment & visualized risk‑map output
Defect Excavation Verification and Repair Guidance

— Precisely eliminate external lesions

Targeted excavation verification for marked high‑risk points with on‑site technical support:
1. Coating defect repair scheme design
2. Stray‑current drainage & cathodic‑protection upgrading guidance
3. Graded disposal for corrosion defects to avoid blind large‑scale excavation
Comprehensive Evaluation of External Corrosion Integrity for Pipelines

——Establish a long‑term operation and maintenance system

Conduct standardized ECDA from measured data and build pipeline external‑protection digital archives:
1. Evaluate overall external‑corrosion grade & calculate pipeline residual service life
2. Deliver standard‑compliant assessment reports satisfying national and state‑owned pipeline‑network acceptance
3. Customize long‑term O&M schemes to shift pipeline network from passive emergency repair to proactive prevention

为客户带来的价值

The value brought to the customers

cost reduction and efficiency improvement

Trenchless inspection reduces excavation costs by 30%-60%, shortens pipeline shutdown duration, and avoids traffic and municipal supporting‑facility losses caused by large‑scale excavation.

Prolong lifespan

Accurately repair anti‑corrosion damages and eliminate corrosion triggers, which can extend the designed service life of pipelines by 10‑20 years and realize the preservation of fixed‑asset value

Consolidate the defense line

Conduct advance inspection for hidden risks of corrosion perforation and leakage, and prevent major safety accidents such as explosions, medium leakage, and soil‑water pollution.

Compliant and hassle‑free

The testing procedures and reporting standards are fully compliant with national as well as oil‑gas and gas industry specifications, and have successfully passed various inspections covering safety, environmental protection and special‑purpose equipment.

Cost Optimization

Single‑time inspection investment avoids huge expenditures on emergency repairs, production halts, administrative penalties and third‑party compensation, establishes an active preventive operation and maintenance mode, and delivers remarkable long‑term benefits.

sound system

Establish a full‑life‑cycle inspection and evaluation system to realize the transformation from "passive emergency repair" to "active prevention", with remarkable long‑term comprehensive benefits.
