Various pipelines with “evaporating, emitting, dripping and leaking” problems need to be repaired through excavation and even replaced, which requires huge investment. Meanwhile, it also destroys roads, damages the environment and blocks traffic, making people very dissatisfied.

Shandong Shenbon Kelinruier Pipeline Engineering Co., Ltd. is one of the most powerful non-excavation pipeline repair engineering contractors in China. The independently developed “equal diameter compression PE pipe lining repair on-line pipeline technology” is a revolution of pipeline repair, which abandons the “zipper” road.

This technology temporarily reduces the external diameter (slightly larger than the internal diameter of the pipeline to be repaired) of a modified polyethylene pipe through a multi-stage radial uniform compression device, and pulls the modified polyethylene pipe into the pipeline to be repaired, 12 hours later, the outer wall of the modified polyethylene pipe with memory feature is tightly attached to the inner wall of the main pipeline to form a whole when the original caliber is recovered, thus effectively fulfilling the aim of internal corrosion prevention repair of pipelines. The technology eliminates the trouble caused by repairing the pipeline through whole excavation, and can make the old pipeline run for 50 years again healthily.

Technical Features：

1、One-time insertion of more than 1,000m；
2、No corrosion, water supply pipeline repair which can avoid secondary pollution；
3、Greatly improve the running pressure of the old pipeline (for example, the pressure of the repaired cement pipe can reach 2MPa.)；
4、Low cost (far lower than the cost of a newly built pipeline)；
5、Long service life, capability of making the old pipeline run for 50 years again healthily；
6、Reduce the frictional resistance of the pipeline, improve conveying capacity

Application Range：
1. Various oil, gas and water pipelines in petroleum industry and petrochemical industry
2. Urban water supply & drainage (steel pipes, cast iron pipes, cement pipes and so on) and gas pipelines

Other Technologies:
● The high-accuracy pipeline magnetic flux leakage on-line detection system takes a pipeline conveying medium as forward power, guides a detector to walk in the pipeline, carries out on-line direct nondestructive detection on the pipeline, and is the most perfect pipeline detection means recognized at home and abroad at present.
● The long-distance pipeline leakage alarm positioning system can monitor the transportation safety of the pipeline under all-weather condition, intelligently identify the pipeline running abnormal condition, immediately report pipeline leakage and accurately judge the accident position.
● The detection range and detection effect of the pipeline endoscopic detection robot are at domestic leading level.
● Continuous physical cleaning of long-distance pipeline, pipeline three-layer composite lining repair technology

The company wins the trust of customers by its two invention patents, fifteen utility model patents and professional service. Shenbon Kelinruier’s customers are spread across the country, Daqing Oilfield in Songnen Plain to the north, Guangzhou at Pearl River Delta to the south, deserts and gobis in Tarim Basin to the west, Shengli Oilfield and Dagang Oilfield at the Coast of Bohai Sea to the east. We create this strong brand “Shenbon Kelinruier” in the field of non-excavation by technology and service.

Zhou Changshan, the Chairman, and Guo Yuejin, the General Manager, together with all staff, express our warm congratulations to the 50th anniversary of the founding of Adult Education College of University of Petroleum, and extend sincere greetings to teacher & student staff and schoolmates of Adult Education College of University of Petroleum!
