Project description: The project belongs to the AHDEB oil field being developed by AL-WAHA PETROLEUM co., Ltd. In view of the serious corrosion and scaling of the pipeline and the high operating pressure, our company adopts the " concentric diameter reduced HDPE pipe " to carry out HDPE lining repair services. The pipe size is 6-18 inches, and the conveying medium is oil and water. Since 2015, we have completed a total of 400km of work.

The project pipeline belongs to the high-sulfur gas field in the northeastern part of Sichuan Province Xuanhan Kaixian block gas field project internal gathering and transportation project. The sewage return pipe consists of two parts:

The first part is from the gas plant ~ F field gas field water injection pipeline, which GB271 ~ GB267 ~ C1 ~ C2 pipe section, GS042 ~ GF41-1 ~ GF38 ~ GS038 pipe section with the gas line with the ditch laying, see the cross-sectional view The In addition, the ancillary structures such as the "F-site and the main gas gathering section of the gas gathering station" are considered. The pipeline length is 10.224km long and 10.486km long. Pipeline crossing the road 16 times, medium-sized rivers through 1 times, small rivers and ditches 10 times. (With pipeline plan)

The second part of the return pipeline is from the "Y-contact to Huanglong 3 Well", the pipeline horizontal length of 3.140km, real length of 3.243km. Pipeline crossing the road 8 times, small river 1 times.

The third part increases the workload: 5km.

             Project: Northeast Sichuan high pressure water injection pipeline lining

             Construction: Shandong Kelin Ruier Pipeline Engineering Co., Ltd

This project is located in Majnoon oil field, which is operated by Antonoil Services DMCC under the authorization by Iraqi National Oil Company (BOC),  our company adopts the " concentric diameter，reduced HDPE pipe" to solve the corrosion problem of the pipeline by lining the newly laid steel pipe with HDPE pipe.

The project work consists of design, procurement and construction services for a new 27.2km 14 inches water transmission pipeline. We were responsible for the overall design of the project, supply of lining pipes and construction of the lining works.

This project is located in Majnoon oil field, which is operated by Antonoil Services DMCC under the authorization by Iraqi National Oil Company (BOC),  our company adopts the " concentric diameter reduced HDPE pipe" to solve the corrosion problem of the pipeline by lining the newly laid steel pipe with HDPE pipe.

The project work consists of design, procurement and construction services for a new 14.25km water transmission pipeline of 8 and14 inches. We were responsible for the overall design of the project, supply of lining pipes and construction of the lining works.

The project belongs to the Majnoon oil field developed by Shell Oil Company. The field is located 60 kilometers north of Basra province in Iraq. The pipeline starts from the Saudi Arabia River and ends at Majnoon Oil Field CPF. 26km of 12-inch PE pipe lining works in this project has been completed.

The water transmission pipeline stretching from Laoyemiao to the Gaoshangbu Central Station and the Beibao Village estuary connecting the sea section is located within an ecological protection zone. Due to severe pipeline corrosion, multiple leaks have occurred. To mitigate the environmental risks associated with these leaks, the original pipeline has been repaired using HDPE lining and high-pressure composite flexible pipe lining technologies.

The gathering and transportation system of the Southern Oilfield has been in service for an extended period. Influenced by factors such as the regional environment, climate, internal conveying medium, and pipe material, inspections and investigations have revealed varying degrees of corrosion thinning in some pipelines. The safety hazards associated with these pipelines are becoming increasingly prominent, posing a significant constraint on production. Moreover, pipeline leaks could lead to environmental pollution incidents, resulting in adverse impacts. To ensure the safe operation of the pipelines, internal lining repair is being implemented on those identified with safety risks. This project involves trenchless repair of a total of 20.89 km of pipeline.

China Petroleum & Chemical Corporation Guangzhou Branch Refinery Wastewater Unit Outfall Pipeline Rehabilitation Project is located in Huangpu District, which is a DN600 concrete socket pipeline with a length of about 2 kilometers. This project adopts lining repair technology and has been completed.
