Tianjin CNPETRO, a leading manufacturer of pipeline corrosion protection solutions, is proud to announce that its 3LPE heat shrink sleeves (HSS) have been selected for use in field joint coating operations for Midland Oil Company (MdOC), a subsidiary of the Iraqi Ministry of Oil.
The project involves the application of 3LPE HSS as part of the field joint coating system for pipeline construction in MdOC-operated oilfields. This collaboration marks a significant milestone in [Company Name]’s continued expansion into the Middle East energy infrastructure market.
Project Background
Midland Oil Company, headquartered in Baghdad, is one of Iraq’s state-owned oil companies responsible for oil and gas exploration, development, and production across multiple fields . The company operates under the Iraqi Ministry of Oil and has been actively advancing its production capacity through various development projects .
Iraq’s oilfields present particularly demanding conditions for pipeline materials, including ambient temperatures reaching up to 50°C, abrasive sandstorms, and highly corrosive soil environments containing H₂S, CO₂, and chlorides . These factors make the selection of high-performance field joint coating materials critical for ensuring long-term pipeline integrity.
Product Application
The 3LPE heat shrink sleeves supplied by [Company Name] are designed specifically for the corrosion protection of field joints on three-layer polyethylene (3LPE) coated pipelines. The 3LPE coating system—comprising fusion-bonded epoxy (FBE), adhesive, and polyethylene layers—is widely recognized as one of the most effective anti-corrosion solutions for buried pipelines .
Heat shrink sleeves are the most commonly used field joint coating material for 3LPE pipelines, offering high insulation resistance, excellent water resistance, and good flexibility . The system typically consists of a two-component epoxy primer, a radiation cross-linked polyethylene backing, and a hot-melt adhesive layer .
The field joint coating system ensures that welded joints achieve corrosion protection performance equivalent to the factory-applied mainline coating, creating a continuous and durable protective barrier across the entire pipeline length.
Commitment to Quality
[Company Name]’s 3LPE heat shrink sleeves are manufactured under rigorous quality control procedures and comply with relevant international standards for pipeline field joint coatings. The products feature excellent peel strength, reliable cohesive failure performance, and ease of installation in field conditions .
We are honored to support Midland Oil Company in its ongoing pipeline infrastructure development,This project reflects our commitment to delivering reliable corrosion protection solutions for the most demanding oil and gas environments.”
