2PE Heat Shrink Sleeves Successfully Delivered, Inspected, and Accepted On-Site We are proud to announce that CNpetro has been officially approved as a supplier for Snam's National Gas Pipeline Replacement Programme in Italy. Our 2PE heat shrink sleeves have been successfully manufactured, delivered to the project site, and passed on-site inspection and acceptance — marking a significant milestone in our continued expansion into the European pipeline market. Project Overview Snam is one of Europe's leading energy infrastructure operators and the primary operator of Italy's national gas transmission network. Its pipeline replacement programme is a large-scale initiative aimed at upgrading aging gas transmission lines to meet modern safety, environmental, and performance standards. For this project, CNpetro supplied 2PE heat shrink sleeves designed for the corrosion protection of field joints on two-layer polyethylene (2PE) coated pipelines. These sleeves are engineered to deliver reliable adhesion, mechanical protection, and long-term corrosion resistance in buried gas transmission environments. Product Delivered: 2PE Heat Shrink Sleeves Our 2PE heat shrink sleeves are specifically designed for field joint coating on 2PE pipelines. Key features include: Delivery & Acceptance The 2PE heat shrink sleeves were manufactured at our production facility, subjected to rigorous quality control, and shipped to the project site in Italy. Upon arrival, the products underwent on-site inspection and acceptance by the project's quality assurance team. We are pleased to confirm that all delivered products passed inspection and were formally accepted for use in the pipeline replacement programme. This successful delivery demonstrates CNpetro's capability to meet the stringent quality, documentation, and logistical requirements of European energy infrastructure projects. Why This Matters Being selected as a supplier for Snam's National Gas Pipeline Replacement Programme is more than a commercial achievement. It represents: Recognition of product quality — Our heat shrink sleeves meet the demanding requirements of one of Europe's most respected gas transmission operators Competitiveness in the European market — CNpetro can compete with established European suppliers on quality, delivery, and cost Proven track record — Successful delivery and on-site acceptance provide a strong reference for future European projects Commitment to standards — Our products are engineered and tested to international standards, not just local requirements Cross-linked polyolefin backing — Provides excellent mechanical strength and impact resistance High-performance hot-melt adhesive — Ensures strong bonding to steel and PE coatings Uniform shrinkage — Forms a tight, watertight seal around the weld joint Compatibility — Designed for 2PE, FBE, and compatible mainline coatings Standards compliance — Manufactured to meet ISO 21809-3 and EN 12068 requirements About CNpetro CNpetro specializes in the research, development, and manufacturing of pipeline corrosion protection materials, including: Heat shrink sleeves for 2PE, 3PE, 3PP, and FBE pipelines Epoxy primers Viscoelastic anti-corrosion tapes Outerwrap tapes and waterproof topcoats With a strong technical foundation built on collaboration with Tianjin University of Science and Technology and national pipeline design institutes, CNpetro focuses on high-temperature product innovation and benchmarks its products against international standards. Looking Ahead This project with Snam marks an important step in CNpetro's European market development. We are committed to supporting Italy's gas infrastructure modernization and to building long-term partnerships with European pipeline operators, EPC contractors, and distributors. We thank our team, our partners, and Snam's project team for their trust and collaboration. CNpetro — Protecting pipelines. Advancing performance.

The third-generation petrolatum anti-corrosion tape is composed of synthetic fiber base material and mineral grease adhesive. It is a mixture of inert mineral grease, fillers, corrosion inhibitors, rust conversion agents, and other materials. A flexible ribbon roll made by impregnating and coating synthetic fiber substrates.   The third-generation petrolatum grease anti-corrosion tape can be applied in industries such as oil and gas, chemical, urban construction, shipbuilding, etc., to prevent steel pipelines, irregular components, such as flanges, valves, tees, and the overall and bottom edge plates of storage tanks.   The hydrophobic and anti-corrosion properties of the third-generation mineral grease anti-corrosion tape are very suitable for humid areas and underwater environments, providing perfect sealing for equipment that requires anti-corrosion. It has the characteristics of long-term non hardening, non cracking, and good flexibility. It also has good corrosion resistance and electrical insulation to acid, alkali, and salt substances.   Product features:   1. It can effectively prevent the infiltration of water vapor and oxygen.   2. It can effectively resist the influence of soil stress.   3. The surface treatment requirements are low and only need to reach the national standard of St2 level.   4. Petrolatum tape has good plasticity and flexibility, can be kneaded into any shape, and is suitable for anti-corrosion of any regular and irregular workpiece surface.   5. The product is formed in one go and has stable quality.   6. Simple construction, fast speed, no curing time, can be backfilled after wrapping.   7. Petrolatum tape meets the requirements of cathodic protection.   8. Long anti-corrosion life.

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.” About CNPetro Tianjin CNPetro specializes in the research, development, and manufacturing of pipeline corrosion protection materials, including heat shrink sleeves, epoxy primers, and viscoelastic coatings.
