Nine Years of Dedication, Renewed Progress | YiHuiDe Completes Factory Upgrade & Relocation with Fully Upgraded Capacity and R&D Systems

In 2020, on the occasion of the ninth anniversary of Tianjin YiHuiDe Anti-Corrosion Materials Co., Ltd., the company completed the overall relocation and upgrade of its production base. Facing the dual challenges of the industry environment and the pandemic, the company built a large-scale new plant through sustained R&D investment, production system iteration, and talent team development, achieving a comprehensive leap in production capacity, quality control, and R&D capability. Since its founding, YiHuiDe has remained deeply focused on the pipeline anti-corrosion materials sector. Over nine years, it has adhered to technology-driven development, continuously investing in product R&D and process optimization while cultivating professional technical and management teams, gradually building a technology and production system covering the full range of products including heat shrinkable tapes, heat shrinkable sleeves, and repair materials. In 2020, the external environment was under pressure, and the pandemic brought multiple challenges to production, delivery, and project progress. The company team overcame difficulties and, while ensuring stable order delivery, completed the planning, construction, and overall relocation to the new plant on schedule, moving into a larger and better-organized modern production base. This upgrade was implemented across four dimensions - capacity, equipment, quality control, and R&D: - The production workshop area was expanded, equipped with automated production lines and complete sets of advanced manufacturing equipment, greatly improving large-scale delivery capability; - The testing laboratory and quality control system were upgraded in parallel, with full-process quality management standards further refined; - R&D office space and laboratory conditions were optimized, providing hardware support for technology iteration and new product development. This factory relocation and upgrade is a milestone of YiHuiDe's nine years of development and proof of the company's resilience and comprehensive strength. Standing at a new starting point, the company will continue to deepen its commitment to the anti-corrosion materials sector, serving global customers' pipeline anti-corrosion needs with more stable capacity and more reliable quality.

Knowledge Sharing | Anti-Corrosion Heat Shrinkable Tape: Core Process, Application Scenarios and Construction Advantages FAQ

In pipeline anti-corrosion projects, choosing an anti-corrosion material that can withstand the test of the environment is the key to ensuring pipeline service life. To help customers better understand our product advantages and scope of application, we have compiled this FAQ to give you an in-depth look at the core process and outstanding performance of our products. Q1: What are the core process and materials of your products? A: Our products are mainly composed of a polyethylene (PE) substrate compounded with EVA hot melt adhesive. Outer substrate: Made from high-quality polyethylene as the main raw material, compounded with light stabilizers, antioxidants, tackifying resins, and polar materials, giving the product outstanding aging resistance and mechanical protection. Inner hot melt adhesive: The main raw material is high-performance EVA. For working conditions with special high- or low-temperature requirements, our technical team can formulate dedicated adhesive recipes tailored to your needs. Q2: Compared with similar products on the market, where do your core quality advantages lie? A: Our products stand in the market on "very good quality", with core construction advantages reflected in the following three aspects: Strong adhesion and extremely high peel strength: The composite layer forms an extremely firm chemical and physical bond with the pipe surface, effectively resisting extreme soil stress and mechanical damage. Perfect fit, no edge lifting: Thoroughly overcomes the industry pain point of edge lifting and opening commonly seen with inferior materials after installation, ensuring a long-lasting, dense anti-corrosion layer. Excellent temperature adaptability: The product has an extremely high softening point and remains stable without flow at high temperatures; it also offers excellent low-temperature workability, maintaining outstanding flexibility and bonding even when installed in severe cold, without cracking. Q3: In which pipeline projects are the products mainly applied? A: Thanks to their excellent anti-corrosion and sealing performance, our heat shrinkable tapes/sleeves are widely used in three major scenarios: long-distance gas pipelines, thermal insulation pipelines, and water supply and drainage pipelines. Q4: The substrate conditions of long-distance gas pipelines are usually complex. How is the bonding performance? A: Extremely excellent. The bonding substrate of long-distance gas pipelines is the most complex, yet our high-adhesion hot melt adhesive can simultaneously adapt to various materials including the steel body, polyethylene (PE) outer layer, residual solvents from paint layers, and dedicated anti-corrosion primers, achieving all-round dense wrapping and preventing the intrusion of moisture and corrosive media. Q5: What are the construction characteristics of thermal insulation pipelines and water supply/drainage pipelines? A: In these scenarios, the bonding surface structure is relatively simple, requiring bonding mainly with the polyethylene (PE) outer layer of the pipe. Thanks to the excellent compatibility between the PE substrate and EVA hot melt adhesive and the extremely high peel strength, construction is fast and efficient, easily achieving a "seamless fusion" sealing effect between pipes. 💡 Conclusion: Whether it is low-temperature construction in freezing regions or complex long-distance pipeline substrates, we are always committed to providing you with the most reliable pipeline anti-corrosion solutions that do not lift at the edges, are high-strength, and dependable. If you have more questions about our process, or need anti-corrosion solutions and quotations for a specific project, please feel free to contact us!

R&D Update | Test Progress of New Hot Melt Adhesive Heat Shrinkable Tape for Steel Pipes

R&D Update | Test Progress of New Hot Melt Adhesive Heat Shrinkable Tape for Steel Pipes

Recently, our company carried out iterative R&D on a hot melt adhesive heat shrinkable tape formulation dedicated to steel pipe surfaces. The new sample exhibits extremely high peel strength, exceeding the measurement range of the test equipment, so the equipment could not read precise test data. Manual peel testing confirmed: the adhesive layer bonds firmly to the steel pipe with no interfacial debonding; under external force, the heat shrinkable tape substrate was stretched and elongated, achieving substrate failure, which proves that the adhesive-steel bonding strength is superior to the substrate's own strength. The R&D team will continue to optimize the formulation and testing plan, refine product stability, and follow up with updated test results. YiHuiDe adheres to technological innovation and is committed to providing high-performance, reliable products for pipeline anti-corrosion. The test video is available below. Enjoy!
