Dehe Technology’s liquefied gas cargo containment system polyurethane foam material passed CCS certification

Recently, the polyurethane foam products of Dehe Technology Group Co., Ltd. have officially passed the certification of China Classification Society. On the morning of August 3, the certification ceremony was held at the headquarters of Dehe Technology. This is also the first factory approval certificate issued by China Classification Society (CCS) Shanghai Branch for the polyurethane foam insulation material of the bulk transport liquefied gas carrier cargo containment system produced by Dehe Technology, fully promoting the supply of liquefied natural gas (LNG) ships Chain localization construction.

Established in 2001, Dehe Technology Group Co., Ltd. is one of the early foam glass manufacturers in China. After development, Dehe Technology has grown into a well-known overall solution provider for thermal insulation and energy-saving projects in China, focusing on R&D, production, sales and installation services of high-performance thermal insulation and energy-saving materials. The company's foam glass, rigid polyurethane, moisture-proof sealing auxiliary materials, pipe supports and hangers and other supporting materials are widely used in petrochemical, liquefied natural gas (LNG), liquefied petroleum gas (LPG), liquid hydrogen (LH2) , Coal chemical industry, air separation, urban construction, rail transit and other industries in the field of thermal insulation and energy saving of various storage tanks, pipelines and equipment. It has the first-class qualification for professional contracting of waterproof, anti-corrosion and thermal insulation projects, and has the ability to supply and install all-round services for thermal insulation and energy-saving engineering materials.

The company now has production bases in Jiaxing, Jiangsu, Yancheng, Nantong, and Xuancheng, Anhui; Jiangsu Dehe Thermal Insulation Technology Co., Ltd., Anhui Dehe Thermal Insulation Technology Co., Ltd., Zhejiang Dehe Import and Export Co., Ltd., Jiaxing Jiade Thermal Insulation Engineering Co., Ltd. Company and other subsidiaries. Dehe Technology is currently one of the top high-quality foam glass manufacturers in the world. The company's main product foam glass meets the American ASTM and European Union EN standards. Won the title of "New Generation Foam Glass Technology and Equipment Production Demonstration Line" in the industry, and can realize "personalized customization" of product technical indicators. The company's 15,000-ton polyurethane cryogenic composite material production base and R&D base project settled in Jiaxing, Zhejiang. It mainly produces composite thermal insulation materials for LNG storage and transportation. The provincial manufacturing industry's first (set) product engineering research project", the company's "LNG Marine High-end Polyurethane Cryogenic Composite Material Localization Substitution Project" was selected as the key research plan project of Jiaxing City in 2022.

The company's headquarters has a new material research institute and R&D center, and Beijing, Shanghai and Jiangsu bases have R&D branches. They are participating units in the compilation of foam glass international standards, industry standards and technical regulations of some provinces and cities. With advanced technology and innovative spirit, The company has successively won honors such as recommended products for petrochemical thermal insulation projects, product quality leader enterprises, first prizes in thermal insulation innovation competitions, and technological innovation demonstration enterprises in the petrochemical industry.

The company particularly focuses on the research and application of cutting-edge technologies in the field of thermal insulation and energy saving, especially in the field of low-temperature and ultra-low temperature thermal insulation storage and transportation application equipment. The company won the title of "Invisible Champion" Enterprise in Zhejiang Province in 2020, and a series of honorary titles such as "2021 Xiuzhou District Mayor Quality Award". Jiangsu Dehe, a subsidiary of the company, is a national high-tech enterprise, and was selected by the Ministry of Industry and Information Technology of the People's Republic of China in September 2021 as the third batch of specialized, special and new "little giant" enterprises.

As a research and development, engineering system solution and construction supplier of liquefied gas (LPG/LEG/LNG) cryogenic thermal insulation materials, Dehe Technology has introduced advanced polyurethane foam automatic production lines, online non-destructive testing equipment, laboratory ultra-low temperature (-170 ℃ ) Thermal conductivity testing equipment and quality control testing equipment. It has been verified by the approval test that the product has excellent cryogenic insulation performance (low thermal conductivity at -165°C) and excellent physical properties, and is a demonstration product for localized replacement of thermal insulation materials for LNG ship cargo containment systems.

With the opportunity of the country's green transformation and development, my country's shipbuilding industry has entered the fast lane of green, low-carbon and energy-saving development. The Shanghai branch explores an efficient accreditation inspection model, and fully promotes the enterprise's product development and accreditation work with the "production, research, inspection and application" model. The passing of the China Classification Society certification indicates that the design and manufacture of related products of Dehe Technology Group has the ability to provide supporting products and services for ships, and provides a guarantee for the company to develop the ship heat insulation and cold preservation market.
