The continuous innovation of the building materials industry has led to the emergence of many new materials. These new materials have optimized certain properties on the basis of previous materials and better adapted to the public requirements of modern home life. For example, in recent years, the popular glass wool pipe has engineering features that traditional pipe fittings do not have, thereby occupying a certain building material market. In engineering projects, Glass Wool Pipe is usually used for the insulation shell of refrigeration, hot air or hot water pipes. Ordinary glass wool pipes also have a certain temperature range. After this range, the work safety of glass wool pipes cannot be fully achieved. Assurance, the pipe itself may burst. In addition, for outdoor working environments, glass wool pipes also have environmental characteristics, can be waterproof and anticorrosive, and will not mold like ordinary pipe fittings. With these features, engineering and technical
