It is not only corrosion-resistant, heat-insulating, high-pressure and impact-resistant in physical use, but also simple and convenient in the installation and transfer process, and easy to operate during later maintenance. The purpose is to solve the problem and improve the practical value through this technology. Utility Model Content
