Hangzhou Shunhao Rubber Engineering Co., Ltd.'s products are highly regarded in the industry for their excellent performance. Features such as high temperature resistance, corrosion resistance, wear resistance, ease of construction, energy efficiency, and reliability, allowing them to withstand the harshest environments, are just some of the many excellent properties of Hangzhou Shunhao products. The company has participated in the drafting and writing of national standards including 《橡胶衬里》(Rubber Lining), 《工业设备及管道防腐蚀工程施工规范》(Construction Specifications for Corrosion Prevention Engineering of Industrial Equipment and Pipelines), 《烟气脱硫衬里》(Flue Gas Desulfurization Lining), and 《防腐蚀工培训教程》(Corrosion Prevention Worker Training Manual), and has obtained a Class A qualification in corrosion prevention construction.

　　Corrugated pipes primarily utilize the unique properties of rubber, such as high elasticity, high airtightness, resistance to media and weathering, and radiation resistance. They are made by using high-strength, cold and heat stable polyester fabric diagonally laminated and then high-pressure, high-temperature molded and cross-linked. The high internal density allows them to withstand high pressure, and they exhibit excellent elastic deformation.

　　Commonly used material types and applications: Seal materials must meet the requirements of sealing functionality. Due to the different media being sealed and the different operating conditions of the equipment, the sealing materials are required to have different adaptability.

The general requirements for sealing materials are:

1) The material is dense and prevents leakage of the medium;

2) It has appropriate mechanical strength and hardness;

3) Good compressibility and resilience, with small permanent deformation;

4) It does not soften or decompose at high temperatures, and does not harden or become brittle at low temperatures;

5) Good corrosion resistance, capable of long-term operation in acidic, alkaline, and oily media, with minimal changes in volume and hardness, and does not adhere to metal surfaces;

6) Low coefficient of friction and good wear resistance;

7) It has the flexibility to bond with the sealing surface;

8) Good aging resistance and durability;

9) Easy to process and manufacture, inexpensive, and readily available.
