Connection Common connection methods include welding, flange connection, and clamp connection. Welding connection is firm and reliable, and can form a continuous sealing structure to effectively prevent air leakage. It is suitable for ventilation systems with extremely high requirements for sealing, such as clean room ventilation ducts. Flange connection is easy to install and disassemble, convenient for later maintenance and repair, and can withstand a certain amount of pressure. It is often used in industrial ventilation ducts. Clamp connection is easy and quick to install, with high connection strength and good sealing. It has obvious advantages in temporary ventilation projects, small ventilation renovation projects and other projects with high requirements for installation efficiency.
Basic stainless steel material Commonly used stainless steel grades include 304 and 316. 304 stainless steel contains 18% chromium and 8% nickel, and has good corrosion resistance and oxidation resistance. It can be stably used in general industrial and civil environments, effectively resisting the erosion of humid air and common acid and alkali substances, preventing pipelines from rusting and corrosion, and extending service life. 316 stainless steel has excellent performance in pitting and chloride ion corrosion resistance due to the addition of molybdenum. It is suitable for coastal areas, chemical plants and other areas with high chloride ion concentration and harsh corrosive environment to ensure the long-term reliable operation of ventilation ducts.
