What should be paid attention to when stainless steel duct can be installed in scientific research laboratory project?

Attention should be paid to the following items when installing stainless steel air ducts in scientific research laboratory project:

I. Design and Planning Stage

Air flow and pressure demand

Accurately calculate the air flow and pressure required by the laboratory to determine the size of the air duct and the type selection of the fan. Different experimental equipment and operations may have different requirements for air flow and pressure.

Considering the future expansion needs of the laboratory, a certain air duct capacity is reserved.

Layout and trend

Reasonably plan the layout and direction of the air duct, minimize the length of the air duct and the number of elbows, so as to reduce air resistance and noise.

Avoid conflicts between air ducts and other pipelines and equipment, and ensure sufficient installation space.

Considering the convenience of air duct maintenance and cleaning, the maintenance port and cleaning port are set.

Material selection

Choose high-quality stainless steel material to ensure that the air duct has good corrosion resistance, sealing and strength. Common stainless steel materials are 304 and 316, etc., which are selected according to the laboratory environment and use requirements.

Check the quality certificate of stainless steel air duct to ensure that the material meets the relevant standards.

Second, the installation and construction stage

preliminary work for construction

Clean and tidy the construction site to ensure that the installation area is clean and tidy.

Check the quality of air ducts and fittings, and replace them in time if they are damaged or deformed.

Prepare tools and equipment needed for installation, such as welding machine, wrench, screwdriver, etc.

Duct connection

Adopt appropriate connection methods, such as welding and flange connection. When welding, the weld quality should be guaranteed to avoid defects such as porosity and cracks. When connecting flanges, ensure that the flanges are well sealed and the bolts are tightened evenly.

For long air ducts, supports and hangers should be set to ensure the stability of the air ducts. The spacing between supports and hangers shall meet the design requirements.

Sealing treatment

Seal the joints and interfaces of air ducts to prevent air leakage. Sealants, sealing strips and other materials can be used for sealing.

Check the airtightness of the air duct, which can be detected by light leakage method or air leakage test.

Cleaning and disinfection

After installation, clean and disinfect the air duct to remove dust, sundries and bacteria in the air duct. Professional cleaning equipment and disinfectants can be used for treatment.

After cleaning and disinfection, the air duct shall be sealed and preserved to prevent re-pollution.

Third, the debugging and acceptance stage

system debug

After the installation, debug the air duct system and check whether the operation, air flow and pressure of the fan meet the design requirements.

Adjust the valve and tuyere of the air duct to make the air distribution uniform and meet the needs of the laboratory.

acceptance standard

Carry out acceptance inspection according to relevant standards and specifications, and check whether the installation quality, sealing performance and cleanliness of the air duct meet the requirements.

After the acceptance, issue an acceptance report and file the relevant information.

In a word, the installation of stainless steel air duct in scientific research laboratory project needs to be carried out in strict accordance with the design requirements and construction specifications, so as to ensure that the quality and performance of the air duct system can meet the needs of the laboratory. At the same time, attention should be paid to safe construction to avoid accidents.
