Flange is a commonly used method of pipe connection, and there are some precautions to be taken during its installation process. The following will introduce several aspects that need special attention during flange installation.
Firstly, the selection and inspection of flanges. Before using flanges, it is necessary to choose the appropriate flange model and size based on the specific work scenario and requirements. After selection, it is necessary to inspect the flange to ensure that its appearance is free of obvious defects and damage, and the inner hole is smooth and free of burrs.
Next is the preparation of the installation environment for the flange. Before installing the flange, it is necessary to clean the installation environment to ensure that it is clean, tidy, and free of debris. At the same time, it is necessary to check whether the insulation layer of the pipeline is normal and whether there is any structural looseness or damage.
Next is the installation method of the flange. Firstly, it is necessary to place the flange in the correct position to ensure alignment with the connecting ports of adjacent pipelines. Then, use a wrench or other tool to gradually tighten the bolts, forming a tight connection between the flange and adjacent pipes. It should be noted that when tightening the bolts, the force should be evenly applied to avoid deviation or excessive tightness causing leakage.
During the installation of the flange, it is also necessary to pay attention to the size fit. The connection size of the flange should be consistent to ensure good sealing performance. If the size does not match, a gasket can be used for compensation, but the compensation amount should not be too large to avoid affecting the sealing effect.
In addition, attention should also be paid to the selection and installation of sealing gaskets when installing flanges. Sealing gaskets are usually made of materials such as rubber gaskets, iron sheets, or PTFE gaskets, and suitable sealing gaskets should be selected according to the specific working environment. During installation, the sealing gasket should be carefully placed on the flange connection surface to ensure that there is no looseness, damage, or overlap.
After the flange installation is completed, sealing performance testing is also required. Water pressure test or airtightness test can be used to ensure that there is no leakage at the flange connection. During testing, it is necessary to gradually increase the pressure and observe for any leaks or leaks to ensure installation quality.
Finally, acceptance and recording are required after the flange installation is completed. During acceptance, the flange connection should be checked for firmness and good sealing performance. At the same time, it is necessary to record the relevant information about flange installation, including flange model, size, installation date, etc., for future maintenance and management use.
In summary, the precautions to be taken during flange installation include selection and inspection, preparation of installation environment, installation method, size matching, selection and installation of sealing gasket, sealing performance testing, acceptance and recording, etc. Only by strictly following the standard operation can the safe and reliable use of flanges be ensured.
