During the installation of building-related pipelines, it is sometimes unavoidable to pass pipelines through walls. In such cases, wall bushings must be used at the relevant locations to protect the pipelines from the pressure of the building structure. However, during the lowering operation, a great deal of technical knowledge and attention to detail are required. Specifically, the following precautions should be observed during this process.

1. Pay attention to installation preparation

Before the formal lowering and installation, thorough inspection work must be carried out to ensure there are no issues before proceeding to the next step. As introduced by wall bushing manufacturers, check whether each bushing and pipeline is unobstructed, as well as the quality of the bushing body itself, to avoid any bending or damage. Also, carefully clean the threads and apply lubricating oil, and check to ensure that the relevant parts of the bushing remain unobstructed.

2. Pay attention to proper fixation during lifting and ensure safety

When lifting the bushing, always check the slings. Wall bushing manufacturers emphasize that the slings must be securely fastened. For bushings with a larger diameter, an additional rope should be tied at the end to provide greater stability. Trustworthy wall bushing manufacturers also recommend using a guide rope to reduce the swinging effect of the bushing. Then, the signal person should gesture or signal to the crane operator for the next step.

3. Pay attention to operational details at the wellhead

Reliable wall bushing manufacturers remind that tools must be inspected beforehand to ensure they are flexible, functional, and of good quality. During operation, measures must be taken to ensure that no objects fall into the bushing or the well. All workers should coordinate with each other and focus on each operation to ensure safety and efficient, one-time success.

The above are several aspects to note during the lowering operation of wall bushings. In addition, attention should be paid to on-site safety procedures. As introduced by wall bushing manufacturers, for example, when using a grinder to cut pipes, do not wear gloves; when using gas welding, oxygen cylinders and other tools are required, and contact with open flames must be avoided. All tools and materials should be securely placed to prevent them from falling and causing injury.
