Selection & Installation Guide for Light-duty & Heavy-duty Plastic Pipe Clamps

During the installation of fluid pipelines, pipe clamps are not merely fasteners; they also directly affect the system stability, vibration control, leakage risk and service life.

Today, from an engineering perspective, let us systematically explore the professional pipe clamp solutions of Shenzhen Wofly Technology, to help your equipment operate more safely and efficiently.

Selection of Light-duty and Heavy-duty Plastic Pipe Clamps

The selection of light-duty and heavy-duty plastic pipe clamps should be based on a comprehensive consideration of pipe size, pressure, application scenarios and environmental factors.

Specific recommendations are as follows:

（1）Pipe Size

Light-duty pipe clamps: Suitable for small-caliber pipes, usually with a diameter range of φ6–φ42mm.

Heavy-duty pipe clamps: Suitable for large-caliber pipes, generally with a diameter of φ63.5mm and above.

（2）Pressure Rating

Light-duty pipe clamps: Applicable to low-pressure systems, such as ordinary electrical circuits and civil water supply and drainage pipelines, with low pressure-bearing capacity.

Heavy-duty pipe clamps: Applicable to high-pressure and high mechanical stress systems, such as industrial steam pipelines and hydraulic system pipelines, which can withstand high pressure and impact forces.

（3）Environmental Conditions：

Light-duty pipe clamps: Suitable for environments with small temperature changes, no severe vibration or impact.

Heavy-duty pipe clamps: Applicable to environments with high temperature, low temperature, high humidity or frequent vibration, such as outdoor areas, underground engineering and near mechanical equipment.

Summary: If the pipe size is small, pressure is low and application scenario is simple (e.g., indoor electrical wiring), light-duty plastic pipe clamps are preferred. If the pipe size is large, pressure is high and environment is complex (e.g., industrial pipelines and buried pipelines), heavy-duty plastic pipe clamps should be selected.

For actual selection, it is recommended to refer to the product specifications and technical parameters of pipe clamps, or consult professional suppliers.

How to Install Pipe Clamps

Before assembling on the welding plate, to better determine the orientation of the clamp, it is recommended to mark the fixing positions on the lower half of the clamping plate first, then perform welding, and then mount the pipeline to be fixed. Next, place the other half of the pipe clamp body and the cover plate, and tighten them with screws. Never directly weld the base plate with the pipe clamp already installed.

For installation on the ground guide rail: the guide rail can be welded to the base or fixed with screws. Then push the guide rail nut onto the rail and rotate it 90 degrees. Insert the lower half of the pipe clamp into the nut and place it on the pipe to be fixed. After that, fix the upper half of the pipe clamp and the cover plate, and secure them with screws.

For folded assemblies: the guide rail can be welded to the base or fixed with screws. First install the upper and lower halves of the pipe clamp, place the pipe to be fixed on the upper half of the clamp, then fasten the upper half with screws, and prevent it from rotating by means of the anti-loosening cover plate.
