A fixed limit expander is a device used to restrict the movement of pipes, valves, or other equipment within a certain range. It usually consists of a holder and a telescopic rod, which can be adapted to different pipe or equipment sizes by adjusting the length of the telescopic rod. Fixed limit expanders are widely used in various industrial fields, such as petroleum, chemical industry, electric power, etc., to fix pipelines, valves and other equipment to prevent accidental movement or vibration.
Fixed limit retractors should be flexible enough to accommodate different pipe or equipment sizes and shapes, as well as to different installation environments and conditions. The fixed limit retractor should be safe and reliable, and will not cause excessive stress or vibration to the pipeline or equipment, and will not cause harm to the human body.
The fixed limit retractor is an important industrial equipment accessory, and its design should be reliable, adaptable, durable, easy to install and safe. When selecting a fixed limit retractor, factors such as the application, the size and weight of the pipe or equipment, environmental factors, installation and maintenance costs, brand and quality need to be considered.
