Description

Technical Field

[0001] This application relates to the field of plastic-coated steel pipe installation technology, and more specifically, to a connection device for plastic-coated steel pipes for water supply. Background Technology

[0002] In municipal engineering, plastic-coated steel pipes are commonly used for water supply and drainage pipelines. Several plastic-coated steel pipes are connected by insertion through underground burial to complete the water supply and drainage pipeline construction project. Adjacent plastic-coated steel pipes are typically connected using clamps for restraint. However, with long-term use, plastic-coated steel pipes are prone to leakage due to geological conditions and clamp loosening. Reinforcement and anti-loosening measures are necessary. Furthermore, connecting two plastic-coated steel pipes requires manual labor, which is labor-intensive. Therefore, we propose a connection device for plastic-coated steel pipes used in water supply.
