Main Applications
1Chemical/Petrochemical Industry: Corrosive, temporary, or low-pressure pipelines.
Food/Pharmaceutical Industry: Hygienic clean pipelines for easy cleaning and maintenance.
Low-Pressure Gas Systems: Household gas pipelines and small equipment connections (to avoid welding risks)
Water Supply and Drainage: Civil building pipelines (e.g., galvanized pipes) and low-pressure pipelines in wastewater treatment.
Marine/Ocean Engineering: Internal pipelines requiring frequent maintenance or temporary pipelines.
Power Industry Auxiliary Systems: Non-high-temperature and non-high-pressure pipelines for compressed air or industrial water.
Special Environments: Fire-prohibited zones, low/non-high temperatures (-45°C~260°C), and renovation of old pipelines.
Advantages
1. Convenient for installation and maintenance without welding.
2. Suitable for fire-prohibited scenarios (e.g., flammable and explosive areas).
3. Avoids damage to anti-corrosion coatings or clean pipelines caused by welding.
4. Ideal for temporary or detachable pipeline connections, reducing maintenance costs.
5. Strong applicability to materials with poor weldability (e.g., some alloy steels).
