I. Product Function
1. Special fasteners for pipe fixing, used together with pressure plates and nuts to firmly secure various steel pipes onto supports, steel structures, and wall bases, limiting pipe displacement and reducing vibration and shaking;
2. Fixing accessories for water supply and drainage, chemical engineering, desulfurization, seawater desalination, marine composite pipelines, and stainless steel pipe supports;
3. Supporting and positioning components for photovoltaic supports, steel structure workshops, municipal pipe galleries, and large storage tank pipelines;
4. Suitable for hot and cold fluid conveying pipelines, and applicable to pipe clamping installation in multiple environments such as buried pipelines, outdoor sites, and ship cabins.

III. Material Application Scenarios
1. Q235B galvanized carbon steel type: suitable for indoor dry steel structure workshops and conventional water supply and drainage pipelines, offering high cost performance;
2. 304 stainless steel: suitable for outdoor exposed environments, freshwater transportation, and non-corrosive municipal pipelines;
3. 316L stainless steel: suitable for coastal factory areas, marine seawater pipelines, and desulfurization pipelines containing saline corrosive media.
IV. Product Advantages
1. The arc-bent structure fits the outer wall of the pipe, ensuring uniform force distribution without squeezing or damaging the anti-corrosion layer or lined composite pipe wall;
2. Complete threads at both ends allow flexible adjustment of clamping tightness when used with pressure plates, making installation and removal convenient;
3. Stainless steel material resists salt spray, acid, and alkali corrosion, making it suitable for complete use with composite anti-corrosion pipelines without the risk of galvanic corrosion;
4. Specifications cover the full range of pipe materials, including straight seam pipes, seamless pipes, lined pipes, and overlay-welded composite pipes;
5. Strong vibration resistance effectively prevents pipe slippage during long-term operation and reduces hidden risks of leakage at pipeline welds and flanges.
