Shanxi Bote groove clamp falls into two main categories including rigid type and flexible type, serving as core connection parts for fire protection pipeline systems. Made of ductile iron and coated with special red epoxy paint for anti-corrosion, this product complies with national fire standard GB5135.11 and holds complete 3C fire certification.
No welding work is required during installation. The groove clamp tightly locks steel pipes to realize fast assembly, which greatly improves construction safety and efficiency while bringing convenient maintenance access in later service cycles. It delivers outstanding sealing performance with a rated working pressure of 1.6MPa, covering full size range from DN65 to DN300.
As essential grooved pipe fittings, it matches all standard steel pipe Fittings and works perfectly with pipe couplings and mechanical pipe fittings to build complete grooved coupling fittings network for fire sprinkler projects.
Rigid groove clamp fixes pipeline position without displacement, while flexible groove clamp allows small axial displacement and angle compensation. Both types enrich the selection of grooved coupling fittings to satisfy various layout designs of mechanical pipe fittings.
Ductile iron base owns strong impact resistance and pressure bearing capacity. Uniform red epoxy coating blocks moisture and oxidation, long-term protecting steel pipe fittings in humid underground and indoor fire pipeline environments.
Only simple bolt tightening is needed to lock grooved pipe fittings together, removing fire hazards caused by welding operation. Construction speed is significantly higher than traditional welded pipe couplings for large-scale fire projects.
Matching high elastic rubber sealing ring achieves zero leakage under 1.6MPa working pressure. The clamping structure evenly distributes pressure across pipe joints, maintaining tight sealing for long-term running fire water pipelines.
Full specifications from DN65 to DN300 cover mainstream fire pipe diameters. All sizes are compatible with standard steel pipe fittings, forming complete sets of grooved pipe fittings and mechanical pipe fittings for one-stop procurement.
Manufactured following GB5135.11 standard and certified with 3C fire safety certificate. All inspection documents can be provided to pass fire department audit and project acceptance smoothly.
Main connection component for indoor fire water supply pipelines, widely used in residential, commercial and office building fire protection networks.
Large-diameter grooved pipe fittings DN150-DN300 fit large public venues with complex long-distance pipeline layout.
Red epoxy anti-corrosion coating adapts to damp underground environment, stable as long-term mechanical pipe fittings.
Welding-free assembly avoids open fire risks during construction inside flammable goods storage areas.
Flexible groove clamp absorbs pipeline thermal expansion deformation, protecting steel pipe fittings from cracking.
High pressure resistance of grooved coupling fittings meets frequent water pressure fluctuation in pump station main pipelines.
All premium groove clamps are manufactured strictly following GB5135.11 fire protection standard for grooved pipe fittings, and passed national compulsory 3C fire certification. Every batch of grooved coupling fittings undergoes full performance inspection before delivery:
Formal 3C certification certificate, factory test reports and production qualification documents can be provided for project acceptance, fire department audit and engineering bidding.
Customized service is available for fire engineering companies, pipeline distributors and large construction contractors:
