Product details

Premium Groove Clamp for Seamless Pipe Fittings

Product Overview

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.

Product Features & Advantages

1. Dual Types for Different Pipeline Demands

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.

2. Ductile Iron Body with Fireproof Epoxy Coating

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.

3. Welding-Free Fast On-site Installation

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.

4. Excellent Sealing & Stable Pressure Resistance

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.

5. Complete Size Range for Full Pipeline Matching

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.

6. Standard Fire Certification for Engineering Acceptance

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.

Step-by-Step Installation Guide

Process groove on both ends of steel pipe fittings according to standard size, clean burr, dust and rust on the groove surface.
Place the sealing rubber ring on the pipe end, ensure the ring sits evenly without distortion or offset.
Align two grooved pipe fittings, cover the rubber ring with groove clamp and align the clamp inner ribs with pipe grooves.
Install bolts and nuts symmetrically, tighten nuts alternately to guarantee uniform clamping force around the whole circle.
Check the clearance between clamp and pipe surface to confirm no partial extrusion of rubber ring.
Carry out hydraulic pressure test after finishing all grooved coupling fittings connection to verify joint sealing without water leakage.

Application Scenarios

Building Fire Sprinkler Systems

Main connection component for indoor fire water supply pipelines, widely used in residential, commercial and office building fire protection networks.

Shopping Mall & Stadium Fire Projects

Large-diameter grooved pipe fittings DN150-DN300 fit large public venues with complex long-distance pipeline layout.

Underground Garage Fire Pipeline

Red epoxy anti-corrosion coating adapts to damp underground environment, stable as long-term mechanical pipe fittings.

Factory & Warehouse Fire Protection

Welding-free assembly avoids open fire risks during construction inside flammable goods storage areas.

Underground Comprehensive Pipe Gallery

Flexible groove clamp absorbs pipeline thermal expansion deformation, protecting steel pipe fittings from cracking.

Fire Pump Room Pipeline Connection

High pressure resistance of grooved coupling fittings meets frequent water pressure fluctuation in pump station main pipelines.

Core Benefits for Buyers
