Product description

Grooved Connection Technology, also known as Clamp Connection Technology, has been widely adopted in domestic and international markets due to its advanced nature, gradually replacing traditional pipeline connection methods such as flanges and welding. It is not only technically mature and market-proven but also actively guided by national regulations and policies. This technology simplifies pipeline connections, making them faster, more convenient, and propelling pipeline engineering forward.

Customer challenge

Traditional Welding and Flange

Connections are rigid joints, which fail to address issues such as pipeline thermal expansion/contraction and settlement.

Traditional Flange Connections

Require large installation space, unsuitable for confined areas.

Traditional Welding/Flange Connections

Low efficiency, high costs, long cycles, and complex maintenance.

Traditional Welded Connections

Generate welding slag and fumes, demand high installation qualifications, prolong project timelines, and increase costs.

Traditional Threaded Connections

On-site threading is required, complicating construction.

Product function

Eco-Friendliness

Impact Resistance

Quick Installation

Vibration Absorption

Bolts and nuts feature trivalent chromium coating, ensuring environmental safety. On-site installation generates no welding slag or fume pollution.

High mechanical strength, strong pressure resistance, and excellent durability against physical impacts.

Disassembly, maintenance, and replacement of pipeline components are effortless. Particularly with our Quick-Install Series, installation speed is increased tenfold.

Pre-set pipe-end clearance efficiently addresses pipeline thermal expansion/contraction and compensates for pipeline settlement.

Value advantage

Economic Efficiency

The simplicity of grooved pipe fittings connection operations saves labor and time, resulting in strong economic benefits.
Construction Safety

Grooved pipe fittings connection technology requires only basic tools on-site, such as a cutting machine, grooving machine, and wrenches for tightening bolts. Construction organization is simplified, and no open flame treatment is required.
Easy Installation

The connection process for grooved pipe fittings is straightforward, requiring no specialized skills. Ordinary workers can operate it after brief training. The required installation space is minimal, allowing true wall- or corner-mounted installation. This significantly reduces operational complexity, saves floor space, and improves the aesthetic quality of pipeline installation.
Easy Maintenance

The system exhibits excellent stability and ease of maintenance. The grooved pipe fittings connection method features unique flexible characteristics, enabling the pipeline to resist vibration, contraction, and expansion. Compared to welding and flange connections, the stability of the pipeline system is enhanced, making it more adaptable to temperature variations. This protects pipeline valves and reduces stress-induced damage to structural components.
Corrosion Resistance

The surface of castings can undergo anti-corrosion treatments such as electrophoretic coating, powder coating, and hot-dip galvanizing.
