Program overview

Large-diameter steel pipe grooved connection solutions

Meide Group's Self-Developed Large-Diameter Flexible Couplings. Meide Group has independently developed large-diameter flexible couplings, achieving flexible connections for large-diameter steel pipes in water conservancy projects. This innovation completely resolves the anti-corrosion challenges associated with welded steel pipes, extending their service life from 20-30 years to over 50 years. These joints ensure the safety of pipeline water quality, reduce pipeline leakage rates, and minimize the scope of operational safety incidents. Additionally, the large-diameter grooved connections enable quick and easy installation, reducing construction difficulty and improving installation efficiency. This advancement is conducive to promoting high-quality development in pipeline connections within the water conservancy industry.

Customer Challenges

Enhancing Pipeline Durability

Traditional welded connections for steel pipes often fail to provide complete anti-corrosion protection at the joints, which reduces the overall service life of the pipeline network.

Ensuring the Safe Operation of Pipeline Networks

The rigid connections of traditional steel pipe joints are ineffective in preventing unforeseen geological issues, which can lead to pipe bursts and significant water resource wastage. Additionally, the requirement for open-flame operations introduces numerous potential safety hazards.

Reducing Construction Time and Costs

Traditional steel pipe connection methods require specialized personnel for installation, increasing construction timelines and project risks. This also leads to higher labor costs and additional investment in equipment.

Buried Grooved Connection

Steel pipes connected using flexible grooved couplings exhibit sufficient tensile strength, with joints capable of large angles and significant extension. The installation is simple and fast, suitable for a wide range of pressure conditions. It adapts to complex geological environments such as weak foundations, subsidence areas, seismic zones, and steep slopes, significantly extending the service life of pipelines and reducing maintenance and replacement costs.

Overhead Grooved Connections

Steel pipes connected with rigid grooved couplings feature joints with minimal compensation capacity, replacing traditional rigid connection methods such as welding or flanged joints. This solution effectively addresses stresses caused by temperature fluctuations, installation forces, and additional operational loads. By fundamentally resolving the limitations of rigid pipe connections, it eliminates the need for sliding supports, enhances safety, and simplifies installation.

Flexible Couplings for Valve and Pipeline Connections – Replacing Expansion Joints

Flexible couplings are used to connect valves or pipelines, offering a cost-effective and maintenance-free solution. They provide vibration damping, ensure leak-free operation, and enhance safety. Additionally, they significantly improve installation efficiency, making them an ideal alternative to traditional expansion joints.
