Rigid Coupling

In pipeline engineering, rigid clamp is a commonly used connection component, which is used to fix the pipeline in the appropriate position to prevent the pipeline from moving or leaking. Rigid clamp is suitable for pipelines that need to be fixed in a fixed position, such as pipelines for conveying gas and liquid. Rigid clamp has the advantages of simple structure, easy installation, not easy to deform, and strong corrosion resistance. But its disadvantage is that it is not adapted to the thermal expansion and contraction of the pipeline, which can easily lead to pipeline rupture or clamp loosening. Rigid clamp is a rigid connection component, consisting of two metal plates, which fix the pipeline in the appropriate position by bolts and nuts. Rigid clamp is usually made of ductile iron, carbon steel, stainless steel and other materials, with high strength and corrosion resistance. The pipeline system with rigid clamp joint is in a rigid state, that is, the pipe cannot produce axial and radial displacement, and the system is not flexible. After the pipe clamp is clamped, it can form a rigid whole with the steel pipe. When the span of the hanger is large, the pipeline relies on its own rigid support to connect. This kind of pipe fitting is mostly suitable for the connection between riser and general pipeline system. Rigid clamps are commonly used connection parts in pipeline engineering. Each type of clamp has its own unique characteristics and application scenarios. When choosing a clamp, we need to choose the appropriate clamp type based on factors such as the type of pipeline, the use environment, thermal expansion and contraction, etc. to ensure the stability and safety of the pipeline.
