API 5L PSL2 concrete weight coated pipe, CWC pipe anode

Oil and gas pipeline construction is in the peak period, long-distance and large-diameter pipeline will inevitably pass through rivers, lakes, beaches, wetlands, marshes and other special sections in the construction process. In the process of laying and construction of underwater long-distance pipeline, due to the buoyancy and hydrodynamic force, only relying on the gravity of the pipeline itself, can not maintain the settlement depth and stability of the pipeline. Effective and economic measures should be taken to stabilize the pipeline in the trench. Concrete weight coating (CWC) is one of the good methods.

The main API 5L PSL2 concrete weight coated pipe, CWC pipe we supply are as below:

The main function of concrete weight coating (CWC) applied to steel pipe is to provide negative buoyancy for steel pipe, to ensure the stability of steel pipe under water, and to provide mechanical protection for steel pipe under water.

The API 5L PSL2 concrete weight coated pipe, CWC pipe can be immersed in a certain depth of the sea bottom, laid in the swamp, rivers and lakes.
