Dredged steel pipe using submerged arc, the main role is mainly used to clean silt, mud, and other mixed debris steel pipe. The purpose is to excavate the harbor basin, approach channel, and so on, to fill land for the construction of a wharf, port area and port industrial zone, coastal urban land and recreational land, beach maintenance, water conservancy, and flood control, reservoir silt removal, water environment improvement and ecological restoration of rivers, lakes, and seas, construction, and landfill of various underwater pipeline and ditch, etc.

Dredged steel pipe is widely used in beaches, rivers, waterways, urban environmental protection, engineering construction, and other fields.

Mainly using steel pipe

Mainly spiral steel pipe, seamless steel pipe, and straight seam steel pipe.

The forming process of spiral steel pipe:

The steel plate should be uniform in deformation, and small in residual stress, and the surface should not be scratched, so the selection of steel plate made of spiral steel pipe should be careful, and surface should be uniform without scratches. The spiral steel pipe processed in the diameter and wall thickness size specification range has greater flexibility, especially in the production of high steel class thick wall pipe, especially medium and small diameter thick wall pipe, has the incomparable advantages of other processes, can meet the user in the spiral steel pipe specification more requirements. The diameter and size specification range of spiral steel pipe should be mastered flexibly, and it can be popularized and promoted by using its own good advantages and the wide needs of more users

Cangzhou shenlong pipe in professional dredge pipe manufacturers, we usually use straight seam submerged arc welding process or spiral submerged arc welding process to produce steel pipes, which generally are selected according to the different diameter of wall thickness, at the same time, we can according to project requirement, set length, and the welding flange and so on, ensure that the site of the project installation easy to use.

The dredged steel pipe of 1050*25mm 4500 meters sent to Dubai by our company adopts the straight-seam submerged arc welding process, and the flange is welded at the same time. Recently, the production has been delivered successively. We hope that more customers can visit our company and purchase.
