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 harbor basin, approach channel, and so on, to fill land for construction of 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 beach, river, waterway, urban environmental protection, engineering construction and other fields.

Mainly using steel pipe

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

When selecting dredging equipment, we should consider:

(1) hydrologic and meteorological conditions such as wind, wave, flow rate and fog level in the construction area;

(2) Natural conditions such as topography, water depth and soil quality of dredged river reach or water area;

(3) The basic excavation method that can be selected is longitudinal excavation method; The chain bucket dredger should be excavated against the current, while the bucket and grab dredger should be excavated along the current. When the thickness of the mud layer exceeds the thickness of the dredger at a time, the method of layered excavation should be adopted. When the layer is layered, the upper layer should be thick and the base layer should be thin. When the width of the trench is large, the method of slicing excavation can be adopted. When the storm, flow rate, fog level exceeds the rule value, the operation should be stopped.

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 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.
