Product & Service

The pipeline internal field joint coating robot is like a group of small trains connected in series, which could be functionally classified as tractors, shot blasting, vacuum recycling, anti-corrosion coating and inspection carriages.

The technology of Xi'an ShenLan Intelligent Machine Co., Ltd. strengthens the typical anti-corrosion method by performing shot blast cleaning, paint spraying and checking on the internal weld of the newly built pipeline.

Through wireless remote control, with a high-definition camera, the robot enters the pipeline accurately to locate the weld, then the joint area will be centrifugal blasted with mixture of steel grits and shots to a proper surface and prepare for the coating applicating, and the overlapping areas on both sides are pulled, and the weld and reserved area are anchored. The technology of blast helps adhesion of anti-corrosion coatings.

Pipe diameter: D=Φ273mm and above

Cleanliness: Sa 2.5, anchor pattern 40-80μm

Positioning accuracy: ±5mm

Climbing angle: ≤15°

Working distance: 500m one time

After blasting, the abrasive materials left on the internal pipe surface will be thoroughly recycled by vacuum recycling robot and no excessive residue will be left on the pipe internal surface.

Pipe diameter: D=Φ219mm and above

Positioning accuracy: ±5mm

Climbing angle: ≤15°

Working distance: 500m one time

The curing agent and the epoxy coating are respectively installed in the silo with heating function, and the operator accurately position the spraying robot at the weld seam by the real-time video image returned by the high-definition camera, and perform the coating operation according to the requirements of the coating manufacturer.
