Description
Technical field
The present invention relates to clamp facility technical field, in particular it relates to the Moveable high-pressure water-jet of a kind of sea pipe
Stream device.
Background technology
It is surrounded by cementitious coating on the outer surface of the submarine pipeline of submarine oil-transportation, gas pipeline and oil and gas multiphase flow and prevents
Rotten layer.It addition, crude oil, natural gas and water are walked the most in the duct, forming precipitation and dirt, these sink
Form sediment and dirt not only increases the resistance in fluid delivery process, obstruct fluid conveying, and corrode and destroy
Pipeline, makes pipeline cisco unity malfunction.To this end, usually need timing cleaning inside and outside pipeline, to ensure oil
Feed channel can be normal, safe work.
The cementitious coating being surrounded by currently for outside and the submarine pipeline cleaning of anticorrosive coat, the side generally used
Method has: Handheld high-voltage water law, it may be assumed that be carried out oil and gas pipes by diver's hand-held high-pressure water jet rifle.
But, owing to the recoil of high-pressure water jet rifle is bigger, diver's workload is bigger, it is difficult to meet long
The requirement of Time Continuous work.The internal washing of submarine pipeline uses Chemical cleaning mostly, and the method is first to oil
