Description
Technical field
The present invention relates to clamping equipment technical fields, and in particular, to a kind of Moveable high-pressure water jet device of sea pipe.
Background technique
Cementitious coating and erosion resistant coating are surrounded by the outer surface of the submarine pipeline of submarine oil-transportation, gas pipeline and oil and gas multiphase flow.
In addition, crude oil, natural gas and water are usually walked in the duct, precipitating and dirt are formed, these precipitatings and dirt not only increase
Resistance in fluid delivery process obstructs fluid conveying, and corrodes and destroy pipeline, makes pipeline cisco unity malfunction.For this purpose,
It usually needs to periodically being cleared up inside and outside pipeline, to guarantee that oil-gas pipeline being capable of normal, safety work.
Currently, clearing up for the submarine pipeline of cementitious coating and erosion resistant coating that outside is surrounded by, the method generallyd use has: hand
Hold formula High-Pressure Water method, it may be assumed that high-pressure water jet rifle is held by diver and is cleaned to oil-gas pipeline.But due to high-pressure water shot
The recoil for flowing rifle is bigger, and diver's workload is larger, it is difficult to meet the requirement of long time continuous working.Submarine pipeline
Internal washing mostly uses greatly chemical cleaning, and this method first carries out alkali cleaning to oil pipe, and then pickling later carries out at neutralization oil pipe
Reason.The oil pipe blocked must be pre-processed first with drilling rod, just can guarantee that washing and cleaning operation is normally carried out.Chemical cleaning method
The influence of simple process but its cleaning quality vulnerable to the factors such as oil pipe inside and outside wall dirt and artificial, environment.
To solve the above-mentioned problems, it is managed using Cleaning by High Pressure Water Jet sea.Cleaning by High Pressure Water Jet is easy to operate, high-efficient,
Hard scale, dirt hard to tolerate can be removed.With free from environmental pollution compared with chemical cleaning, do not corrode cleaning object, cleaning efficiency is high and section
