The drill pipe is a steel pipe with a thread at the tail, which is used to connect the surface equipment of the drilling rig and the drilling equipment or bottom hole device at the bottom of the drilling. The purpose of the drill pipe is to carry drilling mud to the drill bit and raise, lower or rotate the bottom hole device together with the drill bit. The drill pipe must be able to withstand huge internal and external pressure, distortion, bending and vibration. In the process of oil and gas extraction and refining, drill pipe can be used many times.

The purpose of the drill pipe is to transport drilling mud to the drill bit andRaise, lower or rotate the bottom hole device together with the drill bit. Drill pipe must be able to withstand huge internalexternal pressure, twisting, bending and vibration. In the process of oil and gas extraction and refining, drill pipe can be moretimes of use.

So how to clean and maintain the joints of the drill pipe? Next we will talk about the followingSome notes:

1, hydraulic parts disassembly, cleaning should be in line with national standards in the purification room, if anyIt is best to charge the operating room to make the indoor pressure higher than the outdoor pressure to prevent atmospheric dust pollution.If limited by conditions, the operating room should also be isolated separately, generally not allowed to hydraulic parts assembly room andThe machining room or fitter room is in the same room, and it is absolutely forbidden to be in the open air, shed or utility room.Or disassemble and assemble hydraulic parts in the warehouse. When disassembling hydraulic parts, the operator should wear fiberWork clothes and work caps that are easy to fall off to prevent fibers, dust, hair, dander, etc. from falling into the liquid

The pressure system causes man-made pollution. Smoking and eating are strictly prohibited in the operating room.

2, hydraulic parts cleaning should be carried out on the special cleaning platform, if limited by conditions, but also to be sureTo ensure the cleanliness of the temporary workbench.

3, drill pipe cleaning fluid allows the use of kerosene, gasoline and hydraulic system work with oil brandthe same hydraulic oil.

4. The cleaned parts are not allowed to be wiped with cotton, hemp, silk and chemical fiber fabrics to prevent them from falling off.fiber pollution system. It is also not allowed to use a skin tiger to blow air to the component, if necessary, it can be used to clean dry.Dry compressed air to blow dry components.

5, drill pipe cleaning components are not allowed to be directly placed on the land, cement, floor, fitterThe table and the assembly workbench should be placed in a container with a lid and filled with clean hydraulic oil.

6, has been cleaned but temporarily not assembled components should be put into anti-rust oil preservation, wet groundAreas and seasons should pay special attention to rust prevention.
