Description
Technical field
The present invention relates to the thread lubricating grease smearing method in petroleum industry tubing repair technique and equipment, particularly oil pipe
The automatic smearing method of thread lubricating grease and its automatic applicator system, it is oil pipe before the pressure testing process of tubing repair technique
External screw thread and the internal thread of tubing coupling smear stop-leak compound automatically, improve operating efficiency.
Background technology
According to standard, in tubing repair technique, hydrostatic pressure testing is one of its necessary process.Tried at present using upper button
Press is that oil pipe carries out pressure testing operation, using the mode of threaded connection, during pressure testing, to avoid causing tubing round thread
Abrasion, one layer of lubricant grease or seal grease are smeared typically before pressure testing, play a part of protecting screw thread and to tubing seal,
To realize the pressure testing operation of higher efficiency.
But differ because pressure testing oil pipe has length, the reason such as specification difference, screw position difference, current each tubing repair
By the way of manually smearing, its existing subject matter has unit：
（1）Work situation is poor, and because being that lubricating grease is smeared before pressure testing, smearing work need to be carried out in higher-pressure region, serious height be present
Weigh the unsafe factors such as people, mechanical wounding wounded；
（2）Operating efficiency is low, and this work is engaged in one post of special setting, to reduce labor intensity, takes the side of operated in turn
Formula, cause the waste of human resources；
（3）Lubricant grease is smeared and is not easy to grasp, and it is excessive to often result in applying amount, and grease drippage is serious, not only increases and is produced into
Originally it is filthy, to also result in working environment, is unfavorable for field management.
