Embodiment Construction

[0011] Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

[0012] figure 1 Shown is the block diagram of the remanufacturing method flow of the waste oil pipe of the present invention.

[0013] According to an embodiment of the present invention, the remanufacturing method of waste oil pipe is:

[0014] (1) Cut off the upsetting parts at both ends of the scrap oil pipes that have lost their service ability, leaving only the middle part;

[0015] (2) Heating the tubing to remove the dirt, squeezing the heated tubing to repair pits on the surface of the tubing, and removing stress from the fatigued tubing to prepare for the next step of processing;

[0016] (3) Straighten the oil pipe to make it meet the standard requirements. The function of straightening is to prevent the oil pipe from being unable to be hot-rolled and restored in the subsequent process;

[0017] (4) Carry out hot rolling reductio...

Abstract

The invention relates to a remanufacturing method for waste oil tubes. The biggest characteristic of the remanufacturing method for the waste oil tubes is to upset the head of each oil tube, and then perform quenching and tempering treatment for the whole oil tube to ensure the strength uniformity of the whole oil tube. The effects of recycling the resources, saving the energy and reducing the cost can be realized through recycling the waste oil tubes, and thus the cyclic utilization problem of the waste oil tubes can be effectively solved by processing.

Description

technical field [0001] The invention relates to a remanufacturing method of oil pipes, in particular to a remanufacturing method of reproducing waste oil pipes. Background technique [0002] The biggest feature of the existing oil pipe production method is to upset the head of the oil pipe, and then carry out quenching and tempering treatment on the whole oil pipe, so as to ensure that the whole oil pipe can have a uniform strength, thereby increasing the strength of the oil pipe. service life. [0003] In addition, major domestic oil fields regularly eliminate a large number of oil pipes on a regular basis every year. If these abandoned oil pipes can be processed through a set of processing methods to eliminate metal fatigue and restore their metallographic structure, this is undoubtedly a way to realize waste utilization. An effective way to save energy and reduce consumption. At present, the repair of the oil pipe is limited to cleaning the scrapped oil pipe for dirt, a...
