Description
Technical Field
The utility model relates to the field of damage detection of wellhead oil pipe components, in particular to a three-direction portable wellhead component damage detection device.
Background
In the long-term oil exploitation process, due to the existence of external and internal media, the outlet valve of wellhead equipment, a safety valve, a pipeline and the like are damaged by abrasion, corrosion, cracks and the like in different degrees, so that the bearing capacity is reduced, if the oil is not processed in time, the oil pipe can be leaked or even burst seriously, the serious production safety problem is caused, and the oil extraction cost is greatly increased. In order to prevent the occurrence of danger, the regular pipeline safety detection is important.
Detection methods for wellhead devices can be broadly divided into two categories: destructive testing and nondestructive testing. Since the destructive inspection method may cause damage to the inspected object, a nondestructive inspection method is generally used. Common nondestructive testing methods include magnetic particle testing, eddy current testing, penetrant testing, radiation testing, and ultrasonic testing. The magnetic powder detection and eddy current detection are mainly used for detecting the defects of the surface and the near surface of a detected workpiece; the penetration detection is generally only used for detecting the opening defects on the surface of a detected workpiece; x-rays and ultrasound can be used to detect defects inside and on the surface of the inspected workpiece; ultrasonic testing generally reflects damage indirectly through wall thickness measurements, but is not detectable in areas where the surface is intact and stress concentrations are severe.
Conventional X-ray generation devices generate a certain number of electrons by directly heating a helical tungsten filament. The high-voltage strong electric field is used in the vacuum space to make the electrons move at high speed to generate high-speed electron current, which impacts the anode target surface to generate X-ray. However, the continued high temperature gradually thins the wire, resulting in a slow weakening of the thermionic emission capability. Under the action of the high-voltage electric field, metal atoms or molecules formed by evaporation collide with high-speed electrons and a small amount of residual gas molecules to be ionized to form positive ions, and the positive ions impact the metal wire to enable the metal wire to be sputtered and even to be blown, so that the service life of the X-ray tube is shortened. And the volume is relatively large, the power consumption is large, and the portable type solar water heater is not suitable for carrying.
