Description
Technical field:
The utility model relates to a kind of tubing and casing detecting instrument, is specifically related to a kind of wear rib preventing tubing and casing galled spots when electromagnetic test.
Background technology:
In department's probings such as petroleum gas, geological and mineral, salt industry and exploitation, the special-purpose steel iron pipe materials such as a large amount of use drill collar, drilling rod, sleeve pipe, oil pipe, tracheae, the administrative authority of above-mentioned material needs often to carry out defect detecting test Timeliness coverage hidden danger to these tubing, produce to guarantee safety probing and to recover the oil, steel pipe's production producer, in manufacture tubing, also need to carry out wound to pipe material product split and detect, to guarantee tubing outgoing.Detecting in the past to oil special-purpose steel iron pipe material, generally Special electromagnetic ultrasonic flaw-detecting machine is all used to detect a flaw, but EMUS detection process can produce wearing and tearing to steel tube surface, this is generally running into of existing steel pipe's production enterprise and scabrous technical barrier, and domestic and international each sleeve in oil field manufacturing enterprise is all subject to the puzzlement of this problem.Along with high pressure injection adopt, the application of the various well stimulation such as UHV (ultra-high voltage) pressure break and the reason such as the growth of oil-field development time, mud stone water suction creep, rock stratum slip, sand production in oil, the resurrection of oilfield development process interrupting layer, perforation, earthquake, oil reservoir compacting, if defective casing wear in oil field can aggravate, cause serious consequence.Electromagnetic test detection method is the electricity and magnetic property that utilize sleeve pipe to present under electromagnetic action, carrys out the quality condition of detection thimble according to electromagnetic induction principle.Electromagnetic test detection method can determine the mass defect such as thickness, crack, distortion, bad break, inside and outside wall burn into perforation of sleeve pipe.
With EMUS detection process before steel pipe dispatches from the factory, EMUS detection process equipment uses the weldless steel tube flaw detection to especially A Saier mill milling of eddy current, ultrasonic principle to have huge advantage, energy detection thimble crack and oblique defect, the defect of reaction sleeve pipe surfaces externally and internally.Wear rib on existing detecting devices is the steel material after thermal treatment, hardness is large, wear-resistant, and anticorrosive pipe is as little in skin hardnesses such as 80S, 95S, C110, so the large wear rib of the hardness steel pipe little to hardness easily forms serious surface tear, cause the defect of quality.During flaw detection, steel pipe and wear rib sliding friction, not only can produce fretting effect tube quality to steel tube surface, and wear rib and steel pipe surface of contact also can be worn, the thickness of existing wear rib is 10mm, the serviceable life of wear rib is short, the cost of wear rib is high, increase the production cost of steel pipe's production enterprise, because wear rib is irony material, the thickness of simple increase wear rib increases the accuracy that can affect electromagnetic supersonic flaw detecting serviceable life of wear rib, and can improve the requirement of the utility appliance such as cylinder, bearing after irony wear rib weight penalty.
Utility model content:
Steel tube surface abrasive wear rib when the purpose of this utility model is to provide a kind of anti-electromagnetic test, scuffing can not be caused to the surface of steel pipe, ensure that the surface quality of steel pipe, not only steel pipe long service life, too increase the serviceable life of wear rib, for enterprise has saved great amount of cost.
The technical scheme that the utility model is taked is as follows:
Steel tube surface abrasive wear rib during a kind of anti-electromagnetic test, comprise wear rib body, fixed installation hole is provided with at the two ends, left and right of wear rib body, it is characterized in that: also comprise ball and fixing press strip, wear rib body is provided with steel pipe surface of contact, steel pipe surface of contact has at least two ball mounting grooves, ball is arranged in ball mounting groove, the upper surface of ball mounting groove given prominence to by ball, fixing press strip is arranged on the steel pipe surface of contact of wear rib body, the inner face of fixing press strip contacts with steel pipe surface of contact, on fixing press strip, the position of corresponding ball mounting groove has conical through-hole, the thickness of fixing press strip is less than the height that ball mounting groove part given prominence to by ball, the evagination peak of ball is higher than the outer face of fixing press strip, the top minimum diameter of conical through-hole is less than the diameter of ball, after installing, ball is fixed in ball mounting groove by fixing press strip, ball can rotate arbitrarily in ball mounting groove.
Further, described steel pipe surface of contact is arcwall face or V-arrangement face.
Further, described ball mounting groove is deep-slotted chip breaker or V-shaped groove.
Further, steel pipe surface of contact has 2 ~ 6 ball mounting grooves.
Further, steel pipe surface of contact has 3 ball mounting grooves.
Further, steel pipe surface of contact is provided with in the upper and lower surface of wear rib body.
It is further, fixing that press strip is dismountable is arranged on wear rib body.
Further, fixing press strip is screwed and is arranged on wear rib body.
Further, described ball is that oily nylon material is made.
Steel tube surface abrasive wear rib when using anti-electromagnetic test described in the utility model, steel pipe surface of contact increases ball and fixing press strip, ball is arranged on the steel pipe surface of contact of wear rib body, by fixing press strip, ball is spacing, prevent ball from dropping, steel pipe is changed into and ball contact by original directly contact with irony wear rib, namely also there is rolling friction to change into by original and the existing sliding friction of irony wear rib and only produce rolling friction between ball, decrease a large amount of friction force, and the surface of contact of ball and steel pipe is minimum, serious scratch can not be produced to steel tube surface, the material of ball is changed into the oily nylon material that hardness is moderate, stopped the scratch that steel tube surface causes, ensure that the surface quality of steel pipe.All be processed with steel pipe surface of contact in the upper and lower surface of wear rib body, two sides all can use, thus adds the serviceable life of wear rib.It is fixing that press strip is dismountable is arranged on wear rib body, like this after ball damages without the need to integral replacing wear rib, only need change ball, not only increase the serviceable life of wear rib, and save production cost for steel pipe's production enterprise.
