Abstract
The invention belongs to a petroleum detecting special pipe in the technical field of petroleum detecting equipment. The special pipe is made of titanium alloy which is made by adding metallic aluminum and metallic vanadium into metallic titanium. The titanium alloy pipe is made of the titanium alloy by the following steps: (1) rolling: firstly, original blank is extruded by an extruder or is cross-pierced and processed into the pipe blank, then the burrs and cracks on the surface are grinded off by a grinding wheel machine, the cracks of the inner hole are removed by a deep hole lathe, and then the pipe blank is formed by more than twice rolling; (2) annealing and figuring are carried out when the deformation amount in the step (1) is larger than 10 percent, the annealing temperature is 560 to 640 DEG, insulating for 2 to 4 hours, and then the pipe is taken out of the furnace at room temperature. The invention has the advantages of no magnetism, corrosion resistance, high pressure resistance and high strength of the titanium alloy pipe, thus prolonging the service life. The design requirements can be achieved better between by the titanium alloy pipe processed in the invention.
Description
Technical field
The invention belongs to oil exploration equipment technical field, particularly a kind of tubing of petroleum detection special use.
Background technique
Existing petroleum detection generally adopts stainless-steel pipe, and its material is Austenitic Stainless Steel, corrosion-resistant, and high temperature resistant degree is lower, therefore causes the life-span very short, needs frequently to change.
Substitute products are nickel-base alloy, because the raw-material price fluctuation of market nickel, cost is seriously out of control.Because the ratio of nickel is great, is unsuitable for deep-well and uses in addition,, lose more serious because the equipment that the weight of nickel-bass alloy material causes is lost.
Also having main a bit is exactly to survey with tubing non-magnetic requirement, and the content of iron is the key factor that influences validity in the tubing, and owing to titanium iron content not itself, the iron content in the titanium material can be controlled.The light specific gravity of titanium only is equivalent to 1/2nd of nickel, and is stainless 3/5ths, and titanium alloy and other metals have incomparable advantage on weight.
Summary of the invention
The object of the invention provides a kind of special titanium alloy tube for petroleum detection and preparation process thereof, improving every technical performance of petroleum detection tubing, such as corrosion resistance, intensity and withstand voltage etc.
Specifically, special titanium alloy tube for petroleum detection, it is to make tubing with the titanium alloy that interpolation metallic aluminium and vanadium metal in the metal titanium are made.
Metal Ferrum content is lower than 0.08% in the described titanium alloy, and the content of aluminium is 3-6%, and the content of vanadium metal is 2.5-4%, and all the other are metal titanium and inevitable impurity.
Titanium alloy of the present invention is made titanium alloy pipe according to following steps:
(1) rolling: as at first original blank to be processed into pipe by extrusion press extruding or roll piercing, to fall the burr crackle on surface then by the grinder reconditioning, by the deep hole lathe crackle of endoporus is removed, by the rolling-forming more than 2 times;
(2) amount of deformation was annealed greater than 10% o'clock in step (1), reconditioning, and annealing temperature 560-640 degree is incubated 2-4 hour, and room temperature is come out of the stove.
Advantage of the present invention is that titanium alloy pipe is in light weight, and is nonmagnetic, corrosion-resistant, high pressure resistant and intensity is high, prolonged working life, can better finish designing requirement by the titanium alloy tube of this patent processing.
