After above-mentioned raw materials is processed into rod base carries out hot piercing hot rolling or hot piercing cold rolling or hot piercing by conventional method
Processing or hot extrusion cold rolling or extruding hot rolling or heat extruder processing, or cold rolling after hot piercing hot rolling,
Or the rolling of hot piercing hot push pipe, or the rolling of hot extrusion hot push pipe, and control Fe≤0.3% in titanium alloy T A18, C
≤ 0.08%, N≤0.05%, H≤0.015%, O≤0.2%；Its TA18 seamless pipe specification: pipe external diameterWall thickness 0.9～400mm (but external diameter have to be larger than 2 with the ratio of wall thickness) × length
100～24000mm, square tube 10～1500mm × 10～1500mm × wall thickness 0.9～400mm (but each length of side must
Adjacent 2 wall thickness sums must be more than) × length 100～24000mm, special pipe large head external diameterWall thickness 0.9～400mm (but external diameter have to be larger than 2 with the ratio of wall thickness) × small head external diameterWall thickness 0.9～400mm (but external diameter have to be larger than 2 with the ratio of wall thickness) × length
100～24000mm, special pipe large head external diameter have to be larger than small head external diameter；
When preparing TA18 titanium alloy tube, first flawless optical wand blank is placed on heating furnace (gas furnace
Or chamber type electric resistance furnace or induction heater) in carry out the heating that heats up；Heating-up temperature 600 DEG C～1100 DEG C, insulation
Time=(heating ingot blank diameter/2) mm+ (20～90) minute.Carry out cold rolling after hot piercing or hot extrusion again
Carry out again after system, hot piercing or hot extrusion hot rolling finished product, cold rolling finished product after hot piercing hot rolling,
Carry out being machined to product after hot piercing or hot extrusion after heat push pipe mill product, hot piercing or hot extrusion, cold rolling
When heating rolling deflection for (20%～90%)/time, the temperature after hot piercing, after hot extrusion, after hot rolling
300 DEG C～900 DEG C.
Finished product after rolling completes uses oxidizing annealing or vacuum annealing, and the annealing temperature of oxidizing annealing is
400～1000 DEG C are incubated 0.5～8 hour；The annealing temperature of vacuum annealing is that 400～1000 DEG C of insulations 0.5～8 are little
When, the finished product after heat treatment then to carry out washing after pickling or alkali cleaning, pickling or alkali cleaning again, it is thus achieved that finished product,
Or once machine acquisition finished product again.
Tensile strength (Rm) in this product titanium alloy T A18 hot-rolled pipe performance is after heat treatment and solid solution aging
Up to (500～1000) MPa, elongation percentage is (6～25) %, two annealing in stress relief annealing and perfect recrystallization
In the state of kind, its metallographic structure is uniform.
The present invention compared with prior art, has a following beneficial effect:
1. corrosion-resistant: titanium alloy T A18 seamless pipe intensity (Rm) (500～1000MPa) of the present invention is more resistance to than steel pipe
Corrosivity is good.
2. reduce cost, shorten the production cycle: will carry out after the rolling of existing titanium alloy pipe production process per pass
Vacuum annealing, and after the titanium alloy T A18 seamless tubular goods production technology of the present invention is hot piercing or hot extrusion pipe
Carry out mill product or machining finished product, so both reduce power consumption cost and shorten the production cycle.
3. yield rate is high, and quality is good, and performance is excellent: it is high that TA18 seamless pipe of the present invention draws hole pipe yield rate than bar,
TA18 seamless pipe utilizes hot piercing or hot extrusion pipe to carry out mill product or machining finished product, is lost little,
Yield rate is high, and hole pipe drawn by bar then needs to draw out a lot of bits waste product, and loss is big, and yield rate is low, and bar is drawn
Hole pipe is quality and the performance of bar, and the quality of hole pipe drawn by bar, performance prepares TA18 far away from by top method
The quality of seamless pipe, performance.
4. service life is long: the congenital dense structure of TA18 seamless pipe of the present invention, and sheet material welded pipe is then in weldering
At seam, structural state is inconsistent with matrix, easily causes fatigability corrosion cracking, so there being TA18 seamless pipe ratio
Sheet material welded pipe is long for service life.
