Description
Technical field
The utility model relates to a kind of steel tube end part maximum linear degree and measures frock and steel tube end part linearity measurer, belongs to pipe straight line degree measuring tool technical field.
Background technology
At present, linearity is most basic part in geometric tolerances.Linearity is that the actual straight line of restriction is to a kind of form tolerance of ideal line variation.Linearity is made up of shape (desirable contained shape), size (tolerance value), direction, position four elements.For limiting the rectilinear form deviation in a plane, restricted quarter straight line form variations in one direction, the form variations of restricted quarter straight line in either direction.
API SPEC 5CT sleeve pipe and oil pipe specification require as follows to the tube end straight line degree measurement of specification >=114.3mm:
Use the ruler measuring junction pipe end straightness that at least 1.80m is long, ruler at least should have 0.30m to contact with the tube surface beyond curved end scope.
Only guaranteed ruler has at least 0.30m to contact with the tube surface beyond pipe end bending range, guarantee pipe end straightness measuring accuracy.Therefore the measuring method that current domestic steel pipe manufacturing works pass through is the steel ruler (heavily about 6KG) lengthened with one, first and second liang of bit trial personnel are needed to coordinate, wherein ruler is firmly pressed in steel tube surface by first, guarantee that ruler has at least 0.3m to contact with the tube surface beyond pipe end bending range, allow second measure bending action at the other end metallic tape of ruler simultaneously.This measuring method is larger by artificial influence factor: 1. whether first is by the flat surface of ruler compacting at steel pipe; 2. whether first have found the measuring surface of steel pipe maximum deflection; 3. because blade weighs about 6KG, long-time to measure workman easily tired; If 4. second straight steel ruler when reading is unstable, be difficult to read correct numerical value.
In order to ensure tube end linearity, factory's reply tube end linearity is measured, but because existing survey instrument cannot ensure the precision of tube end straight line degree measurement, this just causes factory cannot find out the underproof pipe of end linearity in time, the underproof pipe of these pipe end straightness is caused to forward lower operation to, or as product export.
The oil of the underproof tube to tubesheet of pipe end straightness, casing thread connection and body are eccentric, and this will reduce oil, casing joint strength of joint and sealing property.Factory, once find that the oil of the underproof tube to tubesheet of pipe end straightness, casing thread connection are defective, should process after crop again.If oil, casing length meet standard-required after crop, factory can lose pipeline section and the crop expense of crop part in vain; If oil, casing length do not meet standard-required after crop, whole oil, sleeve pipe are scrapped, and factory's loss is larger.In addition, when in machining screw bond process, the underproof pipe of pipe end straightness rotates, vibrations are very serious, and this can cause threading machine bearing and other part earlier period damage, shorten the thread processing machine tool life-span, finally make plant produced cost increase considerably.
After the underproof tube to tubesheet of tube end linearity becomes line pipe, easily produce misalignment when the seam of pipeline field joint, and increase welding vestige stress, final reduction weld quality.
Ensure oil pipe, sleeve pipe and line pipe end straight line degree measurement precision, key is the design of tube end straight line degree measuring tool.
