 Product display of precision seamless steel pipe
    Precision seamless steel pipe Compared with other steel pipes, it is more stable, and because of its high density, it also greatly saves the consumables during processing and reduces the waste of materials. Moreover, different models and specifications of precision seamless steel pipe also make it more widely applicable. Therefore, compared with other steels, precision seamless steel pipe is a more economical material and a better choice for users.
     
The commonly used materials of precision seamless steel pipe are: 10 mm, 20 mm, 35 mm, 45 mm, 16Mn (Q345A, B, C, D, e) 27SiMn, 20Cr, 40Cr 、GCr15 And other materials.

    Inspection method for geometric dimension and shape of precision seamless steel pipe:

1. Precision wall thickness inspection of seamless steel pipe: micrometer and ultrasonic thickness gauge, with no less than 8 points at both ends and recording;

2. Inspection of outer diameter and ovality: calipers, vernier calipers and ring gauges are used to measure larger and smallest points;

3. Seamless steel pipe precision pipe length inspection: steel tape, manual and automatic length measurement;

4. Bending degree inspection: measure the bending degree per meter and the whole length with a ruler, level ruler (1m), feeler gauge and thin line;

5. Inspection for groove angle and blunt edge of precision pipe end face of seamless steel pipe: angle ruler and clamp plate.

After the geometric dimension and shape of the precision seamless steel pipe are checked, the chemical composition and mechanical properties shall be tested in addition to hydrostatic test, flanging, flaring and flattening. Hot rolling shall be delivered in hot rolling state and cold rolling (drawing) shall be delivered in heat treatment state.
