Precision bright tube

Author: Liaocheng precision steel pipe factory source: unknown date: January 30, 2019 21:35
        precise Bright tube It refers to a kind of high-precision pipe processed by cold drawing, hot rolling and other processes. It has the characteristics of high pressure, high precision, no deformation, flattening and crack free. The most obvious difference with ordinary bright tube is that the size precision of precision bright tube is very high, which can be accurate to 0.1 mm; And the inner and outer diameter finish is higher. Because of these advantages, precision bright tube is widely used in automobile, motorcycle, electric vehicle, household appliances, petrochemical, electric power, ships, aerospace, bearings, pneumatic components and other industries, and can also be used in steel sleeve, bearing, hydraulic, mechanical processing and other industries.
       Precision bright tube Product features and advantages

1. Precision bright tube is made by cold rolling process, so it has advantages in precision, finish and size.
        2. The biggest characteristic of precision bright tube is no welding seam, with good toughness, so the ability to bear pressure is strong.

3. The hollow section of precision bright pipe, with larger internal area, lighter weight and strong seismic resistance, can play an important role in the field of pipeline transportation.

4. Economic and environmental protection, non-toxic pollution, long service life, in line with the requirements of modern sustainable scientific development concept.

      Geometric dimension and shape inspection method of precision bright tube:

1. Precision tube wall thickness inspection of bright tube: 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. Precision tube length inspection of bright tube: 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 tube end face of bright tube: angle ruler and clamp plate.
