Description
Technical Field

Background
The tower type container is a slender vertical structure product with the length-diameter ratio of more than 5 and the height of more than 10 meters. Due to the structural characteristics of the vertical container, design specifications impose requirements on the straightness thereof for safety. Such as:
(1) GB/T150.4-2011 pressure vessel 6.5.4 stipulates: except for the design, the barrel straightness tolerance should not be greater than 1% of the barrel length (L). When the length of the shell of the upright container exceeds 30m, the barrel straightness tolerance of the upright container is not more than (0.5L/1000) + 15.
(2) GB/T151-2014 Heat exchanger 8.2.3 stipulates: the allowable deviation of the cylinder straightness is not more than 1 per thousand of the cylinder length L, and when L is less than or equal to 6000mm, the allowable deviation is not more than 4.5 mm; l is more than 6000mm and not more than 8 mm. The straightness should be checked by measuring through the horizontal and vertical planes of the centre line, i.e. four locations along the circumference, 0 °, 90 °, 180 °, 270 °.
(3) NB/T47041- -2014 Tower Container 8.2 Specification: the straightness deviation of the body with any length of 3m is less than or equal to 3 mm; when the total length L of the cylinder body is less than 30000, the total deviation is less than L/1000; and when L is greater than 30000, the total deviation is less than 0.5L/1000+ 15.
Straightness is a form tolerance that limits the amount of variation of an actual line to an ideal line. The linearity error is the variation of the actual straight line to the ideal straight line and reflects the non-straightness of the measured straight line. The shape (ideal containing shape), size (tolerance value), direction and position. The shape deviation of the space straight line in any direction is limited.
The amount of any straight line offset in the horizontal direction is called the horizontal straightness and the vertical direction is called the vertical straightness.
At present, tower type container production plants mostly use a steel wire method, take a tensioned high-quality steel wire as a measurement base line, measure a deviation value of a measured straight line relative to the base line, and further evaluate a straightness error. The method belongs to direct measurement and is suitable for measuring the straightness error in the horizontal direction.
However, the method has large defects, such as large connecting pipes on the tower body, heavy weight of steel wires and the like, and the accuracy of the linearity value is influenced by the factors.
