Boilers and Pressure Vessels

[1988 Ed.

Hydraulic tests

44. (1) No hydraulic test of a new boiler or pressure vessel that is being examined for the purposes of section 24 shall be carried out until the maximum permissible working pressure of the boiler or pressure vessel, as the case may be, has been determined in accordance with this Ordinance. (Amended 67 of 1978 s. 21; 87 of 1988 s. 33)

(2) On the completion of an hydraulic test, the boiler, steam receiver or air receiver, as the case may be, shall be further examined by the appointed examiner who carried out the test in order to ascertain the condition of any parts thereof that may have been affected by the hydraulic pressure.

(3) (a) An hydraulic test of a boiler or steam receiver, other than a new boiler or a new steam receiver that is being examined for the purposes of section 24, shall be to one and one-half times the pressure that will be specified in the certificate of fitness as the maximum permissible working pressure of the boiler or steam receiver.

(b) An hydraulic test of a new boiler or steam receiver that is being examined for the purposes of section 24 shall be to one and one-half times the pressure that will be specified in the certificate of fitness as the maximum permissible working pressure of the boiler or steam receiver. (Amended 67 of 1978 s. 21)

(4) An hydraulic test of an air receiver shall, in relation to the pressure that will be specified in the certificate of fitness as the maximum permissible working pressure of the air receiver, be in accordance with a recognized engineering standard or code or as follows-

(a) in the case of a seamless steel air bottle-

(i) shall be to twice that pressure where the maximum permissible working pressure does not exceed 14 megapascals;

(ii) shall be to that pressure plus 14 megapascals where the maximum permissible pressure exceeds 14 megapascals but does not exceed 28 megapascals; and (Replaced 87 of 1988 s. 19)

(iii) shall be to one and one-half times that pressure where the maximum permissible working pressure exceeds 28 megapascals; and

(b) in the case of other air receivers-

(i) shall be to twice that pressure where the maximum permissible working pressure does not exceed 700 kilopascals; and

(ii) shall be to one and one-half times that pressure plus 350 kilopascals where the maximum permissible working pressure exceeds 700 kilopascals. (Replaced 87 of 1988 s. 19)

(Replaced 67 of 1978 s. 21. Amended 87 of 1988 s. 19)

(5) An hydraulic test for the purposes of section 30 or 41 of a pipe that conveys or will or may convey oils, steam or water under pressure shall--- (Amended 87 of 1988 s. 37)

(a) in the case of copper pipes, be to twice the pressure that is or will be specified in the certificate of fitness as the maximum permissible working pressure of the boiler or steam receiver, as the case may be, and, in the case of steel pipes, be to 3 times that pressure; or
