N.J. Admin. Code § 12:90-5.9

Current through Register Vol. 57, No. 1, January 6, 2025

Section 12:90-5.9 - Class III unfired pressure vessels-New Jersey Approved

(a) This section shall apply to a procedure to obtain approval for a non-code vessel as a Class III unfired pressure vessel known as New Jersey Approved.

(b) The application for a New Jersey Approved unfired pressure vessel shall meet the following requirements:

1. To expedite handling of a request for non-code construction review, all materials shall be gathered and submitted, in as complete a form as possible, by the user;

2. When it is necessary to defer filing of some material, such omission shall be prominently noted in the letter of application;

3. All written material shall be in the English language; provided, however, that written material that is in a language other than English may be submitted along with an English translation that is certified to be correct;

4. All letters of application shall be accompanied by payment of $ 6,000 for each non-code design. Additional fees shall be required for designs submitted for a single project and shall be repetitive for each user-application of the design;

5. Following final inspection and test, the manufacturer shall complete an appropriate manufacturers' data report form. This form shall be certified by the New Jersey authorized inspector who will identify his New Jersey Certificate of Competency license number; and

6. Reference to conformance to the ASME Code shall be deleted where such appears on the form. The completed form, in duplicate, together with a facsimile of the stamping, shall be filed for registry with the Bureau of Boiler and Pressure Vessel Compliance.

(c) The New Jersey Approved unfired pressure vessel may require periodic reinspection.

(d) Compliance with (e) through (m) below shall be required to establish ASME Code equivalency.

(e) The maximum allowable working pressure of the New Jersey Approved unfired pressure vessel at a given temperature may be limited to a maximum of 80 percent of that to which the vessel can be subjected in accordance with the ASME Code.

(f) Drawings, fully descriptive of the unfired pressure vessel, with special attention to clarity of weld details and nozzles and other openings, shall be submitted.

(g) Identification of materials within ranges of chemical and physical characteristics shall match with those listed in the appropriate ASME Code section.

(h) Full computations shall be provided, using appropriate formulae as required, by the applicable code section. All computations shall be labeled and ASME Code reference given. Where ASME Code formulae do not apply, the rationale of alternate methods of computation shall be clearly demonstrated. Finite Element Analysis is an acceptable alternative method to demonstrate design rationale.

(i) Evidence of appropriate welding procedures and operator's tests shall be supplied. If such is unavailable from the manufacturer, verification of sound welding shall be made as required by the Bureau of Boiler and Pressure Vessel Compliance.

(j) All material shall be reviewed by a New Jersey registered professional engineer, who shall verify its equivalency to the basic requirements of the ASME Code.

(k) The user's letter of application shall briefly outline the nature of the substance to be contained by the unfired pressure vessel, proposed pressure and temperature conditions and heating, cooling or pressurizing medium.

(l) All of the foregoing documentation shall be forwarded to the Bureau of Boiler and Pressure Vessel Compliance by the user of the vessel with a letter requesting that New Jersey Approved classification be assigned, if warranted.

(m) When approved, the unfired pressure vessel shall be stamped New Jersey Approved.
