2. SUMMARY DESCRIPTION OF SPECIFICATION

2.1 Scope The criteria specified shall apply to process nozzles NPS 2" and larger for vessels, shell and tube heat

exchangers included if any, and for skid edges. The criteria do not apply to instrument connections,

inspection openings and man ways.

Nozzles shall be designed to withstand forces and moments from thermal expansion and dead weight

of piping. Piping reactions shall be within the limiting criteria set by this specification. In the case of

bursting disc nozzles, the discharge shock load shall be added to the axial force Fa.

Nozzles shall be suitable for a total number of 7,000 full temperature cycles for the expected life times.

Loads which exceed the figures given in this specification will be advised separately.

The forces and moments contained in this specification are considered as minimum criteria in order to

allow for an economical design of the connecting piping.

If the specified loads require the shell thickness to be increased, then the SUPPLIER shall state the

increased thickness in the quotation.

Flanges shall conform to ASME B16.5 (NPS 1/2, Through NPS 24) or ASME B16.47 (NPS 26 through

NPS 60) Series A. Welding neck flanges shall be used for vessels.

All Pressure Vessels shall be designed, fabricated, inspected and tested in accordance with Technical

Specification for Pressure Vessels, data sheets and standards listed in the above specification.

3. EXTERNAL FORCES AND MOMENTS ON NOZZLES

3.1 Nozzles to Shells Each nozzle shall be capable of withstanding forces and moments from external piping under design

conditions and considered to be acting at the intersection of nozzle and shell in the corroded condition.

The forces and moments acting on the nozzles have been specified as per flange rating as per section

4. Nozzle Minimum Loading Requirements of this specification.

The orientation of the directions of forces and moments acting on the shell has been defined as per

section 5. "Nomenclature" of this specification. The forces and moments can be expected to apply plus

or minus and should be combined simultaneously at all major nozzles.

In certain circumstances it may be necessary to consider additional loads. These cases will be informed

to PURCHASER/COMPANY for approval. In mentioned conditions, engineering sub contractor will state

the actual loads and the manufacturer shall carryout calculations to confirm the structural integrity and

stability of the equipment.

3.2 Nozzles to Formed Heads The calculation shall be based on:

For Nomenclatures refer section 5.0

Calculation method and design criteria for the basic stress intensity limits shall be based as follows:

- Calculation method:

WRC 107/297 (cylindrical shells)

WRC 107 (heads)

- Design criteria:

PD 5500 Appendix A

Documents and codes shall be the latest edition.

The effect of design pressure loading together with an appropriate Stress Concentration Factor

(SCF) shall be taken into account according to PO 5500.

The stresses shall be checked in two locations:

B4




- Shell/head to nozzle junction

- At the outer edge of the reinforcing ring or insert plate (insert plate: a local increase of

shell/head thickness around the nozzle).

3.3 Additional Reinforcement Whenever stresses based on loadings calculated according to the above requirements exceed the

allowable stresses, the Manufacturer shall apply additional reinforcing above the reinforcing required for

pressure loading as follows:

- A reinforcing ring when not before required for pressure loading

- A larger reinforcing ring than already required for pressure loading

- A thicker/larger insert plate than already required for pressure loading

In case the calculated stresses are still too high, the Manufacturer shall inform the

PURCHASER/COMPANY on the multiplication factor (
