What is allowable nozzle load?

Nozzle Loading. Nozzle loads are the net forces and moments exerted on equipment nozzles. Pump nozzles may not always be subject to the maximum allowable resultant force and resultant moment simultaneously. Thus an increase in either the resultant applied force or the resultant applied moment may be permitted.

What is equipment nozzle?

A nozzle is either a Creo Parametric part or assembly that has a coordinate system representing a connection port. It is also used for end compatibility checking between a nozzle and its connected pipeline.

How do you reduce nozzle loads?

To minimise nozzle loading, all piping should be externally supported on both the inlet and discharge sides of the pump. Pipelines must be supported by external means at regular intervals to prevent them from sagging due to their intrinsic self weight and the weight of the fluids inside the pipe.

What is nozzle in pressure vessel?

A pressure vessel nozzle is an opening in the pressure vessel through which fluid enters or exits the pressure vessel. The Nozzle, in general, projects from the pressure vessel’s surface and ends with a means of joining (flanged or welded) piping or equipment.

What is pump nozzle?

The pump-line-nozzle injection system is so-called for producing high fuel pressure in a pumping element, transferring the fuel pressure pulse through a high pressure injection line, and then spraying this fuel into the cylinder via the nozzle of an injector [113] .

What WRC 107?

What is the WRC-107 Analysis? The WRC-107 Analysis calculates the combined local stress intensity from external loads at the junction of an attachment and a shell or head. The method may be employed for structural supports or nozzles.

What is nozzle orientation?

4.8 Nozzle Orientation shall be developed with zero (0) degree aligned to the plant North and incremental degrees shall be indicated clockwise. 4.12 Davit and manhole opening shall be indicated in the Nozzle Orientation drawing. Manhole opening shall be oriented such that they are pushed closed in the escape direction.

What is nozzle reinforcement?

Openings in the shell which are reinforced with excess thickness available in the shell, nozzle neck, or weld are defined as “integrally reinforced.” Section VIII acknowledges the variation in stress for these integrally reinforced nozzles with respect to the orientation of a section cut through the opening.

What is the cost of nozzle?

Questions & Answers on Spray Nozzles

What is suction nozzle?

The pump suction nozzle is the cross-section (circular cross-section) to be defined at the pump casing’s inlet side as a boundary between the suction-side section of the pump system and the pump itself (inlet cross-section).

What is the difference between WRC 107 and 297?

WRC 297 differs from the widely-used WRC 107 primarily in that WRC 297 is designed for larger d/D ratios (up to 0.5). WRC 297 also computes stresses in the nozzle and the vessel, whereas WRC 107 only computes stresses in the vessel.

What are allowable loads acting on nozzles of mechanical equipment?

This post specifies the criteria to be adopted while defining the allowable loads acting on the Nozzles of the various Mechanical equipments, due to the loads imposed by the connected piping system. These loads shall be included in the Mechanical design of the equipments during procurement.

How big can a nozzle load be for a pump?

Allowable load values up to nozzle size 16 inch is provided in the table. For higher sizes, the ANSI standard is used. If the pumps are not designed as per API standard (nowadays non API pumps are most frequently used due to its lower costs) obtain loads from the vendor.

Can a nozzle be exceeded by a piping system?

However, depending on the configuration of the connected Piping system or due to the various design conditions analyzed, the loads imposed on the Nozzle may exceed these allowable values. In such cases, theactual loads shall be communicated to the Supplier.

How does a piping stress engineer check the nozzle loads?

As a minimum, the Piping Stress Engineer shall ensure that the loads on the Nozzle of the Mechanical Equipments are within these values. In the event the loads are exceeding the allowable loads values, prior approval from the supplier shall be taken.
