What is the purpose of pressure vessel Code?

The ASME Boiler and Pressure Vessel Code (BPVC) is the standard that regulates the design and construction of boilers and pressure vessels.

What is a pressure vessel head?

A head is one of the end caps on a cylindrically shaped pressure vessel.

What are instruments used while inspecting pressure plate?

Depending on usage, a gauge can be described as “a device for measuring a physical quantity”, for example “to determine thickness, gap in space, diameter of materials, or pressure of flow”, or “a device that displays the measurement of a monitored system by the use of a needle or pointer that moves along a calibrated …

How do I choose a vessel head?

The designer should select a head thickness that can be formed as economically as possible.

Hemispherical, torispherical and elliptical heads are commonly used for process equipment.
Hemispherical head is used only for special purposes because of its very high fabrication cost.

What are the types of pressure vessels?

There are specialized application pressure vessels such as reactors and regeneration vessels, however most correspond to the three common types.

Storage Vessels. The most prolific of all pressure vessels are the various storage vessels required for industrial processes.
Heat Exchangers.
Process Vessels.

How do you perform a pressure vessel inspection?

These are the list of documents which are normally agreed to be presented to the inspector:

Pressure Vessel Manufacture Quality Control Plan.
Pressure Vessel Inspection and Test Plan.
Pressure Vessel Data Sheet.
Pressure Vessel Approved Drawings.
Pressure Vessel Strength Calculation Sheets.

What are the components of pressure vessel?

There are three components in a pressure vessel that are considered to be basic – the shell casing, necessary attachments and a base. The other components are considered to mainly include the nozzle and the head. The Shell contains the pressure and consists of plates that have been welded together with an axis.

Why do you need a nameplate for a pressure vessel?

1. Our nameplates need to display more information than found on imported vessels from e.g. USA, Europe etc. A second nameplate usually has to be attached showing this information. 2. The whole point is to design, fabricate, select materials, weld, inspect, test and compile documentation etc. that meets the full requirements of the code selected.

Where do you put the design code on a vessel nameplate?

On the nameplate we put a line called DESIGN CODE: ASME VIII DIV 2 : XXXX where XXXX is the year of the latest release for that code. This is to show that the vessel has been designed to the code mentioned – i.e. all the calcs, all the drawings show correct fittings, welds etc.

How does a pressure vessel test plate work?

First is the test method, and seconder is in the test temperature. So pressure vessel manufacturer requests that the plate material supplier provide a test plate and send the test piece to a laboratory for impact testing based the SA 516 Gr.60 specification.

Can you use ASME on a vessel nameplate?

An inspector recently said that it is prohibited to use “ASME” at all on a nameplate – only U stamp holders can do so. We have to remove the line for the design code on the nameplate. We are not mentioning “fabricated” – only designed. Thank you for your time in reading this.
