The stencil contains 74 action-packed shapes. Yoda includes a sample drawing that you can download and play with, to get a feel for how the shapes should be used: I’ve long loved these shapes (having studied mechanical engineering myself), and have put off far showcasing them on Visio Guy for far, far too long!

Orifice meter taps orientation (it depends upon the pipe direction and fluid typeīOM section is a very important section, as it affects the cost of the project.– Any plant that produces a product in liquid form!įor years one of Japan’s top Visio experts, Junichi Yoda, has offered his 3D Isometric Piping shapes to download for free.

Minimum gap requirement between the welds.

Field weld and Workshop weld Identification.

Structural penetration (if the line is crossing any structure).

Control Valve location and arrangement.

Continuation isometric drawing number (if the complete line do not fit in the single sheet).

Dimensions of all components and spools.

Slope (if it’s required as per project).

Line elevations (it can be centerline or BOP (Bottom of Pipe) elevation).Angle allocation and direction ( clockwise or anti-clockwise).

Points to be checked at drawing area are as follows. Design Pressure and Design Temperature (It’s not mandatory).Insulation and Heat Tracing Type (If the line is insulated only).Project Name, Project Code and Area Code.Here, you will learn to check the piping isometric drawing section-wise for ease of learning. The isometric drawing sheet consists of four major parts viz title block, drawing area, BOQ (Bill of Quantity ) section, and Special requirement notes section. To check the connection/end requirements for mounting the instruments. To check special items type and their dimensions To check elevation and orientation of connected nozzle To check line route, dimension, elevation, valve orientation and co-ordinates To check Design Pressure & Temperature, stress critical lines, Hydro test pressure, inspection class and type, etc. To cross-check line number, line size, insulation, special requirement notes (like no pocket, press head), etc. P&ID (Piping and Instrumentation Diagram) Documents Required for Checking Piping Isometric Drawing Documents
