Piping Basics3

Pump:A pump is a device used to move fluids, such as liquids, gases or slurries. It increases the mechanical energy of the fluid. The additional energy can be used to increase Velocity (flow rate), Pressure and Elevation.


Isometric Drawing:A piping isometric drawing is a 2D drawing in which piping is represented like a 3D drawing. In CAD drawing, only x and y co-ordinates are used to draw entire drawing.


Pipe Support:A pipe support or pipe hanger is a designed element that transfers the load from a pipe to the supporting structures. The load includes the weight of the pipe proper, the content that the pipe carries, all the pipe fittings attached to pipe, and the pipe covering such as insulation.



Uses of 3D Modeling:

Able to visualize more ‘what-if’ scenarios during the design process.

It is easier to create model renderings and animations for design proposals or reviews.

More effective internal 3D model reviews.

Faster design output and productivity (roughly 50% faster on average over 2D).

Generation of virtual prototypes allows non-CAD people to participate in the process.

Easily incorporates latest design changes and engineering  scope.

Test and validate your designs to reduce costs from quality problems, errors, ECO’s.




Weld Joint Types:       

1.In Butt welded type, the parts lie in the same plane and are joined at their edges.

2.The parts in a corner joint form a right angle and are joined at the center of the angle.

3.Lap joint consists of two overlapping parts.

4.In a Tee-joint, one joint is the right angle to the other joint in the approximate shape of the letter “T”

5.The parts in edge joint are parallel with at least one of their edges in common and the joint is made at the common edge(s).

Similar to other pipe manufacturing processes, the manufacture of Double Submerged Arc Welded Pipe involves first forming steel plates into cylindrical shapes. The edges of the rolled plate are formed so that V-shaped grooves are formed on the interior and exterior surfaces at the location of the seam. The pipe seam is then welded by a single pass of an arc welder on the interior and exterior surfaces (hence double submerged). The welding arc is submerged under flux.

Function’s of Pipe Support:

To carry load, To ensure that material is not stressed beyond a safe limit,   Holdup of liquid can occurred due to pipe sagging (allowdraining),   To permit thermal expansion ,To withstand and dampen vibrational forces applied to the piping
