Industrial Process Of Piping: Industrial process of piping involves the usage of piping to transport fluids between storage tanks and processing equipment. Types Of Piping: Plumbing  Civil Piping Transportation Piping Uses Of Industrial Piping: Water  Natural Gas  Electric Power Specially items like paper pulp or liquid foods  Sewer Storm drains, etc. Pipe Drafting: Pipe can be drawn into two forms Double-line & Single-line . Pipe drafting utilizes many different types of drawings: Flow Diagrams  Structural and Site plans Mechanical and Instrumentation Drawings Iso-Symbols Of Fittings: It is a mechanical tool which is used to join two or more components together. Iso-Symbols Of Flanges: A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. Iso-Symbols Of Valves: A valve is a device that regulates the flow of fluids, fluidised solids, slurries...

Intersection Of Solids: Solids are obtained by the combination of of two or more basic solids. When two or more solids combine, a definite curve/line is seen at their intersection. This curve/line is called curve/line of intersection (COI / LOI) and it is the result of inter-penetration of solids. Applications Of Intersection Of Solids: Designing a sheet metal objects. Automobile Parts. Moulding patterns. Forged end of connecting road. Intersection of two contacting surface, etc. Inter-Penetration Of Solids: When one solids penetrates another solids then their surfaces intersect and at the junction of intersection a typical curve is formed, which remains common to both solids. This curve is called Curve of Intersection and it is a result of inter-penetration of solids. Cases Of Intersection Of Solids: First we need to discuss the general solution steps of how we draw intersection of solids diagram. So know, we are going to discuss the basic steps:...

Isometric Drawing: A type of pictorial projection in which all three dimensions of an object are shown in one view. In this 3-D drawing of an object, all three dimensional axes are maintained at equal inclinations with each other , i.e. 120 degrees. All mutual perpendicular plane surfaces of an object and the edges formed by these surfaces are equally inclined to POP. When orthographic views are given, a good imagination is needed to visualize the object in 3-D space.   Some Important Terms: The angle between these axes are equal i.e. 120 degrees, so called Isometric Axes . The line parallel to these axes are called Isometric Lines . The planes representing the cube are called Isometric Planes . The reduction is approximately 0.815. It forms a reducing scale which is used to draw isometric projection and is called Isometric Scale . True-length Distances are shown along isometric lines.  Isometric line is the line that run parallel to any of the isomet...

Assembly Drawings: It is drawing of machine with all of its components located and identified. Ballooning: In Assembly Drawing, a part is located and identified by using a circle containing the part number and a leader line that points to the corresponding part. Development Of Solids & Sectioned Solids  Development Of Solids: A graphical method of obtaining an area of the surfaces of a solid is termed as Development Of Solids  OR It is the unfold/ unrolled /plane figure of a 3-D object. For Example:      1. When a solid is opened out and its complete surface is laid on a plane, the surface of the solid is said to be developed.      2. A piece of paper having the shape of sector is rolled so that its extreme edges meet, we get a cone.      3. A rectangle sheet when rolled so that extreme edges meet, we get a cylinder. Types Of Development Of Solids: There are two types of Develo...

Projection: The term Projection is defined as: Presentation of an image or an object on a surface. The principles used to graphically represent 3-D objects and structures on 2-D media and it based on two variables: Line of Sight.  Plane of Projection.  Line of Sight & Plane of Projection: Line of sight is divided into 2 types: Parallel Projection Converging Projection  & A plane of projection is an imaginary flat plane upon which the image created by the lines of sight is projected. Orthographic Projection: When the projectors are parallel to each other and perpendicular to the plane of projection. The lines pf sight of the observer create a view on the screen. The screen is referred to as the Plane of Projection (POP). The lines of sight are called Projection lines or projectors. Rules of Orthographic Projection: Edges that are parallel to a plane of projection appear as lines. Edges that are incl...

Conics: It is defined as; Conics are the curves formed by the intersection of a plane with a right circular cone.   Ellipse: It is created when a plane passes through a right circular cone at an angle to the axis that is greater than the angle between the axis and the sides. Parabola: It is created when a plane intersects a right circular cone parallel to the side of the cone. Hyperbola: It is created when a plane passes through a right circular cone at an angle to the axis that is smaller than do the elements. Cycloid: It is a locus of a point on the periphery of a circle which rolls on a straight line path. Involute: It is a locus of a free end of a string when it is wound round on a circular pole. Epi-Cycloid: The path traced out by a point on the edge of a circle of radius rolling on the outside of a circle of radius. Hypo-Cycloid: The curve produced by fixed point on the circumference of a small circle of radius rollin...
