phenomenon of wrinkling (flange instability) is specific to the process of deep-drawing. Instability in the work piece, also called wrinkling of the walls. In deep drawing process the main objectives are to obtain defect less or minimum defects in product. Prediction of wrinkling is a very important process for a deep-drawing operation.

flange discontinuity. Bending stresses can also be seen in the bolt. Although the stresses look high compared with psi membrane allowable stress for the flange and pipe, the stresses are minor if compared with a local discontinuity limit of 3x20, psi. This flange. Figure 3: The intersection of the lines plotting the BHF and the draw depth of a cup reveal the maximum possible draw depth for a given cup. Varying the BHF Often, a constant BHF is applied throughout the forming stroke, even though the drawing ratio decreases as the flange is drawn in, as shown in Figure 1.
Cup Drawing Test. The schematic of a CDT is shown in Figure 1. The cup is always drawn to the same depth of 80 millimeters. During the test, the sheet is not drawn completely, and some flange remains at the end of the operation. The perimeter of the flange is measured for each specimen. No-Hub Pipe & Fittings. ASTM Specification for Hubless cast iron soil pipe and fittings for sanitary and storm drain, waste, and vent application Scope: This specification covers hubless cast iron pipe and fittings used in sanitary drain, waste, and vent (DWV), sewer, and storm drainage applications. This system is intended for use in nonpressure applications.

connection (flange) can be calculated. In this way the load limits and load capacity of the nozzle can be determined and are available at an early stage to the piping designer (pipe stress analyst). Successively it is the responsibility of theFile Size: KB.

Deep (or cup) drawing: In this operation, forming of a flat metal sheet into a hollow or concave shape like a cup, is performed by stretching the metal in some regions.
A blank-holder is used to clamp the blank on the die, while the punch pushes into the sheet metal. The sheet is drawn into the die hole taking the shape of the Size: 1MB.

PRESSURE VESSELS, Part I: Pressure Vessel Design, Shell, Head, Nozzle and Basic Flange STUDY NOTES Instructor: Javier Tirenti [email protected] Deep drawing is a manufacturing process that is used extensively in the forming of sheet metal into cup or box like structures.
Pots and pans for cooking, containers, sinks, automobile parts, such as panels and gas tanks, are among a few of the items manufactured by sheet metal deep drawing. round. A flange added to the top of the shell will minimize this, but the smaller the flange, the less strength it has to keep the shell round.
Specifying a Drawn Shell Since the original blank is so altered by the deep draw process, the wall thickness cannot be specified in terms of mill tolerances.
Depending on application, the three. flat face flanges. All CG and CGI Gaskets for these standard flanges are in (mm) thick, fitted with in (mm) thick solid metal rings, unless otherwise stated.

Wide Flange Beam Dimensions Chart for sizes, dimensions and section properties of steel wide flange beams. Wide flange beams are designated by the letter W followed by the nominal depth in inches and the weight in pounds per foot.
Thus W12 × 19 designates a wide flange beam with a depth of 12 inches and a nominal weight of 19 pounds per foot. Fig.
1 flange coupling Fig. 2 flange coupling Fig. 3 flange coupling. This helps to bring the shafts into line and to maintain alignment. The two flanges are coupled together by means of bolts and nuts. The flange coupling is adopted to heavy loads and hence it is used on large shafting.
The flange couplings are of the following three types: 1. The Fukui conical cup test involves both stretching and drawing over a ball. The opening is much larger than the ball so a conical cup is developed. The flanges are allowed to draw in. Figure shows the setup. A failed Fukui cup is shown in Figure Figure shows comparison of the relative amounts of stretch and draw in these tests.
8 Long lasting copper tube is a favorite choice for plumbing, heating, cooling and other systems. In the United States, it is manufactured to meet the requirements of specifications. What is an Isometric Drawing. An isometric drawing is a type of pictorial drawing in which three sides of an object can be seen in one view.
ISOMETRIC DRAWINGS ISOMETRIC DRAWINGS -- Dimensions It’s popular within the process piping industry because it can be laid out and drawn with ease and portrays the object in a realistic view. Process Piping Fundamentals, Codes and Standards – Module 1 1 Process Piping Fundamentals, Codes and Standards One of the most important components of the infrastructure is the vast process.
A +/- 1 degree tolerance on all bend angles is generally acceptable in the industry. Flange length must be at least 4 times the material thickness. Rule of thumb It is recommended to use the same radii across all bends, and flange length must be at least 4 times the material thickness.
Dimensions, Tolerance and Related Attributes Dimension – ‘a numerical value expressed in appropriate units of measure and indicated on a drawing along with.
Drawing of Stepped, Conical and Domed Cups: The stepped cups are produced in two or more stages by deep drawing operation. In first stage, a cup is drawn to have the large diameter. In second stage, a redrawing operation is performed on only the lower portion of the cup.
In the same way, conical and tapered cups cannot be drawn directly. During the deep drawing process, different stress conditions result in the material.
Figure 2 shows a drawn cup with the different loading zones. The zones of interest are the flange, the side wall (cup wall), and its bottom. The stress condition in the flange area is a tensile load in radial direction and compression load in tangential direction.
Draw Ratio: The draw ratio is the depth of the part divided by the narrower of width or length. In general the draw ratio should be restricted to Deeper draw ratios can sometimes be accomplished utilizing special forming techniques. Undercuts: An undercut is an area of negative draft. This creates an area where during the forming.
Draw Ratio = If the desired ending wall thickness is ” use the draw ratio value as follows: x ”” starting gauge. Assuming perfect material distribution. The above examples ignore the effect that a specific feature on the part (i.e.
a localized severe draw like a sharp corner) may have on the thinning of the sheet.Deep drawing is a sheet metal forming process used industrially to produce cup-shaped, box-shaped, and other complex-curved hollow-shaped sheet parts. Micro-cups/micro-boxes may be produced with similar process configurations (Figure 7) for micro-housing applications, such as for the packaging of micro-sensors and micro-actuators.
