Introduction 1.1
Purpose The purpose of this Practice is to provide instruction and/or direction to designers for preparation of the Vessel Drawing/Data Sheet. The Vessel Drawing/Data Sheet, prepared in conjunction with PIP VECV1001, PIP VESV1002 and PIP VEFV1100 completes a specification suitable for obtaining comprehensive bids and subsequent purchase of pressure vessels.
1.2
Scope This Practice identifies information to be placed on the PIP “Vessel Drawing/Data Sheet”.

Use of This PIP 3.1
Vessel Drawing/Data Sheet The Vessel Drawing/Data Sheet is an element of a complete pressure vessel specification. This form provides preprinted line items to be completed and includes space for drafting and dimensioning of appropriate views.
3.2
Design Data The preparer should have pressure vessel design experience and ensure the work is both accurate and complete. The preparer should avoid supplying information that is not needed.
3.2.1
Entering Text All text placed on the Vessel Drawing/Data Sheet shall be of size and quality to be readable and reproducible in reduced size including the use of microfilm.

3.2.2
Entering Data Each numbered line of the Vessel Drawing/Data Sheet should be (1) properly filled in or (2) marked NA (Not Applicable). It is suggested that lines be left blank if the information is not known at the time. Lines not completed indicate the “form” is not complete. See Section 4.1 for descriptions and references.
3.2.3
Additional Data Additional information that may be required, that does not have a preprinted line, can be added in the General Notes area of the Vessel Drawing/Data Sheet, or equipment supplier information may be forwarded to the vessel manufacturer such as nozzle loading of agitators.
3.3
Vessel Drawing/Data Sheet It is intended that drawings be placed on the Vessel Drawing/Data Sheet by CAD through electronic media. If CAD cannot be used, then a preprinted Vessel Drawing/Data Sheet should be used. If the quantity of detail views is such that the form becomes cluttered or difficult to use, separate additional sheets, (not preprinted), may be used. These separate sheets should have an appropriate border and title block. All sheets must have suitable identification to be unmistakably kept together. Redundancy of dimensions, notes, and references should be avoided.
3.3.1
Drawing Views Drawing views in general should be orthographic and include “Plan and Elevation” for vertical vessels; “Elevation and End” or “Elevation and Plan” for horizontal vessels. Other views may be added.
3.3.2
Drafting Practices Drafting practices shall be consistent with the following items: a. It is recommended that drawings be made to scale. If not to scale the approximate proportion should be maintained. b. Bottom views are allowed only to describe complex geometry and must be identified. c. North arrow is to be pointing upward on the drawing. d. “0” degrees orientation shall be plant or unit north, whichever applies. e. Showing of component thickness, head/shell etc., is optional. f.
Establish a reference line for tail dimensions. Use a head tangent line or face of flange if vessel has a flanged end.
g. Show supports. h. Show location of legs, lugs, clips, etc. i.
Process Industry Practices
Identify and locate needed internal details. Provide only enough detail to describe the item or provide reference to a PIP Standard Detail. See PIP VEFV1100.

Itemize external attachments such as: name plate bracket, platform and ladder brackets/lugs, pipe supports and guides, davits, supports, anchor chairs, and lifting attachments. Provide reference numbers to applicable PIP VEFV1100, details.
k. Locate support saddles including; dimension from head tangents to center line of the saddles, elevation from the vessel centerline to the bottom of the base plate, and elevation from grade if available. Identify which saddle is to have slotted mounting holes and if a slide plate is required. l.
Provide the skirt height dimension from the bottom of the base plate to the head tangent. Provide the type and quantity of anchor chairs. Include the bolt circle and location of anchor bolt holes (or chairs). Anchor bolt and chair locations should straddle normal centerlines.
m. Show location and orientation of hinges and davits.
3.3.3
Connection Schedule The “Connection Schedule” is located on the Vessel Drawing/Data Sheet. a.
Mark: Enter the identification of the opening in this column. Use “N” for nozzle, “C” for coupling, “M” for manway, and “SO” for skirt opening. The format is: N-1, etc. Multiple openings that have identical descriptions, such as level gauges, may have the same identification with the addition of a letter suffix and the format is: N-1 with the quantity given in the “No. Req'd” column, and shown on the drawing as N-1A, N-1B, and so on.
b. No. Req'd: Enter the quantity of openings that will have a common Mark as described in (a). c.
Size: Enter the NPS (Nominal Pipe Size) of the opening.
d. Rating: Enter the ASME/ANSI flange class. For ASME B16.47 specify “A” or “B”. e. Facing: Enter the flange facing e.g. RF, FF, RJ etc. f.
Center Line Projection: Enter the dimension from the centerline of the vessel to the face of the flange, or the dimension from reference line to face of flange for head openings.
g. Description: Enter identification of service for the opening. Include blind flanges and covers to be furnished with the vessel.
3.3.4
References and Revisions The “Reference Specifications/Drawings” and “Drawing Revisions” blocks are along the bottom margin of the Vessel Drawing/Data Sheet. The information required is commonly understood and not identified further in this description.

Definition of Vessel Drawing/Data Sheet Lines This section provides guidance for completion of each numbered line on the Data Sheet.
4.1
Design Data The following numbered items (1 through 26) correspond to the numbered lines on the Vessel Drawing/Data Sheet. Basic action required and references are provided. See Section 2.1 of this document for reference information. Action/References
