1
Q

What are drawings and blueprints in the piping industry?

A

Drawings and they’re blue print copies are the principal language used to convey piping information from engineers and designers to the fabrication and construction personnel.

2
Q

What are lines in drawings and blueprints used for?

A

Piping in blueprints is generally represented by a solid line, but when it is necessary to differentiate between the dissimilar lines of pipe lettering and symbols are often used.

3
Q

Describe a break line.

A

Three types of brake lines are frequently used on drawings to shorten continual long objects. The short brake line is used on a break is required across a small space. Is represented by a thick wavy line. The long brake line is drawn then with a horizontal Z. between the line showing the break. For round objects or pipe, I thick S break is usually used.

4
Q

Describe the centerline.

A

I thin line composed of long dashes is alternating was short dashes is used to represent the centre of fittings, pipe and equipment.

5
Q

Describe a cutting plane line.

A

I think line used to indicate where a difficult to show object or section of the drawing is cut through for viewing. A drawing of the view is than shown through the cut plane, typically distinguished by sectional letters.

6
Q

Describe dimension and extension lines.

A

Thin lines that are typically used together to represent the extended features of an object and the dimension of those features. Dimension lines typically use arrowheads placed against extension lines to limit or show the dimension features.

7
Q

Describe flow lines.

A

Primary and secondary flowlines are used on floor diagrams and PE and ID drawings to show flow paths. Primary liens are shown as thicker lines and secondary lines as medium to thick lines.

8
Q

Describe hidden line.

A

Medium weight dash lines used to show features hidden from the particular view of a drawing

9
Q

Describe match and boundary lines.

A

I think line use the show where two drawings align our project boundaries began.

10
Q

Describe objects or visible line.

A

Continuous line used to represent all visible objects surfaces that are in view.

11
Q

Describe section line.

A

Medium or thin weight lines usually drawn at 45° indicate the object or surface has been cut through along this point or plane. The nature of material used in the object can be identified by the types of crosshatching line used and showing the cut surface.

12
Q

Describe phantom line.

A

I thin line consisting of long dashes as alternating with a pair of short dashes the phantom line indicates: alternating positions or moveable parts, future location of equipment or piping. And/or repeated detail.

13
Q

Pipe and fitting representation: pipe and fittings are shown on drawings and blueprints in two styles what are they?

A

Single line. Double line.

14
Q

Why do most drawings and blueprints use the single line method?

A

Faster to draw showing pipe and fittings.

15
Q

When are double line drawing usually used?

A

I’m pipe sizes over 12 inches and where is important so the Clarence or relationship between lines and/or equipment.

16
Q

line identification numbers and their location.

A

Line identification numbers or codes are used in industry to differentiate between the various pipe runs through the system. The line number is typically placed beside the line or located directly in the pipe line drawing.

17
Q

Are line identification numbers standardized?

A

No. Even though the line identification codes are not standardized, most companies provide the same fundamental information within each line number.
