3、Old pipeline map:Represents arrangement of connecting pipes between devices。

(brass tube reducer swage)4、Steam noodle system arrangement:When the steam none system is simpler,It can also be represented on the process pipeline arrangement.。

(brass tube reducer swage)5、Non-tube diagram:If you choose standard fittings when designing,Do not need to draw the fitting diagram。The specific dimension of the pipe fittings on the pipe fittings。

6、Non-tube frame:The scaffold is a steel structural bracket used to support the pipe.。In designation, first select from the standard map,If you choose a standard map,No need to draw a drawing figure。

View of pipeline arrangement:

(brass tube reducer swage)1.Regional line、Pipe table and installation direction standard(The orientation is consistent with the device)。

key planUse in pipeline arrangement,Location indicating the location of the design pipe in the entire plane arrangement。

2.architecture:

Draw the basic structure of the building:column、Beam、Floor、door、window、platform、Mounting holes and stairs, etc.;

Control room、Production auxiliary housing such as distribution rooms is generally not expressed。

3.equipment:

Determined by device arrangement,Draw out equipment profile and foundation;If the device shape is symmetrical, you should draw the center line.;

Horizontal equipment draws a mount and marked position,Vertical support should be marked from the position of the human hole skirt。

The fixed device can be drawn according to the illustration,Dynamic equipment plan map can only draw foundation,But draw a driver position。

4.pipeline、valve、Fitting fitting

Pipeline projection drawing:

a)Specific simplified drawing;

b)To expose the length of the pipeline、Valves and fittings。

1)Pipe drawing:DN≤350mm。

(brass tube reducer swage)Main material pipeline:Gross single line

Art style:

(brass tube reducer swage)a)Pipe diameter;

(brass tube reducer swage)b)To draw a central line;

c)Expressing the medium flow in arrows。

2)Pipeline connection

(brass tube reducer swage)The connection of the pipeline is mainly:Welding connection;Flange connection;Thread connection;Insert connection。

Several way of connection:

4)Three-way

There are two types of three-way manufacturing method.:

a)On-site open welding on the pipe;

b)Standard three-way fittings。
