7. Pipeline installations
7.1) Pipeline facture
7.1.1 The material of the pipeline
Standard: lubricity inside; small friction resistance; not absorbing moisture; incombustibility;
erosion resistance; longevity; lightness; good sealing; no accumulation; easily cleaning. Normally,
we can select galvanization steel, aluminum, and plastic. For short pipeline, we can also select
aluminum foil board.
7.1.2 The process of the piping
The process of the piping should meet the requirements of the design. The process can be
done in subsection. And every subsection’s length is about between 1.8m and 4m. In order to
improve the pipeline’s rigid, a rib often be added at the outer surface. The pipeline usually
adopts the flange to connect and add the asbestos washer with thickness 3mm to prevent air
leakage. At present, the sealant and adhesive tape are also used to seal.
7.1.3 The shape of the pipeline
7.1.3.1 Type of the pipeline
The pipeline has ground and directs shape. The compare is as follows:
Ground pipeline
Square pipeline
less material, need large space, its’ bending
pipe and three-way pipe need long distance
need small space, can be equipped easily, adopt
direct pipeline with the rate below 2.5 between
length and width
7.1.3.2 Specification of the pipeline
Ground pipeline should first adopt the basic series; the ratio of the long side and the short
side of the direct pipeline should not be larger than 4:1. Pipeline should be outer diameter or
outer border. Brick and concrete pipeline should be inner diameter or inner border.
