Title: phosphorus chemical steel rubber composite pipe
Category: phosphorus chemical pipeline
An industry: chemical equipment
The phosphorus chemical special steel rubber composite
pipe is based on ordinary carbon steel pipe as the matrix,
lined chemical stability excellent thermoplastic tube,
cold-drawn composite or rotational molding, it has both the
mechanical properties of the steel pipe, but also the
resistance of the plastic pipe corrosion, slow scale,
less growth and microbial characteristics, pipeline
transport acid, alkali, salt, corrosive gases and other media.
First, the technical characteristics of the pipe lining
material and Scope:
1, PO, PE plastic-lined pipe: use temperature of 80 ° C
or less, suitable for general corrosive medium.
PP plastic-lined pipe: use temperature ≦ 100 ° C,
suitable for corrosive media containing a small
amount of solvent.
F4 lined PTFE pipes: ≦ 120 ° C strong corrosive
medium for conveying.
PU polyurethane lining pipe: excellent wear
resistance, suitable for conveying non-corrosive
mortar within the 70 ° C temperature.
For example: lime slurry, coal slurry, the slurry.
