Key points and advantages of plastic-coated steel pipe construction and installation


plastic coated steel pipe construction

1. it should be implemented by cecs125:2001 of "technical regulations for building water supply plastic-coated composite pipe pipeline engineering".

2. the following construction equipment should be used for plastic-coated steel pipes:

(a) cutting shall be made with a metal saw;

(b) a special rolling groove machine should be used for the pressure groove;

(c) the bent pipe should be cold-formed by a pipe bender;

(d) electric threading machine should be used for pipe thread processing;

(e) the deburring of the plastic-coated steel pipe end and the processing of the corner should be processed with a file;

(f) a small brush or a small toothbrush should be used to apply high-strength inorganic solvent liquid epoxy resin coatings.

3. the construction procedure of plastic-coated steel pipes should meet the following requirements:

(a) plastic-coated steel pipes should not be embedded in reinforced concrete structural layers;

(b) welding is prohibited in the installation of plastic-coated steel pipes;

(c) the installation of plastic-coated steel pipes should be gradually connected from large diameters too small diameters, and the pipe openings should be blocked in time;

(d) plastic-coated steel pipes are strictly prohibited from throwing and violent impact during transportation, loading, unloading, and construction on the construction site;

(e) when installing plastic-coated steel pipes, pipe benders can be used for cold bending when the pipe diameter is not greater than dn50, but the bending radius of curvature shall not be less than 8 times the pipe diameter, and the bending angle shall not be greater than 10°.

advantages of plastic coated steel pipe

1. hygienic, non-toxic, no fouling, no breeding of microorganisms, ensuring fluid quality

2. resistant to chemicals, soil and marine organisms, cathodic disbonding

3. the installation process is mature, convenient, and fast, and the connection is the same as that of ordinary galvanized pipes

4. good weather resistance, suitable for harsh environments such as deserts and saline alkalis

5. smooth pipe wall, improved conveying efficiency, and long service life
