Application Areas Of Internal And External Epoxy Plastic Coated Anti-Corrosion Spiral Steel Pipe

Application fields of internal and external epoxy coated anti-corrosion spiral steel pipe:

1, urban large-diameter and small-diameter water pipe, direct drinking water delivery, food pipeline.

2、Pipes used in pharmaceutical, chemical, printing and dyeing industries;.

3、Pipes, cables and communication cables used in marine and offshore engineering;.

4, Chemical water treatment systems, road and river projects.

Oil and gas pipeline, oil field anti-corrosion pipe, fire pipeline, highway pipeline, etc. are the application fields of internal and external plastic coated steel pipe.

Product characteristics of internal and external epoxy plastic coated anti-corrosion spiral steel pipe:

Internal and external epoxy plastic coated anti-corrosion spiral steel pipe has good pressure resistance and good insulation, which can protect the wires and prevent leakage of electricity, and the plastic coated steel pipe is smooth and burr-free, which is suitable for the structure of cables or wires, and it is an upgraded and renewed product of the traditional steel pipe and galvanized steel pipe.

It has certain strength, elongation, corrosion resistance, abrasion resistance, fluid resistance and other characteristics, it is a new type of water supply and drainage, anticorrosion green large-diameter pipe, has been widely used in domestic industry.

Internal and external epoxy plastic coated anticorrosion spiral steel pipe products are characterized by significantly improved adhesion of the coating, impact resistance, pressure resistance, not easily embrittled, to ensure hygiene, non-toxic, non-polluting product quality, good chemical resistance, resistance to soil and marine environment biochemical corrosion.

Plastic coated steel pipe installation process is mature, easy and quick installation, connection method is similar to ordinary galvanized pipe, good weather resistance, high transport efficiency, long service life.

Internal and external epoxy plastic coated anti-corrosion spiral steel pipe production and installation practices should be very careful to ensure the quality of installation:

1, before construction should be carefully familiar with the drawings, according to the construction program to decide the construction methods and technical delivery of specific measures to do the preparatory work. Refer to the relevant equipment drawings and decorative architectural drawings, check the coordinates of a variety of plastic-coated pipes, elevation whether there is a cross, plastic-coated pipe arrangement of the space used is reasonable. Problems with the design and relevant personnel to study and solve, do a good job of change negotiation records.

2, according to the design drawings drawn plastic-coated pipeline branch, diameter, diameter, reserved port, valve position and other construction sketches, in the actual installation of the structural position of the mark, according to the marking of the subsection measurement of the actual installation of the exact size of the record in the construction sketches, and then pre-fabrication processing according to the dimensions of the sketches measured.

3, plastic-coated pipe installation generally from the total into the mouth of the operation, the total inlet end with a good temporary silk plug for pressure testing. Before installation should be pipe, pipe fittings for appearance check: the internal and external surfaces should have a complete galvanized layer, and should be smooth and beautiful, pipe fittings inside and outside the surface should be smooth, no trachoma, no broken threads missing silk phenomenon.

4, internal and external epoxy plastic coated anticorrosion spiral steel pipe connection using threaded connection, set of silk buckle when the destruction of the galvanized layer surface and the exposed part of the thread should be done anticorrosion treatment.

5, the use of threaded connections, plastic coated pipes should be mechanically cut, the cutting surface shall not have flying edges, burrs; cutting, to ensure that the pipe end face vertical. Sleeving should adopt automatic sleeving machine, lubricating oil lubrication, and should use standard thread gauge inspection. When processing, pay attention to the cooling of the pipe body, do not make the pipe hot. Protect the thread after processing.
