plastic-coated steel pipes are based on welded steel pipes and seamless steel pipes, and the inner and outer walls are coated with epoxy resin or polyethylene powder. they are anti-corrosion, corrosion-resistant, non-toxic, and non-radiative green environmental protection pipes,

epoxy resin coated steel pipe coating is a thermosetting plastic, which combines the common advantages of steel and plastic, and its scope of application includes:1. fire sprinkler system and domestic water supply and drainage;2. gas drainage, mud transportation, and

what they have in common is that they all belong to inner and outer plastic coated steel pipes, but fire-fighting plastic coated steel pipes are only one category of inner and outer plastic coated steel pipes.we are already familiar with the plastic-coated composite steel

when using fire-fighting plastic-coated steel pipes, you will understand the implemented standards. what are the special requirements and circumstances of these standards? the detailed details are introduced below.anti-corrosion, food-grade hygienic thermoplastic powder c

1. appearance inspection: check the appearance quality of plastic-coated steel pipes.2. thickness measurement: take two cross-sections of different lengths from both ends of the plastic-coated steel pipe, and use an electromagnetic thickness gauge to measure

first, the characteristics of fire-fighting plastic-coated steel pipes:1. hygienic, non-toxic, no fouling, no breeding of microorganisms, ensuring fluid quality.2. the flame retardant ability is strong. under the combustion test, the coating has no spontaneous combu

plastic-coated steel pipe has the dual advantages of steel pipe and plastic pipe. it not only has the mechanical strength and bearing pressure of steel pipe, but also has the characteristics of the smooth inner wall of the non-metallic pipe, strong wear resistance, strong corrosi

plastic coated steel pipes, also known as plastic-coated pipes, steel plastic composite pipes, and plastic-coated composite steel pipes, use steel pipes as the substrate, and weld a layer of plastic anti-corrosion layer or steel-plastic composite steel pipe with plastic anti-corr

in recent years, the status of ordinary steel pipes has declined rapidly. the fundamental factor is that the environment is severely corroded. even if the wall thickness of steel pipes is large, it is always unrealistic to use wall thickness to slow down corrosion, because the wall layer of steel

1. epoxy coal tar pitch anti-corrosion coated layera. epoxy coal tar pitch anti-corrosion coating is suitable for anti-corrosion on the outer wall of buried steel pipelines for transporting oil, water, and gas, and the temperature of the transport medium is required to be lower than or equ

1. plastic-coated steel pipe cuttingmetal saws should be used for cutting plastic-coated steel pipes, and sawing machines should be used for large-diameter pipes. when using entrenched cutting, the speed should not exceed 800r/min; the section of the pipe to be cut should

the inner and outer walls of plastic-coated steel pipes are coated with epoxy resin, the surface is smooth, the fluid resistance is reduced, the flow rate is increased, no scale is formed, and microorganisms generally do not grow. the service life of the fire water supply (gas) p

plastic-coated steel pipesplastic-coated steel pipes, also known as plastic-coated steel pipes, steel-plastic composite pipes, and plastic-coated composite steel pipes, are based on steel pipes, and use pe (modified polyethylene) for hot dipping or ep (epoxy resin) as the

the anti-corrosion of plastic-coated steel pipes has developed from the earliest inner and outer polyethylene, due to adhesion problems, to inner and outer epoxy, but the outer epoxy layer is not resistant to bumps, and later developed to the third generation of inner epoxy outer

1. 3pe anti-corrosion steel pipe has high sealing performance, and long-term operation can greatly save energy, reduce costs and protect the environment.2. strong corrosion resistance, simple and fast structure, and service life can reach 30-50 years.

3pe anti-corrosion steel pipe is a more advanced anti-corrosion technology in recent years. its full name is the fusion bonded epoxy/extruded polyethylene structural protective layer. the structure of 3pe anti-corrosion steel pipe is composed of the following three layers: the bo

the industry standard sy/t0413-2002 does not stipulate the uniformity of the thickness, it stipulates the minimum thickness value of the coating, but it is required that the minimum thickness value of the coating cannot be lower than the thickness value of the low point, not the value of multiple
