plastic-coated steel pipe is a coated pipe that not only has good corrosion resistance but also has good electrical insulation and low water absorption, which prolongs the service life of the pipe and achieves the purpose of long-term use.advantages of plastic-coated stee

anti-corrosion plastic-coated steel pipe is a metal body buried in the ground. however, due to the use of the environment, despite careful construction, the general steel pipe will inevitably age easily, and the steel pipe will still be damaged. to prolong the life of the steel pipe, it is necess

is there rust after cleaning the surface of the plastic-coated steel pipe? will the plastic-coated steel pipe rust? will the plastic-coated steel pipe rust under wind and rain conditions? the plastic-coated steel pipe has a smooth appearance, easy cleaning, and corrosion resistan

1. plastic-coated steel pipes are strictly prohibited from being dropped and violently hit during transportation, loading, unloading, and construction on the construction site;2. plastic-coated steel pipes should not be buried in reinforced concrete structural layers;3. t

coating raw materials for plastic-coated steel pipes include epoxy resin (epoxy powder) and polyethylene coating materials. the inner wall of the pipeline is coated with epoxy powder thermal fusion, and the outer wall of the pipeline is generally anti-corrosion with epoxy powder

1. epoxy resin coated steel pipe firstly pre-treats the base pipe.2. sandblasting the steel pipe, the surface of the steel pipe is blasted and de-rusted according to bg/t8923 to sa2 1/2 level, to ensure roughness and improve the adhesion.3. put the sandblasted steel

(1) the dust, oil, scale, etc. on the surface of the epoxy resin-coated steel pipe must be cleaned before painting. reach sa 2.5 level to ensure the quality of the painting. it is strictly forbidden to bring in water during construction.(2) the construction rati

plastic-coated steel pipe for water supply is a new type of pipe specially developed for water supply and drainage. the pipe combines the characteristics of various pipes. it not only has the rigidity and hardness of steel pipe but also has the wear resistance, corrosion resistan

if the interior and exterior are fully coated steel pipe with plastic, no anti-corrosion oiling is required. if the interior is plastic-coated and the outside of the pipe is only used for insulation, no anti-corrosion oiling is required. if the interior is plastic-coated and the

the use of plastic-coated steel pipes in developed countries has been relatively mature. for example, in the water pipes in the united states, japan, and other countries, 80% to 90% of the pipes are plastic-coated steel pipes. the coated steel composite pipe meets the constructio

epoxy resin coated steel pipe coating belongs to thermosetting plastics, which combines the common advantages of steel and plastic, and its scope of application includes1. fire sprinkler system and domestic water supply and drainage;2. ga

how to use plastic-coated steel pipes correctly should be used correctly by the specifications. large-diameter plastic-coated steel pipe is a new type of pipe, which is used in many fields and has many excellent properties, especially its anti-corrosion performance is loved by pe

as we all know, plastic-coated steel pipes can be used not only in the field of water supply and drainage but also in the field of automatic sprinkler fire extinguishing systems, groundwater sewage dredging pipes, central air-conditioning cooling circulating wate

steel structure building materials are materials often used in the construction industry. there are many ways for steel structures to exist, such as steel plates, steel pipes, and so on. to make these pipe fittings play a better role, great scientists have been continuously developing new product

1. weld defects:the weld defects of plastic-coated steel pipes are serious, and manual mechanical grinding is used to make up for them. the resulting grinding marks will cause uneven surfaces and affect the appearance. pickling and passivating only the weld seam also creat

large-diameter plastic-coated steel pipes are mainly made of spiral steel pipes or seamless steel pipes. it is not recommended to use straight seam welded pipes. longitudinal welded pipes are usually not as good in bearing pressure as spiral steel pipes, and the
