features of inner and outer plastic-coated steel pipes: inner and outer epoxy resin-coated steel pipes are steel-plastic composite pipes made of welded steel pipes as the base material, and sandblasting chemical double pre-treatment, preheating, inner and outer coating, curing, a

plastic-coated steel pipe is a new type of pipeline material recently developed in china. it adopts a composite structure with a plastic-coated protective layer inside and outside, and a reinforced welded steel pipe or seamless pressure-bearing steel pipe in the middle, which ove

advantages of outer polyethylene inner epoxy resin coated steel pipe:1. it has high mechanical strength and is suitable for harsh environments;2. the inner and outer coatings can prevent metal oxidation and have good chemical corrosion resistance;3. the coati

precautions for the use of plastic-coated steel pipes and analysis of connection and installation: metal saws or threading machines should be used for extrusion cutting and gas cutting to avoid excessive temperature and the strong extrusion during cutting, which will melt and def

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 composite steel pipes usually refer to double-sided plastic-coated pipes, also known as plastic-coated steel pipes on the outside and inside. for composite steel pipes, the early de-rusting technology plays a vital role in the quality of the finished pipe. therefor

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-corro

the detection of plastic-coated steel pipes has always been an important existence for us. given the existing conditions, the following inspections and tests are often carried out by us:appearance inspection: visually inspect the appearance quality of the coated steel pip

the powder in the plastic-coated steel pipe is a kind of epoxy resin powder, so what are the characteristics of this epoxy resin powder? what is the role of plastic-coated steel pipes?epoxy resins generally refer to organic polymer compounds containing two or more epoxy g

the coating methods of plastic-coated steel pipes for large-diameter water delivery are divided into two categories: internal coating and external coating at the same time, and internal coating and external coating separately.process coating methods are also divided into

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 cost is higher th

1. distinction in use:plastic-lined steel pipes are usually divided into plastic-lined steel pipes for cold water and plastic-lined steel pipes for hot water;plastic-coated steel pipes are usually divided into plastic-coated steel pipes for water supply and plastic-coated st

1. meet the service life requirements. considering the purpose of use, new pipes, especially plastic pressure pipes, should first consider the service life rather than the allowable load, because the pipe itself is a permanent structure, and its service life should be consistent with the service

application range of plastic coated steel pipe(1) coal mine system: underground water supply and drainage, fire sprinkler, underground grouting, positive and negative pressure ventilation and gas drainage, and other pipe networks.(2) heating network water delivery system:

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

1. the plastic-lined composite steel pipe is made of thermoplastic pipes such as polyethylene (pe), heat-resistant polyethylene (pe-rt), and cross-linked polyethylene (pe-x) lining the inner wall of the steel pipe according to the requirements of the conveying medium. , so it has the advantages o
