the product implementation standard is based on cj/t120-2008, and the pretreatment grade of the steel pipe and the formula performance of the coating material are improved according to its use requirements. in particular, the expansion coefficient of the coating material is the same as that of th

epoxy powder anti-corrosion coated steel pipe is a steel pipe with polymer coating sprayed on the surface of the steel pipe, which has the characteristics of anti-corrosion, wear resistance, acid and alkali resistance, and anti-aging. the production process generally includes the

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

fusion-bonded epoxy powder anti-corrosion plastic-coated steel pipe first flows fully in the fluidized bed, and then electrostatically sprays to make the powder particles negatively charged, and evenly extends the powder particles to the surface of the preheated grounded steel pi

epoxy powder anti-corrosion coated seamless steel pipe is a product that uses pe (modified polyethylene) for hot dip molding or ep (epoxy resin) for internal and external coating and has excellent corrosion resistance. at the same time, the coating itself has good electrical insu

epoxy powder anti-corrosion coated steel pipe is made of spiral steel pipe fusion-bonded epoxy powder outer coating (fbe/2fbe) a new type of anti-corrosion coating developed in the past 30 years. fbe coating has two types: single layer and double layer. the so-called fbe coating

01. it is used for urban sewer drainage. because the sewer is heavily polluted, the drainage pipes that need to be used have good corrosion resistance, and plastic-coated steel pipes meet this point.02. oil transportation can also be used, as well as gas transportation.03. drainage of the

internal and external epoxy powder anti-corrosion steel pipe plastic-coated steel pipe is now the most widely used steel pipe. it has both the advantages of plastic pipes and steel pipes. new product. plastic-coated steel pipe is a combination of plastic pipe and steel pipe. it can now be used in

fbe epoxy powder anti-corrosion structure: uses an electrostatic spraying process to coat epoxy powder on the surface of the steel pipe to form a film at one time. the coating has the advantages of simple coating operation, no pollution, good impact resistance, and bending resistance, high-temper

plastic-coated steel pipe for water supply is a new type of composite pipe specially developed for water supply and drainage. the composite pipe combines the characteristics of various pipes. it is a green and energy-saving pipe with very high-cost performance due to its small co

epoxy powder anti-corrosion coated steel pipe is a steel pipe with polymer coating sprayed on the surface of the steel pipe, which has the characteristics of anti-corrosion, wear-resistant, acid and alkali resistance, and anti-aging. the production process generally includes the

if the interior and exterior are fully coated 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 outside of the pipe is direc
