china's steel-plastic steel pipes have not been developed for a long time, and there is still a large gap compared with foreign countries in raw materials, technology, manufacturing equipment, and other aspects. for example, coating on the outer wall of the pipeline can increase the circuit resis

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 div

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

the hazard of incomplete penetration of the plastic-coated steel pipe is that the effective area of the weld is reduced, and the plastic-coated steel pipe reduces the joint strength.secondly, the harm caused by the stress concentration caused by incomplete penet

advantages of plastic-coated steel pipe1. hygienic, non-toxic, no fouling, no breeding of microorganisms, ensuring fluid quality2. resistant to chemicals, soil and marine organisms, cathodic disbonding3. the installation process is mature, convenient, and fas

anti-corrosion steel pipe is a common steel pipe. to slow down and prevent the corrosion and depreciation of the steel pipe under the chemical and electrochemical action of internal and external media, or due to the metabolism of microorganisms, it is necessary to do a good job o

1.ipn8710 anti-corrosion steel pipe. when there are many types of corrosive media in the steel pipe, such as acid, alkali, salt, oxidant, and water vapor, the coating must be chemically inert and resistant to acid, alkali, and salt corrosion. the coating film should have a dense

steel pipe coating anti-corrosion is an average dense coating formed on the surface of the rust-removing metal pipe, and its coating can isolate it from various corrosive media. steel pipe anti-corrosion coatings are increasingly using composite materials or composite structures. these materials

introduction to the large-diameter anti-corrosion steel pipe1. all steel pipes should be de-rusted on the steel plate on the inner wall of the large-diameter steel pipe before processing, and the metal should be exposed to metallic luster (whitening). it should meet the sa

the construction of cement mortar fabric should usually be carried out after the spiral steel pipe is laid, the pressure test is qualified, and the soil is compacted according to the planning requirements. due to the small rigidity and thin wall of the steel pipe, the pipeline mu
