Material, compared with general rustless steel, other corrosion resistant metals, nonmetallic materials, (includes electrochemical corrosion at various corrosive environments
And chemical attack) in, there is the ability of stronger corrosion-resistant (including general corrosion, local corrosion and stress corrosion etc.),
And having good mechanical property and processing characteristics concurrently, its comprehensive corrosion resisting property will be far better than rustless steel and other corrosion resistant metals
Material.Inner liner stainless steel also has stronger decay resistance, and cost is relatively low.
Further, nonmetal anticorrosive coat is resin bed, has antiseptic power strong, and adhesive force is strong, hardness is high, wear-resisting, resistance to
Salt fog, acid and alkali-resistance, gloss are high, solid content high, richness advantages of higher, it is to avoid between resin bed and steel pipe inner wall due to
The combination that bigger volume deformation or variations in temperature cause loosely phenomenon.Preferably, resin bed is epoxy resin layer.
Further, nonmetal anticorrosive coat of the present utility model is provided with annular covering part, can by nonmetal anticorrosive coat with
It is firmly bonded between anti-corrosion of metal layer, it is to avoid the junction of nonmetal anticorrosive coat and anti-corrosion of metal layer goes wrong the tubing caused
Matrix corrosion.The region of the anti-corrosion of metal layer covering annular covering part is passed through at shot-peening or electric angle grinder craft hacking and cleaning
Carry out annular after reason again and cover spraying formation annular covering part, be beneficial to improve bonding force.
The composite anti-corrosive structure of anticorrosion multiple tube of the present utility model, inner wall smooth, fluid resistance is little, and stability is high, tool
Having special anticorrosion, Wax proofing, drag reduction, the performance such as energy-conservation, it both can guarantee that pipe interior had the decay resistance of excellence,
