Abstract
The utility model relates to a weather resistant anti-outer corrosion coating steel pipe, comprising an inner anti-corrosion coating, a zinc rich epoxy primer coating, an epoxy meteoric iron coating, an outer fluorocarbon anti-corrosion coating and a pre-reserved welding section. The outer fluorocarbon anti-corrosion coating has excellent weather resistance, corrosion resistance and contamination resistance, in particular the weather resistance. The manual accelerated aging experiment can obtain 5000h. The manufacture technology is simple and the price ratio is high. The utility model can be used for overhead pipeline.
Description
Technical field
The utility model relates to a kind of steel pipe of weather resistant outer anti-corrosive coating, can be used for oil, gas aerial pipeline.
Technical background
Existing oil, gas aerial pipeline adopt the coating of synthetic resin coating, and its deficiency is not good, easy to change, the easy efflorescence of weatherability, and stain resistance is bad, and artificial accelerated aging test is 1000h.Existing employing reinforcement polyethylene external protection coating, its thick coating, construction inconvenience, the expense height, easily aging, weatherability is poor, and stain resistance is bad.
The model utility content
The technical problems to be solved in the utility model: avoid above-mentioned deficiency of the prior art and a kind of easy construction be provided, have excellent weather resistance, the steel pipe of corrosion resistance, weather resistant outer anti-corrosive coating stain resistance, that in artificial accelerated aging test, reach 5000h.
The technical solution adopted in the utility model
The steel pipe of a kind of weatherability outer anti-corrosive coating of the present utility model, by steel pipe 1, the reservation welding section 2 at steel pipe 1 two ends is formed, it is characterized in that anticorrosive coat 3 in steel pipe 1 internal surface has, outer surface at steel pipe 1 has epoxy zinc rich primer layer 4 in turn, epoxy micaceous iron coating 5 and fluorine carbon outer anti-corrosive coating 6, steel pipe 1 long 12～24m, external diameter of pipe 100～300mm, wall thickness 5～20mm, reserve each long 100mm of welding section 2 every ends, the thickness of interior anticorrosive coat 3 is 0.2～0.5mm, the thickness of epoxy zinc rich primer layer 4 is 0.04～0.1mm, the thickness of epoxy micaceous iron coating 5 is 0.05～0.1mm, and the thickness of fluorine carbon outer anti-corrosive coating 6 is 0.03～0.1mm.
The steel pipe of more excellent weather resistant outer anti-corrosive coating, it is characterized in that steel pipe 1 long 12m, external diameter of pipe 159mm, wall thickness 10mm, the thickness of interior anticorrosive coat 3 is 0.3mm, the thickness of epoxy zinc rich primer layer 4 is 0.05mm, the thickness of epoxy micaceous iron coating 5 is 0.1mm, and the thickness of fluorine carbon outer anti-corrosive coating 6 is 0.08mm.
The steel pipe manufacture process of weather resistant outer anti-corrosive coating of the present utility model is as follows: with internal surface, the outer surface derusting by sandblasting of steel pipe 1, anticorrosive coat 3 in the internal surface spraying of steel pipe 1, can use anti-corrosive paint of epoxy resin to form coating, outer surface at steel pipe 1 sprays epoxy zinc rich primer layer 4 in turn, epoxy micaceous iron coating 5 and fluorine carbon outer anti-corrosive coating 6.With the steel pipe scene of being transported to of above-mentioned prefabricated weather resistant outer anti-corrosive coating weld, construction such as repaired mouth becomes pipeline.
Fluorine carbon outer anti-corrosive coating 6 is to form coating by the made coating of the curing agent of the PIC mixed solution of the mixed solution of CTFE fluorocarbon resin and isocyanate trimerization structural reform through the spraying normal temperature cure.This coating has good weatherability, corrosion resistance, stain resistance, weatherability especially, and artificial accelerated aging test can reach 5000h.
The utility model beneficial effect compared with prior art:
1, the steel pipe of weather resistant outer anti-corrosive coating, have good interior corrosion protection, outer corrosion protection, outer barrier propterty, fluorine carbon outer anti-corrosive coating 6 has good chemical resistance, stain resistance, especially has excellent weatherability, and artificial accelerated aging test can reach 5000h.
2, production technology is simple, price performance good, can be used for oil, gas aerial pipeline.
