Abstract
The utility model relates to a steel pipe coated with an antiseptic coating of acrylic polyurethane in high temperature, which is composed of a steel pipe, a reserved welding section, an inner anticorrosive coating, a zinc rich epoxy primer layer, an epoxy iron coating and an outer anticorrosive coating of the acrylic polyurethane, wherein the outer anticorrosive coating of the acrylic polyurethane has good weather resistance and corrosion resistance, and can do maintenance for coating a layer again when the surface temperature of a pipe fitting is up to 70 DEG C. Thus, a coating with good surface appearance is obtained. The utility model has the advantages of simple production process and high performance-price ratio, and can be used for overhead pipelines.
Description
Technical field
The utility model relates to a kind of high temperature coated acroleic acid polyurethane outer anti-corrosive coating steel pipe, is used for high temperature oil, gas aerial pipeline.
Background technique
Existing high temperature oil, gas aerial pipeline adopt synthetic resin outer anti-corrosive coating steel pipe, its deficiency is that outer anti-corrosive coating contains more bubble, and the apparent property of coating is poor, influences ornamental and antiseptic effect, in addition, at high temperature be not easy to carry out the coating maintenance of outer anti-corrosive coating.
The model utility content
The technical problem to be solved in the present invention: avoid above-mentioned deficiency of the prior art and provide that a kind of manufacture method is simple, cost is low, its coating has good corrosion protection and decorate properties, particularly when the steel tube surface temperature reaches 70 ℃, carry out the high temperature coated acroleic acid polyurethane outer anti-corrosive coating steel pipe of the coating maintenance of outer anti-corrosive coating.
The technical solution adopted in the utility model
High temperature coated acroleic acid polyurethane outer anti-corrosive coating steel pipe 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 acroleic acid polyurethane 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 acroleic acid polyurethane outer anti-corrosive coating 6 is 0.03～0.1mm.
The steel pipe of more excellent high temperature coated acroleic acid polyurethane 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 acroleic acid polyurethane outer anti-corrosive coating 6 is 0.08mm.
