Abstract
The utility model provides a corrosion-resistant steel pipe applicable to an ocean environment to solve the problems of short validity period, easiness in aging and poor weather resistance of an existing ocean environment steel pipe. The corrosion-resistant steel pipe comprises a steel pipe body, reserved welding sections are arranged at two ends of the steel pipe body, an inner corrosion protection coating is arranged on the inner wall of the steel pipe body, weldable coatings are arranged on the outer walls of the reserved welding sections, and a corrosion protection primer coating, an epoxy micaceous iron oxide intermediate paint coating, a high solid intermediate coating and a corrosion-resistant coating are sequentially arranged on the outer wall of the steel pipe body. The corrosion-resistant steel pipe has excellent inner corrosion protection, outer corrosion protection and outer protection performances, a polyurethane finishing coat has excellent chemical corrosion resistance and weather resistance, and the corrosion-resistant steel pipe is simple in production technology and can be widely used for ocean platform overhead pipelines and offshore wharf ground pipelines.
Description
Technical field
The utility model belongs to offshore engineering equipment, particularly a kind of steel pipe.
Background technique
At present, for the anti-corrosion protection of ocean environment steel structure, the general method that adopts coating anticorrosive coat.Require the protection period of anticorrosive coat in 15～20 years.And design according to this design philosophy, in selection and construction, be rigid in checking up, just can reach the long-effective protection to ocean environment steel structure.
Existing steel pipe, although coating has premium properties and the good anti-seawater corrosions such as salt spray resistance, resistance to bacterium, once occur that coating breaks, corrosion spreads very fast its Long Service Life that affects.
The shortcomings such as current ocean environment steel pipe exists effective date shorter, easily aging, and weatherability is poor.
Model utility content
The purpose of this utility model is to provide a kind of corrosion-proof steel pipe that is applicable to ocean environment, to solve existing ocean environment steel pipe, exists effective date shorter, easily aging, the problem that weatherability is poor.
The utility model is by the following technical solutions:
A kind of corrosion-proof steel pipe that is applicable to ocean environment, comprise steel pipe body, steel pipe body two ends are provided with reserved welding section, the inwall of steel pipe body is provided with inner anticorrosioning coating, reserved welding section outer wall is provided with can welding coating, and the outer wall of steel pipe body is provided with anti-corrosion primer coating, epoxy micaceous iron intermediate coat coating, high solid floating coat, wear resistant coating successively.
The thickness of inner anticorrosioning coating is 0.3～0.5mm; The thickness of anti-corrosion primer layer is 0.07～0.08mm; The thickness of epoxy micaceous iron intermediate coat coating is 0.06～0.08mm; The thickness of high solid floating coat is 0.1～0.12mm; The thickness of wear resistant coating is 0.08～0.1mm; Thickness that can welding coating is 0.02～0.03mm.
