Epoxy powder anti-corrosion steel pipe coating is evenly and densely coated on the surface of the derusted metal pipe to isolate it from various corrosive media. It is the basic method of pipeline anti-corrosion. The pipeline is laid in the middle, and the temperature of the pipeline is increased due to the heating and transportation of oil products, which puts forward more requirements on the coating performance. Therefore, pipeline anti-corrosion coatings are increasingly using composite materials or composite structures.
1. Anti-corrosion coating on the outer wall: the type and conditions of use of the coating material on the outer wall of the pipeline.
②Inner wall anti-corrosion coating: a film applied to the inner wall of the pipe in order to prevent corrosion in the pipe, reduce frictional resistance, and increase the throughput. Commonly used coatings are amine-cured epoxy resin and polyamide epoxy resin, and the coating thickness is 0.038 to 0.2 mm. In order to ensure that the coating is firmly bonded to the pipe wall, the inner wall of the pipe must be surface treated. Since the s, the same material has been used for the coating of the inner and outer walls of the tube, so that the coating of the inner and outer walls of the tube can be carried out at the same time.
③Anti-corrosion and thermal-insulation coating: In order to reduce the heat dissipation from the pipeline to the soil on the medium- and small-diameter heat-transporting crude oil or fuel oil pipeline, a composite layer of thermal insulation and anti-corrosion is added to the outside of the pipeline. The commonly used thermal insulation material is rigid polyurethane foam, and the applicable temperature is -185 to 95 °C. This material has a soft texture. In order to improve its strength, a layer of high-density polyethylene is applied outside the insulation layer to form a composite material structure to prevent groundwater from seeping into the insulation layer.

Epoxy powder anti-corrosion steel pipe for natural gas pipeline

Anticorrosion and heat preservation steel pipe is a kind of steel pipe that can increase the temperature of anticorrosion and heat preservation. It is often used in people’s daily life and has been widely accepted and used by people. Anti-corrosion insulation steel pipe is widely used in construction, decoration and laying of anti-corrosion pipelines, which can ensure the normal and unobstructed pipelines.

The composition of the anticorrosion and heat preservation steel pipe is relatively simple, and its composition is relatively simple, which can make people understand and imagine easily. Anti-corrosion and heat preservation steel pipe is a kind of high-density polyethylene outer sheath polyurethane foam, which is made by tightly combining a steel pipe for conveying medium, a high-density polyzene jacket pipe, and a polyurethane rigid foam insulation layer filled between the steel pipe and the jacket pipe Plastic prefabricated buried steel pipe. Just put the rust-proof and anti-corrosion steel pipe in a polyethylene sleeve, and inject polyurethane in the middle

Foam makes it fully fill the gap between the steel pipe and the polyethylene casing, and finally forms a solid whole of the steel pipe, casing, and insulation layer, and achieves the effect of anticorrosion and heat insulation, and the anticorrosion and heat insulation steel tube is formed.

The anticorrosion and heat preservation method of the anticorrosion and heat preservation steel pipe can be overhead or buried underground. The entire application process can be performed on site, which is convenient for construction and operation, and is easy to be controlled by the construction personnel, and the process is relatively simple.
