In addition, its abrasion resistance, impact resistance and aging resistance are also excellent, which can meet the requirements of use in various complex environments.
3.Wide range of applications.
The polyethylene anticorrosive steel pipe with a diameter of 219 is widely used in petroleum, chemical, natural gas and other industrial fields. In these fields, pipelines often need to withstand harsh environments such as high temperature, high pressure, corrosion, etc., and the epoxy outer polyethylene anti-corrosion steel pipe with a diameter of 219 can effectively solve these problems.
Second, the production process of epoxy polyethylene anticorrosive steel pipe with a diameter of 219.
The production process of epoxy outer polyethylene anticorrosive steel pipe with diameter 219 mainly includes the following steps:
1.Steel cutting.
The steel is cut to the desired length and size, and surface treatment is applied to remove oil and impurities from the surface.
2.Preparation of epoxy resin coatings.
Epoxy resin, curing agent, filler and other raw materials are mixed in a certain proportion and stirred evenly to make epoxy resin coatings.
3.Preparation of polyethylene material.
Polyethylene granules and other additives are mixed in a certain proportion, heated and melted to make polyethylene materials.
4.Livery. After the surface treatment of the steel, a layer of epoxy resin coating is applied before the polyethylene material is wrapped. During the coating process, it is necessary to pay attention to the thickness and uniformity of the coating to ensure the anti-corrosion effect.
5.Heat curing.
The coated steel pipe is fed into the heating furnace and heated and solidified at a certain temperature for a certain period of time, so that the epoxy resin coating and polyethylene material are fully combined to form a solid anti-corrosion layer.
6.Cooling and packing.
The heat-cured steel tubes are cooled to room temperature and packaged for subsequent use.
3. Application scope and prospect of epoxy polyethylene anticorrosive steel pipe with a diameter of 219.
Diameter 219 inner epoxy outer polyethylene anticorrosive steel pipe is widely used in petroleum, chemical, natural gas and other industrial fields because of its excellent anti-corrosion performance and good mechanical properties.
