Epoxy resin anticorrosive steel pipe is a new type of anticorrosive material, which is made of epoxy resin and polyethylene mixed with high temperature and high pressure. This kind of steel pipe has excellent anti-corrosion performance and durability, and is widely used in petroleum, chemical, natural gas, water supply and drainage and other fields. Inner epoxy outer polyethylene anticorrosive steel pipe
1. Features. 1.Strong corrosion resistance: epoxy resin anti-corrosion steel pipe has strong corrosion resistance, can resist the erosion of a variety of chemicals, especially to acids, alkalis, salts and other corrosive substances have good resistance.
2.Good durability: The epoxy resin anti-corrosion steel pipe adopts a double-layer anti-corrosion structure, with an epoxy resin coating on the inside and a polyethylene coating on the outside, which can effectively protect the steel pipe from the erosion of the external environment and ensure its durability.
3.Convenient construction: The construction of epoxy resin anti-corrosion steel pipe is very convenient, which can be connected by traditional welding, flange connection, etc., and can also be installed by preset slots.
4.Good environmental protection: epoxy resin anti-corrosion steel pipe does not produce any waste gas and waste water in the production process, and has no pollution to the environment. At the same time, its use does not have a negative impact on the environment.
5.Wide range of application: Epoxy resin anti-corrosion steel pipe is suitable for various types of fluid transportation, such as petroleum, chemical, natural gas, water supply and drainage and other fields.
Second, the manufacturing process.
The epoxy resin anticorrosive steel pipe adopts a high-temperature and high-pressure hybrid molding process, which mixes two materials, epoxy resin and polyethylene, together at high temperature and high pressure. The specific steps are as follows:
1.The surface of the steel pipe is polished to remove impurities such as rust and oxide scale on the surface.
2.Mix the epoxy resin and polyethylene material together in a certain proportion and stir well.
3.The mixed material is applied to the surface of the steel pipe and heated to solidify it.
4.The coated steel pipe is treated with high temperature and high pressure to make the two materials fully mixed together.
5.The quality inspection of the finished product is carried out to ensure that its performance indicators meet the requirements.
Third, the field of application.
1.Oil and gas field: epoxy resin anti-corrosion steel pipes are widely used in the oil and gas field, which can effectively protect pipelines from the erosion of various corrosive substances.
2.Chemical industry: epoxy resin anti-corrosion steel pipes are also widely used in the chemical field, which can effectively protect pipelines from the erosion of acids, alkalis and other chemicals.
3.Water supply and drainage field: epoxy resin anti-corrosion steel pipes are also widely used in the field of water supply and drainage, which can effectively protect pipelines from water erosion.
4.Other fields: In addition to the above fields, epoxy resin anti-corrosion steel pipes are also widely used in other fields, such as construction engineering, shipbuilding, agricultural irrigation and other fields.
4. Precautions.
1.During use, sharp objects should be avoided from scratching the surface of the steel pipe, so as not to damage the anti-corrosion layer.
2.During the installation process, it is necessary to avoid excessive bending or twisting of the steel pipe, so as not to cause the anti-corrosion layer to fall off or crack.
3.In the process of use, the pipeline should be inspected and maintained regularly, and possible problems should be found and dealt with in a timely manner.
4.In the process of use, it is necessary to avoid the influence of high or low temperature environment on the steel pipe, so as not to affect its service life and safety.
5.In the process of use, it is necessary to follow the relevant regulations and standards to ensure its safe and reliable use.
In a word, epoxy resin anti-corrosion steel pipe, as a new type of anti-corrosion material, has excellent anti-corrosion performance and durability, and is widely used in various fields. In the process of use, it is necessary to follow the relevant regulations and standards to ensure its safe and reliable use.
