Epoxy coal asphalt heavy anti-corrosion steel pipe: an effective pipeline anti-corrosion method.
With the process of industrialization, steel pipes are more and more widely used in various fields, and anti-corrosion treatment is a key technology. Epoxy coal asphalt heavy anti-corrosion steel pipe is an effective pipeline anti-corrosion method, this article will introduce its characteristics, application scope and use method in detail.
1. Characteristics of epoxy coal asphalt heavy anti-corrosion steel pipe.
Epoxy coal asphalt heavy anticorrosive steel pipe is mainly composed of epoxy resin, coal tar asphalt and filler. It has the following features:
Excellent anti-corrosion performance: epoxy coal asphalt heavy anti-corrosion steel pipe can effectively resist the corrosion of various chemicals and has a long service life.
Good adhesion: This anti-corrosion coating can adhere tightly to the surface of the steel pipe and is not easy to fall off.
Weather resistance: Epoxy coal asphalt heavy anti-corrosion steel pipe has good weather resistance and can remain stable even under harsh environmental conditions.
Convenient construction: The construction of epoxy coal asphalt heavy anti-corrosion steel pipe is relatively simple, and the requirements for the environment and equipment are not high.
Second, the application range of epoxy coal asphalt heavy anticorrosive steel pipe.
Due to the above-mentioned excellent performance, epoxy coal asphalt heavy anticorrosive steel pipe is widely used in the following fields:
Oil & Gas: Oil and gas pipelines often need to pass through a variety of complex environments, and epoxy coal pitch heavy anti-corrosion steel pipes can provide effective protection for these pipelines.
Chemical industry: Pipelines in the chemical industry are often exposed to various corrosive chemicals, and epoxy coal asphalt heavy anticorrosive steel pipes can prolong the service life of pipelines.
Urban water supply and drainage: Urban water supply and drainage pipelines need to withstand the corrosion of groundwater, and epoxy coal asphalt heavy anti-corrosion steel pipes can provide reliable protection for these pipelines.
Construction industry: The water supply and drainage pipes of buildings, roof rainwater pipes, etc. need to be treated with anti-corrosion, and epoxy coal asphalt heavy anti-corrosion steel pipes can meet these needs.
3. The use of epoxy coal asphalt heavy anticorrosive steel pipe.
When using epoxy coal pitch heavy anticorrosive steel pipes, the following steps need to be followed:
Surface treatment: clean the surface of the steel pipe to remove impurities such as oil stains and oxide scales to ensure the adhesion between the coating and the substrate.
Primer coating: Epoxy resin and coal tar bitumen are mixed in a certain proportion and then coated on the surface of the steel pipe to form a layer of primer. The function of the primer is to improve the adhesion between the coating and the substrate, and play a certain role in preventing rust.
Topcoat coating: After the primer has dried, one or both coats are applied. The main function of the topcoat is to provide anti-corrosion protection and decorative effect. Depending on the need, different colors and gloss levels can be selected.
Curing: Dry at room temperature for at least 24 hours for the coating to fully cure. The cured coating has good abrasion, impact and chemical resistance.
Quality inspection: Carry out quality inspection on the painted steel pipes, including visual inspection, adhesion test, etc. If necessary, sampling testing can be carried out to ensure that the overall quality meets the requirements.
Installation and use: After confirming the quality of the qualified, the epoxy coal asphalt heavy anti-corrosion steel pipe is installed to the required position, and connected and fixed in accordance with the relevant specifications. Pay attention to the protective coating during installation to avoid scratches or bumps.
Maintenance: In the process of use, the epoxy coal asphalt heavy anticorrosive steel pipe should be regularly inspected and maintained, and the damaged or aging parts should be repaired in time to maintain its good anti-corrosion effect and service life.
