The application field of anticorrosive adhesive tape is expanding

As a professional anticorrosive material, polyethylene anticorrosive adhesive tape is widely used in our country with the development of our economy and the development of some projects. It is mainly used in the transmission of oil and natural gas; the external surface anticorrosion of buried steel pipes such as water supply and drainage and gas transmission in chemical industry and urban construction. It has the characteristics of convenient construction and no pollution. It is one of the first anti-corrosion systems selected for pipeline external anti-corrosion. The rubber layer is butyl rubber, which has excellent aging resistance, sealing and insulation effect. All performance indexes of the products are in full compliance with the standards of PetroChina SY / t0414-2007, ANSI / awwac209-00 and nacemr0274-95 of Art Association, and reach the leading level of similar products at home and abroad.

Features of polyethylene anticorrosive adhesive tape:

1. The thickness of the adhesive layer is uniform, and the adhesive sealing performance is good.

2. The bonding force between the base material and the adhesive layer is large, and there is no degumming in the storage or construction process.

3. Good heat aging resistance and strong UV resistance.

4. High tensile strength, appropriate elongation at break, convenient for mechanization and manual winding.

5. The variety, specification and color are complete, including anti-corrosion belt (inner belt), protection belt (outer belt), joint coating belt, anti-corrosion primer and construction equipment.

Usage of polyethylene anticorrosive adhesive tape:

1. Remove rust, welding slag, burr, oil and sundries on the surface of the pipeline, and keep it clean and dry. Meet the requirements of GB / T 8923, manual derusting shall reach ST3, and mechanical derusting shall reach Sa2.5.

2. The primer shall be applied manually or mechanically to ensure uniformity and no omission.

3. After the primer is dry for 3-5 minutes, the tape can be wrapped. The wrapping of polyethylene adhesive tape shall meet the requirements of the engineering design anti-corrosion coating grade and structure.

4. Select the matching primer P19 produced by our company.

5. Construction temperature: - 5 ℃~ + 50 ℃; it is forbidden to construct in the open air in rainy, snowy and foggy days when the humidity is more than 85% and in windy and sandy environment.

Transportation and storage of polyethylene anticorrosive adhesive tape:

1. It shall be sun proof, rain proof, anti freezing and heat preservation to prevent crushing and deformation.

2. During transportation or storage under - 5 ℃, it needs to be stored at 20 ℃ for 48 hours before use.

3. It shall be stored in a warehouse with a temperature of 5-30 ℃ and a relative humidity of less than 75%, away from heat source and open fire.

4. The shelf life is 12 months.

Polyethylene anti-corrosion adhesive tape has been widely used in oil and gas steel pipeline as external anti-corrosion material since 1960s, and it has a history of more than 40 years.

The excellent anticorrosive performance and convenient construction performance of polyethylene anticorrosive adhesive tape occupy a certain position in the pipeline anticorrosive material system. And because of the continuous improvement and improvement of the domestic production enterprises of polyethylene anticorrosive adhesive tape, the variety and quality of polyethylene adhesive tape can meet the technical requirements of special and enhanced anticorrosion of various buried pipelines, so as to expand the application field of polyethylene anticorrosive adhesive tape.

Polyethylene anticorrosive adhesive tape is composed of inner tape, outer tape and patching tape with polyethylene as base material and butyl rubber as adhesive layer under heat capacity. The inner belt plays an anti-corrosion role and the outer belt plays a protective role. The patching belt is suitable for the pipeline interface. It has good toughness and tensile strength, and has super strong moisture and heat-resistant expansion characteristics.

Suzhou Qianggu pipeline anti-corrosion material Co., Ltd. is located in FENHU Economic Development Zone, Wujiang District, Suzhou City, Jiangsu Province. It is a comprehensive anti-corrosion and water-proof material production industry with complete anti-corrosion products, advanced equipment and stable quality in China.
