Foreign anti-corrosion coating technology

Epoxy resin composite coating

Epoxy composite coating system is suitable for protecting pipelines from abrasion, harsh environmental conditions and external corrosion. The advanced anticorrosive coatings are American Amo 370 pipe coating (AP370PLC). It is a long-term corrosion barrier for transitions from land to air, forming a chemical barrier that blocks most chemicals, including caustic soda, dilute acids, salt solutions, water, steam and petroleum solvents. . It is a wet-laid product that can be used for both straight and bent tubes, T-tubes and other shapes. Due to its durability, the system greatly reduces regular maintenance. These materials have the following characteristics: mixing ratio of 1:1 (equal mixing); color: Part A is white, Part B is black, mixed & cured to light gray; AP370PLC kit provides 1 quart, 1/2 Gallon and 1 gallon drum with 1 roll of fiberglass tape (Note: 1 gallon kit can cover approximately 25 square feet of pipe surface); continuous operating temperature: -51 ° C to 91 ° C; use time / working time: 24 °C, about 45 minutes; curing time: 29 ° C, about 2 hours; provide UV protection; epoxy 370A & B storage period is 2 years

Ceramic filler coating

It is applied to brushed ceramic filling coating system and is designed for steel, concrete and so on. In chemical and related industries, it can be used to protect surfaces from exposure to strong chemicals. It is designed as a non-structural pipe coating that is more durable than traditional tape coatings, paints and waxes. The system is primarily used to prevent circumferential welds, land contact surfaces, external corrosion of exposed ground lines, and topcoats for Amo pipe cover. The AP385PMC can be applied to vertical, elevated and horizontal surfaces to a thickness of 30-40 mils (762-1016 microns). The installation procedure is: Complete surface pretreatment. Mix A and B. Brush the mixed AP385PMC onto the treated surface with a suitable hard brush. After a short curing, it will become flat and smooth. It is generally not necessary to perform two coats because the thickness of the first pass of the coating is usually sufficient. If a second coat is required, it must be applied after the first coat has gelled (stable, but still tacky when touched). Cured.

Phenolic epoxy coating

Fast curing phenolic epoxy coating, 100% solids, completely harmless. Among them, the US Novick R200 is excellent in this field, and it can be used as a coating for pipeline repair. The maximum operating temperature of these pipes is up to 200 °C. This two-component, solvent-free epoxy coating easily achieves a dry film thickness of 40 mils (1 mm). This product provides better adhesion and abrasion resistance. Applications: Annular welds, valves, fittings, curved and irregular shape repair pipes, new pipes or other metal substrates that require corrosion protection. Material characteristics and advantages: 100% solid content, novolac epoxy resin; no volatile organic compounds, no isocyanate; phenolic chemistry - for pipelines, operating temperature up to 200 ° C; higher wear resistance; Novi The gram-R200 can be sprayed or hand-operated; it has better adhesion on bare steel and epoxy powders; excellent cathodic disbondment, adhesion and elasticity. Recommended thickness: wet film: up to 40 mils/layer dry film: up to 40 mils/layer

Polymer composite

Specialized protection system applications, the representative material in this field is EE-11 produced by American company Ake, which has underground pipe coating for all segments, sprayable phenolic ceramic filler coating, suitable for eroding water environment. The immersion effect is good when the temperature is raised to 300F. Resist strong wear and tear. High flexibility allows the EE-11 to be used in tube sheets and underground pipes. The EE-11 primer containing zinc phosphate reduces corrosive undercutting. Whether fresh water, salt water or salty, pipe/tube seams are a key point of erosion, corrosion & leakage, depending on whether the unit will be degraded. The Aker pipe coating is accompanied by a 10-30 cm DT coating that effectively seals areas and improves future corrosion and corrosion. The use of a more flexible EE-11 system helps prevent cracks, cracks and leaks caused by bending and thermal stress. For underground pipelines, EE-11.5 has good adhesion, no dents or sags, 5-10 mil DFT.
