The main reported shortcomings include dew point peeling, cathode peeling, cathodic protection shielding peeling, corrosion under the film, etc. Most of the reports on the defects are still in the stage of theoretical speculation. For example, the problem of cathodic protection shielding is mentioned in the data. So far, there is no actual practice on the anticorrosive layer. Instances of cathodic protection shielding occurring during operation have been reported. Epoxy coal pitch anti-corrosion spiral steel pipe is what we often call several cloths and several oils. The common ones are one cloth, two oils, three cloths, two oils, five steps, three oils, seven cloths and four oils. The components of epoxy coal pitch anti-corrosion spiral steel pipe are epoxy coal pitch primer and topcoat, both of which use epoxy resin and coal pitch as the main film-forming materials, adding various anti-rust pigments, insulating fillers, tougheners, leveling agents and diluents. Anti-settling agent, etc. Appearance primer component A, iron red, component B, black topcoat are all black. It has excellent corrosion resistance to chemical media and good physical and mechanical properties. It has good adhesion. The coating film is tough and has excellent electrical insulation and anti-permeability. It is resistant to stray current and anti-microbial erosion. After the film is formed, the number of construction passes can be reduced.
Inspection of the anti-corrosion layer of epoxy coal pitch anti-corrosion spiral steel pipe
⑴ Surface dryness and solidification of the anti-corrosion layer .
⑵ Appearance inspection: The coating appearance is smooth and flat, the color is uniform, and there are no bubbles, sagging, cracking or peeling. Coated pipes should be inspected one by one.
⑶ Thickness inspection: The thickness specified by the anti-corrosion layer grade is used as the standard for testing with an anti-corrosion layer thickness gauge. Each pipe is randomly inspected and each section is measured at a certain distance apart. Each section is measured at the upper, lower, left and right points. If the thinnest point is lower than the specified thickness, it will be deemed unqualified. If the roots are still unqualified during random inspection, all of them will be considered unqualified. Anti-corrosion pipes with unqualified thickness should be repaired to qualified before the coating is cured.
⑷ Leak point inspection of epoxy coal pitch anti-corrosion steel pipes. The anti-corrosion pipes in designated sections should be inspected for leaks in standard sections.
⑸ Inspection of adhesion of epoxy coal pitch anti-corrosion steel pipe. After the anti-corrosion layer is cured, inspect according to Article .. Spot check each measuring point of each pipe. If they are unqualified, they will be randomly inspected and all of them will be considered unqualified.
① During and after surface coating construction, the painted workpieces should be protected from flying dust and other debris. ② The inspection after painting should ensure that the coating is consistent in color, bright and bright, and free of defects such as wrinkles, bubbling, sags, or leaks. Order Fuzhou Epoxy Coal Asphalt Anticorrosive Steel Pipe Hotline ③ Determination of coating film thickness Use a contact-type paint film thickness gauge to measure the paint film thickness. The paint film thickness gauge generally takes the average value of the thickness at the measurement points.
Epoxy coal pitch anti-corrosion coating is composed of two main components: epoxy and coal pitch. It is a two-component paint (epoxy) and B (curing agent). It has excellent adhesion, toughness, moisture resistance, water resistance, and chemical media resistance. It has the ability to prevent various ions from penetrating the paint film and has the characteristics of expanding and contracting at the same time as the object being painted. The paint film never peels or cracks. Thickness.~.. Epoxy coal pitch is a cost-effective form of anti-corrosion. Engineering measurements show that epoxy coal pitch plus cathodic protection is used. There has been no corrosion in oil and gas pipelines for twenty years. According to analysis, steel traders in the domestic construction steel market have begun to return to the market for business after the holiday, but downstream procurement has not yet fully entered the market. Demand recovery is very slow and the overall market transactions are sluggish. People in the market say that the supply environment has recovered relatively quickly and is now basically in a normal state, but sales have been slow to pick up, which has put pressure on the market. The sharp decline in the futures market suddenly became the trigger for a comprehensive decline in the current market. At present, the application effect of anti-corrosion layer at home and abroad is very good, and there are few reports on the defects caused by its use.
