,Single layer sintered epoxy powder anti-corrosion steel pipe

Hebei Tianze Pipeline Co., Ltd. sells hot-selling anti-corrosion steel pipes, single-layer sintered epoxy powder anti-corrosion steel pipes, single-layer sintered epoxy powder anti-corrosion steel pipes, B (double-layer sintered epoxy powder anti-corrosion) implementation standards: /, this product application It is widely used in the anti-corrosion of steel structures and mechanical equipment, various storage tanks, transportation pipelines and other steel materials in marine facilities, petrochemical industry, construction industry and other industrial and mining enterprises. Anti-corrosion steel pipes are widely used in pipeline engineering fields such as petroleum, chemical industry, natural gas, heat, sewage treatment, water sources, bridges, and steel structures in my country. The quality is guaranteed, welcome to negotiate. The external anti-corrosion layer of buried long-distance pipelines is no longer dominated by petroleum asphalt. Now there are two layers, coal tar enamel paint, fused epoxy powder (B), three layers and other coatings. Used in different projects.
Coal tar enamel: Coal tar enamel was once the most widely used coating in advanced Western countries. It has good anti-corrosion properties, good bacteria resistance, soil root thorn resistance, and long service life. It has a series of advantages, but has poor mechanical properties, flowing at high temperatures and brittle at low temperatures. It is easy to cause damage during transportation and construction. In actual operation, due to heavy damage, the cathodic protection current density is relatively high. .
, B sintered epoxy powder has a wide operating temperature range, good soil stress resistance, chemical media immersion resistance, high hardness, small friction coefficient, and does not produce cathodic protection shielding. It is an excellent performance External anti-corrosion coating, but there are still some unsatisfactory aspects. The single layer B is thin and brittle, and has little impact resistance. Another disadvantage of B is its high water absorption rate.
The two layers have a series of advantages such as good impact resistance, low water vapor permeability, good resistance to immersion in chemical media, long service life, and easy repair
. Due to their high mechanical strength and ease of repair, they are practical in operation. The probability of pipeline damage is less than other types of coatings, so it has the advantages of small cathodic protection current density, large cathodic protection station spacing, and extremely low cathodic protection operating costs. The biggest disadvantage of the two layers is that the bonding performance between the adhesive and the pipe is far inferior to that of the epoxy resin. Once the adhesive is lost, the steel pipe under the peeled coating will not receive sufficient cathodic protection, resulting in cathodic protection shielding.
The first layer of three layers is epoxy coating, the second layer is adhesive, and the third layer is extruded polyethylene outer protective layer.
The layers are closely bonded to each other to form a composite Structure, learn from each other’s strengths. It utilizes the strong
bonding force between epoxy powder and the surface of the steel pipe to improve adhesion and utilizes the excellent mechanical strength, chemical stability, insulation and resistance to plant roots
penetration of extruded polyethylene. properties, water penetration resistance, etc. to improve its overall performance, making the overall performance of the three-layer anti-corrosion coating more outstanding and comprehensive. Three-layer polyethylene/double-layer polyethylene anti-corrosion seamless pipe, spiral pipe, straight seam pipe
Steel pipe diameter: mmm three-layer polyethylene anti-corrosion seamless steel pipe Cangzhou Tianze Pipeline Co., Ltd. specializes in the production, processing and sales of anti-corrosion pipes , Anti-corrosion steel pipe refers to a layer-structured polyolefin coating (M) external anti-corrosion steel pipe, which is a commonly used anti-corrosion pipe in China. Others include B epoxy powder, epoxy coal pitch and other anti-corrosion products.
