PN8710 anti-corrosion
When there are many types of corrosive media in steel pipes, such as acids, alkalis, salts, oxidants and water vapor, the coating must be chemically inert and resistant to acid, alkali and salt corrosion. The coating film should have a dense structure, good waterproof permeability and strong adhesion. , tough and plump. In this case, IPN8710 anti-corrosion is suitable.
IPN8710 anti-corrosion primer: It is composed of polyurethane polyethylene, modified epoxy resin, non-toxic anti-rust pigments, fillers, additives, etc. It solidifies at room temperature to form an interpenetrating network. The coating film structure is dense, acid, alkali, salt, and rust-proof. It has excellent performance and strong adhesion, and is used for anti-corrosion primer coating on the inner wall of water supply pipelines.
IPN8710 anti-corrosion topcoat: composed of epoxy, rubber resin modification, non-toxic anti-rust pigments, fillers, additives, etc. Excellent chemical resistance, non-toxic, anti-microbial erosion, used as anti-corrosion topcoat for the inner wall of water supply pipelines.
FBE epoxy powder anti-corrosion
FBE epoxy powder anti-corrosion structure: The electrostatic spraying process is used to coat epoxy powder on the surface of the steel pipe to form a film in one go. The coating has the advantages of simple coating operation, no pollution, good impact resistance and bending resistance, and high temperature resistance.
2PE/3PE anti-corrosion
2PE/3PE anti-corrosion structure: epoxy powder is electrostatically sprayed on the surface of the steel pipe and laterally wound with adhesive and laterally wound with a polyethylene anti-corrosion layer. Combining the excellent properties of the three, it significantly improves the overall quality of the anti-corrosion pipeline. It has chemical corrosion resistance, cathodic stripping resistance and mechanical damage resistance.
Epoxy coal pitch anti-corrosion
Epoxy coal tar pitch anti-corrosion structure: The anti-corrosion coating made of epoxy resin + coal tar pitch + filler is applied on the surface of the steel pipe with glass cloth as a reinforced coating to form an anti-corrosion layer, which is often used for anti-corrosion on the outer wall of the pipeline. The thickness is generally 0.5~1.0mm.
High-density polyethylene jacket anti-corrosion
High-density polyethylene jacket anti-corrosion structure: The outer surface of the steel pipe is wrapped with high-density polyethylene material, which has extremely high mechanical strength and excellent corrosion resistance. It can protect the steel pipe from being damaged by external factors during transportation, installation and use. the damage caused. Antioxidants, UV stabilizers and carbon black should be added to the outer casing. The polyethylene outer casing is easy to age. If it is stored in the open air, it should be covered with a tarpaulin. The stacking place should be away from high heat and fire sources. After being made into anti-corrosion steel pipes, it is prohibited to be exposed to the sun or quenched. Otherwise, the polyethylene outer casing will easily crack and affect the product. performance and longevity.
Silicone high temperature anti-corrosion
Silicone anti-corrosion layer, hard silicon calcium tile insulation layer, galvanized iron wire reinforcement layer, aluminum silicate fiber cloth waterproof layer, steel casing, and the organic silicon coating of titanium-aluminum alloy powder on the inner surface of the steel casing and the organic silicone coating on the outer surface Made of silicone coating. The silicone anti-corrosion layer is composed of a coating cured product composed of silicone resin, ceramic powder, talc powder, mica powder, alumina powder and titanate. It has anti-corrosion, heat preservation, waterproof and external protection properties. Its silicone anti-corrosion layer can withstand high temperatures of 600°C and can be used for insulated pipelines transporting high-temperature media of 550°C.
Classification of stainless steel pipes1. Classification by production method:
(1) Seamless tubes - cold drawn tubes, extruded tubes, cold rolled tubes.
(2) Welded pipe:
(a) Classification by process - gas shielded welded pipe, arc welded pipe, resistance welded pipe (high frequency, low frequency).
(b) According to welding seam - straight seam welded pipe, spiral welded pipe.
2. Classification according to cross-sectional shape: (1) circular steel pipe; (2) rectangular pipe.
Spiral steel pipe stacking requirements1. The principle requirement for stacking spiral steel pipes is to stack them according to types and specifications on the premise of ensuring stable stacking and ensuring safety. Different types of materials should be stacked separately to prevent confusion and mutual erosion;
Difference Between Straight Seam Steel Pipe and Spiral Steel Pipe
Advantages of Using Carbon Steel in ConstructionSteel is an alloy metal, which means it’s a combination of several types of elements. In the case of steel, this is a combination of iron, carbon, and trace elements. It has a number of advantages for construction applications due to the fact that it’s fairly inexpensive to manufacture and has a very high tensile strength.
What determines the type of steel is the ratio of elements used to produce it, and it’s the magic formula of the carbon steel alloy created that makes it preferred for many projects. While there are thousands of different types of steel, these types are generally bucketed into four categories: carbon steel, alloy steel, stainless steel, and tool steel.
Global crude steel production fell 4.3% year-on-year in MarchOn April 23, the World Steel Association (WSA) released global crude steel production data for March. In March, crude steel output in the world's 71 countries and regions included in the statistics was 161.2 million tons, a year-on-year decrease of 4.3%. In the first quarter of this year, crude steel output in the world's 71 countries and regions included in the statistics was 469 million tons, a year-on-year increase of 0.5%.
