Erw Black Steel Pipe - factory customized SHS pipe – Arc Welding Square Steel Pipes – TOP STEEL
Erw Black Steel Pipe - factory customized SHS pipe – Arc Welding Square Steel Pipes – TOP STEEL Detail:
1. square and rectangular tube, a tube called a square and rectangular tubing, which is the side looks like, and unequal steel. After treatment process is rolled strip made. The general is to strip after unpacking, smooth, curl, tube welding form, and then rolled into the square from the round tube and then cut into the required length.
2. the standard: GB square tube, the standard square tube, inch square tubes, American standard tube, square tube European standard, non-standard square tube.
3. the material: carbon steel (Q195, Q215, Q235, SS400,20 # steel, 45 # steel, etc.); low-alloy steel (Q345,16Mn, Q390, ST52-3, etc.).
4. the surface treatment: hot galvanized, electro-galvanized, coated with oil, pickling.
5. Application: Widely used in machinery manufacturing, construction, metallurgical industry, agricultural vehicles, agricultural greenhouses, automotive, railway, highway guardrail, container framework, furniture, decoration as well as steel and other fields.
6.2PE/ 3PE anti-corrosion and single-layer PE anticorrosive
Three-layer structure of PE pipe corrosion: the first layer of powder epoxy (FBE> 100um），the second layer of adhesive ( AD) 170～250um, a third layer of polyethylene (PE) 2.5～3.7mm. Three materials integration, and with the steel firm to form an excellent coating.
Diameter range of Φ60～Φ14202).2PE anti-corrosion steel pipe：
PE pipe corrosive story structure, the first layer of adhesive (AD), a second layer of polyethylene (PE), the same as the standard blend of two materials, the thickness of layers with three PE: SY/ T0413-2002 buried steel pipeline polyethylene coating technology standards GB/ T23257-2009 buried steel pipeline polyethylene coating technology standards
3). Single PE anti-corrosion steel:
single layer PE is the use of anti-corrosion steel curtain coating process ( also known as curtain method), the steel pipe after rotation frequency heating, steel top is fitted with a polyethylene powder container by pouring dusted steel tube surface polyethylene coating.
4). 3PE anticorrosive and external single PE anticorrosive performance comparison
|performance comparison||Outer 3PE FBE epoxy pipe||Outer single polyethylene pipe|
|Sintered outer coating process||Wrapped three-layer structure||Curtain method, curtain coating, single|
|Anti-corrosion structure||The middle layer is adhesive, outer-storey-density polyethylene||Single layer polyethylene, low density polyethylene|
|Adhesion||Strong||Generally, intolerance boiled|
|Performance||Corrosion resistance, wear resistance||Impact general, intolerance scratches|
|Defect||No||Easy to pinholes, leveling uneven apperance|
7. Coal tar epoxy
The product is formulated with an epoxy resin, coal tar pitch, anti-rust pigments, additives, modified amine from. Products with rapid drying, good adhesion, flexibility, and easy two-component packaging and construction. With acid, alkali, salt, water, oil etc.
①The paint combination of high mechanical strength epoxy resin adhesive force, erosion and chemical resistance characteristics of asphalt water-resistant, anti-microbial, anti-plant roots, is a high performance anti-corrosion insulation coating, the products are Good chemical resistance, water resistance.
②suitable for oil, gas and water pipelines, water, gas, pipelines, refineries, chemical plants, sewage treatment plants and pipeline corrosion of equipment, may be used as antiseptic and mining offshore oil rigs and underwater portion of the ship , corrosion downhole equipment.
4). The process has been the duty epoxy powder coating using electrostatic spraying. Since epoxy powder Jin Su troubled by adhesion, epoxy powder dip has not been able to promote. Current come with three coconut epoxy powder dip developed special phosphate solution, for the first time to overcome the adherence problem epoxy powder dip process, began to dip epoxy powder of this emerging technology.
FBE epoxy powder preservative execution SY / T0315-2005 《steel pipeline single FBE topcoat technical specifications》
①improve the life of the steel pipe；
⑤the inner walls meet the national health standards；
