2.Materails: 20#, Q345B, GR.B, X42, X56, P11, P22, ST37, ST45.8, ST52, S235JR, S355JR, STP430
10. Straight seam steel processing methods:
1). Forged Steel: the use of a reciprocating hammer impact force or pressure to press the blank change to our desired shap and size of a pressure- processing methods.
2). Squeeze: It is placed in a sealed steel metal squeeze Jane, put pressure on one end of the metal from the provisions of the extrusion die orifice obtained had the same shape and size of the finished product processing methods, used for the production of non-ferrous metal sheet steel.
3). Rolling: The steels metal blank by a pair of gap (shapes) of rotation of the roll, the roll due to the compression of the material cross-section is reduced, increasing the length of the press working method.
4). Pullout steel: is already rolled metal blanks (type, pipe, products, etc.) through the die orifice pull aside to increase the length of the cross section reduction processing methods are mostly used as a cold.
11. 2PE / 3PE preservative and single PE anti-corrosion
1). 3PE corrosion: three PE pipe anti-corrosion structure: the first layer of epoxy powder (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 Φ60～Φ1420
The same story PE pipe corrosion structure, the first layer of adhesive (AD), a second layer of polyethylene (PE), two kinds of integrated material, the thickness of layers with three PE Standard: 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), after heating the steel pipe IF rotate top steel container filled with polyethylene powder is formed by leaching polyethylene coating pipe outer wall surface dusted.
4).Compared with foreign 3PE anticorrosive, single PE anti-corrosion propertie
| 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 adhensive, outer-storey-density polyethylene | Single layer polyethylene, low density polyethylene |
| Coating thickness | 2.5-4mm | 1-1.5mm |
| Adhesion | Strong | Generally, intolerance boiled |
| Performance | Corrosion resistance, wear resistance | Impact general, intolerance scratches |
| Defect | No | Easy to pinholes, leveling uneven apperance |
12. Coal tar epoxy
The product is formulated with an epoxy resin, coal tar pitch, anti-rust pigments, additives, modified amine. Products with rapid drying, good adhesion, flexibility, and easy two-component packaging and construction. With acid, alkali, salt, water, oil etc .
① The 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.
② suitable 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》
① improve the life of the steel pipe;
② combination of mechanical strength and plastic pipe corrosion resistance in one;
③ outer coating of 2.5mm or more, scratch resistance, bump;
④ inner wall of the friction coefficient is small, 0.0081-0.091, reduce energy consumption; ⑤ the inner wall to achieve national health standards;
⑥ smooth wall is not easy scaling, self-cleaning function.
