Our factory has a large number of pipes all year round, and we welcome negotiations. Many people only know one thing about the uses of 3pe anti-corrosion steel pipes, but they do not know the other. Its function is really wide coverage, and it is suitable for underground water supply and drainage, underground spraying, positive and negative pressure ventilation, gas drainage, fire sprinkler and other pipe networks in coal mines. Thermal power plant process water waste residue and return water transportation pipeline. The water supply pipeline for anti spray and sprinkler systems has the applicability of Ruisheng. Cable protection sleeves for power, communication, highways, etc. Suitable for high-rise building water supply, heating network, water supply engineering, gas transmission, buried water transmission and other pipelines. Process pipelines for transporting corrosive media in industries such as petroleum transportation pipelines and printing and dyeing. Anti corrosion engineering for sewage treatment discharge pipes, sewage pipes, and biological tanks. For agricultural irrigation pipes, deep well pipes, drainage pipes and other network applications, it can be said that 3pe anti-corrosion steel pipes are essential in current construction, and we believe that with the extension of technology, they will have even more brilliant achievements in the future.

　　We will give a brief explanation of the quality methods for 3PE anti-corrosion steel pipes. This time, we will divide the explanation into two parts. Firstly, as we all know, there are many factors that affect the performance of the 3PE anti-corrosion steel pipe coating, such as the layout of each process, equipment selection, surface quality and heating method, coating temperature, cooling method, transmission accuracy, material characteristics, and testing. Poor control can lead to defects such as weak adhesion, thinness, cracking, or bubbles in the coating. Strictly following standardized and scientific operating methods is crucial for controlling defects and ensuring the yield of anti-corrosion pipes. Let's take a look at the quality related methods for 3PE anti-corrosion in China. Among them, a steel pipe external annular cooling device has been announced domestically, which has improved the cooling effect. However, it still cannot fundamentally overcome the quality defects and thinning of weld bead coating caused by external cooling methods. The ideal method for reducing coating thickness and thinning is to cool from the inside of the steel pipe. The anti-corrosion coating of the brushing type should be applied layer by layer according to the rules, and the coating thickness should be uniform, without any defects such as flow, wrinkles, pinholes, hollowing, etc. Maintenance methods can only be adopted after it is practical; When constructing the anti-corrosion layer of tape type, the construction temperature should be strictly controlled and overheating is prohibited. The composition of steel is uniform, the tonnage of the cold cutting machine is high, and the cutting end face is smooth and neat. However, due to poor material quality, fake and inferior materials often have meat peeling on the cutting end face, which is uneven and lacks metallic luster. A good anti-seepage coating has a good ability to prevent the penetration and corrosion of pipeline surfaces when in contact with highly permeable liquid or gas media; (High mechanical function. The general requirements for welding technology are that the welding rod should be selected well and baked and dried according to regulations. The welding rod used by the welder should be qualified, and the two sides of the weld should be aligned. Before welding, oil, water, rust, and debris should be removed and cleaned. What is the opinion of most people on the storage method of anti-corrosion steel pipes? Do you think it is a very simple and unimportant job? In fact, there are standards for the storage of anti-corrosion steel pipes. The three-layer structure protective layer of polyethylene, also known as three-layer PE (3PE), is an advanced anti-corrosion technology introduced from abroad in recent years.).

　　In the installation and repair of 3pe anti-corrosion steel pipes, it is often necessary to cut the pipes according to the required size. The installation method of the pipeline is determined by the size of the pipe diameter. Large pipes are mostly installed on pipe piers, while small pipes are mostly installed on pipe racks. We will give a brief explanation of the quality methods for 3PE anti-corrosion steel pipes. This time, we will divide the explanation into two parts. Firstly, as we all know, there are many factors that affect the performance of the 3PE anti-corrosion steel pipe coating, such as the layout of each process, equipment selection, surface quality and heating method, coating temperature, cooling method, transmission accuracy, material characteristics, and testing.

　　Before performing anti-corrosion treatment on the 3PE anti-corrosion steel pipe base material, it is necessary to inspect and record the steel pipes entering the inlet platform, perform shot blasting and rust removal on the outer surface of the steel pipes, and then check whether the cleanliness and anchor depth of the outer surface of the steel pipes meet the requirements. If they do not meet the requirements, they should be polished and repaired with a hand grinding wheel. The pipe end should be wrapped with adhesive tape, treated with fine dust, heated to the required temperature at medium frequency, sprayed with epoxy powder, wrapped on the side of the adhesive extruder, and burned on the side of the PE extruder. The anti-corrosion pipes should be water-cooled, and qualified products should be marked by spraying. The pipes should be placed on the platform and stacked for shipment. 3PE anti-corrosion steel pipe with three-layer PE anti-corrosion structure: one layer of epoxy powder (FBE>100um), the second layer of adhesive (AD) 170-250um, and the third layer of polyethylene (PE) 2.5-3.7mm. The three materials are integrated and firmly bonded with the steel pipe to form an excellent anti-corrosion layer. The pipe diameter range is between Φ 60 and Φ 1420, and the wall thickness range is between 2.5-18mm. This is a good anti-corrosion method that can generally increase the service life by 50 years. It not only extends the replacement cycle of underground pipeline equipment, but also greatly saves costs, providing a strong role in construction!
