3PE anti-corrosion spiral steel pipe and spiral pipe manufacturer for gas transmission

Description :

　　The anti-corrosion coating of 3PE anti-corrosion steel pipes is crucial for the service life of buried pipelines. For pipelines of the same material, some may not corrode after being buried underground for decades, while others may leak within a few years. It's because they use different external anti-corrosion coatings. 3PE anti-corrosion steel pipes have convenient connection and various methods during the construction process. The pipeline itself has the characteristics of light body, easy transfer, easy welding, and few welding joints. When the pipeline is long, PE pipe trenches can be laid using coiled pipes, and when construction conditions are limited, electric fusion welding can also be used. The PE pipe itself uses fusion splicing to connect and package the interface materials, completing the integration of the joint and the pipe with good sealing performance Compared with the pipe body, its interface has higher tensile strength and * * * strength, which can effectively resist the circumferential stress and axial stress caused by internal pressure. Therefore, there is no risk of leakage caused by joint distortion in PE pipes, and the sealing function is appropriately excellent.

Our factory produces seamless steel pipes, straight seam steel pipes, and spiral steel pipes, which are processed into three-layer PE anti-corrosion seamless steel pipes, three-layer PE anti-corrosion straight seam steel pipes, three-layer PE anti-corrosion spiral steel pipes, and three-layer PE anti-corrosion steel pipes for gas pipelines. 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.

　　Before conducting anti-corrosion treatment on the 3PE anti-corrosion steel pipe base material, it is necessary to inspect and record the steel pipe entering the pipe platform. The outer surface of the steel pipe should be shot blasted for rust removal, and then the cleanliness and anchor depth of the outer surface of the steel pipe should be checked for compliance. If it does not meet the requirements, it 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 pipe should be water-cooled, and qualified products should be marked by spraying. The pipe should be placed on the pipe 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! 3PE anti-corrosion is a commonly used anti-corrosion method, in addition to 2PE, 2PP, 3PP. Their manufacturing processes are similar, but the raw materials are not the same. The characteristics of this anti-corrosion method are simple manufacturing process, good anti-corrosion effect, and low price. It is widely recognized as an anti-corrosion method in the pipeline manufacturing industry! In addition, our company has strong production equipment and can independently undertake anti-corrosion and insulation projects. We welcome new and old customers to call us for consultation!
