Seamless Steel Pipe

 What are the characteristics of large diameter industrial steel pipes? 1. Distinction between Seamless and Welded Large-Diameter Steel Pipes: Large-diameter steel pipes are formed by extruding seamless round tubes. 2. Impact Toughness of Large-Diameter Galvanized Square Steel Pipes: A load acting on a machine part at a very high speed is called an impact load. The ability of a metal to resist failure under an impact load is called impact toughness. 3. Strength of Large-Diameter Steel Pipes: Strength refers to the property of a metallic material to resist failure (excessive plastic deformation or fracture) under static load. Since loads can be applied in the form of tension, compression, bending, and shear, strength is also divided into tensile strength, compressive strength, bending strength, and shear strength. There are often corresponding relationships between various strengths, but tensile strength is generally used as the more basic strength indicator. 4. Pla...

 Cement mortar coating should generally be applied after the spiral steel pipe has been laid, pressure tested, and backfilled and compacted according to design requirements. This is because spiral steel pipes have low rigidity and thin walls, and the pipeline must be in a stable state during coating application. If the coating is applied before the pipe is laid, significant deformation during lifting, transportation, and backfilling can damage the anti-corrosion layer. Before coating application, the inner wall of the spiral steel pipe must be cleaned to remove loose rust, dirt, scale, grease, welding slag, and other adhering substances. The protrusion of the inner wall of the spiral steel pipe should not exceed 1/3 of the designed thickness of the anti-corrosion layer; the vertical deformation of the pipeline should not exceed the design specifications and should not exceed 2% of the inner diameter of the spiral steel pipe. The cement mortar internal anti-corrosion...

 Spiral steel pipes are usually connected by welding, because welded steel pipes are relatively cheaper.However, some projects, due to limitations such as construction period, conditions, and geographical environment, may use other connection methods such as threaded connections, flange connections, socket connections, and grooved connections. Below, we will discuss the characteristics of other connection methods for spiral steel pipes: 1. Flange Connections for Spiral Steel Pipes: Flange connections are generally fast, convenient to install, and require simple tools. However, they do not meet the safety and sealing requirements of most projects. This connection method is suitable for low-pressure steel pipes and frequently moved steel pipes, such as sludge discharge pipes. 2. Grooved Connections for Spiral Steel Pipes: Clamp connection technology has become the preferred technology for connecting liquid and gas steel pipes. Although this technology was developed l...

 Stainless steel grooved pipe fittings are among the most common types of stainless steel pipe fittings. Because we rarely encounter them in daily life, many people are not very familiar with them. So, what are the advantages of stainless steel grooved pipe fittings? The following are advantages of stainless steel grooved pipe fittings: 1. Quick Installation: Using grooved clamp connections and corresponding pipe fittings for pipeline installation eliminates the need for welding, secondary galvanizing, and secondary installation during construction. This greatly improves installation speed. 2. Lightweight Installation: The clamp connections are lightweight, require fewer bolts, and are easy to install, without the need for special technical design. 3. Reliable Installation: A scientifically designed mechanical system and a unique C-shaped rubber sealing ring achieve triple sealing, ensuring the reliability of the stainless steel pipe fitting connection. 4. Cost-ef...

 This time we are going to talk about a newly met European customer. The customer is a local European trader who has never had import experience. In August 2021, Xinyue received an enquiry from this customer for the first time. The content of the enquiry was EN10216-1 seamless carbon steel pipes. There were a total of more than 30 different specifications with thin wall thickness and a gross tonnage of 700. Ton. However, due to the instability of steel prices, customers have been on the sidelines. Xinyue has always maintained close contact with customers, constantly updated prices for customers, and wanted to obtain the best time for customers to purchase. At the same time, considering that the customer is importing for the first time, he will also have doubts about the quality. While constantly updating the price, the Xinyue technical team also prepared complete technical information for the customer, and actively submitted technical documents such as ITP, MPS, Sample MTC, etc. . ...
