The length of steel pipes used for pipelines, but for the convenience of users, when the steel pipes sold at any time are reserved for production, the Q235A spiral steel pipes are produced within the specified length of the steel pipes, but when the actual order is made, the steel pipes of standard

Improper heat treatment of seamless steel pipes is likely to cause a series of production problems, resulting in greatly reduced product quality and turning into waste products. Avoiding mistakes that are easy to make during heat treatment is saving money. What problems should we pay attention to an

To solve the problem of excessive misalignment in the alignment of spiral steel pipe nozzles, the following preventive measures should be taken in quality management control:1. Try to use the internal alignment device.2. Do a good job in engineering measurement and trimming when assembling.3. When t

Product: Seamless steel elbowStandard: SMLS A234 WPB ASME B16.9 NaceProject Location: SingaporeApplication: industrial energy transportation projectSize: 4'' 90DEG SCH40 LR BWWith long-time business discussion, to show Singapore's new project steel elbow for you. These steel elbows will be used in t

It is inevitable to weld and cut the spiral steel pipe structure in the application of spiral steel pipe. Due to the characteristics of the spiral steel pipe itself, compared with ordinary carbon steel, the welding and cutting of the spiral steel pipe have their particularity, and it is easier to pr

(1) During the extrusion process, the temperature of the inner lining of the spiral steel pipe increases continuously with the extrusion process. At the end of the extrusion, the temperature of the inner wall of the inner lining near the extrusion die is higher, reaching 631 °C. The temperature of t

Large-diameter straight seam submerged arc steel pipes are mainly responsible for the pipeline transportation of marine and land oil and gas, oil and natural gas, coal, and ore pulp.The methods and characteristics of international pipe-making technology, the forming methods of large-diameter longitu

Product: TP316L steel pipeStandard: ASTM A312Size: 609.6MM*6.35MM*6000MMApplication: Industrial water supply projectProject Location: ThailandBecause of the TP316L steel pipe's long lifetime, the manufacturing processes take each test to ensure the steel pipe quality. These steel pipes are with the

1. Impact toughness of large-diameter steel pipe: The load acting on the machine part at a high speed is called impact load, and the ability of the metal to resist damage under the action of impact load is called impact toughness.2. Strength of large-diameter steel pipe: Strength refers to the perfo

Thick-walled steel pipes have a wide variety of steel types and specifications, and their performance requirements are also various. All of these should be differentiated as user requirements or working conditions change. Generally, steel pipe products are classified according to cross-sectional sha
