Geometric Properties of Sections of Large Diameter Steel Pipes
(1) Its node connection is suitable for direct welding, which does not need to pass through the gusset plate or other connectors, which saves labor and materials. (2) When necessary, concrete can also be poured into the tube to form a composite member. (3) The geometric charac...Read more -
How to judge the quality of spiral steel pipes
1. From the surface of the spiral steel pipe to see whether the production process of the spiral steel pipe is exquisite. Generally, research and analysis of spiral steel are required, and the section of fake and inferior spiral steel pipes is oval. The reason is that the manu...Read more -
The difference between hot-rolled seamless steel pipe and cold-rolled seamless steel pipe
In terms of processing technology: hot rolling is hot processing, and cold drawing is cold processing. Hot rolling is rolling above the recrystallization temperature, and cold rolling is rolling below the recrystallization temperature; Distinguish from the appearance: the surf...Read more -
Execution standard of spiral welded steel pipes
Spiral seam submerged arc welded steel pipe SY5036-83 for pressurized fluid transportation is mainly used for oil and natural gas pipelines; spiral seam high frequency welded steel pipe SY5038-83 for pressurized fluid transportation is welded by high-frequency lap welding. Spi...Read more -
Why non-metallic pipes or stainless steel pipes cannot be used as long-distance pipelines
The transportation of oil and gas through pipelines requires a certain pressure. The longer the pipeline, the higher the pressure required for oil and gas transportation. The pressure of long-distance pipelines is generally between a few MPa and more than ten MPa. Therefore, t...Read more -
Why 3pe anti-corrosion steel pipe can be anti-corrosion
3pe anti-corrosion steel pipe means three-layer anti-corrosion PE steel pipe. 3pe anti-corrosion steel pipeline is widely used nowadays, and it is a kind of steel pipeline with better anti-corrosion performance. What anti-corrosion materials are the structure of the 3pe anti-c...Read more -
Significance of oil casing heat treatment process
In addition to being used for oil extraction, the emergence of oil casing can also be used as a pipeline for transporting raw materials. In order to enhance the quality of oil casing, every link in the production process is particularly important, especially the temperature co...Read more -
Internal anti-corrosion treatment method of large-diameter spiral steel pipes
The construction of cement mortar fabric should usually be carried out after the spiral steel pipe is laid, the pressure test is qualified, and the soil is compacted according to the design requirements. Due to the small rigidity of the steel pipe and the thin wall, the pipeli...Read more -
The difference between 316L stainless steel pipe and 316 stainless steel pipe
316L stainless steel pipe is a pipe widely used in construction projects. The shape of the tube is an oblong hollow steel tube. Mechanical equipment, petrochemical equipment, medical equipment, food, and light industry pipelines or mechanical parts will all use 316L stainless ...Read more
