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 -
How to use fire-fighting steel-plastic composite pipe
How to use the steel-plastic composite pipe correctly must be used correctly by the specifications. Large-diameter plastic-coated steel pipe steel-plastic composite pipe is a new type of pipe, which is used in many fields and has many excellent properties, especially its anti-...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 -
What are the methods of steel pipe surface treatment
Long-term exposure to steel and other metal materials in the atmosphere will inevitably corrode and form loose rust, which will cause serious losses to modern industries. At present, pipelines play an important role in various industries, so the surface treatment of steel pipe...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 -
How to improve the wall thickness accuracy of reinforced 3pe anti-corrosion steel pipes
There are many applications of reinforced 3pe anti-corrosion steel pipes. However, due to the low wall thickness accuracy of reinforced 3pe anti-corrosion steel pipes, there is a phenomenon of uneven thickness, which will have a great impact on the performance of reinforced 3p...Read more -
Reasons for uneven anti-corrosion thickness of 3PE anti-corrosion steel pipe
The industry standard SY/T0413-2002 does not stipulate the uniformity of the thickness, it stipulates the minimum thickness value of the coating, but it is required that the minimum thickness value of the coating cannot be lower than the thickness value of the low point, not t...Read more
