Introduction to straight seam steel pipes and precautions for using straight seam steel pipes
Straight seam steel pipes do not refer to a certain type of steel pipe, but a large category of welded pipes. They are made of steel strips. Steel pipes made using straight seam high-frequency welding equipment can be called straight seam steel pipes. In fact, to put it simply, when welding steel...Read more -
The significance of the heat treatment process of oil casing
In addition to being used for oil extraction, 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 control during the period, which must b...Read more -
Submerged arc steel pipe welding control measures and forming methods
Submerged arc steel pipe welding control measures: Submerged arc steel pipe has become the steel pipe for large oil and gas transportation projects at home and abroad with its large wall thickness, good material, and stable processing technology. In the large-diameter submerged arc steel pipe wel...Read more -
Factors affecting the accuracy and resolution of the oil casing wall thickness detection
API standards stipulate that the inner and outer surfaces of import and export oil casings shall not have folds, separations, cracks, or scars. These defects should be thoroughly removed, and the removal depth should not be less than 12.5% of the nominal wall thickness. Oil casing must be fully...Read more -
What details should thick-walled steel pipes go through before use
The selection of welding methods for thick-walled steel pipes should be based on the material and wall thickness of the thick-walled steel pipes. Because different welding methods have different arc heat and arc force, different welding methods have different characteristics. For example: Tungste...Read more -
Inspection methods for large-diameter straight seam welded pipes commonly used in industrial projects
There are many methods for quality inspection of large-diameter straight seam welded pipes, among which physical methods are also commonly used inspection methods. Physical inspection is a method of measuring or inspecting using some physical phenomena. Inspection of internal defects of materials...Read more
