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 -
