Upset tubing, as the name suggests, is to thicken the tubing to make the tubing more robust and durable. The thickness of a standard pipe is not increased randomly. Increasing randomly may cause cracks or brittle fractures due to changes in the stress structure of the pipe body. Any thickening of the tubing must be thickened after in-depth research and design verification.
The upset tubing was developed under the background of this era. The purpose is to alleviate the oil loss and serious environmental pollution in a timely and effective manner. The laying of upset tubing makes it possible whether you are in the ocean or buried in the ground. Will make upset tubing safer, more reliable, and better. The landing of thicker oil pipes has produced strong social reactions. Oil delivery has been greatly increased, and production capacity has risen rapidly.
Upset tubing classification:
Thickened oil pipelines are divided into marine special pipelines, land special pipelines, and special environment special pipelines. In the vast ocean, marine special pipelines are used for offshore and offshore pipelines to effectively reduce corrosion and increase service life; use special pipelines on land , Can greatly exert the function and role of the oil pipeline. The special tube is used in highly severe environments such as strong acids and alkalis, and has good resistance to these highly corrosive environments and a long-term preventive mechanism.
