The spiral steel pipe is a steel pipe made of steel plate rolling, and its surface is spiral. It has high pressure resistance, corrosion resistance, and strength, and is widely used in the fields of oil, chemical industry, natural gas, architecture and other fields.
The spiral steel pipe is restricted by many conditions during the production process of spiral steel pipes. If the current is large, the phenomenon of welding penetration will occur. If the current is smaller, the phenomenon of insufficient welding will occur. And the spiral steel pipe pays more attention to the procurement because of the thick wall thickness.
1. Check whether the appearance of the spiral steel pipe is wrong.
2. Check whether the welding of the spiral steel pipe is missing or trachoma.
3. Whether there is a supporting support in the mouth of the two ends of the spiral steel pipe.
4. Whether the spiral steel pipe is sprayed regularly.
5. During transportation, the upper part of the spiral steel pipe cannot be placed.
6. If the diameter of the spiral steel tube is small and requires a tube, you can only put on the bottom layer.
The application of spiral steel pipes in the oil industry is widely used. In the process of crude oil mining and storage, spiral steel pipes often need to be used to transport and store crude oil. Its corrosion resistance can effectively resist the erosion of the steel pipes of the corrosive liquid and effectively extend the service life of the steel pipe. In addition, spiral steel pipes are also widely used in oil and gas wells, oil pipelines and other aspects in the oil industry.
