The design of foundations for API 650 ground supported tanks

Tanks which are designed following rules and guidelines of API 650 are API 650 tanks. API 650 API 650 ground supported tanks is the governing code for Welded tanks for Oil storage normally operating in the atmospheric pressure range. The code API 650 provides guidelines for design, fabrication, material, erection, and inspection of welded vertical and cylindrical storage tanks. Such API 650 ground supported tanks Tanks must be above ground with a closed or open top.

API 620 Tank Standard Post-heat Treatment (Stress Relief)
The post-heat treatment now performed on pressure vessels is of established value, although the mechanism by which the improvement is realized may be open to debate. Post-heat treatment of API 650 ground supported tanks tank sections when the plate thickness exceeds 11/4 in. is required as stated in 5.25. In special cases, the possibilities of post-heat treatment after erection should be explored. Post-heating an insulated tank may be possible if an ample source of heat is readily available and if the rigidity of the tank is adequate.
The thermal stress-relief treatment performed on pressure vessels is recognized as a means for reducing the probability of brittle failures.

Treatment of API 650 ground supported tanks welding defects:
1. Lack of fusion: once found, it should be shoveled and grinded off before re welding.
2. Incomplete penetration: over standard defects shall be removed and re welded. When welding on both sides, the shallow side of the groove can be grinded and shoveled to expose the welding root on one side, and then the welding is repaired.
3. Slag inclusion: over standard defects shall be removed and re welded.
4. Crater: weld to full after grinding.
5. Air hole: if the internal air hole exceeds the standard, it shall be welded again after being removed by grinding shovel, and the surface air hole shall be removed by grinding wheel and then repaired.

The company always insists on quality first. "Tolerance and trust, change and innovation, abide by rules, and focus on refining people" are the eternal credo of the team. Encouraged by the same creed and belief, BEBON people continue to grow and mature, and the team size is increasing expand. In the future, look beyond Chinese private steel companies to see BEBON. Looking to the future, we are not blindly pursuing bigger scale, but we are pursuing strength and brand strength.

Using advanced logistics management, advanced models and management experience to increase the reliability of logistics operations and provide customers with 24/7 cargo management. On the premise of reducing transportation and management costs as much as possible, we provide customers with high-quality and efficient services; good business reputation has been recognized and supported by our customers.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel API 650 ground supported tanks plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
