Erection requirements for API standard 650 flexible liquid storage tanks

In order to ensure the safety of the vertical storage tank, API standard 650 flexible liquid storage tanks, the supplier should inspect the tank carefully before delivery. The failure of the tank body is mainly due to the weld and crack of the product. The inspection of API standard 650 flexible liquid storage tanks, vertical storage tank weld and microcrack is mainly to inspect the appearance forming quality of weld. The inspection contents include weld leg height, undercut, welding deformation, weld bead, arc pit, weld straightness, etc., as well as the internal quality of weld, such as slag inclusion, porosity, incomplete penetration, crack, incomplete fusion, etc.Inspection of low-pressure storage tank Butt-weldsComplete penetration and complete fusion is required (to the degree mandated by the acceptance criteria for examination method utilized) for welds joining tank wall plates to API standard 650 flexible liquid storage tanks tank wall plates. Examination for quality of welds shall be made using either the radiographic method specified in API 620 standard 7.15.1 and applied in 7.17, or alternatively, by agreement between the Purchaser and the Manufacturer, using the ultrasonic method specified in 7.15.3.1. In addition to the radiographic or ultrasonic examination, these welds shall also be visually examined as specified in 7.15.5. Furthermore, the Purchaser’s inspector may visually inspect all butt-welds for cracks, arc strikes, excessive undercuts, surface porosity, incomplete fusion, and other defects.Fabricated to API Standard 650 Welded Tanks for Oil Storage Shop Assembled API standard 650 flexible liquid storage tanks Storage Tanks, these tanks are commonly used at oil and natural gas terminals, API standard 650 flexible liquid storage tanks processing plants, and midstream facilities located along pipelines at the pumping, compression, or metering stations. API 650 storage tanks are designed and fabricated considering operating pressures up to 2.5 PSIG, corrosion allowance, wind loading, and seismicity.On November 1st, our company organized some of company staff to visit Zhengzhou Children Welfare Institute, and gave children cookies and toys, as well as concerns to the Children. With the development of the society, disabled children gets increasing concerns and help from all walks of life. Fortunately, Chinese Government gives high concern to the handicapped children and has built Children Welfare Institutes all over the country to guarantee their lives.It is a modern high-tech professional enterprise integrating scientific research, API standard 650 flexible liquid storage tanks production and sales.
