API 650 stainless steel storage tanks lining
API was established in 1919. It is the first national-level business association in the United States. It is one of the earliest and most successful chambers of commerce in the world to formulate standards. An important task of API API 650 stainless steel storage tanks is to be responsible for API 650 oil storage tanks and natural gas. Standardization of industrial equipment to ensure the safety, reliability and interchangeability of equipment used in the industry.
Inspection of API 650 stainless steel storage tanks bottom: magnetic flux leakage scanning technology is used to detect the corrosion condition of API 650 stainless steel storage tanks bottom plate (such as corrosion depth and area, crack length, etc.). When there is a defect in the bottom plate of the API 650 stainless steel storage tanks, the magnetic field distribution will change and the sensor can detect it. The bottom of the oil tank should be free of foreign matters and dry during testing. Weld inspection of API 650 stainless steel storage tanks bottom plate: when vacuum leak test method is used to detect the tightness of oil tank bottom plate, soap water shall be applied to the weld and vacuum box shall be covered for observation.
Allowable compressive stresses shall be in accordance with 5.5.4 except that for aluminum alloy plate the allowable compressive stresses shall be reduced by the ratio of the modulus of compressive elasticity to 29,000 for values of (t – c)/R less than 0.0175 and by the ratio of the minimum yield strength for the aluminum alloy in question to 30,000 for values of (t – c)/R equal to or greater than 0.0175 (see 5.5.2 for definitions). In all other equations in this standard API 650 stainless steel storage tanks where yield strength or modulus of elasticity is used, such as Equations 27 and 28, similar corrections shall be made for aluminum alloys.
The impression of most customers who have cooperated with us on the company is being professional and responsible. That mainly owe to our united and considerate team members. For example, the professional technician, the responsible QC inspector, the experienced sales person, the rigorous document maker, the patient after-sales, etc. Their selfless devotion bring the customer good experience, and bring the company good reputation.
Accept the inquiry from the owner of the goods and the inquiry by sea: master the port and price from the port of shipment to all continents and routes, and the port and price that the owner often needs to serve; the shipping schedule information of the main shipping companies; when necessary, ask the owner of the inquiry for some category information, such as the name of the goods, the level of danger, etc. (water hazard code).
