5052 aluminum tube API 650 welded steel storage tanks
The design metal temperature of API 650 welded steel storage tanks each component exposed to the liquid or vapor being stored shall be the lower of the following:a)The minimum temperature to which the tank contents will be refrigerated, including the effect of subcooling at reduced pressure.b)The minimum metal temperature anticipated when the atmospheric temperature is below the refrigerated temperature (see 4.2.1). The effectiveness of the insulation in keeping the metal temperature above the expected minimum atmospheric temperature shall be considered.
Floating roofs shall comply with API standard 650, Appendix C (Attachment 01) or with the API 650 welded steel storage tanks requirements as layed (laid )down in the national Chinese specifications SH3046-92 and GBJ128-90.
We have lots of successful cases, for example in July 2015, we exported 5714 tons ASTM A36 mild steel plate to Peru. After receiving the plates and putting then into use, our customer spoke highly of the ASTM A36 mild steel plate quality. In addition, the customer also introduced us an Venezuela customer, who bought 933 tons A36 steel API 650 welded steel storage tanks plate from us. And then in Mar. 2016, due to the first cooperation in July 2015 is very successful. The customer is very satisfied with our product quality and comprehensive service. This time, the customer place an 3989 tons order directly.
}Deformation of the welding seam of the API 650 welded steel storage tanks is a common quality problem during the actual use of the API 650 welded steel storage tanks, which easily causes the tank body to leak and affects the safety of the oil storage tank. The welding seam deformation of the API 650 welded steel storage tanks is mainly caused by the lack of reserved welding seam gap and irregular operation. The oil storage tank has not reserved the corresponding weld gap, resulting in deeper root removal during the front welding activity. The heat output of the weld will increase under the influence of a long time, and the deformation of the weld will gradually become serious.
We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
