API 650 flat-bottom steel tanks piping flexibility

According to API standard 650, the stairs used for API 650 petroleum storage tanks or thermal insulation tanks should be double longitudinal beams supported by a minimum of ribs. If the gap between the API 650 flat-bottom steel tanks tank shell and the stringer of the API 650 petroleum storage tank exceeds 200mm, handrails should be provided on both sides of the stairs. Unless otherwise specified, according to API 650 flat-bottom steel tanks ASTM A123, the following accessories shall be hot-dip galvanized. The damaged zinc coating should be repaired with zinc alloy.

Structural shapes of 9% and 5% nickel steel may be furnished to the chemical and physical requirements of ASTM A353, A553, or A645. Physical tests shall be in accordance with the requirements of ASTM A6.
API 650 flat-bottom steel tanks used Piping, Tubing, and Forgings
Material used for piping, tubing, and forgings shall be compatible in welding strength, and thermal expansion coefficient with the tank shell material. In addition to the specific requirements of this appendix, all piping within the limitations of 1.3.2 shall fulfill the minimum requirements of ASME B31.3.

According to the structure type of floating roof, floating roof API 650 flat-bottom steel tanks can be divided into internal floating roof tank and external floating roof storage tank. The internal floating roof tank is a floating roof tank with tank roof. The top is the combination of dome roof and floating roof, the external is dome roof, and the internal is floating roof. There is no vault on the top of the External floating roof tank, only a top plate floating with the storage liquid. The common feature of the inner floating roof tank and the outer floating roof tank is that both of them can reduce the evaporation loss of the storage liquid.

The API 650 flat-bottom steel tanks company has established the corporate values of being proud of innovation and winning, and successfully realized the management of corporate culture. In BBN, leaders are not controllers and supervisors, but earnest API 650 flat-bottom steel tanks teachers, coaches and enthusiastic friends, so that employees can have more democracy, more autonomy, independence and creativity, and the belief of winning.

Our company doesn't need the cheapest quotation to choose international logistics company, but the price performance ratio will be high, the service will be good, and the transportation must be safe and punctual, which will not affect the time when the API 650 flat-bottom steel tanks goods arrive at the destination, and the logistics situation will be well communicated with customers in advance. Therefore, when we choose international logistics companies, we will have a look at their timeliness and service attitude in advance. It is only important to transport goods according to the requirements of customers for logistics.
