API 5L grade B pipe API 650 storage tanks

API 650 petroleum storage tank specifications and standards are documents verified by the customer (owner) under different operating conditions; however, API 650 storage tanks it must be verified whether these API 650 petroleum storage tank documents are suitable for use and whether they comply with applicable design specifications and/or specifications.

The hot weather in summer brings great security challenges to the vertical oil storage tanks, API 650 storage tanks standing outdoors. We must find some simple and effective methods to protect the API 650 storage tanks in order to make them safely spend the summer. As a API 650 storage tanks manufacturer, in order to reduce the direct sunlight rate of the vertical oil tank, reduce the temperature change of the oil tank, and reduce the evaporation loss of the oil tank, we usually adopt the measures of applying sunscreen paint and washing with warm water.

In this project, an elemental area of API 620 oil storage tank wall is constructed of ASTM A516 Grade 55 steel plate subjected to a meridional unit force, T1, of 2620 lbf/in. tension and a latitudinal unit force, T2, of 2880 lbf/in. compression. The meridional radius of curvature, R1, is 132 in., and the length of the normal from the surface to the axis of revolution, R2, is 409 in. The joints in the wall are spot-radiographed, double-welded butt joints, and no corrosion allowance is required.
The problem in this example is to graphically find the minimum thickness of tank wall required for the given conditions (see API 620 tank standard 5.10.3.3).
Solution: As determined from Table 5-1, the maximum, allowable tensile stress value, Sts, for ASTM A516 Grade 55 steel plate in simple tension is 16,500 lbf/in.2. Since the compressive stress is latitudinal, the governing value of R for this situation is R1, or 132 in.

The company regularly holds sales elites to share experiences, to promote the rapid growth of colleagues, and achieve the company and employees. The company conducts employee skill training and related knowledge video learning from time to time. All these things is to improve the employees' skills and literacy, and reflects its own value. It has always been the pursuit of BBN steel to enhance the employee’s ability and keep up with the times.

Facing the new situation and facing new goals, the company revolves around the sixteen-character development policy of “prioritizing production preservation, society-oriented, market operation, and brand creation and efficiency”. Layout the country in accordance with the modern logistics model, and accelerate the establishment of a modern integrated steel enterprise integrating steel storage, transportation, processing, and distribution.
