API 650 mechanically-anchored steel tanks drains

API 650 petroleum storage tank body design is mainly the design of tank bottom, API 650 mechanically-anchored steel tanks tank top and tank wall, and the design of tank wall is particularly important. As the main pressure bearing part of API 650 petroleum storage tank, the tank wall bears loads including liquid pressure, wind pressure, seismic load, opening stress, etc. The calculation of such loads is explained in detail in various API 650 mechanically-anchored steel tanks storage tank design standards. But in addition, the API 650 petroleum storage tank wall also bears the push-pull force and torque of the connected pipeline.

The inner and outer tanks may be decoupled for seismic design of the tank and anchorage and assumed to act independently. However, if the inner and outer tanks API 650 mechanically-anchored steel tanks are supported by a common foundation, the seismic foundation loading shall be calculated using the lesser response modification values for either the inner tank or outer tank for both tanks and a dynamic analysis shall be performed to determine the combined effect.
Allowable Stresses: For Appendix R tanks, design allowable stresses shall be per API 620 large low pressure storage tank, Section R.3.3.

The factors that affect the "small breathing" loss of API 650 mechanically-anchored steel tanks are: 1. Generally, the larger the storage tank is, the larger the total open area is, the larger the evaporation area is, and the greater the "small breathing" loss is; conversely, the smaller the storage tank is, the smaller the evaporation area is and the smaller the "small breathing" loss is. 2. It is related to the atmosphere. The lower the atmospheric pressure is, the greater the "small breathing" loss is; otherwise, the loss is reduced.

The company operates on the principles of fairness, objectivity, science, pragmatism and integrity. The management treats people with courtesy, takes sincerity as the standard management, dares to open up, unites and advances, carries on the past and makes unremitting efforts, seizes the good trend of economic development, strengthens exchanges with peers, makes friends with all walks of life, keeps pace with the times and creates greater brilliance of the enterprise, and makes its own contribution to the prosperity and development of the steel industry.

In addition to our own truck fleet, we also have long-term cooperation with certain logistics companies to ensure that we can deliver API 650 mechanically-anchored steel tanks goods in time and smoothly. At the same time, because of the long-term cooperation and huge shipping volume, we can get a good transportation price and save transportation cost for the company and customers. Meanwhile, we have Shipping Department to arrange shipping work in advance. So as not to waste time on transportation both in land and on the sea.

The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
