API Std 650 welded tanks for oil storage bottom plates

The tank wall design of API 650 oil storage tank. Since there is no ventilation pipe directly connected with the outside on the top of the API Std 650 welded tanks for oil storage tank, the ventilation between the inside and outside of API 650 oil storage tank is realized by the respiration valve. The constant pressure of the respiration valve is 0.3kPa, so the pressure on the top of the tank is 0.3kPa.

The normal operation of API Std 650 welded tanks for oil storage includes receiving oil, storing oil, sending oil and measuring oil. The correct use and operation of oil storage tank is directly related to the production safety and oil loss of oil tank. In order to use and operate the API Std 650 welded tanks for oil storage correctly, it is necessary to be familiar with and master the structure and performance of the API Std 650 welded tanks for oil storage and its accessories, such as the maximum storage capacity of the oil tank, the pressure range that can bear and the safety fabrication specification.

API 620 crude oil tank piping materials made according to ASTM A333 and A350 may be used at API Std 650 welded tanks for oil storage design metal temperatures no lower than the impact test temperature required by the ASTM specification for the applicable material grade without additional impact tests. For temperatures below those allowed by the ASTM specification, the following paragraph shall apply.

When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials API Std 650 welded tanks for oil storage. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.

With the development of multimodal transport in the international shipping market and the increase of the complexity of the integrated transport chain, modern ports, as the intersection of the three transportation modes of sea, land and air, are developing from traditional transfer and product distribution functions to all-round value-added services, becoming the central link connecting the world's production, exchange, distribution and consumption, and supporting the world economy and international trade An important part of the developed international circulation system.
