CSA G40.21 Gr 350W plates API Std 650 open top welded storage tanks

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 open top welded storage tanks 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.

For the welding of API Std 650 open top welded storage tanks bottom, attention should be paid to the slag removal and drying of the welding joint before welding, and there is no sediment and oil contamination in the lap joint of steel plate. The manufacturing quality and production efficiency of the central plate can be obviously improved by adopting the rolling central plate. The butt joint is used between the rolling plates to improve the installation conditions of the central plate at the bottom of the API Std 650 open top welded storage tanks. The welding sequence of the central plate is from the center of the central plate to the surrounding.

Density of API Std 650 open top welded storage tanks Liquid Stored
The density of the liquid stored shall be its maximum density within the range of design temperatures, but no less than 29.3 lbf/ft3 for methane, 34.21 lbf/ft3 for ethane, and 35.5 lbf/ft3 for ethylene.
Design Metal Temperature
The design metal temperature of each component exposed to the liquid or vapor being stored shall be the lower of the temperatures specified as follows: The design metal temperature of the components of the API 620 single-wall tank or the inner tank of a double-wall tank shall be the minimum temperature to which the tank contents shall be refrigerated, including the effect of subcolony at reduced pressure."

Every customer who has visit us and witness the steel materials before delievry will be impressed by our quality control departemnt. Even not come to inspect the steel materials before delievry, our quality control departemnt will also send inspection report to the customer. For each order, no matter its quantity and value, our quality control departemnt will make strict inspection before delivery, the inspection contents include apperance, tolerance, dimension, mark, special requirements of customers, etc. To guarantee our steel materials sent to the customer is qualified.
