A285C plates API Std 650 cylindrical welded storage tanks

If additional requirements are met, higher internal pressures are allowed. API 650 only covers tanks that support the whole bottom evenly and API Std 650 cylindrical welded storage tanks tanks in non-refrigerated service that have a maximum design temperature of 200 degrees F. It requires that you have a minimum material thickness of 3/16 inch.

During the use of API Std 650 cylindrical welded storage tanks, the tank material is prone to crack and leakage under the action of pressure, corrosion, wear and other conditions. Especially in the oil producing area, the temperature difference in four seasons is large and the natural environment is bad, which will accelerate the consumption of oil storage tank and cause many potential safety hazards. Therefore, the API Std 650 cylindrical welded storage tanks must undergo strict inspections before being put into use after the production and installation are completed, so as to avoid cracks and leakage in short-term use and affect production safety.

API 620 Crude Oil Tank Pneumatic Pressure
An air pressure equal to 1.25 times the pressure for which the vapor space is designed shall be applied to the enclosed space above the water level. In the case of a double-wall tank with an open-top inner tank, where the air pressure acts against the outer tank and the inner tank is thus not stressed by the air pressure, the inner API Std 650 cylindrical welded storage tanks may be emptied of water before the pneumatic pressure test begins. The test pressure shall be held for 1 hour.

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for API Std 650 cylindrical welded storage tanks various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several API Std 650 cylindrical welded storage tanks after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.
