When the day light gradually decreases, the temperature of oil in the api 620 crude oil storage tank standard will also decrease, the evaporation speed will gradually slow down, and the pressure in the api 620 crude oil storage tank standard will also decrease. When the pressure in the api 620 crude oil storage tank standard is lower than the negative pressure rating of the breathing valve, the outside air is sucked into the api 620 crude oil storage tank standard through the open vacuum valve, which is the "suction" process of the oil tank.

Preheat Treatment
Many laboratory tests have shown preheat treatment of carbon steel to 300°F-400°F to be the equivalent of the post-heat treatment at no less than 1100°F insofar as the physical properties of the weldment are concerned.40,41 Some tests have indicated a slight advantage of the post-heat treatment. Most of the tests have been made on plates 3/4 in. - 1 in. thick; results must be viewed with caution if preheating is applied appreciably beyond this thickness range. However, for all practical purposes, improvement resulting from preheating is sufficiently well established so that preheat should be considered for field fabrication of API 620 crude oil tank plates over 3/4-in. thick whenever toughness of the tank api 620 crude oil storage tank standard is highly desired and the thermal post-heat treatment is impractical.

"Efficiency is benefit, time is money", the company is equipped with a high standard logistics team. After the products pass the factory inspection, they will coordinate the shipment as soon as possible according to customer requirements and schedules to hand over the booked steel materials to customers at the first time, to ensure no delay of customer's project progress, to strive for more project preparation time for customers.

Our company is a specialized technical support and after-sales service organization - customer service center. At the same time, we have provided excellent technical api 620 crude oil storage tank standard personnel and strong technical support for our company, and cultivated an excellent after-sales team for our company. Our company will appoint a full-time service manager to be responsible for the unified coordination of technical support and api 620 crude oil storage tank standard after-sales service of the project.
