API Std 650 horizontal tank tank shell

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 horizontal tank 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.

When the day light gradually decreases, the temperature of oil in the API Std 650 horizontal tank will also decrease, the evaporation speed will gradually slow down, and the pressure in the API Std 650 horizontal tank will also decrease. When the pressure in the API Std 650 horizontal tank is lower than the negative pressure rating of the breathing valve, the outside air is sucked into the API Std 650 horizontal tank 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 Std 650 horizontal tank is highly desired and the thermal post-heat treatment is impractical.

It is very important for an enterprise to have a sound after-sales service system, which not only ensures the normal outflow and inflow of the company's products, but also improves the trust of the company's products in the hearts of customers. Our company has a special after-sales service team and good after-sales service reputation. In case of any problem in the use of our steel products API Std 650 horizontal tank , whether quality problem or not, the after-sales service department will assist in solving the problem as soon as possible, and regularly consult and track the use of the steel products.

Our company doesn't need the cheapest quotation to choose international logistics company, but the price performance ratio will be high, the service will be good, and the transportation must be safe and punctual, which will not affect the time when the API Std 650 horizontal tank goods arrive at the destination, and the logistics situation will be well communicated with customers in advance. Therefore, when we choose international logistics companies, we will have a look at their timeliness and service attitude in advance. It is only important to transport goods according to the requirements of customers for logistics.
