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 floating-roof tanks is highly desired and the thermal post-heat treatment is impractical.

Pipeline transportation of API 650 oil tank is not less than the maximum consumption of 3 to 5 days. The daily operating time of API Std 650 floating-roof tanks office buildings and fuel oil equipment is 12-16 hours; for high-end residential hotel buildings, the daily operating time is 16-24 hours.

In Nov, 2018, our Mozambique customer purchased from BBN company 500 tons carbon steel Q235B steel structure for building 10 units of gas station. We have been cooperate more than 5 years for providing plate and pipes and API Std 650 floating-roof tanks profile as beginning, and they are very satisfied with all the received Cargo. We extend in-house cutting, welding, grinding, bending and certification and testing of our products, on client demand. If you are interested in our steel structures or steel plate price, welcome to contact us.

API Std 650 floating-roof tanks, Oil tank is a large-scale storage equipment used to store oil materials. Usually, the service life of API Std 650 floating-roof tanks is related to the actual working conditions. The design service life of most oil tanks is 20 years, and some of them are 10-15 years. Generally, none of them is less than 10 years. However, the design service life of API Std 650 floating-roof tanks is on the one hand, which is an ideal state, but there are many objective factors in the actual process, it is impossible to achieve the designed service life. How to effectively increase the service life of API Std 650 floating-roof tanks?
