CSA G40.21 grade 260W plates API 650 unanchored flat-bottom tank
Preheat TreatmentMany 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 650 unanchored flat-bottom tank is highly desired and the thermal post-heat treatment is impractical.
For areas with high groundwater levels, the operator should take anchoring and anti-floating measures for buried horizontal API 650 unanchored flat-bottom tank oil tanks; API 650 oil tanks can be used for heavy fuel oil, heaters are separately designed, and buried tank material outlets are installed with bottom valves and connections. consider.
We have built solid cooperation with Myanmar Navy since 2015, starting from a try order about 412 tons LR AH36 shipbuilding steel plates. Myanmar navy builds frigate every year and book shipbuilding steel materials from us regularly. This time, the Myanmar navy’s local representative visit us and put another order about 2025 tons LR grade A steel plates. According to clients requirements, we arranged API 650 unanchored flat-bottom tank SGS inspection for the LR grade A steel plates before shipping and send them inspection report.
}The safety inspection of atmospheric storage tank, API 650 unanchored flat-bottom tank is divided into external inspection, internal and external inspection and comprehensive inspection. External inspection shall be conducted at least once a year, internal and external inspection shall be conducted at least once every three years, and comprehensive inspection shall be conducted at least once every six years. The safety inspection of large atmospheric storage tanks, API 650 unanchored flat-bottom tank requires special attention: the parts where the liquid level often fluctuates, the parts that are susceptible to corrosion, and the parts that are deformed and worn during use should be checked.
In addition to quality assurance, service is also important for the competition of steel suppliers. All the after-sales service personnel of the company have received professional training and assessment. The steel products supplied by our company enjoy the life-long quality problem replacement service. In the process of using our steel API 650 unanchored flat-bottom tank products, if there is any problem, just contact us in time, and our after-sales service personnel will look for countermeasures and solve the problem with you as soon as possible.
