EN 10025 S355 plates API standard 650 mechanically-anchored flat-bottom tanks

There is a gap of 100 mm to 500 mm between the shell of API 650 crude oil storage API standard 650 mechanically-anchored flat-bottom tanks tank and the floating plate of external floating roof to ensure that there is no chuck during operation. Use API standard 650 mechanically-anchored flat-bottom tanks edge sealing system to reduce edge evaporation. The support legs of API 650 crude oil tank floating roof are usually movable and retractable and suspended in liquid.

API standard 650 mechanically-anchored flat-bottom tanks foam generator is a fire extinguishing device fixed on the oil tank. One end of the foam generator is connected to the foam pipeline, and one end is flanged on the top layer of the API standard 650 mechanically-anchored flat-bottom tanks wall. Fire extinguishing foam flows through the air intake entrance of the fire foam chamber, inhaling a large amount of air to form foam, and breaking through the insulating glass into the tank (glass thickness is not greater than 2mm), so as to achieve the purpose of fire fighting.

Preheating should be performed by heating and maintaining this heat in appreciable lengths of the joint to be welded, preferably using a strip burner with a mild flame rather than a harsh flame such as that from a cutting torch. Electrical strip heaters are available and have been found to be satisfactory. The preheat of 300°F should be checked with a temperature-sensitive crayon, or similarly accurate means, so that the steel 4 in. (or four times the API standard 650 mechanically-anchored flat-bottom tanks plate thickness, whichever is greater) on each side of the joint will be maintained at the minimum preheat temperature. Ring burners or heaters are recommended for nozzle and manway welds. At no time during the welding should the base metal fall below a temperature of 300°F.

Every customer who has visit us and witness the steel materials before delievry will be impressed by our quality control departemnt. Even not come to inspect the steel materials before delievry, our quality control departemnt will also send inspection report to the customer. For each order, no matter its quantity and value, our quality control departemnt will make strict inspection before delivery, the inspection contents include apperance, tolerance, dimension, mark, special requirements of customers, etc. To guarantee our steel materials sent to the customer is qualified.

In particular, the EU imports a large amount of iron ore from central and South America and Oceania, which are mainly transported by sea. The perfect port infrastructure makes the port operation cost of EU iron ore raw materials import relatively low. However, the API standard 650 mechanically-anchored flat-bottom tanks steel transportation between EU Member States is mainly railway transportation, and the EU member states have established a very developed railway network and railway information infrastructure.
