API 650 flexible liquid storage tanks foam dam

Before pressure testing, thoroughly flush the API 650 tank floating roof primary drain hose system. Supply API 650 flexible liquid storage tanks blind flanges, gaskets, and bolting (for other types of blanking covers as may be required) necessary for testing.

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 650 flexible liquid storage 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.

All API 650 flexible liquid storage tanks fillet welds shall consist of a minimum of two passes. The ends of the fillet welds shall be 2 in. from the rat hole, and these welds shall be deposited by starting 2 in. from the rat hole and welding away from the rat hole. An acceptable alternative to stopping fillet welds 2 in. short of the rat hole would be to weld continuously through the rat hole from one side of the stiffener to the opposite side. All craters in fillet welds shall be repaired by back welding.
