API 650 stainless steel storage tanks seal membrane

API 650 petroleum storage tanks use lightning protection, anti-static, and fire protection measures. The internal corrosion protection should be determined according to the API 650 stainless steel storage tanks storage medium, and the outer wall corrosion protection should be determined according to the soil quality of the buried tank.

In this project a cylindrical tank 75 ft in diameter is designed for an internal pressure of 0.5 lbf/in.2 gauge in the vapor space. The plate material is ASTM A131 Grade B steel for thicknesses of 1/2 in. and less.
The top course of the butt-welded cylindrical sidewall is 1/4 in. thick. The tank API 650 stainless steel storage tanks roof is a conical shape with a 2:12 slope and a 1/4 in. thickness with single full-fillet welded lap joints. The maximum design liquid level is 6 in. below the plane of juncture of the roof and sidewall.

Crack treatment of API 650 stainless steel storage tanks weld area: find out the crack tip with ray or ultrasonic flaw detection, drill cut-off holes at both ends of the crack with the cut-off method, the hole depth is slightly greater than the crack depth, or groove (crack stop groove) is made by angle grinder at both ends of the crack, shovel and grind the whole crack, and grind it into a suitable groove; use radiographic inspection and dye detection to verify that the crack has been completely excavated, and finally repair welding.

The work concept attaches importance to talents, creates a high-income and high-standard employment mode and work mode, actively advocates all kinds of talents to inspire each other, respect each other, unite and act together, cultivates employees' corporate interests above all else, is tolerant and enterprising, learns correct ways of doing things, improves employees' Professional quality, encourages and urges employees to make continuous progress, Continuously realize self value and grow together with the enterprise.

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 stainless steel 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.
