Impact Tests for High Alloys
Impact tests are not required for oil steel storage material nickel alloy welds made with electrodes/filler metals covered by AWS Specification A5.11 or AWS Specification A5.14, provided the nominal nickel content is 50% or greater, and the weld is deposited by the shielded metal-arc welding (SMAW), gas metal-arc welding (GMAW), gas tungsten-arc welding (GTAW), or plasma-arc welding (PAW) processes. When A5.11/A5.14 specifies the nickel content as a “remainder,” the nickel content shall be determined by summing the maximum specified values of the other elements (use the average specified value for elements with specified ranges) and subtracting from 100%.

There is a gap of 100 mm to 500 mm between the shell of API 650 crude oil storage API Std 650 self-anchored flat-bottom tanks tank and the floating plate of external floating roof to ensure that there is no chuck during operation. Use API Std 650 self-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.

Square hollow section S355J2H to Turkey. In January of 2015, our customer from Turkey chose us as their supplier of seamless RHS EN10219 S355J2H with a trail order of 120 tons. They required DNV test for the MTC and each tube. DNV inspector tested all the tubes and MTC. When our customer received the reports, they gave us a second order of 852.5 tons. Since then we maintain a long time cooperation relationship.

Static storage loss is also known as "small breathing" consumption. The rise and fall of the temperature in the API Std 650 self-anchored flat-bottom tanks leads to the increase and decrease of the pressure in the tank, which makes the mixed oil gas discharged from the tank, and the external air is sucked into the tank, resulting in the oil consumption. Fluid level loss is also called "big breathing" loss. It is the oil consumption caused by the change of gas space volume in the API Std 650 self-anchored flat-bottom tanks during the oil receiving and sending operation, which causes the mixed oil gas to be discharged out of the tank, and the external air is sucked into the tank, resulting in the oil consumption due to the change of liquid level height.
