API 650 mechanically-anchored flat-bottom tanks roof load

The inner layer of API 650 tank is the same as that of single layer tank. It is made of high-quality steel plate in strict accordance with the standard of "steel welded atmospheric pressure vessel". The thickness of API 650 mechanically-anchored flat-bottom tanks steel plate reaches the standard and the service life is longer.

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%.

The elastic filling and sealing of floating roof API 650 mechanically-anchored flat-bottom tanks is to fill the elastic and changeable objects in the sealed envelope, and the sealing purpose depends on the compression deformation of the filler. This kind of sealing effect is good, the requirement of the geometry of tank wall is not too high, and the adaptability is strong. However, the elastic filling and sealing has poor wear resistance and is easy to deform and damage in long-term use.

The company has always been adhering to the business philosophy of "integrity-based, responsibility oriented, quality first, reputation first" and is committed to building a world-class steel materials and service provider. We will continue to work hard to carry forward the enterprise tenet of "quality is the life of the enterprise, survival by quality, development by reputation", and become an enterprise with strong vitality! We always keep it in mind that profit is important to enterprises. But what counts more is social responsibility.
